What is the main objective of short interval training?

The primary objective of short interval training is to maintain a higher intensity with shorter rest periods. This training method emphasizes performing exercises at maximum effort or intensity for brief periods, followed by shorter recovery intervals. The structure of short interval training encourages improvements in anaerobic capacity, speed, and power while also boosting overall cardiovascular fitness.

By pushing the body to work harder during the activity phases and then allowing only short recovery times, athletes can train their bodies to perform at high intensities for extended durations, effectively enhancing performance in sports that require bursts of speed and power. This method contrasts with approaches that focus purely on endurance or flexibility, which do not emphasize the combination of high intensity and minimal rest that is characteristic of short interval training.
