Osteoarthritis Patients Will Benefit From Jumping Exercise
The English is a bit shaky in spots (perhaps it was translated?), but the findings are clear enough:
Progressive high-impact training improved the patellar cartilage quality of postmenopausal women who may be at risk of osteoporosis (bone loss).Specifically, 80 women from 50 to 65 years old, who also had knee pain, participated in this Finnish study. They all had “mild knee OA,” it’s important to note. One set of subjects underwent a “supervised progressive high-impact exercise program” three times a week for 12 months. The quality of their patellar cartilage (which is located under the kneecap) improved with jumping and exercises that required “versatile rapid movements.”
Jump for better knee health! Uh, yeah sure ...
Jumping around with bad knees is not the first thing I would do. What we don’t know here is significant, I suspect. That “mild OA” may correlate with milder knee pain and minor damage, which makes more vigorous activities possible. I know plenty of regular readers of this blog who would shudder at the idea of “jumping” their way to knee health; their pain is brought on by much less strenuous exercises.
Also, it’s hard to tell what “supervised progressive high-impact exercises” means, but “supervised” and “progressive” suggest that subjects with bad knees weren’t cut loose to do jumping jacks during the first week.
My takeaway from this study is probably different from what the authors intended. I’m far from sold on advising knee pain patients to engage in jumping activities to improve their kneecap cartilage. I bet there are less impactful activities that would achieve the same end. However, if you’ve got good knees, exercises that stress your cartilage such as those that involve a reasonable amount of jumping are probably a good idea. They can help you develop stronger joints and ward off problems in the future.
An ounce of prevention!
