1. during hiit training, the heart rate: (0.5 points) *

increases
decreases
remains the same

Explanation:

1. The back - and - forth between explosive activity and rest allows the muscle to relax and recover. Muscles need rest periods to repair and grow.
2. Steady cardio activity involves continuous, rhythmic movement that elevates the heart rate for an extended period. Jogging for half an hour is a typical steady - state cardio exercise. Bench presses are strength - training exercises and stretching is for flexibility.
3. High - Intensity Interval Training (HIIT) involves short bursts of intense exercise followed by brief recovery periods. During the intense exercise phases, the heart rate increases to meet the body's increased oxygen demands.

Answer:

1. relax and rest
2. jogging for a half hour
3. increases
