Which is a risk factor for developing rotator cuff tears?

Age-related degeneration is indeed a significant risk factor for the development of rotator cuff tears. As individuals age, the tendons of the rotator cuff can undergo changes such as degeneration, thinning, and calcification, which contribute to an increased vulnerability to tears. The rotator cuff consists of a group of muscles and tendons that stabilize the shoulder and allow for a range of motions. Over time, repetitive use and natural wear and tear can lead to a decrease in the integrity of these structures.

Younger individuals in high-impact sports may also experience acute injuries to the rotator cuff, but those injuries are not primarily due to age-related degeneration. Obesity can contribute to shoulder conditions by affecting overall joint health, but it is not as directly correlated to rotator cuff tears as age. Excessive stretching is generally aimed at improving flexibility and does not inherently increase the risk of tears. Rather, it can be part of a regimen to maintain shoulder integrity and prevent injury, when done appropriately. Therefore, age-related degeneration stands out as a clear risk factor due to the cumulative effects of aging on the rotator cuff.
