Question: 1 / 415

What occurs during flexion at a joint?

Joint angle increases

Joint angle stays the same

Joint angle diminishes

During flexion at a joint, the angle between the bones that make up the joint decreases. This movement is characterized by the bending of a limb or a segment of the body, bringing the two body parts closer together. For example, when you bend your elbow, the angle between the forearm and upper arm diminishes, which is a clear demonstration of flexion.

Flexion can occur in various joints, such as the hips, knees, and shoulders, and is a fundamental movement pattern in many exercises and activities. Recognizing this concept is crucial for personal trainers, as it helps in designing effective workout routines that incorporate movements involving flexion, promoting flexibility and strength in the joints. Understanding joint actions like flexion also aids trainers in ensuring proper form and technique during physical activity, reducing the risk of injury.
