Question

1. What are some ways your body regulates the increase of body temperature that also occurs when exercising? Do you think your internal body temperature responded in the same way as your external skin body temperature? Explain.

Answer 1

Ams :

Physical work and exercise in the heat cause early exhaustion and heat-related illnesses compared with cooler conditions, and the incidence of the disorders is associated with intensity of activity and ambient conditions. Thermoregulatory function is critical during working in the heat, which is affected by individual somatotype, fitness level, and physiological status. Exercise-induced decrease in plasma volume (PV) and elevation in plasma osmolality attenuate heat dissipative responses, skin blood flow, and sweating responses to an increased core temperature during exercise in a hot environment; furthermore, these responses are exacerbated with thermal dehydration. Aerobic exercise training as well as thermal acclimation improves thermoregulatory responses which is associated with exercise-induced increase in PV.

Thermoregulatory responses are reduced with biological aging, which would be also improved after exercise training accompanied with an improved maximal oxygen consumption rate, although the improvement is limited in elderly persons relative to young counterparts. Post-exercise protein and carbohydrate intake during training period accelerates exercise training-induced PV expansion and therefore thermoregulatory adaptations both in young and elderly persons

2. Much like a thermostat regulates the temperature inside your home, the hypothalamus regulates your body temperature, responding to internal and external stimuli and making adjustments to keep the body within one or two degrees of 98.6 degrees.

The human body reacts to external and internal changes. Body temperature rises when the external temperature increases but also when the internal temperature increases. Hot outside temperatures, intense physical activity, illnesses that cause fever, and certain medications can all cause a high body temperature.
