Summary
Large meta-analysis confirmed that regular exercise interventions improve HRV indices across diverse populations, with both aerobic and resistance training showing benefits.
Methods
Meta-analysis of exercise intervention studies up to November 2024
Key Findings
- Significant improvements in RMSSD and SDNN with exercise training
- Both aerobic and resistance training effective
- Benefits seen across age groups and fitness levels
- Effect size varies by baseline fitness and training type
Limitations
Exercise type, duration, and intensity varied widely across studies
What This Means for You
Any consistent exercise program will likely improve your HRV over time. You don't need a specific type—both cardio and strength training work. The key is consistency over weeks and months.
