"I know these classes would improve my stamina, but I'm sure I won't be able to do the movements," says a new participant. Which approach most directly develops the confidence she is missing?
Correct answer: B - Rehearse an achievable movement and give specific feedback on her success.
Recovery nutrition must address both depleted muscle glycogen and muscle-tissue repair. Which nutrient pairing most directly supports these two tasks, respectively?
Correct answer: C - Carbohydrate for glycogen replenishment; protein for tissue repair.
An instructor asks participants to take three seconds to lower from standing into a squat. During this descent, which muscle action provides the principal braking force against knee flexion?
Correct answer: A - The quadriceps acting eccentrically.
A regular indoor-cycling participant takes a prescribed beta blocker. Her clinician has approved moderate exercise on her current medication. During a steady ride, she can talk comfortably but cannot sing and has no unusual symptoms. Her pulse is below the training zone estimated by her watch. What should guide the instructor's response?
Correct answer: D - Maintain the present effort, using her exercise advice and the talk test.
In chest-deep water, participants perform comfortable horizontal arm sweeps while keeping their feet on the pool floor. The instructor wants to increase resistance to the arm movement without adding jumps. Which change uses water drag to accomplish this?
Correct answer: A - Press broad palms through the water at a faster, controlled speed.
During a lateral-raise hold, a participant fatigues before the interval ends. The instructor wants to reduce the dumbbells' torque at the shoulders without changing their mass or lowering the upper arms. Which cue achieves that mechanical change?
Correct answer: C - Bend your elbows so the dumbbells move closer to your shoulders.
A dance class has learned a 16-count foot pattern. When the instructor adds arm movements and a half-turn together, several participants lose the lead foot and fall behind. They can see and hear the instructor clearly. The most useful first adjustment is to:
Correct answer: A - Restore the foot pattern, then introduce one optional layer at a time.
A circuit class has a 32-minute conditioning block. The instructor needs 3 minutes to review station technique, then plans three rounds of eight stations. Each station uses 45 seconds of work and 15 seconds to move or reset. A 2-minute recovery follows each of the first two rounds, but not the third. Which time budget is accurate?
Correct answer: B - The plan takes 31 minutes, leaving 1 minute within the block.
A 74-year-old brings a clinician's Timed Up and Go result of 14.6 seconds. The test involved rising from an armchair, walking 3 meters at his usual pace, turning, returning, and sitting. He walks independently and reports no new symptoms. Under CDC STEADI guidance, how should this finding influence class planning?
Correct answer: A - Recognize increased fall risk and offer balance tasks with stable hand support.
A participant collapses during class and remains unresponsive with occasional gasps. Another staff member has called 911, and the instructor has started CPR. The AED analyzes the rhythm and announces, "No shock advised." The participant is still unresponsive and is not breathing normally. The instructor should now:
Correct answer: D - Resume CPR immediately, beginning with chest compressions.
