Final answer:
Hyperextension of joints can lead to injuries; flexibility exercises like stretching aid in joint health; understanding angular movements is essential for exercise safety.
Explanation:
Hyperextension is the abnormal or excessive extension of a joint beyond its normal range of motion, resulting in injury. Examples include moving the neck back to look upward or bending the wrist so that the hand moves away from the forearm. Exercises that cause hyperextension of a joint can lead to strain or damage to the joint structures.
Flexibility exercises like stretching, yoga, and tai chi can help improve joint flexibility, decrease the risk of injury, and enhance range of motion. These exercises focus on lengthening muscles and keeping them limber to maintain overall joint health.
Angular movements involve changes in the angle between bones at a joint and include flexion, extension, hyperextension, abduction, adduction, circumduction, and rotation. Understanding these movements is crucial for proper exercise execution and preventing injuries during physical activities.
