Researchers find physical activity in youth leads to stronger bones in old age
PostedMarch 26, 2014
(Medical Xpress)—A team of researchers with members from the U.S. and Australia has found that people who exercise when young tend to increase the size and strength of their bones, which appears to make for lifelong benefits. In their paper published in Proceedings of the National Academy of Sciences, the team describes how they studied the bones in the arms of professional baseball players over the course of their lives and how their activities impacted bone size and strength.
Everyone knows that exercise causes muscles to grow bigger and leaner, now it appears it offers similar benefits for bones as well. In this new study, the research team enlisted the assistance of 103 professional baseball players to learn more about the impact of exercise on bones.
In their study, the researchers found that the ball players had up to twice the bone strength in their throwing arms (humeral diaphysis bone) as in their non-throwing arm—as measured by bone size and density.
