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.

Interventions

Type	Name	Description
OTHER	ERP	The ERP intervention is applied in a randomized and counter-balanced order across visits 2-4 in each 3-min break in-between the six 30-s sprints, with one intervention per visit. The order and timing of the constituents of the interventions will be strictly constant within and between participants. ERP: 1) neck cooling with an iced gel pad, 2) drinking a ∼ 6% CHO solution, 3) mouth-rinsing with a ∼10% CHO, ∼6 mg ･ kg -1 caffeine solution, 4) performing submaximal squats and 5) hyperventilating a hyperoxic mixture
OTHER	Placebo	The control intervention is applied in a randomized and counter-balanced order across visits 2-4 in each 3-min break in-between the six 30-s sprints, with one intervention per visit. The order and timing of the constituents of the interventions will be strictly constant within and between participants. 1\) neck "cooling" with room temperature gel pack, 2) drinking an artificially sweetened solution, 3) mouth-rinsing with artificially sweetened solution (containing no caffeine), 4) performing unloaded squat manoeuvres, 5) deep breaths with room air
