Effects of Combined Interventions to Optimize Recovery During High-intensity Exercises in Healthy Adults
30. juni 2021 opdateret af: Swiss Federal Institute of Technology
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.

Intervention / Behandling |
|---|---|
|
Eksperimentel: ERP Intervention
Combination of different methods to improve recovery.
|
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 |

Placebo komparator: Placebo
A combination of methods similar to the ERP intervention but at an intensity / mixture supposed to be ineffective at improving recovery.
|
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 |

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Change in mean power output
Tidsramme: 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.
|
through study completion, an expected average of 3 weeks per participant
|
|
Change in fatigue index
Tidsramme: 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.
