Cardiac parasympathetic activity may be non-invasively investigated using heart rate
variability (HRV), although HRV is not widely accepted to reflect sympathetic activity …

Endurance running has become an immensely popular sporting activity, with millions of
recreational runners around the world. Despite the great popularity of endurance running as …

The short-term scaling exponent alpha1 of detrended fluctuation analysis (DFA a1), a
nonlinear index of heart rate variability (HRV) based on fractal correlation properties, has …

Background Transcranial direct current stimulation (tDCS) has been used to improve

ABSTRACT NUNAN, D., G. DONOVAN, DG JAKOVLJEVIC, LD HODGES, GRH
SANDEROCK, and DA BRODIE. Validity and Reliability of Short-Term Heart-Rate Variability …

Background Exercise intensities are prescribed using specific intensity zones (moderate,
heavy, and severe) determined by a 'lower'and a 'higher'threshold. Typically, ventilatory (VT) …

The purpose of this study was to determine if changes in heart rate variability during
incremental exercise could be used to estimate lactate threshold and ventilatory threshold in …

Purpose The short-term scaling exponent alpha1 of detrended fluctuation analysis (DFA-a1)
of heart rate variability (HRV) has shown potential to delineate the first ventilatory threshold …

Past attempts to define an anaerobic threshold (AnT) have relied upon gas exchange
kinetics, lactate testing and field-based evaluations. DFA a1, an index of heart rate (HR) …
