Will bowlegs get worse if you frequently run?
Generally, bowlegs (O-shaped legs) will not worsen from regular running; in fact, running may bring certain benefits. However, attention should be paid to the amount of exercise. The detailed analysis is as follows:
Bowlegs are usually caused by either congenital or acquired factors. Running increases strength around the knee joints, helping to strengthen the muscles and ligaments on the outer side of the knees, thereby improving balance in knee movement. Additionally, it can help reduce knee joint wear and alleviate pain caused by degenerative changes. Therefore, running typically does not exacerbate bowlegs and may actually provide some benefits.
However, running generally subjects the legs to significant impact forces and loading, which may lead to joint and soft tissue injuries. Hence, it's important to progress gradually and avoid overexertion when running.
