In this episode of Hypertrophy Past & Present, Jake and Chris unpack a new hypertrophy study that illustrates how fatigue doesn’t just make training harder but can directly reduce the hypertrophic stimulus by lowering single-fibre mechanical tension. The episode opens in the Silver Era again with Henry Paschal’s 1950 “busy person” program then pivots into the core discussion: why fatigue mechanisms (CNS and calcium-ion related) dampen muscle growth, and what this implies for exercise order, rep ranges, and advanced training methods.
Key topics include:
- Henry Paschal’s 1950 routine
- A new “repetition duration” study
- How CNS fatigue and calcium-ion fatigue both serve the same function
- Why max effort and slow velocity don’t always equal max recruitment and max tension
- Programming implications: exercise order, rep ranges, RIR, clusters, and isometrics
What is Hypertrophy Past and Present?
A deep dive into the science of muscle growth. Hosted by Chris Beardsley and Jake Doleschal, this podcast explores hypertrophy training through the lens of pre-steroid era bodybuilding and modern muscle physiology.
