Heart Rate Variability Alterations During Delayed-Onset Muscle Soreness-Inducing Exercise-With Piezo2 Interpretation.

ABSTRACT: Heart rate variability (HRV) is often modulated by pain; therefore, the objective of this study was to assess whether the induction of delayed-onset muscle soreness (DOMS) is already affected by HRV alterations during exercise, in spite of the fact that pain evolves only post-exercise. An isokinetic dynamometer was used to induce DOMS in this study on 19 young male elite handball players who were subjected to HRV measurements throughout a DOMS-inducing exercise session. The result of this study indicated that the heart rate (HR) dependence of time-frequency domain parameters could be described by an exponential-like function, while entropy showed a V-shaped function, with a minimum "turning point" separated by descending and ascending intervals. The DOMS protocol upshifted the time-frequen
