What is defined as the range through which a joint can be moved?

The range through which a joint can be moved is referred to as the "Range of Motion." This term specifically describes the extent of movement that is possible at a particular joint, measuring both the flexibility of the surrounding muscles and the joint's anatomy itself.

Range of motion is crucial for overall movement efficiency and athletic performance, as it impacts activities ranging from daily tasks to complex physical exercises. Factors such as age, injury, and physical training can influence an individual's range of motion.

In contrast, flexibility is related to the muscle's lengthening ability, joint stability refers to the joint's ability to maintain proper alignment and function during movement, and muscle endurance measures how long a muscle can sustain a given activity without fatigue. Each of these concepts interacts with range of motion but focuses on different aspects of physical capabilities or joint function.
