BHK Practice 2 — Questions and Answers
Question 1: A kinesiologist is designing a warm-up protocol for a recreational soccer team. Which physiological benefit is the PRIMARY reason for including dynamic stretching over static stretching pre-exercise?
- Increases muscle fiber cross-sectional area
- Elevates muscle temperature and improves neuromuscular activation (Correct answer)
- Decreases resting heart rate before competition
- Maximizes lactate clearance prior to activity
Correct answer: Elevates muscle temperature and improves neuromuscular activation
Dynamic stretching raises intramuscular temperature and enhances neuromuscular readiness without reducing force production, unlike prolonged static stretching.
Question 2: 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
- Apply kinesiology tape to the ankle and proceed with training
Correct answer: Address hip mobility and single-leg stability deficits
A score of '1' on the hurdle step indicates limited mobility and stability in the hip, which must be corrected before loading the movement pattern.
Question 3: 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?
- Hip abductors and external rotators (Correct answer)
- Ankle plantarflexors
- Wrist extensors
- Cervical flexors
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 4: When applying the SAID principle (Specific Adaptations to Imposed Demands) in practice, a kinesiologist would MOST correctly design a program that:
- 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)
- Prioritizes maximum load on all exercises regardless of the client's current fitness level
- 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 5: A 65-year-old client with osteoporosis asks about safe resistance training. Which recommendation aligns BEST with evidence-based kinesiology practice?
- Avoid all resistance training due to fracture risk
- Prescribe high-impact plyometrics exclusively
- Include progressive weight-bearing and resistance exercises targeting major muscle groups (Correct answer)
- Limit all physical activity to aquatic exercise only
Correct answer: Include progressive weight-bearing and resistance exercises targeting major muscle groups
Progressive resistance and weight-bearing exercise stimulates bone remodeling and improves muscle strength, reducing fracture risk in individuals with osteoporosis.
Question 6: 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 light (below 40% HRmax)
- Light (40–55% HRmax)
- Somewhat hard (55–70% HRmax) (Correct answer)
- Very hard (85–94% 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 7: During a clinical kinesiology assessment, a practitioner notices a client has an anterior pelvic tilt at rest. Which muscle imbalance pattern BEST explains this posture?
- Tight hip flexors and weak gluteal/abdominal muscles (Correct answer)
- Tight hamstrings and weak quadriceps
- Tight ankle dorsiflexors and weak plantarflexors
- Tight scapular retractors and weak protractors
Correct answer: Tight hip flexors and weak gluteal/abdominal muscles
Anterior pelvic tilt results from tight iliopsoas/rectus femoris pulling the pelvis forward while weak glutes and abdominals fail to posteriorly tilt the pelvis.
