Physiological mechanisms underlying enhanced performance with blood flow restriction training: neuromuscular, vascular and metabolic adaptations

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated how 6 weeks of dynamic knee‐extensor interval training with blood flow restriction (BFR‐leg) and without (CTRL‐leg) impacts performance and its mechanisms using non‐invasive methods. Specifically, we used gold‐standard methods to assess neuromuscular function, vascular function using Doppler ultrasound, and near ...

An image-processing toolkit for remote photoplethysmography

Multimedia Tools and Applications
Abstract Objective. Image-processing-based remote photoplethysmography algorithms are usually composed of steps where different methods are used, and often, researchers perform these steps using methods that are not necessarily the best for their application.

How breathing disrupts vision: hyperventilation‐induced hypocapnia impairs oculomotor responses in resting humans

The Journal of Physiology, EarlyView.
Abstract figure legend Hypocapnic hyperventilation reduced end‐tidal carbon dioxide partial pressure and middle cerebral artery mean velocity, and impaired oculomotor response by modulating visual fixation and anti‐saccadic control. Hyperventilation itself also impaired anti‐saccadic control.

Burn wound classification model using spatial frequency-domain imaging and machine learning. [PDF]

, 2019
Accurate assessment of burn severity is critical for wound care and the course of treatment. Delays in classification translate to delays in burn management, increasing the risk of scarring and infection.

Imaging Photoplethysmography: a Real-time Signal Quality Index

Computing in Cardiology Conference (CinC), 2017
Imaging photoplethysmography (iPPG) is a promising technology for contactless heart rate (HR) monitoring. However iPPG signals are easily deteriorated by subject movements and illumination changes. The purpose of this study was to develop a signal quality index (SQI) for realtime HR monitoring applications and to assess its performance on a challenging

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Vasomotor assessment by camera-based photoplethysmography

Current Directions in Biomedical Engineering, 2016
Camera-based photoplethysmography (cbPPG) is a novel technique that allows the contactless acquisition of cardio-respiratory signals. Previous works on cbPPG most often focused on heart rate extraction.
