The human body is composed of fat, muscle, bone, and internal organs (among other things). Body composition testing gives us an estimate of what percent of your body is made of fat versus fat-free mass.
Muscular Fitness can be divided into three categories: strength, power, and endurance. Each of these characteristics can affect how well different activities are performed.
Exercise training produces positive changes on a cellular level in the body. Some of these changes affect blood cholesterol and glucose (blood sugar) levels. There are very easy tests that can be performed to determine cholesterol and glucose levels.
Breathing is one of the most basic but also one of the most important processes in the human body, and it directly affects the ability to exercise. Aerobic testing can test your maximal and submaximal exercise capacity.
