Navigating bone health: early life influences & strategies for improvement & injury prevention

Video Description

In this episode from July 2022, Peter dives deep into the topic of bone health and explains why this is an important topic for everyone, from children to the elderly. He begins with an overview of bone mineral density, how it’s measured, how it changes over the course of life, and the variability between sexes largely due to changes in estrogen levels. From there he provides insights into ways that one can improve bone health, from exercise to nutrition supplements to drugs. Additionally, Peter discusses what happens when one may be forced to be sedentary (e.g., bedrest) and how you can work to minimize the damage during these periods. While this original episode is an AMA, it is available in full to all listeners as a special rebroadcast.
