Effects of Body Composition and Body Dimensionon Body Temperature Regulation during Exercisein Hot and Cool Environments

Body Temperature Regulation in Hot Environments

Organisms in hot environments will not be able to passively dissipate metabolically generated heat. Instead, they have to revert to evaporative cooling, a process that is energetically expensive and promotes excessive water loss. To alleviate these costs, birds in captivity let their body temperature increase, thereby entering a state of hyperthermia. Here we explore the use of hyperthermia in ...

Physiol. 227(3): 583-589. 1974.-The body temperature (Tb) of hibernating golden-mantled ground squirrels, Citellus lateralis, passively follows ambient temperature (Tft) down to some critical temperature below which metabolic heat production increases and the differential between 1‘1, and T:, in...

The effect of back pain on body posture, Somatotype and body composition in women

Background: Low back pain causes movement and occupational restrictions in women. The aim of this study was to compare women with and without low back pain and its relationship with body type, muscle percentage and fat. Methods: The statistical population consisted of women with low back pain (28 people, 30 to 60 years old) were randomly selected and 28 people were selected as healthy or contr...

The regulation of body temperature.

Appetite and the regulation of body composition.

Stability of body composition requires that energy intake equals energy expenditure when integrated over prolonged periods. As recent human studies have failed to demonstrate active changes in energy expenditure with changes in body composition, it is likely that energy intake is continually adjusted to preserve a constant total adipose tissue mass. If adipose tissue mass is regulated directly,...
