What terminology refers to the range of motion around a joint?

The term that refers to the range of motion around a joint is flexibility. Flexibility is a key attribute in physical fitness, as it describes the ability of muscles and tendons to stretch and allow joints to move freely through their full range of motion. This is crucial not only for performance in various physical activities but also for preventing injuries and improving overall mobility.

In the context of exercise and fitness, flexibility can enhance athletic performance by enabling better movement mechanics and reducing the risk of strains. It is important to incorporate flexibility training, such as stretching exercises, into a regular fitness routine to promote optimal joint function and health.

In contrast, endurance pertains to the body's ability to sustain activity over a prolonged period, strength relates to the amount of force a muscle can exert, and balance refers to the ability to maintain stability and control during movement. While all these factors are important components of fitness, they do not specifically define the range of motion around a joint, which is why flexibility is the correct terminology in this question.
