How Lifelong Exercise Changes Everything about Aging. Tony Boutagy, PhD (host) Interview Dr. Professor Scott Trappe - one of the world's leading experts on muscle physiology and aging.

Professor Scott Trappe is a renowned exercise physiologist at Ball State University's Human Performance Laboratory. His groundbreaking research on lifelong athletes, muscle fibre physiology, and aging

Episode Highlights:

00:00 – Scott's journey from swimming to studying the world's best aging athletes

04:06 – The viral MRI study: what those shocking images really tell us about aging

05:46 – Where we measure muscle and why the vastus lateralis tells the whole story

09:47 – Muscle mass, strength, and power: when each peaks and declines across life

12:00 – Why the "peak at 25, decline forever" model is wrong if you exercise

16:49 – Fast-twitch fibre loss: the one thing that changes with age (and what helps)

20:49 – Do masters athletes preserve fast fibres better than regular exercisers?

23:30 – Sex differences in muscle aging: what Scott's data shows about men vs women

27:59 – Are females really different in their training response to aging?

34:39 – The remarkable finding: how older muscle responds to exercise like "stress and chaos" vs "coordinated response"

40:19 – Why Scott's "mashed potatoes and gravy" approach beats complex programming

45:18 – The truth about aerobic vs resistance training: what Scott does at 59

50:56 – Scott's resistance training prescription: why 2-3 days beats complicated protocols

54:16 – What Scott actually does: 500+ hours of exercise per year and loving it

56:03 – Why Scott finally added resistance training (and what changed his mind)
