Sports
Since repetitive actions can contribute to the formation of arthritis, it becomes easier to understand why athletes are at higher risk of developing arthritis, as they put constant stress and pressure on their joints. Most athletes develop osteoarthritis. Even if exercise is effective in keeping people healthy, continuous muscle and joint tension are also not good. All actions of athletes involve using their joints during training, running, walking, jumping, etc. They put constant stress on their joints, increasing wear and tear on the cartilage that prevents friction between bones. If the joint moves with very little protection from the cartilage to cushion the friction, it leads to joint damage.
Likewise, sports injuries can accelerate the development of osteoarthritis. Examples are ligament injuries, such as anterior cruciate ligament (ACL) injury, which many basketball and football players incur, and orthopedic joint dislocations that can tear ligaments. Other injuries include fractures, rotator cuff tears, and direct damage to the cartilage due to forceful or sharp blows directly at the joint, such as from boxing and martial arts competition.
