简要总结
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.
详细描述
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:
- the best use of athletes' physical abilities (for race strategy, cycling gear ratio or rowing levers)
- 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.
