In this video from our "Science of Protein" podcast, Rhonda covers:
- The shocking truth about how muscle mass & strength decline with age in the absence of resistance training
- The metabolic health benefits of muscle
- How more muscle prevents a common "death sentence" in old age
- Why people tend to lose muscle mass as they get older
- Why older adults need more protein to maximally stimulate muscle protein synthesis
- How reducing physical activity affects anabolic resistance in older adults
- How exercise negates anabolic resistance

Muscle News
- Late life exercise may partly reset epigenetic aging in skeletal muscle.
- Endurance training may leave a mitochondrial "muscle memory" that enhances training adaptations after a period of inactivity.
- Lean pork stimulates more muscle protein synthesis after exercise than high-fat pork, despite equal protein content
- Cold-water immersion reduces muscle protein synthesis by 30% post-exercise, potentially inhibiting the uptake of essential nutrients for muscle repair and growth.
- Resistance exercise in older adults boosts levels of cardiotrophin-like cytokine factor 1—a myokine released during exercise—by nearly 70%, improving muscle strength, bone density, and metabolic functions.
