Which aspect of exercise is important for improving joint range of motion (ROM)?

Improving joint range of motion (ROM) is significantly influenced by flexibility and ROM exercises, making this choice the most suitable. When individuals engage in flexibility exercises, they work on stretching the muscles and surrounding connective tissues. This dynamic activity helps to increase muscle elasticity, allowing joints to move through a greater range. Additionally, ROM exercises specifically target the joints themselves, encouraging the lubricating synovial fluid within the joints and promoting healthier joint function overall.

In contrast, endurance or strength training primarily focuses on the body's ability to perform activities over time or to develop muscle mass, respectively. While these aspects are important for overall fitness and can contribute indirectly to joint health, they do not directly enhance flexibility or the capacity of joints to move freely through their full range. Long durations of inactivity would actually hinder the improvement of ROM because immobility can lead to stiffness and decreased flexibility in the joints. Thus, the focus should remain on flexibility and ROM exercises to effectively achieve better joint mobility.
