Stephen Seiler
Dr. Stephen Seiler is a pioneering exercise physiologist known for his groundbreaking research in endurance sports and the polarized training model. He discusses the 80/20 training model, emphasizing low-intensity training for endurance enhancement and lactate reduction. The conversation dives into the physiological mechanisms that allow athletes to cycle faster at lower heart rates, introducing concepts like Zone 2 training and 'green zone' training for optimal recovery. Dr. Seiler also explores the significance of ventilation measurements over traditional lactate testing for better training metrics.

Episode notes
INSIGHT

Oxygen Delivery And Mitochondria Limit Endurance

  • Endurance limits are about oxygen delivery and muscle mitochondria capacity.
  • More mitochondria and capillaries let you oxidize fat and avoid fatigue-causing byproducts.
INSIGHT

Training Shifts Lactate Profile Right And Down

  • When athletes train more low-intensity work, lactate profiles both shift right and drop down.
  • That makes cruising speeds metabolically cheaper across intensities.
ADVICE

Prioritize Low-Intensity Sessions

  • Do most sessions at low intensity because recovery is faster and stress cost is low.
  • Keep green-zone work frequent so you can train daily on a 24-hour recovery clock.
