Exam 13: Body Composition Assessment

Competitive __________ generally have higher body fat levels than distance runners, probably from self-selection related to economically exercising in the different environments rather than real metabolic effects caused by the environments.

At a given BMI level, Asians have greater body fat content than Caucasians and thus show greater disease risks related to adipose levels.

The rationale for using skinfolds to estimate body fat comes from the relationships among all of the following factors except __________.

Approximately 12% body fat in the average young adult male

Body weight measured in the air minus body weight in water with temperature correction for water density.

Which of the following methods to assess body composition involves submersion in water?

The famous military "K rations," compact nutritional packets used by the U.S. military in World War II, was named to honor University of Minnesota physiologist Ancel Keys, the man who invented them.

Most widely accepted clinical tool to assess spinal osteoporosis and related bone disorders.

Bioelectrical impedance analysis measures body composition using principles of light absorption and reflection.

Male body builders generally average __________ body fat based on underwater weighing to assess body composition.

Dual-energy x-ray absorptiometry (DEXA) reliably quantifies fat and nonbone regional lean body mass, and the mineral content of the body's deeper bony structures and muscle mass.

Sheldon, the developer of the somatographic method, believed this technique:

The most common anatomic locations for measuring skinfolds include the triceps, subscapular, suprailiac, abdominal, and upper thigh.

Dividing body mass by body volume.

Fat mass (kg) = body mass (kg) ÷ (percentage fat × 100)

Height-weight tables provide extremely reliable information about body composition.

Refers to a condition in which body fat exceeds an age- or sex-appropriate average by a predetermined amount. In most situations, this condition represents the correct term to assess individual and group body fat levels.

In the human body, the BIA technique reduces resistance or impedance to electrical current flow.

Being above some "average," "ideal," or "desirable" body mass based on weight-for-height tables is a reliable clinical measurement and should be used to set weight loss goals.

Employs principles of light absorption and reflection to assess body composition.
