Associations between baseline autonomic function and recovery from hamstring delayed-onset muscle soreness

The purpose of this study was to assess the relationship between baseline heart rate variability (HRV) and bioelectrical phase angle and hamstring recovery at 72 and 96 h after a DOMS-inducing protocol in physically active men. Following experimentally induced hamstring DOMS in 46 physically active male participants aged 20.78 ± 2.19 years, recovery outcomes including maximal isometric strength, active knee extension range of motion (AROM), pressure pain threshold, and perceived soreness were evaluated at baseline and at 48, 72, and 96 h. Associations between baseline physiological markers and changes in recovery outcomes were subsequently examined using correlation analyses.

Statistical significance was set at p
