040 This new study will change how you think about fatigue

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 routineA new “repetition duration” studyHow CNS fatigue and calcium-ion fatigue both serve the same functionWhy max effort and slow velocity don’t always equal max recruitment and max tensionProgramming implications: exercise order, rep ranges, RIR, clusters, and isometrics
