What is the role of range of motion (ROM) exercises?

The role of range of motion (ROM) exercises is primarily to maintain or improve joint flexibility and movement. These exercises involve moving a joint through its full arc of motion and are crucial for preserving the functionality of the joints, preventing stiffness, and promoting overall mobility. Regular ROM exercises can help alleviate discomfort, improve circulation to the affected areas, and facilitate better range of motion, which is essential for daily activities and overall physical health.

While other options address different aspects of physical fitness and health, such as muscle strength, cardiovascular endurance, and weight management, their primary focus is not on joint flexibility and movement. Therefore, B is the most accurate choice regarding the specific purpose of ROM exercises.
