WebWorking muscle produces heat in two ways: First, the chemical energy is about 20 to 25 per cent efficient in turning into mechanical energy. This excess energy is lost as heat. Second, metabolic reactions, both anaerobic and aerobic, also produce excess heat that your body needs to remove. WebAlthough the production of heat can detract from the efficiency of working muscle, energy that appears as heat is not always wasted. In warm-blooded animals, for example, the heat released by muscles maintains a constant body temperature regardless of the environmental temperature.
