It is well known that exercise is good for the heart, lungs and brain. But there is one part of our body that is often overlooked: our bones.

As we get older, our bones become less dense, which can ultimately lead to them becoming weak and more prone to fractures. From the age of around 35 we lose approximately 0.5% of bone mass per year. This accelerates once women reach menopause, and for men, after the age of around 50 years.
Although calcium and vitamin D are well known to be essential for healthy bones, studies have shown that exercise can slow, or even reverse, the decline in bone strength with age.
It is believed that exercise helps to keep our bones strong by putting them under stress and subjecting them to jolts and shocks. Each jolt is thought to send signals to bone cells that trigger them to grow back stronger. Bone also responds directly to the local muscle, which, if well-developed, gives additional bone-building benefits.
But what is the best type of exercise you can do, to strengthen your bones?
The Experiment
To find out, we teamed up with Dr Karen Hind, an expert in bone health at Leeds Beckett University. We and the Leeds team recruited elite male and female athletes – including Olympic medallists – from three different sports:
- Gymnastics
- Cricket
- Cycling
Studying these elite athletes allowed us to distinctly characterise bone density that may reflect the particular movements involved in different types of exercise.
This gave us an indication of what kind of exercises might benefit bone strength in the wider population and so might help avoid fractures in later life.
Each of our groups was analysed with a low radiation imaging method called a DEXA scan. This was used to measure the bone density in the athletes’ hips and spine, two common and serious problem areas for fractures in older people. The results were compared with the average bone density for people of the participants’ age and gender.
