Episode Details

I explain how understanding and training your autonomic system transforms how you approach effort, recovery, and race-day control. You’ll learn the physiological mechanisms behind performance control, and practical ways to measure and improve your system’s readiness using research-backed tools.

What You’ll Learn

  • How the autonomic nervous system fits within the central nervous system and acts as your internal performance regulator.
  • The difference between the sympathetic and parasympathetic branches, and how smooth transitions between them underpin endurance control.
  • Why “sympathetic dominance” creates hidden fatigue and how to recognise its early signs.
  • The science behind vagal tone and neurovisceral integration, and why it’s a key marker of resilience and recovery.
  • Credible methods to assess autonomic readiness using the Polar H10 or Garmin HRM Pro Plus with the Elite HRV app, and why wrist-based sensors are unreliable for HRV.
  • How to apply HRV data to training decisions: knowing when to push intensity and when to focus on technique or recovery.
  • How to regulate during sessions with 4:6 breathing patterns to stabilise the nervous system.
  • Why 45–60 seconds of deliberate exhalation post-training accelerates recovery and improves vagal response.
  • How autonomic mastery allows calm aggression in racing, activation without anxiety.

Key Takeaways

  • The autonomic nervous system decides how efficiently you can access your fitness, not just how hard you train.
  • True performance control comes from transitioning smoothly between activation and recovery, not staying stuck in one state.
  • HRV data is valuable only when measured accurately with ECG-grade sensors — not wrist-based estimates.
  • Use HRV trends to align effort with readiness instead of emotion.
  • Breathing control isn’t relaxation, it’s precision regulation for faster recovery and sharper focus.
  • Training smarter means managing your system, not just your schedule.

Work With Me

The off-season is where mental performance is built.

If you’re ready to strengthen the system that drives every part of your performance, your mind and nervous system, this is the time to begin.

My Performance Program integrates neuroscience, psychology, and endurance principles to help you:

  • Understand your physiological readiness.
  • Build mental structures that hold under fatigue.
  • Develop composure, clarity, and pacing control that last all season.
