What is the definition of range of motion in exercise theory?

The definition of range of motion in exercise theory specifically refers to the extent of movement possible at a specific joint. This is an important concept because it encompasses the degrees through which a joint can move in various directions, which is critical for understanding joint health, flexibility, and overall physical performance.

Range of motion is influenced by various factors, including the structure of the joint, surrounding muscles and tendons, and overall flexibility. A greater range of motion can enhance athletic performance, improve posture, and reduce the risk of injury.

In contrast, flexibility of all joint types doesn't capture the specificity required to define range of motion, as flexibility can pertain to muscular elasticity rather than joint movement alone. The total distance a muscle can contract is related to muscle strength and length but does not directly address joint movement. Similarly, the speed at which a joint can move pertains to dynamic aspects of exercise and performance but does not define the range of motion which is strictly about the limits of joint movement itself.
