Researchers have increasingly begun to use consumer wearables or wrist-worn
smartwatches and fitness monitors for measurement of cardiovascular psychophysiological …

The availability of wearable devices (WDs) to collect biometric information and their use
during activities of daily living is significantly increasing in the general population. These …

Smart wearables provide an opportunity to monitor health in daily life and are emerging as
potential tools for detecting cardiovascular disease (CVD). Wearables such as fitness bands …

Background: The associations of frailty with the risk of mortality and resource utilization in
the elderly patients admitted to intensive care unit (ICU) remain unclear. To address these …

Heart rate (HR) responds to exercise by increasing during exercise and recovering after
exercise. As such, HR is an important predictor of mortality that researchers believe is …

The long-term sequelae of coronavirus disease 2019 (COVID-19) are only now beginning to
be defined, but it is already known that the disease can have direct and indirect impacts …

The aim of this study was to identify the relationship between health‐related physical fitness
components (aerobic fitness, muscle strength, flexibility, and body fat) and resting heart rate …

Purpose: This systematic review with meta-analysis was conducted to establish whether
heart rate variability (HRV)-guided training enhances cardiac-vagal modulation, aerobic …

Problems with fatigue and sleep are highly prevalent in patients with chronic diseases and
often rated among the most disabling symptoms, impairing their activities of daily living and …

Heart rate variability (HRV), blood pressure variability (BPV), and baroreflex sensitivity
(BRS) provide important information on cardiovascular autonomic control. However, little is …
