Muscle activation and heart rate responses to a side‐step interval exercise

The side‐step test is commonly used to assess agility. Side‐step interval exercise may also be a potential way to improve cardiorespiratory and muscular fitness. However, the acute heart rate and muscle activation response to this type of exercise is not well established. In addition, different tempos can influence these responses. The purpose of this study was to determine the acute heart rate and muscle activation responses of a side‐step interval exercise to different exercise tempos.
