A) Define subcutaneous fat, visceral fat, and percent body fat. B) Also identify and describe three methods for assessing body weight and body compositions.

A) - Subcutaneous fat: Fat that accumulates beneath the skin, typically in areas such as the thighs, hips, and abdomen. - Visceral fat: Fat that accumulates around the organs in the abdominal cavity and is associated with an increased risk of diseases such as diabetes, heart disease, and certain cancers. - Percent body fat: The percentage of total body weight that is composed of fat. B) - Body mass index (BMI): A measure of body weight relative to height. It is calculated by dividing weight (in kilograms) by height (in meters) squared. However, BMI does not take into account differences in body composition (muscle mass vs. fat mass) and may not be an accurate indicator of health for individuals with a high level of muscle mass. - Skinfold thickness measurement: A method of estimating body fat by measuring the thickness of folds of skin at different locations on the body using calipers. Although inexpensive and non-invasive, this method is subject to human error and may be less accurate for individuals with a higher level of body fat. - Dual-energy X-ray absorptiometry (DXA): A medical imaging technique that measures bone density, as well as body fat and lean tissue distribution. This method is considered to be one of the most accurate and precise methods for assessing body composition, but is also more expensive and usually requires specialized equipment and expertise.
