Thermoregulation and Sodium Conservation Index (TSCI)

BeOne allows you to build different measurement indicators and performance monitoring. The Thermoregulation and Sodium Conservation Index (TSCI) is an absolute measure that makes it possible to evaluate the physiological impact of exercise on the thermoregulation mechanism. Sodium is a particular electrolyte absolutely fundamental to the functioning of the body. In order to conserve sodium, there are different physiological mechanisms that allow the body to maintain a stable concentration in the blood. During training, sweating helps regulate internal temperature but it causes sodium losses. When you repeat a workout regularly, the body adapts to minimize sodium losses in sweat, allowing for more effective and longer-lasting temperature regulation. This mechanism is implemented from the first day of training. Day after day, training creates physiological stress, triggering the mechanism of adaptation to exercise. Thus, for a given effort, the loss of sodium compared to skin temperature is a direct and reliable index of an athlete's training level. The progression of this index over time thus makes it possible to measure the body's adaptation to exercise and therefore the effectiveness of training. It is also useful to avoid overtraining: when the index no longer progresses, the body has reached its maximum threshold, knowing this threshold allows overtraining to be avoided! Here is an example of a graph representing the progression of the performance of an athlete on 13 cycling sessions over 20 weeks. We also see that it is also possible to give a clear value of his total progress: here the athlete progresses by 53% over 20 weeks, that is to say that at the physiological level for one hour of cycling at 100 watts indoors his body consumes 53% less sodium (he could therefore exercise 53% longer for the same physiological stress).
