Exercise in Youth Makes Bones Strong in Old Age

People at risk of getting osteoporosis, or brittle bone disease, are usually told to exercise. New research findings suggest this is sage advice — that should be handed out decades earlier.

Researchers at the University of Gothenberg in Sweden analyzed the bone density as well as current and past exercise habits of men at various ages. Among 2,300 18-year-olds, "those who actively did sports, and also those who used to do sports, had greater bone density than those who had never done sports," explained physiotherapist Martin Nilsson, who conducted the research as part of his doctoral thesis, in a statement.

"The bones respond best when you're young, and if you train and load them with your own bodyweight during these years, it has a stimulating effect on their development," Nilsson said. "This may be important for bone strength much later in life too, so reducing the risk of brittle bones."

It is not clear whether this link between exercise and bone strength at these ages is due solely to this being a critical period for bone development, or whether the type of exercise engaged during this period (competitive sports) is more likely to help bones than exercises common in other periods of life.

Still, exercise, at any time in life, will likely have a beneficial impact on the bones. And the sooner you start the better.
