Muscle mitochondrial capacity in high‐ and low‐fitness females using near‐infrared spectroscopy

The recovery of muscle oxygen consumption (m (Formula presented.) O2) after exercise measured using near-infrared spectroscopy (NIRS) provides a measure of skeletal muscle mitochondrial capacity. Nevertheless, due to sex differences in factors that …

Exploring the brain activity related to missing penalty kicks: an fNIRS study

Despite having a near perfect control over a ball, professional football/soccer players often miss penalties. Psychological factors (anxiety) are often named as explanations for these misses. A commonly used terminology is 'choking under pressure'. …

Using Functional Near-Infrared Spectroscopy to Detect a Fear of Heights Response to a Virtual Reality Environment

Over the past decades, virtual reality (VR) technology has gained significant popularity and interest, both in research as well as on the consumer market. One promising application area of VR is virtual reality exposure therapy (VRET), which treats …

The Optimal Treatment Time Of Dry Cupping Therapy To Induce Changes In Local Blood Flow At The Upper Trapezius

Context: Musculoskeletal neck and shoulder pain is a prevalent condition with nearly two-thirds of the population experiencing it sometime in their lifespan; factors may include activity level, sex, stress, and postural deficits. The treatment …

DESIGN AND EVALUATION OF A GUI FOR SIGNAL AND DATA ANALYSIS OF MOBILE FUNCTIONAL NEAR-INFRARED SPECTROSCOPY SYSTEMS A Thesis by

Functional near-infrared spectroscopy (fNIRS) is an emerging neuro-imaging modality that can indicate cortical functionality with good temporal resolution (0.5-1 sec). Unlike fMRI, up to now, there is no standard method and a whole package that can …

Differential Control of Muscle Sympathetic Single-Unit Activity in Humans

Background: The sympathetic nervous system plays a critical role in blood pressure regulation at rest and during stress. Sympathetic neural activity directed towards skeletal muscle constricts the vasculature to raise resistance within the arterial …

Role of exercise, cold, and the biological clock on energy balance in humans: The ACTIBATE study

Cold exposure has been proposed as a potential tool to face obesitysince it is able to increase energy expenditure (i.e., cold induced thermogenesis –CIT). This increase is partially mediated by brown adipose tissue (BAT). Nevertheless, little is …

The Use of NIRS in Monitoring Lower-Limb Motor Activation: A Study Comparing a Mobile and Research-Grade System

Predicting the binding mode of flexible polypeptides to proteins is an important task that falls outside the domain of applicability of most small molecule and protein−protein docking tools. Here, we test the small molecule flexible ligand docking …

Thesis The Voice of Primates : Neuro-evolutionary Aspects of Emotions NEURO-EVOLUTIONARY ASPECTS OF EMOTIONS

Rightly emphasized by Pascal Belin “Voices are everywhere”. From music to social conversation, the human voice has indeed the extraordinary power to communicate our everyday emotions. Shaped by millions of years of evolution, the vocal recognition of …

A mini-review on functional near-infrared spectroscopy (fNIRS): Where do we stand, and where should we go?

This mini-review is aimed at briefly summarizing the present status of functional near-infrared spectroscopy (fNIRS) and predicting where the technique should go in the next decade. This mini-review quotes 33 articles on the different fNIRS basics …

Effectiveness of 6-Ischemic Cuff Near Infrared Spectroscopy Mitochondrial Capactity Test

Near-Infrared Spectroscopy (NIRS) has been used to measure muscle mitochondrial capacity. The current method requires as many as 22 short ischemic occlusions to generate a recovery curve for mitochondrial capacity. PURPOSE: To determine the …

Optic nerve hypoplasia

Optic nerve hypoplasia is a congenital anomaly in which the optic disc is abnormally small and is associated with other neurodevelopmental disorders. Optical coherence tomography (OCT) can be used to measure the retinal nerve fiber layer and can add …

An Investigation into the Effect of Skeletal Muscle Metabolic Function & Cardio-Respiratory Fitness on Exercise Capacity in the Presence and Absence of Disease

It is uncommon for cardio-respiratory fitness and skeletal muscle metabolic function to be assessed independently within an exercise test. Exercise capacity may require adaptation of one or other of these systems to a greater or lesser extent and the …

Effects of Aerobic Exercise on Cognitive and Cerebrovascular Function in Hypertensive Adults

The presence of hypertension in middle-age is a major risk factor for later-life development of cognitive and cardiovascular disease. Exercise is widely recommended to combat vascular and brain aging in hypertension. We sought to compare the effects …

Impact of Prolonged Sitting on Cognitive Function : Implications for Cardio-metabolic Risk

Purpose: To determine if prolonged sitting negatively impacts cognitive function, cerebral perfusion, and central cardiovascular hemodynamics; and secondly, to test whether weight or physical activity status alters this response. Methods: …

Oxygen Delivery and Utilization During Acute Dynamic Exercise

Background and aims Polycystic ovary syndrome (PCOS) and type 1 diabetes are relatively common endocrinopathies, often manifesting across most of the lifespan. Cardiovascular risk is increased in both PCOS and type 1 diabetes, affecting patients' …

P77 Near Infrared Spectroscopy (Nirs) Can Detect Differences in Microvascular Reactive Hyperaemia in the Presence of Hypertension

Background: Hypertension has adverse effects on microvascular function but there are limited methods that permit non-invasive assessment of the microcirculation in man in vivo. We used Near Infrared Spectroscopy (NIRS) to assess microvascular …

THE IMMEDIATE AND EXTENDED EFFECT OF DIET AND EXERCISE ON METABOLIC FLEXIBILTY A Dissertation Louisiana State University and Agricultural and Mechanical College in partial fulfillment of the requirements for the degree of Doctor of Philosophy in The Schoo

Metabolic inflexibility is an emerging physiological marker indicative of metabolic dysfunction and associated with type 2 diabetes (T2D) and obesity. Exercise is a potent stimulus to improve metabolic health, however, not much is known about the …

Near-infrared spectroscopy and skeletal muscle oxidative function in vivo in health and disease: a review from an exercise physiology perspective

In most daily activities related to work or leisure, the energy for muscle work substantially comes from oxidative metabolism. Functional limitations or impairments of this metabolism can significantly affect exercise tolerance and performance. As a …
