Thermoregulation in boys at prepubertal age (7-15 years). 1984

J Laszczyńska, and E Sliwińska

In 70 boys aged 7-8 and 14-15 years the temperature of the skin surface (at rest), rectal temperature, thickness of the skin-fat fold and heat loss by radiation and convection were measured. Then the mean weighted skin temperature (Ts) and body thermoinsulation (I) were calculated. The investigations were carried out stable physical conditions of the environment at the ambient temperature (Ta) of 20 degrees C. It was found that the thermoinsulatory properties of the body increased with age, while the amount of eliminated heat decreased. At the age of 7 to 15 years the value of body thermoinsulation was closely correlated to the thickness of the subcutaneous adipose tissue and significantly lower than the reported values in adult men.

D012885	Skinfold Thickness	The measurement of subcutaneous fat located directly beneath the skin by grasping a fold of skin and subcutaneous fat between the thumb and forefinger and pulling it away from the underlying muscle tissue. The thickness of the double layer of skin and subcutaneous tissue is then read with a caliper. The five most frequently measured sites are the upper arm, below the scapula, above the hip bone, the abdomen, and the thigh. Its application is the determination of relative fatness, of changes in physical conditioning programs, and of the percentage of body fat in desirable body weight.
