![]() The percentage of body fat can be calculated from overall body density. We know the density of fat, muscle and bone and water. Volume equals your weight on land minus your weight under water. Volume is calculated by measuring how much water your body displaces underwater. Underwater weighing also tries to measure a person's overall density. After exhaling all of the air from your lungs, you pull yourself underwater completely and sit very still for 10 seconds while the scale stabilizes. Subject sits on a scale inside a giant tank of water. Underwater/Hydrostatic WeighingAdvantages: Very accurateĭisadvantages: Difficult to find You get wet during the test We know the density of fat, muscle and bone and water. On the other hand, endurance had no correlation with any of the variables considered. Since the density of an object (in this case your body) equals mass divided by volume, we know mass equals your body weight. The pod measures the volume of air you displace, allowing the Bod Pod to measure your overall density. Subject steps inside an egg shaped "pod" wearing as little clothing as possible. Whole Body Plethysmography (Bod Pod)ĭisadvantages: Difficult to find Hard to pronounce *Special Note: Due to its ability to measure intramuscular fat the DEXA reading will typically be 3 to 8 percent higher body fat than all other methods of measurement. The non-fat part of your body is called lean tissue, which includes your muscle. A small dose of radiation passes through the body allowing X-rays to distinguish fat from muscle from bone. Body composition testing determines how much of your body is and isnt fat. Here is a review of the five most commonly available methods of body composition testing (listed in order of most accurate to least accurate): DEXA ScanĪdvantages: Gold standard accuracy Very repeatableĭisadvantages: Difficult to find Can be expensive Each method has its advantages and disadvantages. There are many different ways to measure body composition. Body fat is a storage form of energy and therefore has a very low calorie demand. The more lean tissue you have, the higher your resting metabolic rate will be. Lean tissue is known as metabolically active tissue, the tissue that burns calories all day. These composition percentages paint a much better. The non-fat part of your body is called lean tissue, which includes your muscle, water, bone and organs. Your body composition tells you how much of your body is made up of fat and how much of it is muscle. In physical fitness, body composition is used to describe the percentages of fat, bone, water, and muscle in human bodies. Learning about your body composition is key to your optimal performance and appearance because it can help you strategize an exercise plan in terms of your need to lose fat, build muscle or both.īody composition testing determines how much of your body is and isn't fat. If you want to run faster, bike longer or see some of that hard-earned muscle show through, you need to understand body composition.
