Objectives: To use a quantitative approach to examine the effects of high-intensity interval
training (HIIT) interventions on sleep for adults. Methods: PubMed, Ebsco, Web of Science …

The study aimed to determine if overnight heart rate variability (HRV) is reflective of
workload and stress during military training. Measures of cognitive load, perceived exertion …

Previous studies have explored the effect of differing heat and relative humidity (RH)
environments on the performance of multiple anaerobic high-intensity interval training (HIIT) …

Purpose: Heart rate variability (HRV) has gained acceptance as a key marker of
cardiovascular health. We compared HRV responses after continuous moderate-intensity …

Background Depression is closely linked to an imbalance in the autonomic nervous system
(ANS). However, the role of this imbalance in mediating the effects of sleep deprivation (SD) …

Objective Physical exercise—especially at high intensity—is known to impose cardiac
stress, as mirrored by, eg, increased blood levels of cardiac stress biomarkers such as …

Introduction: High-intensity interval exercise (HIIE) is deemed effective for cardiovascular
and autonomic nervous system (ANS) health-related benefits, while ANS disturbance …

Introduction: The maximal rate of oxygen consumption is the gold standard when
determining cardiorespiratory fitness (CF) in healthy and diseased populations. CF has …

Collegiate rowing performance is often assessed by a cardiopulmonary exercise test
(CPET). Rowers' on-water performance involves non-linear dynamic interactions and …

People practicing high-intensity interval exercise (HIIE) fasted during the morning hours
under a lack of sleep. Such a habit may jeopardize the health benefits related to HIIE and …
