Brief Summary

As part of the preparation at the Paris 2024 Olympic Games, the French rowing and cycling federations and a consortium of researchers met to reach an ultimate goal: to increase the number of medals in these two disciplines for Paris 2024 Olympics.

Study Arms (1)

Track cyclists and rowers (males and females)

EXPERIMENTAL

All female and male rowing and track cycling athletes at the national or international national or international level, registered in a selection process and likely to represent France at the likely to represent France at the 2024 Olympics will be asked to take part to take part in this study.

Other: Hypoxia

Interventions

Hypoxia OTHER

Subjects will be subjected to mild hypoxia simulating an altitude of 1750 m (normobaric hypoxia). Hypoxia decreases oxygen supply to tissue and limit exercise capacity. For this, the subjects will inhale a gas mixture depleted in oxygen (enriched in nitrogen). The barometric pressure at 1500 m being 621 mmHg, PIO2 at this altitude (PIO2 = (621 - 47) x 21%) is 120.5 mmHg. For sea level altitude where the barometric pressure is 760 mmHg, the hypoxic gas mixture should contain (x = 120.5 / (760 - 47)) 16.8% O2. Thus, by inhaling a gas mixture that is oxygen-depleted from 21 to 16.8%, subjects (will simulate the altitude of 1750 and) will experience the equivalent of a 20% reduction in oxygen supply.
