This episode dismantles that myth with a deep dive into the science of the masters athlete. We reveal why the accepted 10-12% per decade decline in VO₂max is not inevitable; lifelong training can cut this rate in half by preserving stroke volume and oxygen extraction, even as maximal heart rate falls. You will learn the hard science behind "anabolic resistance"—the reason your muscles no longer respond to the same protein dose as a 20-year-old—and discover the elevated "Leucine Trigger" (3-4g per meal) required to activate the mTORC1 pathway for muscle repair. We also explore the neurological basis of sarcopenia, showing how heavy resistance training is the only proven method to prevent the denervation of fast-twitch (Type II) fibers and preserve your speed. This is your blueprint for longevity: learn the precise protein dose (35-40g per meal) to overcome metabolic blunting, why you must shift from Pyramidal to Polarized training to manage delayed autonomic recovery, and why popular longevity drugs like Metformin can actively sabotage your gains by blunting exercise adaptations.Keywords: masters athlete, aging, vo₂max, anabolic resistance, leucine trigger, type ii fibers, metformin, polarized training, menopause🎙️ Lactate, the podcast that deciphers science to improve your performance.Key references :Rogers, M.
