NSCA CSCS Health & Safety 4 — Questions and Answers
Question 1: A strength coach is programming return-to-sport activities for an athlete recovering from a hamstring strain. Which criterion is the MOST reliable indicator of readiness to return to full-speed sprinting?
- Absence of pain at rest for 72 hours
- Full passive range of motion equal to the uninjured side
- Hamstring-to-quadriceps strength ratio ≥60% and symmetry index ≥90% (Correct answer)
- Completion of a 2-week graduated running program regardless of strength measures
Correct answer: Hamstring-to-quadriceps strength ratio ≥60% and symmetry index ≥90%
Objective strength symmetry (LSI ≥90%) and an adequate hamstring-to-quadriceps ratio are the evidence-based functional criteria for safe return to high-speed sprinting after hamstring strain.
Question 2: What is the PRIMARY purpose of a strength training facility emergency action plan (EAP)?
- To document equipment maintenance schedules and vendor contacts
- To ensure rapid and coordinated response to life-threatening emergencies (Correct answer)
- To outline staff scheduling and coverage responsibilities
- To satisfy insurance liability requirements
Correct answer: To ensure rapid and coordinated response to life-threatening emergencies
An EAP establishes pre-planned roles, communication protocols, and procedures so staff can respond rapidly and effectively to medical emergencies, minimizing morbidity and mortality.
Question 3: Which of the following most accurately describes rhabdomyolysis in the context of strength and conditioning?
- Muscle soreness caused by eccentric loading that resolves within 48–72 hours
- Breakdown of muscle tissue releasing myoglobin into the bloodstream, which can cause kidney failure (Correct answer)
- A stress fracture of the long bones caused by repetitive impact loading
- Inflammation of the muscle fascia resulting in compartment syndrome
Correct answer: Breakdown of muscle tissue releasing myoglobin into the bloodstream, which can cause kidney failure
Rhabdomyolysis involves massive muscle cell breakdown that releases myoglobin into circulation; myoglobin can precipitate in renal tubules causing acute kidney injury and is a medical emergency.
Question 4: During a heavy squat session, an athlete suddenly reports severe lower back pain radiating down one leg. The strength coach's MOST appropriate response is to:
- Have the athlete perform McKenzie extension exercises to reduce disc pressure
- Immediately stop the activity and refer the athlete to a physician or athletic trainer (Correct answer)
- Apply heat to the lumbar spine and allow the athlete to continue with reduced load
- Assess lumbar ROM and proceed if the athlete can touch their toes
Correct answer: Immediately stop the activity and refer the athlete to a physician or athletic trainer
Radicular pain (pain radiating down the leg) suggests possible nerve root involvement requiring medical evaluation; coaches are not qualified to diagnose or treat this condition.
Question 5: Which of the following best describes appropriate supervision ratios for a general university strength and conditioning facility according to NSCA guidelines?
- 1 coach to 10 athletes maximum
- 1 coach to 15 athletes for general fitness, 1 to 10 for Olympic lifting areas (Correct answer)
- 1 coach per 30 athletes is acceptable with proper equipment layout
- No specific ratio is required if all athletes are experienced
Correct answer: 1 coach to 15 athletes for general fitness, 1 to 10 for Olympic lifting areas
NSCA recommends 1:15 for general resistance training areas and a stricter 1:10 ratio in areas with Olympic lifting due to the technical complexity and higher injury risk.
Question 6: An athlete is performing Olympic lifts and drops the barbell unexpectedly. Which flooring material BEST protects both the athlete and the structural floor?
- Hardwood flooring with rubber edge matting
- Vinyl tile over concrete subfloor
- Horse stall mats (3/4-inch rubber) over concrete
- Platform-grade plywood topped with 1-inch rubber shock pads (Correct answer)
Correct answer: Platform-grade plywood topped with 1-inch rubber shock pads
Weightlifting platforms constructed of plywood topped with rubber shock-absorbing pads are specifically designed to absorb dropped barbell impact forces, protecting both the floor and the barbell.
Question 7: In the context of NSCA facility risk management, which of the following BEST describes the legal concept of 'assumption of risk'?
- The athlete accepts ALL injuries including those caused by coach negligence
- The athlete voluntarily acknowledges and accepts inherent risks of the activity but not negligent conduct (Correct answer)
- The coach assumes responsibility for any injury that occurs during supervised training
- The facility assumes full liability for equipment malfunction regardless of maintenance records
Correct answer: The athlete voluntarily acknowledges and accepts inherent risks of the activity but not negligent conduct
Assumption of risk means athletes accept the inherent risks of sport/exercise, but this doctrine does NOT protect coaches or facilities from liability for negligent acts or omissions.
