What does flexibility measure?

Flexibility specifically measures the range of motion of joints. This aspect of physical fitness is vital because it directly influences how well the joints can move through their full spectrum of motion without discomfort or restriction. A greater range of motion can enhance performance in physical activities, reduce the risk of injury, and improve postural alignment.

Flexibility can be affected by several factors, including muscle elasticity, joint structure, and the state of the surrounding connective tissues. Individuals who have good flexibility can often perform movements more easily and efficiently, which is particularly beneficial in activities such as dancing, gymnastics, and certain sports.

In contrast, muscle strength measures the ability of muscles to exert force, body weight reflects the total mass of an individual, and body fat percentage indicates the proportion of fat in the body. These concepts are related to overall fitness, but they do not pertain to flexibility specifically.
