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:
BMI = Weight (kg) / squared height (in meters)
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.
