Question 4 of 5 What does interval training do for an athlete? A. It makes muscles stronger so they can exert more force. B. It lengthens the amount of time the athlete can intensely exercise. C. It can greatly improve finish times in races and competitions. D. All of the above.

## Step 1<br />Interval training is a type of training that involves alternating periods of high-intensity exercise with periods of lower-intensity recovery or rest. This type of training is commonly used by athletes to improve their overall fitness and performance.<br /><br />## Step 2<br />Option A suggests that interval training makes muscles stronger so they can exert more force. This is true because the high-intensity periods of interval training require the muscles to work harder, which can lead to increased strength and muscle mass.<br /><br />## Step 3<br />Option B suggests that interval training lengthens the amount of time an athlete can intensely exercise. This is also true because the recovery periods in interval training allow the athlete to rest and recover, which can help them maintain a high level of intensity for longer periods.<br /><br />## Step 4<br />Option C suggests that interval training can greatly improve finish times in races and competitions. This is true because the high-intensity periods of interval training can help athletes build up their speed and endurance, which can be beneficial in races and competitions.<br /><br />## Step 5<br />Given that all the options A, B, and C are correct, option D, which states "All of the above", is the correct answer.
