The most direct cause of muscle fatigue during any exercise in direct heat is dehydration of the body system as well as excessive build up of lactic acid.
Your urine is hot after exercise because of the internal body heated during the process of working out. Running, jumping, hiking, and lifting weights produces thermogenic heat throughout the body, which transfers to the urine.
The control of blood flow during exercise is more complicated than at first glance. At lower intensity exercise or at the start of exercise one of the main problems is heat. The blood carreis heat from the core to the skin allowing it to escape. During exercise heat would build up to dangerous levels is this system wasnt in place. However after more time the requirement of the muscles for oxygen outweighs the need to remove heat and so the blood flow to the skin is cut preserving more to flow to the the muscles.
i think its the indocrine :/
A datacenter rack is an exothermic system, in that air travelling into it produces a chemical reaction in which the system produces heat. Under conditions of constant pressure, the heat that is released is termed enthalpy (or "heat content").[SOURCE: Schmidt,IBM,2005]
Our glands produce heat, which can cause a fever for us. Thebody systemthat produces the most body heat within us is our sweating system.
The effects of exercise are at many levels since the increased activity requires a parallel increase in the rate of metabolism and produces waste products that must be disposed. In addition the increased activity produces heat that is dissipated at a cost in lost of fluid (blood volume decreases) and salt loss. Finally, there The effects of exercise are at many levels since the increased activity requires a parallel increase in the rate of metabolism and produces waste products that must be disposed. In addition the increased activity produces heat that is dissipated at a cost in lost of fluid (blood volume decreases) and salt loss. Finally, there are neurotransmitters released with exercise: natural endorphins.

The demand for ATP is supported by an increased rate of cellular respiration, but about 60% of the energy from food produces body heat instead of ATP.
