How should the heart rate feel by the end of the cool-down after interval training?

1. Much lower than pre-exercise level

2. Somewhat higher than pre-exercise level

3. At the pre-exercise level

4. The cool-down does not affect heart rate

The correct answer is: At the pre-exercise level

After interval training, the heart rate should gradually decrease back to the pre-exercise level during the cool-down period. Option A is incorrect because a significant decrease in heart rate could indicate overexertion or a lack of proper cool-down. Option B is incorrect because a slightly elevated heart rate during the cool-down period is normal due to the body's increased demand for oxygen and blood flow after intense exercise. Option D is incorrect because the cool-down period is specifically designed to help the body return to its pre-exercise state, including heart rate. Therefore, option C is the correct answer as the heart rate should be back at the pre-exercise level by the end of the cool-down.
