Using Body Composition as a Fitness Indicator FAQs

Yes, body composition can be an indicator of health risks, as high levels of body fat, especially visceral fat, are associated with increased risks of chronic diseases such as heart disease, diabetes, and certain cancers. A healthy body composition, with a balanced ratio of muscle to fat, can reduce these risks. Monitoring body composition can therefore be a valuable tool in preventive health care.
Body composition can be measured using various methods such as bioelectrical impedance analysis (BIA), dual-energy X-ray absorptiometry (DEXA), and skinfold measurements. Each method varies in accuracy, accessibility, and cost, with DEXA providing the most precise results but being more expensive. Knowing the most suitable method for your needs can help in accurately tracking progress.
Exercise, especially strength training and cardiovascular activities, can significantly alter body composition by reducing body fat percentage and increasing lean muscle mass. These changes improve overall fitness, enhance metabolic health, and can shift the body’s energy balance towards using fat as a fuel source.
