Body composition analysis is a physical test that measures the proportion of the various components of a person’s body. It helps patients to understand what is going on inside their bodies by categorizing weight into muscle mass, water, and body fat. This knowledge can help patients with weight-related problems make better informed decisions about their behaviour. Also, Its measurement plays an important role in both sports and health.
The most common forms of body composition analysis are the body mass index (BMI), skin fold caliper testing, bioelectrical impedance, and hydrostatic weighing. Among these methods, the most common form of body composition analysis is Body Mass Index (BMI) as it is the most easiest and cheapest. It is often used by fitness centers, doctors, and insurance companies to give a picture of body composition by mathematically comparing height to weight.
BMI is calculated using the following formula:
Body composition is often represented as a two compartment system; lean body weight and fat weight. The fat weight is then expressed as a percentage of total body weight, where percent body fat = (fat weight / total body weight) x 100.
Use of different methods for measuring body composition depends on what needs to be achieved.
