Overview
Brief Summary
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.

Outcomes
Primary Outcomes
Change in mean power output
Time Frame: through study completion, an expected average of 3 weeks per participant
Measured over the six 30s high-intensity cycling sprints in each of the three conditions. Mean power mirrors the body's ability to generate muscle power and physical energy. Any meaningful effects of the recovery interventions will eventually translate into a higher power output.
Change in fatigue index
Time Frame: through study completion, an expected average of 3 weeks per participant
Fatigue index = drop in power output from the beginning to the end a 30s sprint test. The change in this index will be calculated from the 1st to the 6th sprint test in each condition.
