CAT Aerobics Trainer Safety & Injury Prevention 4

Question 1

Which musculoskeletal structure is MOST commonly injured during step aerobics?

Accepted Answer

Patellofemoral joint (kneecap)

Answer

The patellofemoral joint experiences high compressive forces during step-up and step-down movements, making it the most commonly injured structure in step aerobics.

Question 2

A certified aerobics trainer notices a participant's low back excessively arches during abdominal exercises. What corrective cue is MOST appropriate?

Accepted Answer

Cue the participant to perform a posterior pelvic tilt and engage the transverse abdominis

Answer

A posterior pelvic tilt combined with transverse abdominis engagement neutralizes lumbar hyperextension, protecting the spine during abdominal exercises.

Question 3

What is the maximum recommended step height for a beginner participant in step aerobics?

Accepted Answer

4 inches (10 cm)

Answer

A 4-inch step height is the standard starting point for beginners, minimizing joint stress while allowing participants to learn proper mechanics.

Question 4

Which of the following is a PRIMARY risk factor for rhabdomyolysis in an aerobics class setting?

Accepted Answer

Sudden introduction of very high-intensity exercise in an unconditioned participant

Answer

Rhabdomyolysis is triggered by excessive muscle breakdown, most commonly when unconditioned individuals perform extremely intense exercise without adequate progression.

Question 5

When instructing participants to perform jumping jacks, which alignment cue BEST prevents knee valgus (knee cave)?

Accepted Answer

Keep knees tracking over the second and third toes upon landing

Answer

Cueing knees to track over the second and third toes ensures proper tibial alignment and prevents medial collapse of the knee joint.
