Document Summary
3 major structural components of human body: skeleton, muscle, fat, distributions is gender specific, age-related, hereditary, ethnic. Anthropometry measurement of body size and proportions including skinfold thicknesses, circumferences, bony widths and lengths, height, and body weight. Two-component model the amount of fat and fat-free mass of which the body is composed: fat-free mass is primarily composed of bone, muscle, vital organs, and connective tissue. Establish reasonable fatness ranges for athletes in various sports. Accurate measures of body composition are needed to develop sound weight reduction programs. Knowledge of bone mineral content in women and children is important. Monitor changes in body composition associated with disease. Essential fat - fat that is required for normal physiological functioning. Structural components of cell membranes, required for the synthesis of certain hormones, transport of fat-soluble vitamins, etc: storage fat - fat that is stored in adipose tissue for energy supply purposes.
