The scientific world promises that acclimatise to high temperatures improves resistance, strength and speed. This is what detected by study of Racinais et al. (2015): athletes who acclimatize the blood volume of the blood and lower the heart rate; Hence, a greater muscle oxygenation and better sprint performance and strength. Heat Training, it must be said, is not for all levels. It requires a lot of care and attention. It is essential to start with short sessions, preferably early in the morning or late afternoon, and gradually increase the intensity. The hydration first, during and after training is crucial to avoid dehydration, heat strokes and pressure drops. In the first days do not aim for performance, but to adaptation and always listen to the signals of the body.
