Irisin. How Exercise Strengthens Your Bones

We here at Cardio High are all about making sure that people can get a great, intense workout without having to worry about hurting yourself. And lucky for us a new study is out that says one way to make sure your bones are strong while working out is to…. work out.

This comes from a Tufts University School of Dental Medicine study, which found that “two weeks of voluntary wheel running [for mice] induces higher expression of irisin.” What is irisin? It’s a supposedly important hormone that our body’s produce and which some people believe does nothing or doesn’t even exist.

But this study not only found what they believe to be irisin, at least in mice, but it was also linked with more bone formation and a greater thickness of bone.

There is a still a lot of mystery around the true effects of the irisin or why it does what it does, but more importantly it backs up previous studies that have found one way to keep your bones healthier in old age is to put them to use.

This kind of density may very well be a “use it or lose it” type thing, so we suggest dragging your bones to the gym as soon as possible.
