What is a key contributing factor to rotator cuff injuries?

Repetitive overhead motions are a primary contributing factor to rotator cuff injuries because these motions place excessive strain on the tendons and muscles of the shoulder. Activities that require frequent overhead lifting, throwing, or reaching can lead to inflammation, microtears, and eventual tears in the rotator cuff.

In the context of rotator cuff injuries, the shoulder's complex structure and the demands placed on it during repetitive movements can result in overuse syndromes. When these motions are performed repeatedly, particularly without adequate rest or conditioning, the integrity of the rotator cuff can deteriorate over time.

In contrast, while increased flexibility can sometimes help improve function and reduce injury risk, it is not specifically a contributing factor to rotator cuff injuries. Heavy lifting can lead to other types of injuries but is more associated with acute trauma rather than the chronic overuse scenario typical of rotator cuff problems. Age-related decline in muscle mass is a concern for overall physical health and can impact strength but isn't a direct cause of injury itself; rather, it may compound issues related to shoulder function, particularly in older adults.
