BHK Bachelor of Kinesiology MCQ 4 — Questions and Answers
Question 1: Proprioception is primarily mediated by sensory receptors located in:
- Skin and subcutaneous tissue only
- The retina and vestibular apparatus
- Muscles, tendons, and joint capsules (Correct answer)
- 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 2: 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 3: During a bicep curl, which muscle acts as the primary agonist?
- Triceps brachii
- Brachioradialis
- Biceps brachii (Correct answer)
- Anterior deltoid
Correct answer: Biceps brachii
The biceps brachii is the primary mover (agonist) for elbow flexion during a bicep curl, assisted by the brachialis and brachioradialis as synergists.
Question 4: What does the term 'VO₂max' represent?
- The maximum volume of carbon dioxide produced per minute
- The highest rate of oxygen consumption achievable during maximal aerobic exercise (Correct answer)
- The oxygen cost of running at submaximal speed
- The total oxygen consumed during an exercise session
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 5: In the context of motor learning, the 'power law of practice' describes:
- Linear improvement in skill performance with increasing practice
- Rapid initial improvement followed by progressively smaller gains with continued practice (Correct answer)
- Equal improvement at all stages of learning
- Skill regression after a period of no practice
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 6: A kinesiologist uses the concept of 'center of mass' primarily to:
- Calculate the total weight of an athlete's equipment
- Determine the point where the body's total mass can be considered concentrated for mechanical analysis (Correct answer)
- Measure muscular power output during jumping
- Assess cardiovascular endurance capacity
Correct answer: Determine the point where the body's total mass can be considered concentrated for mechanical analysis
The center of mass is the theoretical point where all body mass is concentrated; analyzing its position and trajectory is fundamental to understanding balance and movement mechanics.
Question 7: Which connective tissue structure directly connects muscle to bone?
- Ligament
- Cartilage
- Tendon (Correct answer)
- Fascia
Correct answer: Tendon
Tendons are dense regular connective tissue composed primarily of collagen that transmit the force generated by muscles to bones, enabling movement.
