Crossfit Safety, Injury Prevention & Scaling 3 — Questions and Answers
Question 1: Which of the following best describes the CrossFit approach to scaling for athletes with different fitness levels in the same class?
- All athletes must perform identical movements at reduced loads
- Each athlete works toward the intended stimulus using appropriate loads and modifications (Correct answer)
- Advanced athletes lead beginners through the workout
- Scaling is only permitted for athletes with documented injuries
Correct answer: Each athlete works toward the intended stimulus using appropriate loads and modifications
CrossFit scaling preserves the workout's intended stimulus by adjusting variables so each athlete achieves a similar physiological response.
Question 2: A trainer observes an athlete hyperextending the lumbar spine at the top of a kettlebell swing. What immediate cue is most appropriate?
- 'Squeeze your glutes and brace your core at the top' (Correct answer)
- 'Swing higher to build momentum'
- 'Widen your stance for better balance'
- 'Lower the weight immediately and stop'
Correct answer: 'Squeeze your glutes and brace your core at the top'
Cueing glute contraction and core bracing at the top of the swing encourages a neutral spine and prevents lumbar hyperextension.
Question 3: When programming a workout for a postpartum athlete who is 6 weeks post-delivery, which movement should a trainer be MOST cautious about?
- Rowing
- Heavy sit-ups and high-rep jumping (Correct answer)
- Dumbbell curls
- Slow walking lunges
Correct answer: Heavy sit-ups and high-rep jumping
Heavy sit-ups and high-rep jumping increase intra-abdominal pressure and impact, which can stress healing pelvic floor and abdominal tissues postpartum.
Question 4: What does 'Rx' mean in the context of a CrossFit workout?
- The workout is a recovery session
- The prescribed load and movements as written (Correct answer)
- The recommended scaling option for beginners
- A medical prescription from a physician
Correct answer: The prescribed load and movements as written
Rx indicates that the athlete completed the workout exactly as prescribed, with all movements and weights as written.
Question 5: An athlete completes a workout but feels dizzy and nauseous immediately afterward. What is the trainer's FIRST action?
- Tell the athlete to lie down and elevate their legs (Correct answer)
- Offer the athlete a protein shake
- Continue timing in case the athlete wants to finish
- Encourage the athlete to walk it off
Correct answer: Tell the athlete to lie down and elevate their legs
Having the athlete lie down with legs elevated promotes blood return to the brain and addresses potential vasovagal or hypotensive symptoms.
Question 6: Which scaling strategy is most appropriate for an athlete who has a shoulder impingement and cannot perform overhead pressing?
- Substitute overhead press with push-ups or dumbbell press at a lower angle (Correct answer)
- Have the athlete rest during overhead portions of the workout
- Increase load on lower-body movements to compensate
- Have the athlete perform the movement with lighter weight overhead
Correct answer: Substitute overhead press with push-ups or dumbbell press at a lower angle
Pushing at a lower angle reduces shoulder impingement stress while maintaining the pushing stimulus appropriate for the athlete's condition.
Question 7: What is the PRIMARY reason CrossFit recommends athletes learn movements with a PVC pipe before adding load?
- PVC pipes are cheaper than barbells
- To build movement patterns safely before adding external load (Correct answer)
- PVC pipes challenge grip strength effectively
- To save barbell equipment wear and tear
Correct answer: To build movement patterns safely before adding external load
PVC pipe allows athletes to practice correct motor patterns without load stress, building the neural pathways needed for safe, loaded movement.
