In training, the term 'interval training' refers to:

Interval training is characterized by alternating periods of high-intensity exercise with lower-intensity recovery periods. This method allows for increased effort during the high-intensity segments, which can lead to improvements in both aerobic and anaerobic fitness. The alternating nature of the training helps in enhancing cardiovascular efficiency and performance while allowing the body to recover during the lower-intensity intervals.

The effectiveness of this training approach lies in its ability to maximize workout intensity and caloric expenditure in a shorter amount of time compared to steady-state workouts. This makes it particularly beneficial for athletes looking to improve speed, endurance, or overall fitness.
