The HyPaultrophy podcast HOW cardio can kill your GAINZ
May 4, 2024
The podcast discusses how cardio can impact muscle gains, debunking myths about its direct impact on hypertrophy. It explores muscle fiber type shifting, muscle damage, and adaptation, emphasizing the importance of training close to failure for hypertrophy outcomes. The speakers also delve into calcium ion-related fatigue resistance, recovery strategies, optimizing muscle recovery and growth, and customizing cardio training for individual goals.

Episode notes
Interference Effect
- The "interference effect" is how aerobic exercise can hinder strength training adaptations.
- Recent research suggests muscle damage, not molecular signaling interference, is the primary cause.
Demand-Led Physiology
- Physiology operates on demand, not supply.
- Muscle fiber adaptations, including hypertrophy and capillarization, are responses to mechanical tension, not the other way around.
Cardio and Hypertrophy
- Cardio can cause hypertrophy in untrained individuals, particularly with eccentric loading.
- However, even short periods of strength training make it impossible to maintain muscle size with cardio alone.
