Exploring heart rate variability as a biomarker for frailty: A narrative review

European Journal of Clinical Investigation, Volume 56, Issue 4, April 2026.
Frailty arises from progressive multisystem dysregulation, prompting interest in biomarkers that capture declining physiological reserve. This review positions heart rate variability (HRV) within this evolving biomarker landscape, outlining its physiological basis, analytical domains and relevance to clinical research.

Stress Physiology and HRV biofeedback in Adolescents with Autism

, 2023
In recent years, there has been an increased interest in identifying the role of aberrant stress regulation and anxiety in neuropsychiatric disorders, including autism spectrum disorder (ASD). In this context, increasing reports have emerged indicating a link between aberrant functioning of the autonomic nervous system (ANS), a central component of the

Photoplethysmography for Measuring Cognitive Load in XR Environments: A Systematic Review

Advanced Sensor Research, Volume 5, Issue 3, March 2026.
ABSTRACT Photoplethysmography (PPG) is a low‐cost, low‐power biosensing technology with growing applications in education, particularly for monitoring cognitive load in eXtended Reality (XR) learning environments. Measuring cognitive load is critical for preventing overload and optimising immersive learning, yet existing approaches such as self‐reports

User-Centred Design and Usability Evaluation of a Heart Rate Variability Biofeedback Game

IEEE Access, 2016
Reduced heart rate variability (HRV) is an indicator of a malfunctioning autonomic nervous system. Resonant frequency breathing is a potential non-invasive means of intervention for improving the balance of the autonomic nervous system and increasing HRV.

Effects of Biofeedback Training on Shooters' Performance, Stress Levels, and HRV

Journal of ASIAN Behavioural Studies
This study aimed to explore the impact of a 12-week biofeedback training on shooters' performance, stress levels, and heart rate variability (HRV). Thirty-six shooters aged 18-24 (18 subjects in each group) participated. The experimental group underwent 12 weeks of biofeedback and shooting training, while the control group only received shooting ...

Effects of Biofeedback Training on HRV, Mood State and Shooting Performance of Shooters

Environment-Behaviour Proceedings Journal
This study investigates the effects of biofeedback training on the HRV, emotional state, and shooting performance of athletes. Results indicate significant improvement in athletes' HRV frequency domain indices (p < 0.05), reduced negative emotions like tension and anger (p < 0.05), increased vitality and positivity, though changes in fatigue and ...

The Impact of Resonance Frequency Breathing on Measures of Heart Rate Variability, Blood Pressure, and Mood

Frontiers in Public Health, 2017
Heart rate variability biofeedback (HRVB) significantly improves heart rate variability (HRV). Breathing at resonance frequency (RF, approximately 6 breaths/min) constitutes a key part of HRVB training and is hypothesized to be a pathway through which ...
