What is the storage of heat equation?
metabolism- work done - heat loss (radiative+ conductive+ evaporative)
whats the most important method of regulating core temp during exercise?
evaporating of sweat off the skin
What is the rate of heat loss equation? (for radiation)
Rate of heat loss= Radiative heat transfer X (mean skin temp-radiant temp of object/enviorment) X body surface area
What is the rate of heat loss equation for convection?
Rate of heat loss= convective heat transfer coefficient X (mean skin temp- ambient temp) X body surface area
what is the rate of heat loss equation for evaporation?
Rate of heat loss= evaporative transfer coefficient X (water vapor pressure of skin- water vapor pressure of environment) X body surface area
what brain center controls temp?
hypothalamus
which has a larger temp range, warm or cold receptors?
cold receptors
At hotter temps how does blood to heart change?
at hotter temps, there is LESS blood to perfuse the heart

this lowers SV, and increases HR (relative to cold)
how does glycogen usage change in heat?
in hot, glycogen gets burned much faster
