Background Cardiac autonomic neuropathy is a common complication of type 2 diabetes
mellitus (T2DM), that can be measured through heart rate variability (HRV)–known to be …

Orthostatic testing, involving the transition from different body positions (eg, from lying or
sitting position to an upright or standing position), offers valuable insights into the autonomic …

The present study sought to expand upon prior investigations of the relationship between
post-exercise heart rate recovery (HRR) and cardiovagal resting-reactivity modulation. HRR …

Wearable health devices (WHDs) are rapidly gaining ground in the biomedical field due to
their ability to monitor the individual physiological state in everyday life scenarios, while …

Any reliable biomarker has to be specific, generalizable, and reproducible across
individuals and contexts. The exact values of such a biomarker must represent similar health …

Background To examine the effects of varying doses of caffeine on autonomic reactivation
following anaerobic exercise. Methods Recreationally active males (N= 20; 24±2y) …

The present study was designed to investigate the effects of different caffeine dietary
strategies to compare the impact on athletic performance and cardiac autonomic response …

Short-term ECG-derived heart rate variability can assess autonomic function non-invasively.
The purpose of this study is to investigate the influence of body posture and gender on …

Purpose This study tested the hypothesis that prepubertal boys, but not untrained men,
would exhibit a similar post-exercise parasympathetic reactivation as well-trained adult male …

Many intervention studies assume the stability of heart rate variability (HRV) parameters,
and their sample sizes are often small, which can significantly affect their conclusions. The …
