Physiological response to heat stress
Webb1 aug. 2024 · Many physiological responses to heat stress are strategies aimed at maintaining core body temperature ( Collier et al., 1982 ). In periods of heat stress, the amount of heat production and heat accumulation leads to an inability to effectively dissipate the heat gained. Physiologic control of heat stress relies on the principles of heat balance discussed above and the integration of a neurologic autonomic control. This control, like many physiologic systems, can be divided into afferent and efferent responses, the former acting as a sensor and the latter acting as a regulator of the … Visa mer Skeletal muscle metabolism yields two products, locomotion and heat. The amount of heat generated is directly proportional to the intensity of exercise with net heat gain being calculated by accounting for work … Visa mer Radiation is characterized as heat exchange in the form of electromagnetic waves between objects of different temperatures. Mean radiant temperature for the human body is dependent on the temperature of … Visa mer Convective means of heating or cooling are the most intuitive aspects of human heat balance. For the purposes of human thermoregulation, we … Visa mer Conduction, as the direct transfer of heat through two solid objects in contact, generally plays a negligible role in exercise thermoregulation [11]. However, it should be noted that some … Visa mer
