A Novel method for quantifying fluctuations in wearable derived daily cardiovascular parameters across the menstrual cycle.

Currently, knowledge of changes in cardiovascular function across the menstrual cycle and how these changes may inform upon underlying health is limited. Utilizing wrist-worn biometric data we developed a novel measure to quantify and investigate the cardiovascular fluctuation (i.e.

Heart and Health Behavior Responses to GLP-1 Receptor Agonists: A 12-Week Study Using Wearable Technology and Causal Inference.

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) were originally developed for the treatment of type 2 diabetes but have recently been approved for chronic weight management and reducing cardiovascular risk in individuals with overweight and obesity. Despite this approval, significant heterogeneity in the cardioprotective benefits and less desirable increases in resting heart rate (RHR) with GLP-1 RAs have been reported. To better understand cardiovascular responses to GLP-1 RAs, and the potential role of health behaviors in influencing these responses, we leveraged wearable technology and causal inference analysis.

The Night-Time Sleep and Autonomic Activity of Male and Female Professional Road Cyclists Competing in the Tour de France and Tour de France Femmes.

Background: Sleep is a critical component of recovery, but it can be disrupted following prolonged endurance exercise. The objective of this study was to examine the capacity of male and female professional cyclists to recover between daily race stages while competing in the 2022 Tour de France and the 2022 Tour de France Femmes, respectively. The 17 participating cyclists (8 males from a single team and 9 females from two teams) wore a fitness tracker (WHOOP 4.

Wearable-derived maternal heart rate variability as a novel digital biomarker of preterm birth.

Despite considerable health consequences from preterm births, their incidence remains unchanged over recent decades, due partially to limited screening methods and limited use of extant methods. Wearable technology offers a novel, noninvasive, and acceptable way to track vital signs, such as maternal heart rate variability (mHRV). Previous research observed that mHRV declines throughout the first 33 weeks of gestation in term, singleton pregnancies, after which it improves.

Wearable derived cardiovascular responses to stressors in free-living conditions.

Stress contributes to the progression of many diseases. Despite stress' contribution towards disease, few methods for continuously measuring stress exist. We investigated if continuously measured cardiovascular signals from a wearable device can be used as markers of stress.
