After getting 4 stress fractures in the last 8 months, missing out on the entire cross country season, I got a bone scan and was diagnosed with osteoporosis with a bone density of -2.0. Osteoporosis seems to be very rare in teenagers, especially males, so I am wondering what I should do to continue training and try to maintain my fitness. I had trained 70mpw the summer going into this year which was the start of my stress fractures. My doctor said I can’t go above 30mpw and wanted me to stay under 20 mpw for the first few months. I was thinking cross train recovery days and run workouts with everyone else. Does anyone have any advice on how to deal with this as I am feeling kind of hopeless right now.
I assume that -2.0 is your T-score.
Low bone density among both young and old female distance runners is a well-known condition with a large literature. I've seen relatively little about low bone density among male distance runners, although I think that it is much more common than is generally believed. I recall an article in a running magazine about fifteen years ago that discussed low bone density among middle-aged male runners; at least one physician noted that cases he'd seen typically involved (as I recall) thin, high-mileage runners with low body fat and "restrictive" diets.
Although I've read a lot about the subject, and am a longtime patient of one of the country's leading experts on osteoporosis who has studied and treated many amateur and professional athletes (including rather young male and female runners) with low bone density, I don't consider myself an expert. Theories about what causes osteoporosis and how to treat it are still hotly debated. It is certainly not a matter of simply telling people to drink more milk, although that may be a perfectly reasonable thing to do.
Are you working with an endocrinologist who specializes in metabolic bone disorders, including osteoporosis and osteopenia in relatively young males? My impression is that not many endocrinologists, and far fewer internists and orthopedists, have the background to evaluate and treat cases like yours, so you may have to do some digging around for someone with the right expertise and experience. (You can probably find a number of sports medicine specialists who treat young female athletes with low bone density, and they can probably give you some worthwhile advice, but the hormonal issues for young female athletes are likely to be significantly different.)
Until you get more guidance and support for your proposed training program, I would be cautious about trying to maintain high training volume by substituting a lot of cross-training to make up for the lower running volume, because high training volume itself may -- and I want to emphasize the word "may" -- create more problems for your bone density, even if the lower impact of the cross-training allows your stress fractures to heal. One good thing about stress fractures is that they generally heal without many complications if you relieve the stress on the bone for what is usually a fairly predictable period of time. Low bone density creates a different set of challenges, and you need to make sure that you're taking the right steps to keep your bones healthy and strong in the very long term.
