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
