Exercise may be beneficial for weight loss and maintenance, heart health and preventing many serious health conditions, but too much may end up causing individuals a lot of pain, according to a new study.

Researchers say middle-aged men and women who engage in high levels of physical activity may be putting themselves at an increased risk for developing osteoarthritis.

The team from the University of California at San Francisco evaluated the activity levels of 236 asymptomatic men and women aged 45 to 55. Subsequent MRIs indicated a link between increased activity levels and frequency and severity of knee damage.

The study also found that certain activities, like jogging or jumping, are worse for joint health. "Low-impact activities, such as swimming and cycling, may protect diseased cartilage and prevent healthy cartilage from developing disease," said study author Dr Christoph Stehling.

Osteoarthritis is a degenerative joint disease that causes pain, swelling and stiffness. The Centers for Disease Control and Prevention reports that it is the most common form of arthritis in the U.S., affecting an estimated 27 million American adults.

According to the Mayo Clinic, among some of the natural treatments for joint pain are nutritional supplements containing glucosamine and chondroitin, acupuncture, tai chi and yoga.
