BHK Practice 3 — Questions and Answers
Question 1: A kinesiologist is using the talk test during a graded exercise test. A client can no longer speak in full sentences comfortably. This corresponds MOST closely to which physiological threshold?
- Resting metabolic rate
- Ventilatory threshold (VT1) (Correct answer)
- Maximal oxygen uptake (VO2max)
- Anaerobic power peak
Correct answer: Ventilatory threshold (VT1)
The talk test closely tracks the first ventilatory threshold (VT1), the point where ventilation begins to increase disproportionately to workload.
Question 2: A high school athlete presents with shin splints (medial tibial stress syndrome). Which practice modification is MOST appropriate for initial management?
- Continue full training volume and add compression socks only
- Immediately prescribe complete bed rest for six weeks
- Reduce training load, address contributing biomechanical factors, and apply relative rest (Correct answer)
- Increase running mileage to build bone density faster
Correct answer: Reduce training load, address contributing biomechanical factors, and apply relative rest
Management of MTSS involves reducing mechanical stress through load modification while addressing stride mechanics, footwear, and muscle imbalances.
Question 3: In applied kinesiology practice, which outcome measure is MOST appropriate for assessing functional lower-extremity power in an elderly population?
- One-repetition maximum (1RM) leg press
- 30-second chair stand test (Correct answer)
- Wingate anaerobic cycling test
- Biodex isokinetic dynamometry at 300°/s
Correct answer: 30-second chair stand test
The 30-second chair stand test is a validated, safe, and functional measure of lower-extremity strength and power suitable for older adults.
Question 4: A kinesiologist is periodizing a strength program for an athlete in their off-season. Which training variable is MOST commonly manipulated to achieve hypertrophy during a mesocycle?
- Increasing rest intervals beyond 5 minutes per set
- Maintaining 1–3 reps at 95% 1RM throughout
- Targeting 6–12 repetitions at 67–85% 1RM with moderate rest periods (Correct answer)
- Performing only isometric contractions at joint angles below 30°
Correct answer: Targeting 6–12 repetitions at 67–85% 1RM with moderate rest periods
The hypertrophy rep range of 6–12 at 67–85% 1RM with 60–90 second rest periods maximizes mechanical tension and metabolic stress for muscle growth.
Question 5: 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)
- Pain-free jogging for 10 consecutive minutes
- Return of full range of motion in the uninvolved limb
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 6: 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?
- Increase the speed of overhead tasks to reduce total exposure time
- Redesign the workstation to keep work within shoulder-height reach zone (Correct answer)
- Prescribe daily static shoulder stretches without modifying the task
- Recommend the worker wear a rigid shoulder brace during all shifts
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 7: A kinesiologist administers a maximal graded exercise test and notes that a client's oxygen consumption plateaus despite increasing workload. This plateau is BEST described as:
- Respiratory compensation point
- VO2max (Correct answer)
- Anaerobic threshold
- Ventilatory equivalent for oxygen
Correct answer: VO2max
VO2max is defined as the highest oxygen consumption achieved where further increases in workload do not elicit further increases in VO2.
