According to new research conducted at the Tehran Medical University in Iran frequent cyclists and people who spend long periods of time in a squatting position may be at an increased risk of developing arthritis in their knees.
Arthritis of the knee, or osteoarthritis, is the most common type of arthritis to attack people and occurs when the cartilage of the joints break down. It usually begins after a person reaches middle age and can be disabling.
To determine whether occupational or leisure-time activities could influence the risk of a person developing the condition, Dr S. Dahaghin and colleagues compared 480 people with osteoarthritis of the knee and 490 arthritis-free controls for the study.
According to the study people who cycled for more than 30 minutes daily were two times more exposed to the risk of developing arthritis of the knee. And individuals who spent more than 30 minutes a day squatting were at 1.5 times increased risk.
The Tehran researhers say that their study proves that overuse of a joint can increase arthritis risk. Researchers believe that people should be more aware about the damage they are doing to their joints while performing their normal, everyday jobs or while indulging in leisure activities.
“Education on preventable risk factors should be considered in order to ensure people use knee joints appropriately and avoid overuse", researchers concluded.
