bodybuilding

(bod′ē-bild″ing) The use of resistance training and weight training along with nutritional and/or pharmacological methods to increase muscle size in an effort to alter physical appearance.

body burden

The amount of a substance present in an organism. The term is usually reserved for descriptions of infectious or toxic substances. It may be represented arithmetically as the concentration of the substance multiplied by the mass of the tissues that store it.

body composition

The relative percentages of bony minerals, cell mass, lean body mass, body fat, and body water in an organism, and their distribution through the body. Determination of the specific gravity of the body is done to estimate the percentage of fat. This may be calculated by various methods, including underwater weighing, which determines the density of the individual; use of radioactive potassium, 40K; measuring the total body water by dilution of tritium; and use of various anthropometric measurements such as height, weight, and skin fold thickness at various sites.

None of these methods is free of the potential for error. Underwater weighing is useful but may provide misleading information when used in analyzing body composition of highly trained athletes. The obese person has a lower body density than does the lean person because the specific gravity of fat tissue is less than that of muscle tissue. The fat content for young men will vary from about 5% to 27% and for women from about 18% to 35%.

Bone mineral density is measured to determine the potential fragility of bones to fracture, i.e., to determine the presence of either osteopenia or osteoporosis.

body contouring

Any form of cosmetic surgery used to shape, sculpt, or reshape body lines. It includes "lifts," e.g., face-lift, and abdominoplasty.

body dysmorphic disorder

ABBR: BDD. A preoccupation with one or more imagined defects in appearance. The disorder is also known colloquially as athletica nervosa. SEE: muscle dysmorphia.

body image, disturbed

Disruption in the way one perceives one's body image, e.g., after an injury or illness, or an incongruity between one's actual appearance and the way one perceives it, e.g., in anorexia nervosa. SEE: body dysmorphic disorder; Nursing Diagnoses Appendix.

body jewelry

Any adornment placed through and attached to a body part, e.g., belly or nipple rings, nose studs, or tongue bars.
