The body composition and physical dimensions of 9- to 12-year-old experienced wrestlers. 1982

S P Sady, and W H Thomson, and M Savage, and M Petratis

Body composition and physical dimensions were compared between 23 young, experienced wrestlers (mean age +/- SE = 11.0 +/- 0.21 yr) and 23 school children (11.2 +/- 0.24 yr). The wrestlers were among the best wrestlers from local wrestling clubs and averaged 2.7 (+/- 0.27) yr of experience. They had won 72% (+/- 1.8%) of the total 75 (+/- 9.1) matches. The comparison group consisted of volunteers from local elementary schools. Standard densitometric and anthropometric techniques were used to measure the body composition and physical dimensions of each group. The wrestlers were 4 kg lighter (P less than 0.05) and had a smaller percent fat than the comparison group (13.3 +/- 0.66% and 20.0 +/- 1.13%, respectively). The weight difference between groups was due to the larger fat weight of the comparison group since lean weight differed by only 0.8 kg. Fat differences were also reflected in the larger skinfolds and "fat" circumferences of the comparison group. No group differences were noted in diameters. It is concluded that compared to other children young experienced wrestlers have similar skeletal structures and lean body weights. The comparison group possessed more body fat.

D000273	Adipose Tissue	Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.

D000886	Anthropometry	The technique that deals with the measurement of the size, weight, and proportions of the human or other primate body.
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.
