ACSM Safety and Injury Prevention 2 — Questions and Answers
Question 1: Which environmental condition poses the greatest risk for heat stroke during outdoor exercise?
- Low humidity and high temperature
- High humidity and high temperature (Correct answer)
- High altitude and low temperature
- Low barometric pressure and high wind
Correct answer: High humidity and high temperature
High humidity impairs evaporative cooling, and combined with high temperature it greatly elevates heat stroke risk.
Question 2: A participant reports sharp knee pain during a lunge exercise. The FIRST action an ACSM-certified professional should take is to:
- Apply ice immediately
- Stop the exercise and assess the situation (Correct answer)
- Modify the exercise to a shallower range of motion
- Recommend the participant see a physician next week
Correct answer: Stop the exercise and assess the situation
Immediately stopping the exercise and assessing the situation prevents further injury before any other intervention.
Question 3: What is the recommended minimum clearance time between intense exercise sessions for the same muscle group to prevent overuse injury?
- 12 hours
- 24 hours
- 48 hours (Correct answer)
- 72 hours
Correct answer: 48 hours
ACSM recommends at least 48 hours of rest between intense resistance training sessions for the same muscle group.
Question 4: The Borg Rating of Perceived Exertion (RPE) scale is used in exercise safety to:
- Measure oxygen consumption directly
- Monitor subjective exercise intensity to avoid overexertion (Correct answer)
- Calculate caloric expenditure
- Assess post-exercise recovery heart rate
Correct answer: Monitor subjective exercise intensity to avoid overexertion
RPE allows individuals to self-monitor exercise intensity, helping prevent overexertion and related injuries.
Question 5: Which condition should prompt IMMEDIATE termination of an exercise session?
- Rating of perceived exertion of 14 on the Borg scale
- Mild shortness of breath during aerobic exercise
- Chest pain or pressure during activity (Correct answer)
- Heart rate reaching 75% of age-predicted maximum
Correct answer: Chest pain or pressure during activity
Chest pain or pressure during exercise is an absolute indication to stop activity immediately as it may signal a cardiac event.
Question 6: To reduce the risk of low back injury during resistance training, which technique is MOST important?
- Holding the breath throughout each repetition
- Maintaining a neutral spine position (Correct answer)
- Using maximum possible loads to build strength faster
- Hyperextending the lumbar spine during pulling movements
Correct answer: Maintaining a neutral spine position
Maintaining a neutral spine distributes forces evenly across vertebral structures and minimizes injury risk.
Question 7: Which of the following is a PRIMARY purpose of the warm-up phase in preventing exercise-related injuries?
- Maximizing caloric burn before the workout
- Gradually increasing muscle temperature and blood flow (Correct answer)
- Achieving target heart rate as quickly as possible
- Stretching muscles to their maximum length
Correct answer: Gradually increasing muscle temperature and blood flow
Warm-up gradually increases muscle temperature and circulation, improving tissue elasticity and reducing injury risk.
