The effects of an ultra-endurance event on heart rate variability and cognitive performance during induced stress in Ironman triathletes

, 2009
Includes abstract.Includes bibliographical references (leaves 55-79).The effects of long-term participation in ultra-endurance exercise on the cardiovascular system have recently been the subject of much interest.

Effects of reducing sedentary behaviour on heart rate variability and cardio‐metabolic biomarkers in desk workers with untreated high blood pressure

Experimental Physiology, EarlyView.
Abstract Lower sedentary behaviour (SB) has been associated with reduced cardiovascular disease and mortality. Yet, few trials have evaluated cardiovascular mechanisms of benefit. We examined the effects of a SB reduction intervention on heart rate variability (HRV) and cardio‐metabolic biomarkers.

Influence of oestradiol on exercise induced muscular damage and heart rate variability in a non‐trained healthy population

Experimental Physiology, EarlyView.
Abstract This study evaluates in non‐trained healthy women the influence of oestradiol (E2) on exercise induced muscular damage (EIMD) and performance. Thirty‐six young healthy women performed a step‐exercise until exhaustion, assessing the number of repetitions, pain perception and well‐being (questionnaires, 15 min and at 48 h post‐exercise), blood ...

A wireless transmission system for real-time detection of HRV signals

, 2010
碩士近年來，心律變異性（Heart rate variability，HRV），一直是相當熱門的研究，在諸多非侵入式量測的生理信號中，是最常使用的，也最具有參考價值，而無線感測網路Zigbee之技術相當成熟，其應用也相當多，從保全系統、醫療系統、自動化系統等等，其技術擁有低成本、低耗電可應用於長時間監控。 本論文主要目的，是將HRV訊號應用於Zigbee無線傳輸系統，使HRV與Zigbee做結合，改變目前測試方式，將有線系統轉換成無線系統，以克服環境上之限制 ...

Advancing tele‐physiology: A chest patch solution for continuous, non‐invasive remote monitoring in a hypoxic environment

Experimental Physiology, EarlyView.
Abstract Skin‐mounted sensors are thin, flexible and lightweight electronic devices that enable monitoring of multiple physiological parameters. The aim of this study was to provide pilot evidence for possible utilization of a sensorized patch for capturing the bodily response to hypoxia. The subsequent phases of the study comprised a case report and a

Dose‐dependent effects of graded altered gravity during hypovolaemia on central haemodynamics and cardiovascular autonomic regulation

Experimental Physiology, EarlyView.
Abstract The cardiovascular system is strongly influenced by gravitational loading and blood volume status. Quantifying central haemodynamic and autonomic reflex responses to fluid redistribution is important in altered‐gravity conditions, with relevance to spaceflight and clinical medicine.

Sleep Apnea and Paroxysmal Atrial Fibrillation: Diurnal Patterning of Autonomic Dysfunction and Influence of CPAP Therapy. [PDF]

J Arrhythm
Autonomic dysfunction in sleep apnea shows diurnal variation, with stronger associations between SDB severity and HRV during wakefulness than sleep. CPAP therapy induces complex, state‐dependent changes in HRV, suggesting that daytime autonomic alterations may better reflect sustained cardiovascular risk in patients with paroxysmal atrial fibrillation.
