WebOct 1, 2013 · 1. Introduction. Heart rate variability (HRV) describes the variations between consecutive heartbeats, known as R–R intervals. These interval regulation mechanisms are originated from the sympathetic and parasympathetic nervous systems and, thus, HRV can be used as a quantitative marker of the cardiac autonomic nervous system (ANS) … WebJan 15, 2024 · The short-term scaling exponent alpha1 of detrended fluctuation analysis (DFA a1), a nonlinear index of heart rate …
WebThe short-term scaling exponent alpha 1 of detrended Fluctuation Analysis (DFA-α1) of the Heart Rate Variability (HRV) has been proposed as a non-invasive methodology to detect intensity thresholds. Purpose: The aim of this study is to analyse the validity of DFA-α1 HRV analysis to determine the individual training thresholds in elite ...
