In September 2010, I wrote a blog post explaining that yoga IS a weight-bearing regime. My intention was to counter misinformation that appeared in a 2007 Time Magazine about yoga's limitations. The author of the article had the ignorance and audacity to claim that yoga was not weight-bearing nor could it help alleviate osteoporis!
Well, research presented in the article, "Good to the Bone" by Catherine Guthrie in the May 2011 issue of the Yoga Journal (alas - I admit, somehow I didn't read all my issues from a year ago!) further reinforces and provides more support for yoga's value in helping to build strong bones and even to reverse bone loss in people suffering from osteoporosis. Aah - vindicated once again from silly misinformation promulgated in the mass media!
I expanded my knowledge of yoga and our bones by reading this informative article. Some of the key points Ms. Guthrie made included:
1) "Yoga is a weight-bearing exercise because you hold the weight of your body up against gravity. Resisting gravity puts a mild stress on the bones. That stress forces bones into laying down new growth. In this way, yoga is no different from jogging, walking, or playing tennis."
2) However, yoga's advantage over other weight-bearing exercise is that it doesn't "damage cartilage or stress the joints. Instead, it lengthens muscles and holds them there, creating tension in the bone."
3) In standing poses like Warrior II, "you're also adding force to the shoulder joint. Because you're holding your arms out away from your body, you're putting a lot more stress on the head of your humeras (that's the long bone in the arm or forelimb that runs from the shoulder to the elbow) than you would if they were hanging at your sides."
From Ms. Guthrie's article I also learned the results of a small pilot study conducted by Dr. Loren Fishman on the effect of yoga on building bone density. He gathered a group of 18 people with osteoporosis or osteopina and an average age of 68 years. Everyone received a baseline bone density test and two groups were created - a control group of 7 individuals and a test group of the remaining 11 individuals. The people in the test group learned a sequence of 10 yoga poses (including upward and downward facing dog, bridge pose, triangle pose, etc.), each of which were each held for 20-30 seconds. The daily (hey - note that it was d-a-i-l-y ! ) yoga routine lasted about 10 minutes.
After two years of charting the groups' progress, Dr. Fishman had everyone get a new bone scan. The members of the control group either maintained or lost bone. However. Fishman was shocked to observe that nearly every individual who had practiced yoga gained bone in the spine and the hip. Dr. Fishman admitted his surprise and stated, "By putting tremendous pressure on the bones without harming the joings, yoga may be the answer to osteoporosis."
Granted, I am a bit late in sharing these wonderful results- but, better late than never in discovering more evidence that yoga does a body good, especially your bones!
One other important point the article made is that good nutrition , a diet RICH in fresh fruits, veggies - especially broccoli, cabbage, kale, and zucchini and LOW in cheese, meat, eggs, fish) goes hand in hand with yoga for building strong bones. Despite the propaganda and conventional "wisdom" in the media, you don't need to eat a lot (or any) dairy to build strong bones.
Yours for building strong bones with daily yoga!
