Boosting Physical Strength as We Age

A key pillar of human longevity is our ability to remain physically strong and active as we age. Frailty is an all-too-familiar downside of growing old. But there is much we can do to slow down and even reverse the process that leads to the weakening of our limbs. In this episode of the Live Long and Master Aging (LLAMA) podcast, we delve into the latest clinical discoveries that could help us stay strong and vital for much longer. Prof. Stuart Phillips, director of the Physical Activity Centre of Excellence (PACE) at the Department of Kinesiology at McMaster University, Hamilton, Ontario, explains how laboratory research into mitochondrial health is being applied to human physiology. Dr. Phillips is a member of the advisory board of Amazentis, the Swiss life science company, which has partnered with the LLAMA podcast to produce this episode.

“I’ve been really impressed with the scientific trajectory that the company (Amazenitis) has taken. It’s backed by a lot of good research.”

• Making the connection between research in laboratory animals and humans.

“We’re actually eager to conduct some research with this compound because we think that the upside of it for aging people is tremendous.”

• Lifestyles that give meaning to life.
• The protein question – how much and what kind?
• The declining immune system with aging. Why are exercise king and nutrition queen?

“Being physically active is the forgiver of a lot of sins.”
