High-intensity interval training (HIT), in a variety of forms, is today one of the most effective
means of improving cardiorespiratory and metabolic function and, in turn, the physical …

The objective of exercise training is to initiate desirable physiological adaptations that
ultimately enhance physical work capacity. Optimal training prescription requires an …

Sleep is the most important period for recovery from daily load. Regular physical activity
enhances overall sleep quality, but the effects of acute exercise on sleep are not well …

Acute physical exercise may affect cardiac autonomic modulation hours or even days during
the recovery phase. Although sleep is an essential recovery period, the information on …

Heart rate variability (HRV) was assessed during the short-(within 1 h) and long-(within 48 h)
term recovery following a single bout of either constant (CST) or interval training (SWEET) …

This study compared subjective effort perception with objective physiological measures
during high-intensive intermittent exercise performed in normoxia, moderate hypoxia (FiO 2 …

Methodological problems have limited the number of studies on heart rate variability (HRV)
dynamics immediately after exercise. We used the short‐time Fourier transform method to …

The purpose of this study was to investigate the effect of exercise-induced plasma volume
expansion on post-exercise parasympathetic reactivation. Before (D 0) and 2 days after (D+ …

Purpose: To assess the effect of supramaximal intermittent exercise on long-term cardiac
autonomic activity, inferred from heart rate variability (HRV). Methods: Eleven healthy males …

We investigated performance and heart rate (HR) variability (HRV) over consecutive days of
cycling with post-exercise cold water immersion (CWI) or passive recovery (PAS). In a …
