HOW MUCH IS IMPORTANT THE THERMOREGULATION DURING SPORT?

17/04/2019

When you do any type of physical activity, it’s not just your muscles that are involved: your baseline temperature changes too, as your body produces more heat. In fact, from 1 – 1.5 kcal a minute, you burn 6-7 and up to 15-20 kcal a minute, depending on the type of sport.
In addition to the warmth produced by the body the external temperature is also a very important factor, conditioning the athlete’s physical condition and performance. As ambient temperature increases, evaporation becomes more important in order to keep body temperature constant, and above 18°C becomes the main mechanism for dissipating heat from physical exertion, any contact with hot surfaces or sunlight. Under opposite conditions, on the other hand, such as a temperature of around 10°C, the body disperses heat without evaporation.
Thermoregulation is essential for sports performance, since when the body perspires both blood flow to the muscles and oxygen consumption decrease.
