Exercise and Bone Health Study

Osteoporosis is a bone disease that impacts older adults. But we know that lifestyle habits in childhood (such as exercise) can prevent osteoporosis from developing. Research has found that children who exercise have healthier and stronger bones. 

One way that we think exercise builds bones is by the muscle releasing messengers into the blood which help bones grow. Our main goal is to see how this works. We also want to see if it is different in girls and women. This information will be important to understand how exercise can help reduce osteoporosis in women.

 

To do this, we are going to answer the following questions:

  • Do the messengers released by muscle during exercise benefit the growth of bone?
  • Is this different in girls and women?

 

What does this study involve?

This study involves 2 visits to the McMaster Children’s Hospital. During the first visit, we will measure the participant's fitness level. Then we will give them a small device called an accelerometer to wear for a week to measure their physical activity. At the second visit, the participant will bike for an hour with a break half way through. We will take blood samples at this visit. Participants will be able to watch a movie while biking.  Participants will receive a $40 gift card upon study completion and we will cover parking costs.

 

Who is eligible to participate?

We are looking for 8-10 year old girls, who are healthy (no diagnosed medical conditions) and recreationally active. If you are unsure whether your child is eligible or not, please contact us.
