What is Body Composition?
Body composition refers to the relative amounts of water, protein, minerals and fat in the human body of the science of determining the absolute and relative contributions of these specific components. We study it because it is a good indicator of health and fitness. High % body fat is associated with an increased risk of developing health problems such as heart disease, diabetes, hypertension, cancer and hyperlipidemia. We can avoid all these conditions and increase longevity with appropriate body fat levels.
Essential & Storage Fat
Essential fat is stored in the bone marrow, muscles, spleen, heart, lungs, intestines, liver and kidneys. It is needed for normal physiological functioning of the body. This is about 3% for men and 12% for women.
Storage fat is the fat accumulated in adipose tissue. It functions as insulation, protection against trauma, and can be used as an energy substrate. Men store fat around the waist while women store it around the hips and thighs.
