During exercise, the release of energy as heat and When the body temperature is higher than that of its the concomitant rise in body core temperature evoke surroundings, a greater quantity of heat radiates powerful physiological mechanisms to promote heat from the body than to it.
WebDuring exercise, heat is produced mainly from working muscle contractions and core temperature can go above 40 °C (104 °F). How does the body lose heat? As previously discussed, the body regulates temperature like a furnace. It is constantly producing heat and then dispersing it through various processes. WebNormal body temperature is roughly 98.6 °F (37 °C) and is influenced by environmental changes and physical exertion. During exercise, heat is produced from muscles, which causes a rise in body temperature. To manage the increase in body heat, heart rate increases to help deliver blood to the surface of the skin for heat release.
WebWith exercise of longer duration, particularly in a hot and humid environment, progressively more of the car- diac output will be redistributed to the skin to counter the increasing body temperature, thus limiting both the amount going to skeletal muscle and the exercise endurance (Rowell 1986).
