Probably somewhere like this. It’s probably the non-weight bearing nature of cycling that is the main factor

The collarbone is a relatively weak member in the human skeletal system. It is vulnerable when the shoulder has a high energy impact.

And thats not to cast aspersions, just a thought.

You mean aspersions?

Ya agreed.

Lizzie Deignan has mentioned in a couple places part of the calculus for her husband's retirement were some scans that showed he was having some bone density issues given the lack of impact exercise.

Ya, that too!

Walk the dog! Walk to the pub! Get bone dense!

There has to be a public health campaign in this somewhere ...

[unterhausen]

There have been people trying to scare long distance cyclists with the bone density issues. I suspect I get enough weightlifting in by getting out of a chair, because I would have to lose almost 40 pounds to get back to my racing weight. One thing that did scare me a little is the assertion that dehydration can promote bone density loss. I can be bad about hydration. I fail to be convinced that the nature of cycling is the causative factor. The suggested exercises to combat bone density loss don't make a lot of sense to me.

Wonder if he got any metal in his femur..6 months, that's amazing...

That's why its a good target for elbow and hammer fist strikes...just sayin'.

The biggest factor is probably low weight of the cyclists, especially at the pro level where many are at the extreme end, when it comes to bone remodeling. It would be interesting to look at data comparing ultra thin guys with some of the bigger guys like sprinters.

I agree and I'm not sure what an age matched control tells you when it comes to bone density. It seems to me that you need to control for other factors beyond age. As you point out cyclist are generally lower in weight to begin with.

It would be interesting to look at the primary literature on this rather than the reporter's take on it.

Low weight, calorie restricted diets, and extreme endurance sports probably are all detrimental to bones to some extent. But running into walls at 30+ mph is far worse. I don't see any reason to speculate on relative bone density in cyclists for the extent of Froome's injuries.

Indeed. That fellow who just won the boxing heavyweight championship of the world would have suffered the same awful fate as Froome, I bet.

Who knows, perhaps even worse if some cyclists are somewhat weaker in bone structure, but otoh more flexible and supple in general. But as you said, 30+ mph against a hard wall...even Gumby gets hurt.
