In terms of kinesiology, what does the term "flexibility" specifically refer to?

Flexibility specifically refers to the range of motion available at a joint. This encompasses how far a joint can move in various directions, which is influenced by factors such as the structure of the joint, the muscle length, and the surrounding connective tissues. Flexibility is a critical aspect of physical fitness because it directly impacts performance in activities that require movement, such as sports, exercise, and daily tasks. Increased flexibility can enhance athletic performance and reduce the risk of injuries by allowing joints to move freely through their complete range of motion. The term is distinct from other concepts such as muscle strength, stability, or the ability to perform high-impact activities, all of which are separate components of physical fitness but do not define flexibility itself.
