Age and sex differences in microvascular responses during reactive hyperaemia

Microvascular impairments are typical of several cardiovascular diseases. Near‐infrared spectroscopy (NIRS) combined with a vascular occlusion test provides non‐invasive insights into microvascular responses by monitoring skeletal muscle oxygenation …

Classification of Mild Cognitive Impairment Using Functional Near-Infrared Spectroscopy-Derived Biomarkers With Convolutional Neural Networks

Objective To date, early detection of mild cognitive impairment (MCI) has mainly depended on paper-based neuropsychological assessments. Recently, biomarkers for MCI detection have gained a lot of attention because of the low sensitivity of …

Cold-Water Immersion and Lower Limb Muscle Oxygen Consumption as Measured by Near-Infrared Spectroscopy in Trained Endurance Athletes

Context: Cold-water immersion (CWI) has been reported to reduce tissue metabolism postimmersion, but physiological data are lacking regarding the muscle metabolic response to its application. Near-infrared spectroscopy (NIRS) is a noninvasive optical …

Continuous blood flow restriction during repeated‐sprint exercise increases peripheral but not systemic physiological and perceptual demands

This study examined the impact of continuous blood flow restriction (BFR) during repeated‐sprint exercise (RSE) on acute performance, peripheral, systemic physiological, and perceptual responses. In a randomized crossover design, 26 adult male …

Effect of Interruptions and Cognitive Demand on Mental Workload: A Critical Review

Effects of a One-Day Experiential Sheep-Rearing Experience on Motivation, Anxiety, and Frontal Lobe Brain Activity in Patients with Chronic Psychiatric Disorders: A Crossover Pilot Study

The purpose of this study was to investigate the effects of a one-day sheep-rearing experience on motivation and anxiety levels in patients with chronic mental illness. The study assessed changes in oxytocin and cortisol levels and brain activity in …

Effects of endurance exercise on physiologic complexity of the hemodynamics in prefrontal cortex

Significance: Prefrontal cortex (PFC) hemodynamics are regulated by numerous underlying neurophysiological components over multiple temporal scales. The pattern of output signals, such as functional near-infrared spectroscopy fluctuations (i.e., …

Impaired muscle oxygenation despite normal pulmonary function in uncomplicated type 2 diabetes

Long-term hyperglycemia in individuals with type 2 diabetes can detrimentally impact pulmonary function and muscle oxygenation. As a result, these factors can impede the body's adaptation to physical exertion. We aimed to evaluate the oxygen pathway …

Mobile Near-Infrared Sensing - A Systematic Review on Devices, Data, Modeling and Applications

Mobile near-infrared sensing is becoming an increasingly important method in many research and industrial areas. To help consolidate progress in this area, we use the PRISMA guidelines to conduct a systematic review of mobile near-infrared sensing, …

Muscle Oxygen Extraction during Vascular Occlusion Test in Physically Very Active versus Inactive Healthy Men: A Comparative Study

An increase in the delivery and use of oxygen to the musculature in physically active subjects are determinants of improving health-related aerobic capacity. Additional health benefits, such as an increase in the muscle mass and a decrease in fat …

Neurocognitive effects a combined polyphenolic-rich herbal extract in healthy middle-aged adults – a randomised, double-blind, placebo-controlled study

Objective: This study assessed whether polyphenolic rich supplement containing Bacopa monnieri (BM: 300 mg), Panax quinquefolius ginseng (PQ: 100 mg) and whole coffee fruit extract (WCFE: 100 mg) could enhance cognitive performance, affect and …

Prefrontal Cortex Activity During Gait in People With Persistent Symptoms After Concussion

Background: Concussions result in transient symptoms stemming from a cortical metabolic energy crisis. Though this metabolic energy crisis typically resolves in a month, symptoms can persist for years. The symptomatic period is associated with gait …

Temporal Convolutional Network-Enhanced Real-Time Implicit Emotion Recognition with an Innovative Wearable fNIRS-EEG Dual-Modal System

Emotion recognition remains an intricate task at the crossroads of psychology and artificial intelligence, necessitating real-time, accurate discernment of implicit emotional states. Here, we introduce a pioneering wearable dual-modal device, …

The addition of blood flow restriction during resistance exercise does not increase prolonged low‐frequency force depression

At a given exercise intensity, blood flow restriction (BFR) reduces the volume of exercise required to impair post‐exercise neuromuscular function. Compared to traditional exercise, the time course of recovery is less clear. After strenuous exercise, …

The effect of cardiorespiratory fitness and habitual physical activity on cardiovascular responses to 2-hours of uninterrupted sitting

Prolonged uninterrupted sitting of textgreater3-hours has been shown to acutely cause central and peripheral cardiovascular dysfunction. However, individuals rarely sit uninterrupted for textgreater2-hours, and the cardiovascular response to this …

The relationship of problematic Facebook use and Facebook context on empathy for pain processing: A functional near-infrared spectroscopy study

Positive and negative consequences of using social media (SM) have been observed. Excessive use of SM, such as Facebook, can lead to problematic behaviours, resulting in emotional and social functioning changes. Moreover, the problematic use of SM is …

Tracking the Recovery of a Mild Traumatic Brain Injury Patient utilizing a 60 s Combined Functional Near-Infrared Spectroscopy and Psychomotor Testing Approach A Case Study

Identifying and tracking the recovery of patients with mild traumatic brain injuries (mTBI) has remained elusive due to the lack of non-invasive, objective neuroimaging techniques. The purpose of this case study was to provide a proof of concept for …
