Performance and Physiological Effects of Race Pace-Based versus Heart Rate Variability-Guided Training Prescription in Runners.

Purpose: The aim of the present study was to compare performance and physiological effects, and inter-individual response variation in performance and its physiological determinants between heart rate-based (HR), race pace-based (RP) and heart rate variability-based (HRV) training prescription approaches in recreational distance runners.

Methods: Twenty-eight participants completed a 6-week endurance training intervention after being randomly assigned to three groups: HR (n = 9), RP (n = 9), and HRV (n = 10) training prescription approaches.

Results: No interaction effects between groups were observed.
