When to Ignore Your HRV Score (And Why)

This week, I received an interesting question from Orson in Thailand about HRV monitoring.

After coaching fighters and analyzing performance data for over 15 years, I’ll share something counterintuitive:

Some of your best training sessions might happen on days when your HRV scores suggest otherwise.

Here’s what the research and practical experience shows:

Recovery Scores Are Signals, Not Stop Signs

  • Low HRV indicates an increased stress load
  • High HRV suggests parasympathetic dominance
  • Neither absolutely dictates training intensity

The Four-Week View

One of my fighters maintained peak performance while training through “red” HRV days during fight camp. Why? Because we:

  • Monitored weekly trends
  • Implemented strategic deload periods
  • Adjusted intensity based on the bigger picture

Individual HRV Response Patterns

  • Your baseline is unique,
  • Stress tolerance varies,
  • Adaptation rates differ

Practical Application: Monitor these instead of obsessing over daily HRV scores:

  • Performance metrics
  • Sleep quality
  • Training output
  • Recovery between sessions

Your Action Plan:

  • Record both HRV data and how you feel
  • Track 4-week training block responses
  • Assess recovery patterns post-deload
  • Adjust based on comprehensive data, not daily readings

During my fighting career, I often saw poor recovery scores during high-workload weeks.

Instead of backing off, we’d push through strategically, knowing the planned deload would allow for supercompensation.

The Science Supports This: Research shows that periodic high-stress training, followed by adequate recovery, creates superior adaptations compared to consistently moderate training.

Remember:

If you planned for a higher training stress this week, then don’t be worried if that’s what it looks like with your daily recovery scores!

Your body can handle more than your HRV sometimes suggests.

The key lies in managing the complete training cycle, not each individual session.
