Reproducibility of the RMSSD Index of Heart Rate Variability in Recovery After Exercise

Heart rate variability (HRV) is an important parameter that allows evaluate parasympathetic reactivation after physical exercise. However, because its a cardiac phenomenon evaluated in non-stationary conditions, it is fundamental to evaluate its reproducibility in post exercise recovery. PURPOSE: To analyze whether the RMSSD index of HRV shows reproducibility in both passive and active after maximal exercise recovery. METODOLOGY: Eleven young...
