简要总结
The goal of this clinical trial is to compare the efficiency of water biking training in hot (35°C) versus neutral (25°C) temperature water to elicite heat acclimation in healthy recreative athletes.
详细描述
The goal of this clinical trial is to compare the efficiency of water biking training in hot (35°C) versus neutral (25°C) temperature water to elicite heat acclimation in healthy recreative athletes. The main questions it aims to answer are:
- Does the water biking training protocol in hot versus neutral temperature water improve the time trial in an artificially hot and humid indoor environment?
- Does the water biking training protocol in hot versus neutral temperature water improve the VO2 max performance and force/velocity profile in neutral indoor environment?
- What are the main acclimation adaptations (central and cutaneous temperature), heart rate, cardiac function, sweating quality, sleep quality, haematologic profile.
Participants will have to do pre and post training tests in both normal environment (cardiorespiratory stress test, force/velocity profile test, echocardiography) and artificially hot and humid indoor environment (time trial). The training protocols consists in 10 sessions of 1 hour of water bike aerobic training (5 times a week for 2 weeks) at an intensity based on the heart rate corresponding to the 1st respiratory threshold, in hot (interventional group IG: 35°C) versus neutral (control group CG: 25°C) water.

结局指标
主要结局
Change of the distance traveled (meter) on a Time Trial between pre and post training tests in hot and humid atmosphere (environmental room)
时间窗: The 1st Time Trial will be performed the week preceding the program training. The 2nd Time Trial will be performed the week following the program training
The participant has to perform the longer distance possible in 30 min on a stationary bike in hot and humid atmosphere (environmental room). The change of distance (measured in meter) will be assessed before and after the 2 weeks training program.
次要结局
- Change in VO2 Max (ml/kg/min) between pre and post training tests in normal environment(The 1st maximal cardiorespiratory test will be performed the week preceding the program training. The 2nd maximal cardiorespiratory test will be performed the week following the program training)
- Change in Maximal Aerobic Power (Watts) between pre and post training tests in normal environment(The 1st maximal cardiorespiratory test will be performed the week preceding the program training. The 2nd maximal cardiorespiratory test will be performed the week following the program training)
- Change of Sleep quality between the first and the last training session of water biking(The sleep self-questionnaire will be performed immediately after the first training session (Day 1) and immediately after the last training session (Day 10) of water biking)
- Change of "global longitudinal strain of left ventricule" (%) measured during an echocardiography between pre and post training tests in normal environment(The 1st echocardiography will be performed the week preceding the program training. The 2nd echocardiography will be performed the week following the program training)
- Change on central temperature (°C) between pre and post training test in hot and humid atmosphere (environmental room)(The 1st Time Trial will be performed the week preceding the program training. The 2nd Time Trial will be performed the week following the program training)
- Change of Na concentration (mmol/L) in the sweat between pre and post training test in hot and humid atmosphere (environmental room)(The 1st Time Trial will be performed the week preceding the program training. The 2nd Time Trial will be performed the week following the program training)
- Change on cutaneours temperature (°C) between pre and post training test in hot and humid atmosphere (environmental room)(The 1st Time Trial will be performed the week preceding the program training. The 2nd Time Trial will be performed the week following the program training)
