A gym member collapses and is unresponsive with no normal breathing. Which piece of facility equipment can analyze heart rhythm and deliver a shock if needed?
Answer: Automated external defibrillator (AED)
An AED detects shockable rhythms such as ventricular fibrillation and delivers a shock to restore a normal rhythm.
Research suggests setting a treadmill to what incline to better match the energy cost of outdoor running?
Answer: 1%
A 1% grade makes up for the lack of air resistance on a treadmill at typical running speeds.
On an air-resistance rowing ergometer, what does adjusting the damper setting change?
Answer: How much air flows into the flywheel housing, which changes the drag factor
The damper controls airflow to the flywheel, so higher settings feel heavier, like a slower boat.
Blood flow restriction (BFR) training cuffs let athletes gain strength and muscle mass using loads of roughly:
Answer: 20–30% of 1RM
BFR partly restricts venous return, so very light loads can still trigger muscle growth.
A fingertip pulse oximeter used during altitude training measures:
Answer: Blood oxygen saturation (SpO2) and pulse rate
Pulse oximeters use light absorption to estimate the percentage of hemoglobin carrying oxygen.
Most consumer 'smart scales' estimate body fat percentage using:
Answer: Bioelectrical impedance through the feet
Smart scales send a small current through foot electrodes and estimate body fat from impedance.
A coach wants an athlete to keep a steady running cadence of 170 steps per minute. Which simple tool gives a rhythmic audio cue for this?
Answer: A metronome app
A metronome beeps at a set tempo so the athlete can match footstrikes to the beat.
