About

The objective of the study is to evaluate the effects a complex recovery intervention during the breaks of a repeated sprint test on exercise performance compared to placebo and control conditions. The enhanced recovery package (ERP) includes neck cooling with an iced gel pad, drinking a 6% CHO solution, mouth-rinsing with a 10% CHO, 6 mg･kg -1 caffeine solution, performing submaximal squats and hyperventilating a hyperoxic mixture; all applied in each 3-min break in-between the six 30-s sprints. This intervention will be compared to a placebo and a control condition.
