Stuart Phillips, PhD, is a leading kinesiology professor at McMaster University, specializing in exercise and nutrition's effects on muscle health. In this conversation, he highlights the critical role of muscle for longevity and the need for older adults to increase protein intake. He questions if current protein recommendations are too low and discusses the effects of anabolic resistance, especially in aging. Practical tips on protein timing and recovery strategies provide actionable insights, making a strong case for resistance training as a means to combat muscle loss.

Episode notes
Recovery and IGF-1
- Protein aids in recovery, especially for repair.
- IGF-1's role isn't as crucial for repair as macronutrients.
mTOR Complexes
- Leucine activates muscle protein synthesis via mTOR.
- mTORC1 is nutrient-sensitive, mTORC2 is exercise-sensitive.
Androgen Receptors
- Androgen receptor content increases with resistance training, correlating with muscle protein synthesis.
- Testosterone likely increases androgen receptors, though other factors may bind.
