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.

Topics covered

  • PACE – a community access exercise facility for special populations over the age of 55
  • The impact a period of muscular disuse has on the body
  • Why Covid has had such a marked effect on older people through inactivity

“Most clinicians would acknowledge that a bout of physical inactivity, bedrest or illness is a watershed moment for older people.”

  • The classic image of the older, retired person and why the notion of aging is associated with a decline in our physical functions is being challenged.
  • Pursuing a goal of aging as healthily as we can for as long as we can.
  • Understanding the phenomenon of Sarcopenia

“I don’t think that in your lifetime or my lifetime, we’re going to see the magic, so-called, anti-aging pill."

  • The condition known as frailty.
  • Ten thousand steps per day – why that number?
  • Type II diabetes and psychical activity.
  • Working with Amazentis to explore the benefits of Mitopure, a pure form of urolithin A, in humans.

“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.”

  • Is there a recipe for good exercise?
  • Why do we run marathons?
  • The power of walking
  • Spreading the message of healthy aging through social media

“If you’re up for a walk seven days a week, my bet is that you’re in pretty darn good shape.” The Live Long and Master Aging podcast shares ideas but does not offer medical advice. If you have health concerns of any kind, or you are considering adopting a new diet or exercise regime, you should consult your doctor.

Peter Bowes

Journalist Podcaster

Peter Bowes is a news correspondent for the BBC and host of Live Long and Master Aging (LLAMA) - a podcast that explores the science and stories behind human longevity.

He is trained as a biologist and worked in medical research, early in his career, in London. For more than three decades, as a reporter, he has covered news and current affairs for television, radio, and digital outlets, including the BBC. He has also made documentaries, specializing in human longevity and wellbeing. Based in Los Angeles, Peter is interested in science-based regimes that promote healthy aging. The Live Long and Master Aging podcast, launched in 2017, explores issues, including dietary interventions, related to healthspan or the number of years that we enjoy optimum health. In 2020 he founded HealthSpan Media LLC to produce media content focusing on the biology of aging, food, movement, and mindfulness. Peter, an avid exerciser, enjoys hiking, swimming, and weightlifting, as part of a constantly moving lifestyle.
