What type of exercise focuses on improving the range of motion of a joint?

The focus of improving the range of motion of a joint is most accurately represented by ROM (Range of Motion) exercises. These exercises are specifically designed to enhance the movement capability of joints through controlled stretching and movement. By performing ROM exercises, individuals work to maintain or increase their mobility, which is crucial for overall physical function, especially in rehabilitation settings.

Flexibility exercises, which might seem similar, mainly aim to increase the elasticity of muscles and tendons rather than specifically targeting the movement of the joint itself. While they do contribute to overall mobility, they are not exclusively focused on the joint's range of motion, which can sometimes lead to confusion.

Endurance training and resistance exercises have different objectives entirely. Endurance training emphasizes cardiovascular fitness and prolonged physical activity, whereas resistance exercises primarily focus on building muscle strength through weight lifting or resistance bands, neither of which specifically aims to increase joint range of motion.

Thus, the term "ROM exercise" directly aligns with the goal of improving joint range, making it the most precise choice.
