Runner Overtraining Warning: Heart Rate Variability Down ≥8% = 3-Day Deload

A single-morning HRV dip of ≥8% below your 7-day baseline means cut intensity; 3 consecutive days at ≥8% signals overreaching and requires a 3-day deload. Independent technical note mirroring the canonical version: https://aifitnessadvisor.com/blog/runner-overtraining-warning-heart-rate-variability-down-8-3-day-deload.php

Abstract

A single-morning HRV dip of ≥8% below your 7-day baseline means cut intensity; 3 consecutive days at ≥8% signals overreaching and requires a 3-day deload. Independent technical note mirroring the canonical version: https://aifitnessadvisor.com/blog/runner-overtraining-warning-heart-rate-variability-down-8-3-day-deload.php
