Background: In sports medicine, near infrared spectroscopy (NIRS) is used to measure physiologic parameters of muscle function, and quantify the effects of exercise. Firstline treatment for urinary incontinence (UI) involves pelvic floor muscle (PFM) …

PURPOSE: This study aimed to assess and compare the systemic response of oxygen uptake kinetics and muscle deoxygenation between a 30-min rest protocol and a multivisit protocol on the parameters of the power-duration relationship (i.e., critical …

Lower-extremity peripheral artery disease (PAD) is associated with increased risk of cardiovascular events and impaired exercise tolerance. We have previously reported that leg heat therapy (HT) applied using liquid-circulating trousers perfused with …

Purpose: The current study sought to investigate the role of recovery intensity on the physiological and perceptual responses during cycling-based aerobic high-intensity interval training. Methods: Fourteen well-trained cyclists (V˙ O 2peak: 62 ± 9 …

Background: Chronic Kidney Disease (CKD) patients exhibit a reduced exercise capacity that impacts quality of life. Dietary nitrate supplementation has been shown to have favorable effects on exercise capacity in disease populations by reducing the …

High-Intensity Interval Exercise (HIIE) has been shown to be more effective than moderate-intensity exercise for increasing acute lipid oxidation and lowering blood lipids during exercise and postprandially. Exercise in cold environments is also …

This study examined acute effects of inspiratory resistive loading (IRL) during rest intervals on sprint interval exercise (SIE) performance. In a randomized crossover design, nine collegiate basketball players performed IRL (15 cmH2O) or passive …

PURPOSE: This study examined the issue of history-dependence on muscle excitation and oxygenation by using surface electromyography (EMG) and near-infrared spectroscopy (NIRS). METHODS: Eight male participants performed isometric knee extension force …

Altitude ascending represents an intriguing experimental model reproducing physiological and pathophysiological conditions sharing hypoxemia as the denominator. The aim of the present study was to investigate fractional oxygen extraction and blood …

Dark chocolate (DC) is high in flavonoids and has been shown to increase nitric oxide in the blood. Increased nitric oxide has the potential to improve delivery of oxygen to muscle, especially in hypoxic conditions, such as altitude. Our aim was to …

Background: Myofascial Reorganization (MFR) is a physiotherapy technique that mixes myofascial pressures and slips and has been used as a simple and non-invasive method that readjusts soft tissues, as well as myofascial adhesions and contractures …

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 …

International Journal of Exercise Science 13(3): 964-978, 2020. This study was designed to compare systemic O2 utilization (VȮ2), and changes in tissue O2 extraction [deoxyhemoglobin ($Δ$HHb)] in the vastus lateralis (VL), gastrocnemius (GAST) and …

We investigated the effects of: 1) Ischemic pre-conditioning (IPC) plus a concurrent five-day heat acclimation + IPC (IPC + HA), 2) five-day HA with sham IPC (HA), or 3) control (CON) on thermoneutral measurements of endurance performance, resting …

Changes in physical performance were assessed in response to two successive doubles badminton matches with implementation of ischemic pre-conditioning (IPC) or sham treatment during recovery period between matches. Eight French national team …

Objective: To explore measures of peripheral muscular oxygenation, coupled to gait characteristics, between preterm and full-term children during a 6-minute walking test (6MWT). Study design: Prepubescent children performed a 6MWT. During the test, …

Although acute hypoxia is of utmost pathophysiologic relevance in health and disease, studies on its effects on both the macro- and microcirculation are scarce. Herein, we provide a comprehensive analysis of the effects of acute normobaric hypoxia on …

Optimizing traditional training methods to elicit greater adaptations is paramount for athletes. Ischemic preconditioning (IPC) can improve maximal exercise capacity and up-regulate signaling pathways involved in physiological training adaptations. …

Muscle oxygenation (MO) status is the dynamic balance between O2 utilization and O2 delivery. Low-impact high-intensity interval exercise MO responses in the exercise and recovery stage are still unclear. We compared the differences in MO and …

The purpose of this study was to review acute physiological responses induced by repeated running sprint ability (RRSA) tests that could serve as references for practitioners utilising repeated sprints as a performance measure with athletes. This …
