How can interval training be used to improve both aerobic and anaerobic power?

Step 1 of 2

Interval training is a type of exercise training which involves the performance of repeated bouts of exercise with brief pause or recovery periods in between. Depending on the type of training involved, the duration of intervals are decided. There exist two types of intervals in an interval training program; work interval and rest interval.

The work interval is the duration of performing an exercise task, whereas the rest interval is the duration of the pause or rest in between the work intervals. The duration of work interval depends on the intensity of load and length of the performance. The rest interval also depends on the type of metabolism that supplies energy during the exercise bout.
