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

Background Transcranial direct current stimulation (tDCS) has been used to improve
exercise performance, though the protocols used, and results found are mixed. Objective We …

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 This study investigated whether short-term heart rate variability (HRV) can be used
to differentiate between the immediate recovery periods following three different intensities …

Previous studies have neglected the first recovery minutes after exercise when studying post-
exercise heart rate variability (HRV). The present aim was to evaluate autonomic HR control …

The present study examined whether the ventilatory thresholds during an incremental
exhaustive running test could be determined using heart rate variability (HRV) analysis. Beat …

Exercise and training prescription in endurance-type sports has a strong theoretical
background with various practical applications based on threshold concepts. Given the …

Mobile health technologies can provide information routinely and on demand to manage
metabolic diseases (eg, diabetes and obesity) and optimize their treatment (eg, exercise or …

In mobile healthcare, heart rate variability (HRV) is increasingly being used in dynamic
patient states. In this situation, shortening of the measurement time is required. This study …
