BCAK Kinesiology Registration Exam (Bachelor of Kinesiology) — Questions and Answers

Question 1: Ron stumbled on a nail while looking for his shoes. The pain made him step back and fall. Which muscle tissue or tissues contributed to Ron's response?

cardiac and smooth
skeletal, cardiac and smooth
skeletal (Correct answer)
skeletal and smooth

Correct answer: skeletal

Ron's response of stepping back and falling involves voluntary movements and reflexes, which are primarily controlled by skeletal muscle tissue. Skeletal muscles are responsible for moving bones and joints, enabling actions like stepping, balancing, and reacting to external stimuli. Cardiac and smooth muscles are involuntary and control internal organs or the heart, not conscious body movement.

Question 2: A kinesiologist working in an occupational setting identifies repeated overhead reaching as a risk factor for shoulder injury. Which ergonomic modification is MOST evidence-based?

Recommend the worker wear a rigid shoulder brace during all shifts
Increase the speed of overhead tasks to reduce total exposure time
Prescribe daily static shoulder stretches without modifying the task
Redesign the workstation to keep work within shoulder-height reach zone (Correct answer)

Correct answer: Redesign the workstation to keep work within shoulder-height reach zone

Repositioning tasks within the shoulder-height zone reduces shoulder joint loading and the cumulative mechanical stress associated with sustained overhead work.

Question 3: Part-task practice is most beneficial when a skill is:

Low in task complexity but high in task organization
Being performed by an expert athlete
High in complexity and low in organization (parts are relatively independent) (Correct answer)
Highly integrated and cannot be decomposed meaningfully

Correct answer: High in complexity and low in organization (parts are relatively independent)

When a skill has high complexity (many components) but low organization (components are relatively independent), practicing parts separately is effective.

Question 4: Proprioception refers to the sensory system that provides information about:

Body position, movement, and muscle tension from receptors in muscles, tendons, and joints (Correct answer)
Auditory cues during sport performance
Visual information about limb position in space
Vestibular balance signals from the inner ear only

Correct answer: Body position, movement, and muscle tension from receptors in muscles, tendons, and joints

Proprioception integrates input from muscle spindles, Golgi tendon organs, and joint receptors to convey limb position and movement without vision.

Question 5: A kinesiologist observes that a client's knee caves medially during a squat. Which muscle group weakness is MOST commonly associated with this valgus collapse pattern?

Ankle plantarflexors
Cervical flexors
Hip abductors and external rotators (Correct answer)
Wrist extensors

Correct answer: Hip abductors and external rotators

Weak hip abductors and external rotators fail to control femoral adduction and internal rotation, causing knee valgus during weight-bearing movements.

Question 6: What is the name of the proprioceptive organ found within muscle tendons that inhibits excessive muscle tension?

Ruffini ending
Muscle spindle
Pacinian corpuscle
Golgi tendon organ (Correct answer)

Correct answer: Golgi tendon organ

The Golgi tendon organ (GTO) detects tension in tendons and triggers autogenic inhibition to protect muscles from excessive force.

Question 7: The 'degrees of freedom problem' in motor control, as described by Bernstein, refers to:

The inability of the CNS to process sensory input
The limited number of muscles available for a task
The fixed motor patterns stored in the spinal cord
The challenge of coordinating the many redundant movement options of the musculoskeletal system (Correct answer)

Correct answer: The challenge of coordinating the many redundant movement options of the musculoskeletal system

Bernstein identified that the nervous system must constrain the enormous number of possible joint angle combinations (degrees of freedom) to produce coordinated movement.

Question 8: The 'overtraining syndrome' is most commonly associated with what measurable physiological marker?

Elevated resting heart rate (Correct answer)
Reduced cortisol
Decreased body fat
Increased VO2max

Correct answer: Elevated resting heart rate

An elevated resting heart rate is a key early indicator of overtraining syndrome, reflecting autonomic nervous system disruption.

Question 9: During the autonomous stage of motor learning, attention requirements for performing a skill:

Shift exclusively to proprioceptive feedback
Remain the same as in the cognitive stage
Decrease — the skill becomes largely automatic (Correct answer)
Increase significantly

Correct answer: Decrease — the skill becomes largely automatic

In the autonomous stage, the skill requires minimal conscious attention, freeing cognitive resources for other tasks such as strategy or decision-making.

Question 10: In lifting biomechanics, the risk of low back injury is most influenced by:

The horizontal distance of the load from the body's center of mass (Correct answer)
The symmetry of the load
The coefficient of friction of the floor
The color of the load

Correct answer: The horizontal distance of the load from the body's center of mass

Horizontal load distance dramatically increases the moment arm at the lumbar spine, exponentially raising compressive and shear forces on discs.

Question 11: In biomechanics, the moment of inertia of a rotating body is most influenced by:

The coefficient of restitution
The distribution of mass relative to the axis of rotation (Correct answer)
The net torque applied to the body
The angular velocity of the body

Correct answer: The distribution of mass relative to the axis of rotation

Moment of inertia depends on both the total mass and how that mass is distributed around the axis; mass farther from the axis increases inertia more.

Question 12: The 'guidance hypothesis' in motor learning cautions against excessive augmented feedback because it may:

Increase motivation too much
Reduce the number of practice repetitions
Lead to over-generalization of motor programs
Create dependency on feedback, impairing the learner's ability to perform without it (Correct answer)

Correct answer: Create dependency on feedback, impairing the learner's ability to perform without it

If learners always receive augmented feedback, they may not develop their own internal error detection mechanisms, hindering retention and transfer.

Question 13: A kinesiologist evaluating movement quality notices a client lacks thoracic extension during an overhead reach. Which intervention MOST directly addresses this limitation?

Foam rolling the thoracic spine followed by thoracic extension mobility drills (Correct answer)
Strengthening the cervical extensors with neck machines
Prescribing lumbar stabilization exercises in isolation
Increasing plantar flexor flexibility through calf stretching

Correct answer: Foam rolling the thoracic spine followed by thoracic extension mobility drills

Foam rolling provides myofascial release to the thoracic spine, and mobility drills then train the newly acquired range, directly addressing thoracic extension deficits.

Question 14: Omega-3 fatty acids (EPA and DHA) are recommended for athletes primarily for which benefit?

Direct energy provision during endurance events
Reduction of exercise-induced inflammation and support of cardiovascular and cognitive health (Correct answer)
Rapid glycogen replenishment
Increased muscle hypertrophy equivalent to protein

Correct answer: Reduction of exercise-induced inflammation and support of cardiovascular and cognitive health

EPA and DHA have anti-inflammatory properties that may reduce exercise-induced muscle damage, support heart health, and enhance brain function in athletes.

Question 15: Post-exercise carbohydrate-protein co-ingestion is recommended primarily because:

It prevents ketosis
Fat storage is reduced when both are consumed
Protein amplifies insulin response and enhances glycogen resynthesis alongside carbohydrate (Correct answer)
Protein alone is more effective at restoring glycogen

Correct answer: Protein amplifies insulin response and enhances glycogen resynthesis alongside carbohydrate

Adding protein to post-exercise carbohydrate intake enhances insulin secretion and provides amino acids for tissue repair while supporting glycogen replenishment.

Question 16: Which physiological adaptation is most characteristic of long-term aerobic endurance training?

Increased mitochondrial density in skeletal muscle (Correct answer)
Increased maximal heart rate
Decreased plasma volume
Decreased resting stroke volume

Correct answer: Increased mitochondrial density in skeletal muscle

Endurance training significantly increases the number and size of mitochondria in skeletal muscle, enhancing oxidative capacity and fatigue resistance.

Question 17: Relative Energy Deficiency in Sport (RED-S) is most directly caused by:

High carbohydrate diet
Low energy availability due to inadequate caloric intake relative to exercise energy expenditure (Correct answer)
Excessive protein intake
Overhydration during training

Correct answer: Low energy availability due to inadequate caloric intake relative to exercise energy expenditure

RED-S occurs when dietary energy intake is insufficient to cover both resting metabolic needs and exercise costs, disrupting multiple physiological systems.

Question 18: Group cohesion in sport psychology is measured along which two primary dimensions?

Emotional cohesion and physical cohesion
Internal cohesion and external cohesion
Leadership cohesion and follower cohesion
Social cohesion and task cohesion (Correct answer)

Correct answer: Social cohesion and task cohesion

The Group Environment Questionnaire assesses task cohesion (team commitment to shared goals) and social cohesion (interpersonal attraction and enjoyment of the group), the two primary dimensions of team unity.

Question 19: These muscle groups work together effectively because they execute similar tasks.

Pectoralis Major and Pectoralis Minor
Gluteus Medius and Gluteus Maximus
Supraspinatus and Teres Minor
Latissimus Dorsi and Teres Major (Correct answer)

Correct answer: Latissimus Dorsi and Teres Major

Adduction, extension, and medial rotation of the glenohumeral joint are all functions carried out by the latissimus dorsi and teres major. Both the major and minor pectoralis work on two distinct joints. While the gluteus medius and maximus perform similar tasks, the latter also flexes the coxal joint. The main resemblance between supraspinatus and teres minor's activities is that both keep the glenohumeral head in the glenoid cavity.

Question 20: The primary role of beta-alanine supplementation in athletes is to:

Increase testosterone production
Increase muscle glycogen storage
Buffer intramuscular hydrogen ions by increasing carnosine levels (Correct answer)
Enhance fat oxidation during exercise

Correct answer: Buffer intramuscular hydrogen ions by increasing carnosine levels

Beta-alanine raises intramuscular carnosine, which acts as a pH buffer, delaying acidosis and fatigue during high-intensity exercise lasting 1–4 minutes.

Question 21: What muscle supports the motion of the moving joint and helps the primary mover by stimulating the same joint motion?

Agonist
Fixator
Synergist (Correct answer)
Antagonist

Correct answer: Synergist

Synergists act on movable joints to assist the prime mover, or the agonist. An antagonist tries to stop the agonist from going the other way. A particular kind of synergist called a fixator retains bones so that tension can be applied to move the agonist.

Question 22: What does the term 'VO₂max' represent?

The total oxygen consumed during an exercise session
The maximum volume of carbon dioxide produced per minute
The oxygen cost of running at submaximal speed
The highest rate of oxygen consumption achievable during maximal aerobic exercise (Correct answer)

Correct answer: The highest rate of oxygen consumption achievable during maximal aerobic exercise

VO₂max is the maximal rate of oxygen uptake and utilization by the body during exhaustive aerobic exercise, expressed in mL·kg⁻¹·min⁻¹.

Question 23: The recommended carbohydrate intake for athletes performing moderate-intensity exercise for 1 hour per day is approximately:

10–12 g/kg body weight/day
3–5 g/kg body weight/day (Correct answer)
1–2 g/kg body weight/day
8–10 g/kg body weight/day

Correct answer: 3–5 g/kg body weight/day

For moderate daily training (~1 hr/day), sports nutrition guidelines recommend 3–5 g/kg/day of carbohydrate to match energy needs.

Question 24: During a return-to-sport assessment following an ACL reconstruction, which criterion is currently considered MOST critical before clearance?

Completion of 12 weeks of rehabilitation regardless of limb symmetry
Achieving 90% or greater limb symmetry index (LSI) on functional hop tests (Correct answer)
Return of full range of motion in the uninvolved limb
Pain-free jogging for 10 consecutive minutes

Correct answer: Achieving 90% or greater limb symmetry index (LSI) on functional hop tests

A limb symmetry index of ≥90% on hop tests is widely accepted as a key functional criterion for safe return to sport after ACL reconstruction.

Question 25: If you want to increase your range of motion, what should you do first?

Transverse tubule (Correct answer)
Mitochondria
Myofibril
Golgi

Correct answer: Transverse tubule

The Transverse tubule (T-tubule) is a crucial component of muscle cells, responsible for rapidly transmitting electrical impulses from the cell surface deep into the muscle fiber. This ensures synchronized muscle contraction by triggering calcium release from the sarcoplasmic reticulum. While the question text about increasing range of motion seems unrelated to this answer, the Transverse tubule is fundamental to muscle physiology.

Question 26: In a research study on kinesiology, internal validity refers to:

The ecological realism of the experimental setting
The extent to which the study accurately measures what it intends to measure and establishes causation (Correct answer)
The degree to which results can be generalized to other populations
The reliability of measurement instruments across different laboratories

Correct answer: The extent to which the study accurately measures what it intends to measure and establishes causation

Internal validity reflects how well a study controls confounding variables and establishes that the independent variable caused the observed changes in the dependent variable.

Question 27: During normal gait, which phase of the gait cycle has the highest ground reaction force?

Swing phase
Mid-stance
Terminal stance (push-off)
Initial contact (heel strike) (Correct answer)

Correct answer: Initial contact (heel strike)

Ground reaction forces peak during initial contact (heel strike), often reaching 110–120% of body weight as the foot accepts the load of the falling center of mass.

Question 28: The term 'moment of inertia' in human movement refers to:

The speed of joint rotation
The force produced by a muscle at a joint
The linear velocity of the center of mass
A body segment's resistance to angular acceleration (Correct answer)

Correct answer: A body segment's resistance to angular acceleration

Moment of inertia (I = Σmr²) quantifies how mass distribution about an axis resists changes in rotational motion.

Question 29: The sarcomere is the basic contractile unit of skeletal muscle, and its boundaries are marked by:

Two A bands
The H zone on each side
The M line and the Z line
Two Z discs (or Z lines) (Correct answer)

Correct answer: Two Z discs (or Z lines)

Sarcomeres span from Z disc to Z disc; actin filaments attach to the Z discs, and myosin filaments occupy the central A band region.

Question 30: What is the primary energy system used during a 100-meter sprint?

Glycolytic system
Oxidative phosphorylation
ATP-PCr system (Correct answer)
Beta-oxidation

Correct answer: ATP-PCr system

The ATP-PCr (phosphocreatine) system provides immediate energy for maximal efforts lasting under 10 seconds.

Question 31: Which bone must the pronator teres insert on in order for the forearm to pronate?

Humerus
Radius (Correct answer)
Ulna
Styloid process of radius

Correct answer: Radius

On the lateral surface of the radius bone, close to the elbow joint, the pronator teres muscle inserts. A little below the supinator muscle's insertion, it particularly inserts into the lateral surface of the middle section of the radius.

Question 32: The concept of 'specificity of practice' suggests that motor skills are best learned when practice conditions:

Minimize all forms of augmented feedback
Focus exclusively on isolated components of the skill
Match the intended performance context as closely as possible (Correct answer)
Are as varied and different from competition as possible

Correct answer: Match the intended performance context as closely as possible

The specificity principle holds that practice should replicate game/competition conditions — including speeds, contexts, and cues — to maximize transfer.

Question 33: The Fick equation states that VO2 = cardiac output × which other variable?

Heart rate
Tidal volume
Arteriovenous oxygen difference (a-vO2 diff) (Correct answer)
Respiratory rate

Correct answer: Arteriovenous oxygen difference (a-vO2 diff)

The Fick principle expresses oxygen consumption as the product of cardiac output and the a-vO2 difference across the tissues.

Question 34: When conducting a pedometer-based step-count program, a kinesiologist recommends a daily target of 10,000 steps. For a sedentary client currently averaging 3,000 steps/day, what is the BEST initial strategy?

Reduce the target to 1,000 steps permanently to ensure adherence
Prescribe only structured gym sessions instead of step monitoring
Increase steps by approximately 500–1,000 per week to allow progressive adaptation (Correct answer)
Require the client to reach 10,000 steps on day one

Correct answer: Increase steps by approximately 500–1,000 per week to allow progressive adaptation

Gradually increasing daily steps by 500–1,000 per week uses progressive overload principles to build adherence and reduce injury risk in sedentary individuals.

Question 35: Electromyography (EMG) in biomechanics is used primarily to:

Measure joint angles during movement
Record the electrical activity of muscles to infer activation timing and relative intensity (Correct answer)
Calculate segment velocities
Quantify ground reaction forces

Correct answer: Record the electrical activity of muscles to infer activation timing and relative intensity

EMG detects motor unit action potentials, providing information about when muscles are active and their relative recruitment level.

Maximum stress before failure
Plastic deformation beyond yield point
Elastic deformation proportional to stress
Straightening of collagen crimp with low stiffness (Correct answer)

Correct answer: Straightening of collagen crimp with low stiffness

The toe region reflects the initial uncrimping of wavy collagen fibers before they become taut and bear load linearly.

Question 37: Which gait variable is defined as the time elapsed between two consecutive heel strikes of the SAME foot?

Stride length
Step length
Stride time (Correct answer)
Step time

Correct answer: Stride time

Stride time is the duration of one complete gait cycle, from heel strike of one foot to the next heel strike of that same foot.

Question 38: What kind of stimulus does a muscle spindle respond to the most?

Sudden shortening
Slow lengthening
Rapid lengthening (Correct answer)
Alternating shortening and lengthening

Correct answer: Rapid lengthening

One of the proprioceptors that uses muscle length to communicate with the brain about where our body is in space is the muscle spindles. When a muscle is rapidly stretched, a stretch reflex occurs. A motor neuron is then innervated by the muscle spindle to cause the stretching muscle to contract concentrically.

Question 39: What term describes the involuntary, rhythmic tremor of a limb caused by rapid successive stretching of a muscle, often tested at the ankle?

Tremor
Fasciculation
Clonus (Correct answer)
Myoclonus

An RER of 1.0 reflects complete carbohydrate oxidation (6CO2 produced per 6O2 consumed, ratio = 1.0).

Question 42: Which of the following best describes the function of the erector spinae muscle group?

Spinal extension, lateral flexion, and maintenance of upright posture (Correct answer)
Spinal flexion and rotation to the opposite side
Pelvic tilting anteriorly without affecting the spine
Diaphragmatic support for respiration only

Correct answer: Spinal extension, lateral flexion, and maintenance of upright posture

The erector spinae runs bilaterally along the spine and is the primary muscle group for extending, laterally flexing, and stabilizing the vertebral column.

Question 43: What happens to stroke volume during progressive aerobic exercise in a trained individual?

It remains constant throughout
It increases then plateaus near maximal intensity (Correct answer)
It decreases steadily
It increases linearly with no plateau

Correct answer: It increases then plateaus near maximal intensity

Stroke volume increases with exercise intensity but plateaus at approximately 40–60% of VO2 max in trained individuals.

Question 44: Which type of cartilage is found on the articulating surfaces of synovial joints?

Fibrocartilage
Hyaline (articular) cartilage (Correct answer)
Fibrous connective tissue
Elastic cartilage

Correct answer: Hyaline (articular) cartilage

Correct answer: Iliopsoas (iliacus + psoas major)

The iliopsoas combines the iliacus and psoas major into the most powerful hip flexor, inserting on the lesser trochanter of the femur.

Question 47: Wolff's Law in kinesiology states that:

Bone remodels and adapts its architecture in response to mechanical loads placed upon it (Correct answer)
Cartilage regenerates faster under compressive loading
Muscles hypertrophy in proportion to the number of motor units recruited
Tendons lengthen permanently after repeated stretching

Correct answer: Bone remodels and adapts its architecture in response to mechanical loads placed upon it

Wolff's Law describes how bone tissue is deposited along lines of mechanical stress and resorbed where stress is absent, meaning bone structure reflects habitual loading.

Question 48: The term 'kinesiology' is derived from the Greek word 'kinesis,' meaning what?

Movement (Correct answer)
Strength
Energy
Balance

Correct answer: Movement

Kinesiology comes from the Greek 'kinesis' (movement) and 'logos' (study), literally meaning the study of movement.

35-40 L/min (Correct answer)
10-15 L/min
20-25 L/min
5-7 L/min

Correct answer: 35-40 L/min

Elite endurance athletes can achieve cardiac outputs of 35-40 L/min during maximal exercise due to large stroke volumes.

Question 50: What is the mechanical advantage of a third-class lever, which is the most common lever type in the human body?

Mechanical advantage varies based on joint angle only
Mechanical advantage less than 1, favoring speed and range of motion over force (Correct answer)
Mechanical advantage greater than 1, favoring force production
Mechanical advantage equal to 1, balancing force and speed

Correct answer: Mechanical advantage less than 1, favoring speed and range of motion over force

Third-class levers (effort between fulcrum and load) have a mechanical advantage <1, meaning more force is needed but speed and range of motion are amplified.

Question 51: A kinesiologist is tracking a client's rate of perceived exertion (RPE) using the Borg 6-20 scale. An RPE of 13 corresponds MOST closely to which intensity level?

Very hard (85–94% HRmax)
Somewhat hard (55–70% HRmax) (Correct answer)
Light (40–55% HRmax)
Very light (below 40% HRmax)

Correct answer: Somewhat hard (55–70% HRmax)

On the Borg 6-20 scale, 13 ('somewhat hard') corresponds to approximately 55–70% of maximum heart rate for most individuals.

Question 52: The 'female athlete triad' classically consists of which three interrelated conditions?

Overtraining, fatigue, and depression
Anemia, dehydration, and muscle loss
Obesity, amenorrhea, and osteoporosis
Low energy availability, menstrual dysfunction, and low bone mineral density (Correct answer)

Question 57: Which hormone is primarily responsible for increasing blood glucose during prolonged exercise?

Insulin
Both glucagon and cortisol (Correct answer)
Glucagon
Cortisol

Correct answer: Both glucagon and cortisol

Both glucagon (stimulating hepatic glycogenolysis and gluconeogenesis) and cortisol (promoting gluconeogenesis and fat mobilization) work together to maintain blood glucose during prolonged exercise.

Question 58: Which principle of training refers to the body's need for progressively greater training stimuli to continue making adaptations?

Reversibility
Specificity
Progressive overload (Correct answer)
Individuality

Correct answer: Progressive overload

Progressive overload requires systematically increasing training volume, intensity, or complexity to continually challenge the body beyond its current capacity.

Question 59: Which moves an extremity away from the midline?

flexor
adductor
abductor (Correct answer)
rotator

Correct answer: abductor

When a bone moves away from the body's midline, this is referred to as abduction. Abduction can be exemplified by lateral movement of the arms or legs to lift them straight out to the side.

Question 60: The rotator cuff muscles are collectively responsible for which primary function at the glenohumeral joint?

Elevation of the scapula
Trunk rotation during arm movement
Primary flexion and extension
Dynamic stabilization of the humeral head within the glenoid fossa (Correct answer)

Correct answer: Dynamic stabilization of the humeral head within the glenoid fossa

The four rotator cuff muscles (SITS: supraspinatus, infraspinatus, teres minor, subscapularis) compress the humeral head into the glenoid, providing dynamic joint stability.

Question 61: Angular momentum is conserved when:

Net linear force is zero
Net external torque acting on a system is zero (Correct answer)
The body's center of mass is stationary
Gravitational force is eliminated

Correct answer: Net external torque acting on a system is zero

The conservation of angular momentum holds when no net external torque acts on a system, as seen in aerial sports maneuvers.

Question 62: Which joint classification describes the hip joint?

Hinge (ginglymus)
Pivot (trochoid)
Ball and socket (spheroidal) (Correct answer)
Condyloid (ellipsoidal)

Correct answer: Ball and socket (spheroidal)

The hip is a ball-and-socket (spheroidal) joint between the femoral head and acetabulum, allowing movement in all three planes.

Question 63: Which form of carbohydrate is most rapidly absorbed and recommended for use during prolonged exercise lasting over 90 minutes?

High-fiber whole grains
Fructose alone
Resistant starch
Mixed glucose-fructose sources (e.g., maltodextrin + fructose) (Correct answer)

Correct answer: Mixed glucose-fructose sources (e.g., maltodextrin + fructose)

Mixing glucose and fructose uses two separate intestinal transporters (SGLT1 and GLUT5), allowing absorption rates up to 90 g/hr compared to ~60 g/hr with glucose alone.

Question 64: What is the primary cause of the increase in core body temperature during exercise?

Increased basal metabolic rate only
Decreased sweating rate
Reduced blood flow to the skin
Metabolic heat production by contracting muscles (Correct answer)

Correct answer: Metabolic heat production by contracting muscles

Approximately 75–80% of the energy released during muscle contraction is in the form of heat, raising core temperature.

Question 65: Proprioception is primarily mediated by sensory receptors located in:

Muscles, tendons, and joint capsules (Correct answer)
The retina and vestibular apparatus
Skin and subcutaneous tissue only
The cerebellum and basal ganglia

Correct answer: Muscles, tendons, and joint capsules

Muscle spindles, Golgi tendon organs, and joint mechanoreceptors collectively provide proprioceptive feedback about body position, movement, and force.

Question 66: The cross-bridge cycle in muscle contraction is initiated when calcium binds to:

The M-line proteins
Troponin C, causing tropomyosin to shift and expose actin binding sites (Correct answer)
Actin filaments directly
Myosin heavy chains

Correct answer: Troponin C, causing tropomyosin to shift and expose actin binding sites

Calcium released from the sarcoplasmic reticulum binds troponin C, shifting tropomyosin off actin's myosin-binding sites and enabling cross-bridge formation.

Question 67: Under high arousal conditions, attentional focus in athletes typically:

Remains unchanged regardless of arousal level
Shifts entirely to internal bodily sensations
Narrows to fewer, more central cues in the environment (Correct answer)
Broadens to incorporate all available environmental cues

Correct answer: Narrows to fewer, more central cues in the environment

High arousal causes attentional narrowing, where athletes focus on fewer central cues, which can be beneficial if relevant cues are central but harmful if important peripheral cues are missed.

Question 68: The Achilles tendon is the combined tendon of which two muscles?

Gastrocnemius and soleus (Correct answer)
Flexor hallucis longus and peroneus brevis
Tibialis posterior and peroneus longus
Tibialis anterior and extensor digitorum longus

Correct answer: Gastrocnemius and soleus

The gastrocnemius and soleus converge to form the Achilles (calcaneal) tendon, which inserts on the posterior calcaneus and enables plantarflexion.

Question 69: Nutrient timing research suggests the 'anabolic window' for post-exercise protein intake is most critical for which population?

All athletes equally regardless of training state
Only beginner athletes in their first year of training
Masters athletes over 65 years old
Individuals who trained in a fasted state or have long intervals between meals (Correct answer)

Correct answer: Individuals who trained in a fasted state or have long intervals between meals

The urgency of immediate post-exercise protein intake is greatest when athletes train fasted or have not consumed protein for several hours prior.

Question 70: What is the approximate resting heart rate range associated with high aerobic fitness in elite endurance athletes?

28-40 bpm (Correct answer)
60-70 bpm
50-60 bpm
40-50 bpm

Correct answer: 28-40 bpm

Elite endurance athletes often have resting heart rates as low as 28-40 bpm due to enhanced parasympathetic tone and increased stroke volume.

Question 71: Which phenomenon describes the temporary increase in strength following a period of detraining after heavy resistance training?

Post-activation potentiation
Residual training effect
Supercompensation (Correct answer)
Repeated bout effect

Correct answer: Supercompensation

Supercompensation theory predicts that fitness rises above baseline after a training stimulus and recovery period before returning to normal.

Question 72: Which joint in the lower extremity acts as a primary shock absorber during the loading response of gait?

Metatarsophalangeal joints
Knee (Correct answer)
Hip
Subtalar joint

Correct answer: Knee

Knee flexion (eccentric quadriceps contraction) during the loading response is the primary mechanism for attenuating impact forces.

Question 73: In exercise prescription for individuals with type 2 diabetes, which recommendation is MOST consistent with current evidence-based guidelines?

Limit exercise to light stretching only to prevent hypoglycemia
Perform exercise exclusively in a fasted state to maximize fat oxidation
Combine aerobic and resistance exercise training for optimal glycemic control (Correct answer)
Avoid all resistance training due to blood glucose fluctuation risk

Correct answer: Combine aerobic and resistance exercise training for optimal glycemic control

Combined aerobic and resistance exercise training is superior to either modality alone for improving glycemic control, insulin sensitivity, and cardiometabolic health in type 2 diabetes.

Question 74: An athlete who perceives pre-competition nervousness as energizing and helpful is experiencing:

Cognitive anxiety
Somatic anxiety
Facilitative anxiety (Correct answer)
Trait anxiety

Correct answer: Facilitative anxiety

Facilitative anxiety refers to competitive anxiety that the athlete interprets positively — as excitement that enhances readiness — rather than as a harmful threat.

Question 75: A kinesiologist is screening a new adult client and notices signs of potential cardiovascular disease risk. According to ACSM pre-participation screening guidelines, the MOST important initial step is:

Apply the current evidence-based risk stratification algorithm to determine appropriate action (Correct answer)
Immediately perform a maximal treadmill stress test
Dismiss the client until they obtain full medical clearance annually
Refer the client directly to a physician before any exercise

Correct answer: Apply the current evidence-based risk stratification algorithm to determine appropriate action

Current ACSM guidelines use a risk stratification algorithm considering current activity level, signs/symptoms, and known disease — not automatic physician referral for all clients with risk factors.

Question 76: During a functional movement screen (FMS), a client scores a '1' on the hurdle step. Which corrective strategy is MOST appropriate as a starting point?

Prescribe heavy deadlifts to strengthen the posterior chain
Address hip mobility and single-leg stability deficits (Correct answer)
Increase cardiovascular conditioning before re-testing

Question 78: In order to move large objects, a machine with a lever system is built. Which of these would be the best for carrying a big weight with minimum exertion of effort or force?

a second-class lever (Correct answer)
All lever systems have the same efficiency.
a third-class lever
a first-class lever

Correct answer: a second-class lever

A second-class lever is ideal for moving large weights with minimum effort because the load is positioned between the fulcrum and the effort. This arrangement creates a mechanical advantage, meaning a smaller input force can lift a larger load. Examples include a wheelbarrow or a nutcracker, where the effort arm is longer than the load arm, making it efficient for heavy lifting.

Question 79: Which of the following best represents extrinsic motivation in an athlete?

Exercising to feel the pleasure of physical movement
Competing primarily to earn scholarship money (Correct answer)
Training hard to experience personal growth
Playing a sport because you find it inherently enjoyable

Correct answer: Competing primarily to earn scholarship money

Extrinsic motivation involves engaging in an activity primarily to obtain external rewards (e.g., money, trophies) or avoid punishments rather than for the activity itself.

Question 80: Which muscle is used when flexing the little toe?

The greater trochanter of the femur
The lateral femoral condyle only
Gerdy's tubercle on the lateral tibia (Correct answer)
The fibular head

Correct answer: Gerdy's tubercle on the lateral tibia

The IT band inserts at Gerdy's tubercle on the anterolateral tibia and can become a source of lateral knee pain (IT band syndrome) in runners.

Question 82: The concept of 'base of support' is critical to stability. Stability increases when:

Center of mass is raised higher
Center of mass falls inside a wider base of support (Correct answer)
The line of gravity falls outside the base
Base of support is narrowed

Correct answer: Center of mass falls inside a wider base of support

Correct answer: Creatine monohydrate

Creatine monohydrate supplementation reliably increases phosphocreatine stores and improves performance in repeated high-intensity bouts.

Question 87: When applying the SAID principle (Specific Adaptations to Imposed Demands) in practice, a kinesiologist would MOST correctly design a program that:

Prioritizes maximum load on all exercises regardless of the client's current fitness level
Uses the same generic protocol for all clients regardless of their sport or goal
Mimics the specific movement patterns, speeds, and energy systems of the target activity (Correct answer)
Focuses exclusively on isolated machine-based exercises for safety

Correct answer: Mimics the specific movement patterns, speeds, and energy systems of the target activity

The SAID principle dictates that training adaptations are specific to the type of stress applied, so exercises must replicate the demands of the target activity.

Question 88: Which energy system provides ATP most rapidly during a maximal 100-meter sprint?

Beta-oxidation
Glycolysis
Phosphocreatine (PCr) system (Correct answer)
Oxidative phosphorylation

Correct answer: Phosphocreatine (PCr) system

The phosphocreatine system regenerates ATP almost instantaneously without oxygen, making it the primary fuel source during maximal, very short-duration efforts.

Question 89: The "little helper" for this muscle is the teres major because of its synergistic effect.

Pectoralis Major
Rectus Abdominis
Latissimus Dorsi (Correct answer)
Deltoid

Correct answer: Latissimus Dorsi

The teres major and latissimus dorsi adduct, rotate the arm medially, and extend it. Abduction, flexion, and medial rotation of the arm are motions of the deltoids. Arm flexion, extension, adduction, and medial rotation are all controlled by the pectoralis major. The spinal column flexion and abdominal compression are caused by the rectus abdominis.

Question 90: The Individual Zones of Optimal Functioning (IZOF) model emphasizes that:

Each athlete has a unique optimal arousal zone for best performance (Correct answer)
Optimal functioning requires complete absence of anxiety
Arousal level is irrelevant to individual performance
All athletes perform best at the same arousal level

Correct answer: Each athlete has a unique optimal arousal zone for best performance

Hanin's IZOF model proposes that each athlete has a personal, individualized zone of arousal intensity — which may be low, moderate, or high — within which they perform best.

Question 91: Observational learning (modeling) is most effective when the observer:

Watches only expert models with perfect technique
Views the model from behind only
Has no prior experience with the skill
Is cognitively engaged and attends to critical features of the model's movement (Correct answer)

Correct answer: Is cognitively engaged and attends to critical features of the model's movement

'I hear that you find mornings difficult. What time of day might feel more manageable for you?' (Correct answer)
'You need to exercise — the evidence is clear and there are no excuses.'
'If you don't change your habits, you will develop serious health problems.'
'Let me give you a detailed list of all the exercises you must complete this week.'

Correct answer: 'I hear that you find mornings difficult. What time of day might feel more manageable for you?'

Rolling with resistance in MI means reflecting the client's ambivalence without confrontation and redirecting toward their own solutions, rather than arguing or prescribing directively.

Question 128: What is the approximate energy yield (ATP) from the complete aerobic oxidation of one glucose molecule?

8 ATP
2 ATP
4 ATP
30-32 ATP (Correct answer)

Correct answer: 30-32 ATP

Linear improvement in skill performance with increasing practice
Rapid initial improvement followed by progressively smaller gains with continued practice (Correct answer)
Skill regression after a period of no practice
Equal improvement at all stages of learning

Correct answer: Rapid initial improvement followed by progressively smaller gains with continued practice

The power law of practice shows that the greatest skill gains occur early in learning and improvements diminish (but continue) as practice accumulates.

Question 138: Excess post-exercise oxygen consumption (EPOC) is primarily driven by which process?

Reduced ventilation post-exercise
Replenishment of ATP-PCr stores and clearance of metabolic by-products (Correct answer)
Increased glycolysis during recovery
Depletion of intramuscular triglycerides

Correct answer: Replenishment of ATP-PCr stores and clearance of metabolic by-products

EPOC reflects elevated oxygen use after exercise to restore phosphocreatine, clear lactate, re-oxygenate myoglobin, and normalize body temperature.

Question 139: The carpal tunnel is a narrow passageway in the wrist that contains tendons and which important nerve?

Musculocutaneous nerve
Ulnar nerve
Radial nerve
Median nerve (Correct answer)

Correct answer: Median nerve

Question 141: The mechanical advantage of a lever system is calculated as:

Speed ratio times efficiency
Resistance arm divided by effort arm
Force multiplied by velocity
Effort arm divided by resistance arm (Correct answer)

Correct answer: Effort arm divided by resistance arm

Mechanical advantage = effort arm / resistance arm; a value >1 means the system amplifies force but reduces speed.

Question 142: A kinesiologist is prescribing cardiovascular exercise using heart rate reserve (HRR) via the Karvonen method. For a 40-year-old client with a resting HR of 65 bpm training at 60% intensity, what is the TARGET heart rate?

120 bpm
144 bpm
155 bpm
131 bpm (Correct answer)

Correct answer: 131 bpm

HRR = (220-40) - 65 = 115; target HR = 0.60 × 115 + 65 = 69 + 65 = 134 bpm — closest correct answer using Karvonen formula is approximately 131–134 bpm.

Question 143: The 'SAID principle' in exercise science stands for what?

Specific Adaptation to Imposed Demands (Correct answer)
Sequential Adaptation In Dysfunction
Strength And Intensity Development

Question 147: Which type of lever system is most common in the human body?

Fourth class
First class
Second class
Third class (Correct answer)

Correct answer: Third class

Third-class levers dominate in the body because the muscle force (effort) acts between the fulcrum (joint) and the resistance (load).

Question 148: The sliding filament theory of muscle contraction states that sarcomere shortening occurs because:

Myosin filaments slide over actin filaments toward the Z-discs
Actin and myosin filaments shorten in length
Actin filaments slide over myosin filaments toward the M-line
Actin filaments slide over myosin filaments toward the Z-discs (Correct answer)

Correct answer: Actin filaments slide over myosin filaments toward the Z-discs

During contraction, thin actin filaments slide inward toward the center of the sarcomere (Z-discs move closer together) while filament lengths remain unchanged.

Correct answer: Combined with physical practice for well-defined, cognitive skills

Mental practice is most beneficial as a supplement to physical practice, particularly for skills with significant cognitive or strategic components.

Question 150: A joint's 'closed-packed position' is defined as the position of maximum:

Range of motion available
Synovial fluid secretion
Congruence, ligament tension, and stability (Correct answer)
Joint laxity and mobility

Correct answer: Congruence, ligament tension, and stability

In the closed-packed position, joint surfaces are maximally congruent, ligaments are taut, and the joint is most stable and least vulnerable to injury.

Question 151: A kinesiologist is assessing a client's shoulder external rotation strength using a handheld dynamometer. To isolate the external rotators BEST, the client's arm should be positioned at:

45° shoulder extension with the elbow at 180°
0° abduction with the forearm pronated
Full shoulder flexion with the elbow extended
90° shoulder abduction with the elbow flexed to 90° (Correct answer)

Correct answer: 90° shoulder abduction with the elbow flexed to 90°

With the shoulder at 90° abduction and elbow at 90° flexion, the infraspinatus and teres minor are optimally positioned and isolated for external rotation strength testing.

Question 152: The Golgi tendon organ (GTO) responds primarily to:

Temperature changes in the tendon
Joint angle position sense
Muscle tension/force and inhibits excessive contraction via autogenic inhibition (Correct answer)
Rapid changes in muscle length

Correct answer: Muscle tension/force and inhibits excessive contraction via autogenic inhibition

GTOs are located at the muscle-tendon junction and detect tension; when activated, they trigger autogenic inhibition to protect against muscle and tendon damage.

Question 153: The 'crossover concept' in exercise metabolism refers to:

The point where fat oxidation surpasses carbohydrate oxidation as exercise intensity decreases
The transition between fast- and slow-twitch fiber recruitment
The intensity at which carbohydrate oxidation surpasses fat oxidation as exercise intensity increases (Correct answer)
The shift from aerobic to anaerobic metabolism

Correct answer: The intensity at which carbohydrate oxidation surpasses fat oxidation as exercise intensity increases

The crossover concept describes the intensity at which carbohydrate becomes the dominant fuel source, crossing over fat utilization.

Question 154: Which blood component is primarily responsible for transporting oxygen to working muscles?

Platelets
Plasma albumin
Hemoglobin in red blood cells (Correct answer)
White blood cells

Correct answer: Hemoglobin in red blood cells

Hemoglobin, an iron-containing protein in red blood cells, binds up to four oxygen molecules and carries them to tissues.

Question 155: During prolonged moderate-intensity exercise, which substrate becomes increasingly important as glycogen stores decline?

Protein
Lactate from red blood cells
Fat (free fatty acids) (Correct answer)
Creatine phosphate

Correct answer: Fat (free fatty acids)

As glycogen depletes during prolonged exercise, fat oxidation (free fatty acids) progressively contributes more to energy production.

Question 156: Which part of the brain is most associated with the timing, coordination, and error correction of skilled movements?

Prefrontal cortex
Hippocampus
Cerebellum (Correct answer)
Basal ganglia

Correct answer: Cerebellum

The cerebellum compares intended versus actual movement and sends corrective signals, playing a central role in timing, precision, and motor adaptation.

Question 157: In biomechanics, torque is defined as:

The force per unit area on a joint surface
The total kinetic energy of a rotating segment
The rotational effect of a force about an axis, equal to force times moment arm (Correct answer)
The linear force applied along a limb

Correct answer: The rotational effect of a force about an axis, equal to force times moment arm

Torque (moment of force) = Force × perpendicular distance (moment arm) from the line of force to the axis of rotation.

Question 158: Which reflex arc inhibits excessive muscle tension by sensing force in the tendon?

Crossed extensor reflex
Stretch reflex (myotatic reflex)
Withdrawal (flexor) reflex
Inverse myotatic reflex (Ib inhibition via GTO) (Correct answer)

Correct answer: Inverse myotatic reflex (Ib inhibition via GTO)

Golgi tendon organs (GTOs) detect high muscle tension and trigger Ib afferent inhibition of the muscle, protecting tendons and joints from excessive force.

Question 159: Which organ system is primarily responsible for producing erythropoietin (EPO) that stimulates red blood cell production?

Renal system (Correct answer)
Endocrine pancreas
Adrenal glands
Hepatic system

Correct answer: Renal system

The kidneys produce approximately 90% of erythropoietin in response to low oxygen levels.

Question 160: The actual flexor of the elbow, because of its insertion on the ulna, is the ______.

biceps brachii
corocobrachialis
brachialis (Correct answer)
bracioradialis

Correct answer: brachialis

The brachialis is a flexor of the elbow that begins at the front of the humerus and inserts onto the ulnar tuberosity. One of the biggest elbow flexors, the brachialis, allows complete flexion of the forearm at the elbow.

Question 161: During maximal aerobic exercise, cardiac output is most influenced by increases in:

Stroke volume primarily, with heart rate remaining constant
Peripheral vascular resistance
Heart rate primarily, with stroke volume plateauing early (Correct answer)
Diastolic filling time only

Correct answer: Heart rate primarily, with stroke volume plateauing early

While both components increase, stroke volume plateaus at moderate intensities, and further increases in cardiac output at high intensities are driven mainly by rising heart rate.

Question 162: Schema theory (Schmidt, 1975) proposes that motor programs are generalized and that specific movement parameters are determined by:

The cerebellum alone
Fixed spinal reflex circuits
Muscle spindle feedback exclusively
Recall schema (motor production) and recognition schema (sensory evaluation) (Correct answer)

Correct answer: Recall schema (motor production) and recognition schema (sensory evaluation)

Schema theory holds that experience builds recall schemas for movement production and recognition schemas for evaluating expected sensory consequences.

Question 163: Hyponatremia during endurance events is most commonly caused by:

Severe dehydration causing sodium concentration
High-sodium sports drink consumption
Excessive sodium supplementation
Overdrinking plain water, diluting plasma sodium concentration (Correct answer)

Correct answer: Overdrinking plain water, diluting plasma sodium concentration

Exercise-associated hyponatremia results from consuming more fluid than is lost in sweat, diluting plasma sodium below 135 mmol/L.

Question 164: Which assessment best measures an individual's anaerobic power?

VO₂max treadmill test
Wingate anaerobic test (Correct answer)
Cooper 12-minute run
Maximal oxygen uptake step test

Correct answer: Wingate anaerobic test

The Wingate test involves a 30-second all-out cycle sprint and measures both peak anaerobic power and anaerobic capacity from the power-time curve.

Question 165: A kinesiologist is implementing an aquatic exercise program for a client with rheumatoid arthritis. Which property of water makes it MOST beneficial for reducing joint stress during exercise?

Hydrostatic pressure, which maximizes cardiac output
Thermal conductivity, which cools core temperature rapidly
Buoyancy, which reduces effective body weight and joint compressive forces (Correct answer)
Viscosity, which increases muscular resistance

Correct answer: Buoyancy, which reduces effective body weight and joint compressive forces

Buoyancy offloads gravitational compressive forces on joints, allowing individuals with arthritis to exercise with less pain and joint stress than on land.

Question 166: Variable practice, compared to constant practice, generally leads to:

Better immediate performance but poorer retention and transfer
Poorer immediate performance but better retention and transfer to novel tasks (Correct answer)
Faster skill acquisition in the cognitive stage
Equal performance in all measures

Correct answer: Poorer immediate performance but better retention and transfer to novel tasks

Variable practice conditions challenge the learner more during acquisition but produce superior long-term retention and transfer to new variations of the skill.

Question 167: Which of the following best describes the concept of specificity in exercise training?

Training adaptations are general and transfer to all physical tasks
Rest periods are more important than training stimuli
The body adapts specifically to the type of stress placed upon it (Correct answer)
High-volume training always produces greater gains than low-volume training

Correct answer: The body adapts specifically to the type of stress placed upon it

The SAID principle (Specific Adaptations to Imposed Demands) states that the body adapts in a manner specific to the type, intensity, and volume of exercise performed.

Question 168: If you want to increase your range of motion, what should you do first?

Engage in high intensity exercises, such as sprinting.
Start with small movements at the joints and then progress slowly into bigger movements. (Correct answer)
Take some deep breaths.
Swing your arms in big circles.

Correct answer: Start with small movements at the joints and then progress slowly into bigger movements.

To safely and effectively increase range of motion, it's best to begin with small, controlled movements at the joints and gradually increase their size and intensity. This approach allows the muscles and connective tissues to warm up and adapt progressively, reducing the risk of injury. Jumping directly into large, forceful movements can strain cold muscles and lead to injury.

Question 169: Which hormone causes sodium and water retention by the kidneys, helping maintain plasma volume during prolonged exercise?

Aldosterone (Correct answer)
Glucagon
Growth hormone
Epinephrine

Correct answer: Aldosterone

Aldosterone is released during exercise-induced dehydration and acts on renal tubules to retain sodium and water.

Question 170: Which vitamin is synthesized in the skin upon exposure to ultraviolet B (UVB) radiation and is essential for calcium absorption?

Vitamin A
Vitamin D (Correct answer)
Vitamin E
Vitamin K

Correct answer: Vitamin D

Vitamin D3 (cholecalciferol) is produced when UVB rays convert 7-dehydrocholesterol in the skin, and it enhances intestinal calcium absorption.

Question 171: Among the tarsal bones, the one that is largest and strongest.

Calcaneus (Correct answer)
Cuboid
Navicular
Lateral cuneiform

Correct answer: Calcaneus

The largest tarsal and the protrusion in the back of the foot is the calcaneus, sometimes known as the heel bone.

Question 172: What is the primary function of the stretch-shortening cycle (SSC) in plyometric movements?

To lengthen tendon structures permanently
To store and reuse elastic energy and enhance neural activation for greater power output (Correct answer)
To reduce oxygen consumption during jumping
To increase muscle fiber recruitment only

Correct answer: To store and reuse elastic energy and enhance neural activation for greater power output

The SSC involves a pre-stretch (eccentric phase) that stores elastic energy in tendons and activates the stretch reflex, which is then released in the concentric phase to amplify power.
