The science of strength, muscle, and training for longevity

This week, on episode #239 of The Drive, Peter sits down with Andy Galpin, Ph.D., Professor of Kinesiology at California State University at Fullerton. In this episode, Andy explains the anatomy, microanatomy, and physiology of the muscle, what it actually means to undergo hypertrophy of the muscle, and more, including:

  • Contrasting strength, power, and force production and how they inform us about training for longevity
  • Muscle energetics: Fuels that provide energy to muscles, and the importance of protein
  • Muscle fibers: modulation between fiber types with movement and changes in fibers with training and aging
  • Microanatomy of fast-twitch and slow-twitch muscle fibers
  • Factors that determine one’s makeup of muscle fibers, and how adaptable they are with training
  • Changes in muscle and muscular function that occur with aging
  • Training plan for the hypothetical client
  • How to properly incorporate isometric exercises into a workout
  • More

Training principles for mass and strength

In this episode (#235), Layne Norton, Ph.D. shares training principles that non-powerlifters can apply to improve muscle strength and mass. Layne goes in-depth on creatine supplementation, including the benefits for lean mass and strength, and addresses the common arguments against its regular usage. Additionally, Layne touches on many areas of nutrition, including how his opinions have changed on certain topics. Layne also touches on the subjects of protein, fiber, and fat in the diet, as well as the different tools and dietary approaches for energy restriction.

The importance of muscle mass, strength, and cardiorespiratory fitness for longevity

In this "Ask Me Anything" episode (ep. #176, AMA #27), Peter and Bob discuss the longevity benefits from greater cardiorespiratory fitness (CRF) and greater muscle mass and strength. Conversely, they dive deep into the literature showing a rapid increase in morbidity and mortality risk as fitness levels decline with age. They also try to tease out the relative contributions of CRF, muscle mass, and strength. Additionally, they discuss the impact of fasting on muscle mass, the potential tradeoffs to consider, and finish by discussing why it’s critical to maximize your fitness level.

Improving body composition, female-specific training principles, and more

In this episode (#228), Holly Baxter, APD discusses how she would design a nutrition and training program for a hypothetical female client wanting to improve her physique through the addition of lean muscle and loss of body fat. She explains reasonable expectations for gaining muscle and the value of a “reverse diet” for maintaining weight loss, and she shares her favorite exercises. She also talks through some female-specific training considerations such as programming, reps, volume, hormone replacement therapy, and more.
