If you've seen those viral MRI images comparing active and sedentary 70-year-olds, you've witnessed one of the most compelling visual demonstrations of how exercise shapes the aging process - but the story behind them reveals even more.
In this episode, Professor Scott Trappe - the researcher behind those images - explains what happens to muscle as we age and how exercise fundamentally alters this process.
You'll discover:
β’ What those MRI comparisons reveal about the aging trajectory
β’ When muscle mass, strength, and power peak and how exercise affects this timeline
β’ The reality of fast-twitch fibre changes with age and what training can reverse
β’ Why males and females show remarkably similar responses to exercise across the lifespan
β’ Scott's evidence-based approach that consistently outperforms complex programming
β’ How muscle with different training histories responds to exercise stimuli
β’ The finding that 90-year-old lifelong exercisers maintain muscle quality similar to 40-year-olds
β’ Why consistency matters more than complexity in long-term outcomes
This conversation explores what decades of research reveal about muscle adaptation and the aging process.
