High-Intensity Training & HRV (N=1 Data)
High-intensity training blocks suppress HRV acutely (especially without rest weeks), with recovery during reduced training periods.
N=1 Evidence
- MattS: Triathlon training ramp to 10 hrs/wk, no rest weeks → HRV decreasing
- Jbhkhc: TrainerRoad Short Power Build ~8 weeks post-COVID
- oggie41: First race of season; daily HRV tracked
Pattern: HRV declines during high training load, recovers with rest.
