Osteoperosis/bone density(5 posts)

I was asked this question by a fellow cyclist and have not really found an answer. Maybe you all can help. Does cycling effect bone density despite not being considered a weight bearing movement? I though that there may some minute benefit if not more due to the forces applied when cycling. Clairification please? Thanks!!

This is from a research review article in the August 2001 Strength and Conditioning Journal (published by NSCA). A study was done on the effect of stationary cycling on bone density in post-menopausal women. (Any of those lurking around here?) They saw a significant increase in bone density in both the lumber spine and femur, compared to controls who lost bone density. Training levels have to be at least 60% of heart rate max, enough to elicit aerobic benefits.

What I take from this is that for healthy adults with adequate dietary intakes of calcium and Vit D, cycling will be effective in maintaining bone density. Most of us are working at those training levels. If anyone want reference to the review article (includes other types of exercise) or the original study, let me know.

Thank you for responding back in regards to this question. I would very much like reference to the article. Thanks again, the info is what I was looking for. Especially research related to validate content.

The review article: "Effects of Exercise on Bone Mineral Density on Potsmeopausal Women, Ross & Denegar. Strength and Conditioning Journal, Vol.23, no.4., pp.30-35. (Published by National Strength and Conditioning Assoc.)

The research article on stationary cycling:
Bloomfield et.al. Am.J.Phys.Med.Rehabil. 72:204-209. 1993.

Your best bet to find these is a university library, or possibly the Internet.
