Many sports such as soccer, basketball, volleyball, tennis, and football involve bouts of high intensity exercise interspaced with periods of light activity or rest. The energy requirements for these athletes are very specific. The body needs to provide energy quickly to perform powerful movements such as short sprints, jumping, and throwing. Between high intensity movements, the body needs to still provide and restore energy that can be used quickly for the next bout of high intensity exercise.
