Repetitive strain can create microtrauma to joints and adjacent soft tissue, and lead to osteoarthritis in later years. Squatting, heavy physical labor, occupational knee bending, and a history of regular sports participation that can cause abnormal wear and tear of the knee joints are risk factors for knee arthritis. Repetitive or forceful motions performed with the hands can contribute to osteoarthritis. And even long hours at the computer can strain and perhaps prematurely age your hands. At the first sign of chronic strain or pain, see a physician.
Regular exercise is essential.
It creates stronger and more flexible joints. Exercise doesn't have to be strenuous. Consider a cross-training program that includes a variety of exercises and light weight training. The use of weights builds denser bones and strengthens the muscles, ligaments, and tendons associated with joints. Feed your joints right.
