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.

Detailed description

The objective of this study is to evaluate the maximum capacity of power production of athletes by describing their power-endurance profile and the physiological factors underlying this maximum power generation capacity. These assessments will guide coaches and athletes for: 1. the best use of athletes' physical abilities (for race strategy, cycling gear ratio or rowing levers) 2. adaptation of training program to improve the maximum capacity of power production of the athletes, in order to increase the number of medals at the Paris Olympics 2024.

Type	Name	Description
OTHER	Hypoxia	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.
