Golfers with knee osteoarthritis should walk the course, not ride, for better health benefits, revealed new research from the Shirley Ryan AbilityLab and Northwestern Medicine.
Knee osteoarthritis, which causes swelling, pain and difficulty moving the joint, is one of the leading causes of disability in this age group. This study is the first comparing the health benefits of walking the golf course versus using a cart, as well as the first to use a blood-based biomarker analysis in knee osteoarthritis during a prolonged sporting event. The findings will be presented April 28 at the Osteoarthritis Research Society International Annual Meeting in Liverpool, England.
The health benefits of golf have decreased as the number of people who ride the course has increased over the past 20 years. In the late 1980s, 45 percent of all rounds of golf were played with a golf cart. By 2006, 69 percent of rounds were played with a cart. During this same time period, activity has decreased among Americans, while obesity has increased. "Individuals with knee osteoarthritis are often concerned about pain and may be more likely to use a golf cart," said lead study author Dr. Prakash Jayabalan, a physician scientist at the Shirley Ryan AbilityLab and an assistant professor of physical medicine and rehabilitation at Northwestern University Feinberg School of Medicine.
The researchers found that, prior to starting either round, the golfers with knee osteoarthritis had an average pain score of 1.3 (on a scale of 0-10). When they played the round walking the course, they had an average 2.1-point increase in pain score. When they played the round using the golf cart, they experienced on average a 1.5-point increase, a difference that is not clinically significant. The research team also measured blood-based biomarkers of cartilage stress and inflammation. Although both methods of transportation caused an increase in these markers (as would be expected with regular walking), there was no difference between the rounds.
When walking the course, golfers with knee osteoarthritis spent more than 60 percent of the round with heart rates in the moderate intensity heart rate zone. When driving on a cart, golfers spent 30 percent of the round in this range. While this figure is lower, it still fulfills daily exercise recommendations. Although walking the course offers the most significant health benefits, the study found that riding the course with a golf cart during a round -- and the requisite moderate walking that comes with it -- still offers cardiovascular benefits and helps fulfill daily exercise guidelines.
"Bottom line: walking the course is significantly better than using a golf cart, but using a golf cart is still better than not exercising at all," said Jayabalan.
