Peripheral muscle oxygenation and symptoms of stress in adolescents with and without temporomandibular disorder.

Published in Clinical oral investigations

To compare peripheral muscle oxygenation levels and the prevalence of psychological stress in adolescents with and without temporomandibular disorder (TMD). A cross-sectional study was performed with adolescents submitted into two groups: those diagnosed with TMD (DG) and control (CG). Muscle oxygenation was measured by near-infrared spectroscopy i...

Agreement between multiparametric MRI (PIVOT), Doppler ultrasound, and near-infrared spectroscopy-based assessments of s...

Published in Magnetic resonance imaging

Skeletal muscle perfusion and oxygenation are commonly evaluated using Doppler ultrasound and near-infrared spectroscopy (NIRS) techniques. However, a recently developed magnetic resonance imaging (MRI) sequence, termed PIVOT, permits the simultaneous collection of skeletal muscle perfusion and T2* (an index of skeletal muscle oxygenation). To dete...

Effects of the exercise training on skeletal muscle oxygen consumption in heart failure patients with reduced ejection f...

Published in International journal of cardiology

Skeletal muscle dysfunction is a systemic consequence of heart failure (HF) that correlates with functional capacity. However, the impairment within the skeletal muscle is not well established. We investigated the effect of exercise training on peripheral muscular performance and oxygenation in HF patients. HF patients with ejection fraction ≤40% w...

Évaluation des réponses respiratoires, musculaires et perceptuelles lors d'un test d'aptitude aérobie chez le jeune en s...

L'optimisation des bénéfices d'un programme d'activité physique adaptée sur l'aptitude aérobie est conditionnée par la capacité du test à mesurer et détecter les changements dans les paramètres que l'on souhaite investiguer, qui sont principalement la vitesse maximale aérobie (VMA) et la consommation maximale en oxygène (VO₂max). Or, les jeunes en ...

The Use of Near Infrared Spectroscopy to Evaluate the Effect of Exercise on Peripheral Muscle Oxygenation in Patients wi...

OBJECTIVE: Near infrared spectroscopy (NIRS) has been suggested as a new diagnostic tool in patients with lower extremity artery disease (LEAD). The aim of this systematic review was to summarise the impact of exercise therapy on lower limb muscle oxygenation, evaluated by NIRS, in patients with LEAD, and to give an overview on NIRS instruments and...

Reduced Scattering Coefficient During Incremental Exercise Is Constant Without Being Affected by Changes in Muscle Oxyge...

Published in Advances in experimental medicine and biology

Previous studies have reported that the reduced scattering coefficient (μs') in the vastus lateralis changes during ramp-incremental exercise due to blood volume changes or accumulation of metabolic by-products. We aimed to clarify the influences of deoxygenation and blood volume changes during exercise on μs' dynamics in subjects with various aero...

Rolling massage acutely improves skeletal muscle oxygenation and parameters associated with microvascular reactivity: Th...

Published in Microvascular research

Although it has been claimed that rolling massage (RM), may lead to improvements in skeletal muscle oxygenation, metabolism, blood flow, and vascular function, scientific evidence has not yet been provided. Thus, the current study investigated the effects of 30 s and 2 min of RM on forearm muscle oxygenation, parameters associated with oxidative me...

Effects of 21 days of bed rest and whey protein supplementation on plantar flexor muscle fatigue resistance during repea...

Published in European journal of applied physiology

Space flight and bed rest (BR) lead to a rapid decline in exercise capacity. Whey protein plus potassium bicarbonate diet-supplementation (NUTR) could attenuate this effect by improving oxidative metabolism. We evaluated the impact of 21-day BR and NUTR on fatigue resistance of plantar flexor muscles (PF) during repeated shortening contractions, an...

Muscle Oxygen Demands of the Vastus Lateralis in Back and Front Squats

Published in International Journal of Exercise Science

In resistance training squats are often used to strengthen the muscles of the lower extremities and core muscles. There are two common forms of squats that use a barbell for loading, the back squat and the front squat. The technique and loading of each squat differ markedly. However, the energetic demands on the muscle between the two forms are not...
