Environmental Exercise Physiology (fill in blanks) Flashcards
heat transfers through physical contact is what?
conduction
Heat we produce warms the air close to the body, airflow moves this warmed air away is what?
convection
Greatest source of heat loss at rest is what?
Radiation
Greatest source of heat loss when active is what?
Evaporation
Water content in the air is what?
humidity
Central thermoreceptors are located in the __________ and measures temperature of the blood
anterior hypothalamus
______ thermoreceptors are located on the skin and measure temperature around you
Peripheral
______ sweat glands sweat for evaporation and innervated by nerves
eccrine
If core temperature rises, more blood is redirected near skin for cooling
redistribution of blood
In relation to a physiologic response in the energy systems - demand for _____ increases (when it should not normally be needed)
glycogen
______ has less electrolyte lost in it as Na/K is reabsorbed when passing through duct slowly
light sweating
______ is typically less serious. Mineral losses and dehydration. More of one electrolyte (Na) lost over the other (K) can lead to cramping
heat cramps
______ is after cramps (but not always). Excessive fluid loss and may cause dizziness
heat exhaustion
____ is most serious. High core temperature, dry skin, rapid pulse and may lose consciousness
heat stroke
