SCS Assessment & Performance Testing 2 — Questions and Answers
Question 1: Which protocol is most appropriate for assessing anaerobic power in a collegiate sprinter?
- 30-second Wingate test (Correct answer)
- VO2max treadmill test
- Beep test
- 6-minute walk test
Correct answer: 30-second Wingate test
The 30-second Wingate cycle ergometer test measures peak and mean anaerobic power output, making it ideal for sprinters.
Question 2: When assessing a client's posture in the sagittal plane, which deviation is characterized by excessive anterior pelvic tilt and lumbar lordosis?
- Lower crossed syndrome (Correct answer)
- Upper crossed syndrome
- Sway-back posture
- Flat-back posture
Correct answer: Lower crossed syndrome
Lower crossed syndrome (Janda) presents with tight hip flexors and lumbar extensors causing anterior pelvic tilt and increased lumbar lordosis.
Question 3: What is the primary purpose of the Y-Balance Test (YBT)?
- Assess dynamic balance and movement asymmetries (Correct answer)
- Measure static postural sway
- Evaluate aerobic endurance
- Test ankle plantarflexion strength
Correct answer: Assess dynamic balance and movement asymmetries
The YBT challenges dynamic single-leg balance in three reach directions and identifies functional asymmetries that may predict injury risk.
Question 4: A strength coach records a 1RM back squat of 200 kg and a body mass of 100 kg. What is the athlete's relative strength ratio?
- 2.0 (Correct answer)
- 1.5
- 0.5
- 200
Correct answer: 2.0
Relative strength is calculated by dividing the 1RM load (200 kg) by body mass (100 kg), yielding a ratio of 2.0.
Question 5: Which assessment tool is best suited for quantifying an athlete's reactive strength during plyometric activities?
- Drop jump with contact mat (Correct answer)
- Seated medicine ball throw
- 3RM leg press
- Grip dynamometry
Correct answer: Drop jump with contact mat
A drop jump performed on a force plate or contact mat calculates the reactive strength index (RSI = jump height / ground contact time).
Question 6: During a movement screen, an athlete cannot perform a deep overhead squat without the heels rising. Which mobility restriction should the practitioner assess first?
- Ankle dorsiflexion range of motion (Correct answer)
- Hip external rotation
- Thoracic spine extension
- Shoulder flexion
Correct answer: Ankle dorsiflexion range of motion
Limited ankle dorsiflexion is the most common cause of heel rise during an overhead squat and should be assessed first.
Question 7: What does a high intraclass correlation coefficient (ICC) value (≥0.90) indicate when evaluating a performance assessment?
- Excellent test-retest reliability (Correct answer)
- High criterion validity
- Strong concurrent validity
- Good construct validity
Correct answer: Excellent test-retest reliability
An ICC ≥ 0.90 indicates excellent consistency when the same test is repeated under identical conditions, confirming strong test-retest reliability.
