Sweating is not a side effect. But rather a secondary effect of the body in response to increasing heat / energy expenditure of basal metabolism
The exercise-induced thermogenesis (TIE), also called Thermogenesis by physical activity (TAF), English Exercise activity thermogenesis (EAT), or Exercise-induced thermogenesis (EIT) is a metabolic process, sub-process of thermogenesis. The EAT is the energy expenditure induced increase physical-sports [1] [2]. Sometimes some research call this event as Physical Activity Energy Expenditure (EEAP) or Exercise-induced Energy Expenditure (EIEE), ie energy expenditure of exercise-induced or physical activity, referring specifically to the energy consumption rather than thermogenic event. Together with the consumption of oxygen in excess post-exercise thermogenesis and from non-associated exercise (NEAT), the EAT is the amount of energy expenditure associated with the activity generally took place during the day (EEPA, Energy expenditure to two physical activity), in turn included in the calculation or estimation of the total metabolism (MT) or of the daily caloric expenditure [2].
Physiology
Aerobic exercise generally determines a calorie expenditure directed greater than that of resistance (anaerobic lactic acid). For example, a resistance exercise intense requires an energy expenditure of approximately 66% compared to an aerobic exercise intense equal duration. In this respect, the energy expenditure of aerobic direct induced is greater than that of anaerobic lactic. This is because of oxidative processes that exploit also and especially lipids for energy production in addition to carbohydrates, and representing an energy value more than double compared to the latter (9 kcal / g versus 4 kcal / g). However it does not consider an equally important parameter in assessing the overall energy expenditure caused by physical activity, or EPOC, that consumption of excess oxygen after training. This is in other words the calorie expenditure induced by physical activity in an indirect manner, that is, only later at the end, or, in the case of anaerobic exercise, even in the pauses between sets. Despite caloric expenditure directly induced increase anaerobic endurance is lower, this training method can significantly stimulate energy expenditure, but much more through indirect mechanisms. The indirect effect of the workout anaerobic resistance occurs mainly with the increase in the total metabolism, so oxygen consumption, energy expenditure, thermogenic processes, and the oxidation of fat. In fact, even endurance exercise increases the loss of body fat, intensifying the use of lipids in the post-training [3]. So the EAT is into account only the direct metabolic (evaluating processes thermogenic), while the indirect currency EPOC (evaluating oxygen consumption). Both are needed to identify the total energy expenditure induced by training physical. In this sense, the thermogenic processes induced by training remain even after the term of physical activity, for a time more or less long.
