Summary
Meta-analysis found that adjusting training based on daily HRV readings leads to better performance outcomes than following predetermined training plans, particularly for endurance athletes.
Methods
Systematic review and meta-analysis of HRV-guided training studies
Key Findings
- HRV-guided training produced larger improvements in VO2max
- Athletes training on low-HRV days showed impaired adaptation
- Flexible programming based on HRV outperformed rigid periodization
- Benefits most pronounced in endurance sports
Limitations
Heterogeneous study designs, varying HRV thresholds used
What This Means for You
Listen to your HRV. If it's significantly below baseline, consider an easy day instead of pushing through a hard workout. This flexible approach produces better long-term gains than ignoring recovery signals.
