Purpose: Increasing prevalence of oral contraceptive (OC) use in physically active females highlights the need for sex-specific exercise metabolism research. This pilot study investigated the influence of chronic OC use on the exercising metabolic …

Following an acute infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a substantial percentage of patients report the persistence of debilitating symptoms, often grouped in a syndrome termed ‘long COVID’. We sought to …

Background Non-invasive determination of mitochondrial capacity via near infrared spectroscopy (NIRS) typically involves voluntary exercise of a single muscle group followed by as many as 26 brief ischemic cuff occlusions to determine a single …

We sought to investigate if critical oxygenation (COx) is a robust marker of exercise intensity, and if it remains stable in normoxia and hypoxia with simultaneous changes in critical power (CP) and heart rate (HR).Thirty-three highly trained …

Introduction Vascular dysfunction is a hallmark of chronic kidney disease (CKD), with previous studies showing progressively deteriorating microvascular reactivity in skeletal muscles with advancing CKD stages. Additionally, cognitive impairment is …

Aims Emerging evidence suggests Type 2 diabetes (T2D) may adversely affect cerebral hemodynamics and oxygenation. This study aimed to explore the impact of uncomplicated T2D on cerebral hemodynamics and oxygenation during maximal exercise. Methods In …

Objective: To investigate the agonist and antagonist muscles implication during a prolonged trunk extension exercise and to determine the relationship with paraspinal muscle metabolic and hemodynamic responses in healthy individuals. Methods: Sixteen …

Purpose: To examine the effect of repeated-sprint training in hypoxia (RSH) on oxygenation kinetics in the vastus lateralis muscle using statistical parametric mapping during repeated treadmill sprints in world-class female Rugby Sevens players. …

This investigation examined a moderate individualized pressure (i.e., percentage of total arterial occlusion pressure [TAOP]) compared to low and high absolute pressures on muscle tissue oxygenation (StO2) throughout ischemic preconditioning (IPC). …

Lower limb exoskeletons have been designed to assist human walking. However, current unpowered exoskeletons primarily targeted the ankle joint, but neglected the energy storage and recoil within the foot. In this study, we proposed an unpowered …

Manipulation of the mouse gut microbiome has been shown to increase gut-derived short-chain fatty acids and improve exercise capacity. Associations between exercise performance and gut microbiome composition and metabolites have also been identified …

Purpose Near-infrared spectroscopy (NIRS) can be applied to assess skeletal muscle oxidative capacity (mV˙O2). Specific force (SF) and echo intensity (EI) represent muscle quality. However, it is unknown how exercise participation and biological sex …

Ischemic preconditioning (IPC) is a potential ergogenic technique but the response rates vary considerably in the literature. The use of markedly different IPC protocols among the published literature, including pressure, rounds of ischemia, and time …

This chapter delves into the critical role of oxygen metabolism in skeletal muscles during dynamic exercise, emphasizing the importance of efficient oxygen supply to sustain muscle activity, particularly during high-intensity efforts. The study …

Purpose: This study examined differences in metrics of skeletal muscle re-saturation between strength and aerobically oriented individuals and potential relations between re-saturation and aerobic fitness. Methods: Forty-nine healthy young adult men …

The purpose of this study was to examine how the work rate (WR) influences whole-body metabolic rate (MR) and more local measures of intensity (i.e., pole power, joint power, and triceps brachii (TB) and vastus lateralis (VL) tissue saturation index …

Introduction This study investigated the effects of body weight (BW) reduction and hypoxia on physiological and perceptual responses during high-intensity interval exercise (HIIE) on the anti-gravity AlterG® treadmill. Material & methods Twenty-six …

Antecedentes y objetivo. El entrenamiento muscular inspiratorio (EMI) genera efectos positivos en el rendimiento físico, pero existen pocas pruebas sobre los efectos en la resaturación muscular en adultos mayores. El objetivo del estudio fue evaluar …

Introduction: Implanted spinal cord epidural stimulation (SCES) is an emerging neuromodulation approach that increases the excitability of the central pattern generator [CPG] and enhances tonic and rhythmic motor patterns after spinal cord injury …

Heart rate (HR) and heart rate variability (HRV) are established measures related to cardiovascular disease (CVD), a known risk factor correlated with lower urinary tract symptoms (LUTS) and overactive bladder (OAB). However, no standardized …
