Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* 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.
