INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is frequently associated with a reduced functional exercise performance. Even if this parameter is routinely evaluated using 6-minute walking test (6MWT), new field tests are regularly investigated as alternative tests. The aim of this study was to compare functional exercise performance evaluation by sit-to-stand test (STST) and 6MWT and to evaluate reliability and repeatability of the STST in COPD patients. METHOD: Forty-two COPD patients performed randomly two tests: 6MWT and STST...

BACKGROUND: At high altitude, prevalence of restless legs syndrome has been found to be greater than expected in small population-based studies, which did not use validated tools for identification of RLS. However, it is not known as to whether this increased prevalence is associated with altitude or increased risk factors for RLS in these populations or errors in identification of RLS. METHOD: This population based, door-to-door study was conducted at low altitude (400 m above sea level) and high altitudes (1900-2000 m and 3200 m above sea level) using random stratified sampling in Himalayan and sub-Himalayan region of India...

Cardiopulmonary exercise testing (CPET) aids in clinical assessment of patients with Fontan circulation. Effects of persistent fenestration on CPET variables have not been clearly defined. Associations between fenestration and CPET variables at anaerobic threshold (AT) and peak exercise were explored in the Pediatric Heart Network Fontan Cross-Sectional Study cohort. Fenestration patency was associated with a greater decrease in oxygen saturation from rest to peak exercise (fenestration -4.9 ± 3.8 v. nonfenestration -3 ± 3...

BACKGROUND: Adult patients with pulmonary arterial hypertension due to congenital heart disease (PAH-CHD) suffer from high mortality. This underlines the importance of adequate risk stratification to guide treatment decisions. Several baseline parameters are associated with mortality, however, their prognostic value may weaken after years of follow-up. Therefore we investigated the prognostic value of serial changes in standard clinical parameters in PAH-CHD. METHODS: In this prospective observational cohort study we included consecutive PAH-CHD adults, between 2005 and 2016...

Exposure to altitude results in multiple physiological consequences. These include, but are not limited to, a reduced maximal oxygen consumption, drop in arterial oxygen saturation, and increase in muscle metabolic perturbations at a fixed sub-maximal work rate. Exercise capacity during fixed work rate or incremental exercise and time-trial performance are also impaired at altitude relative to sea level. Recently, dietary nitrate (NO3(-)) supplementation has attracted considerable interest as a nutritional aid during altitude exposure...

Acute exercise-induced inflammation is implicated in mediating the beneficial adaptations to regular exercise. Evidence suggests that reduced oxygen and/or blood flow to contracting muscle alters cytokine appearance. However, the acute inflammatory responses to hypoxic/ischemic exercise have been documented with inconsistent results and may not accurately reflect the ischemia produced during exercise in patients with ischemic cardiovascular diseases. Therefore, we determined the extent to which local inflammation is involved in the response to ischemic exercise...

Previous studies in children and older adults demonstrated faster oxygen uptake (VO2) kinetics in males compared to females, but young health adults have not been studied. We hypothesized that young men would have faster aerobic system dynamics in response to the onset of exercise than women. Interactions between oxygen supply and utilization were characterized by the dynamics of VO2, deoxyhemoglobin (HHb), tissue saturation index (TSI), cardiac output (Q) and calculated arteriovenous O2 difference (a-vO2diff) in women and men...

INTRODUCTION: The Moxy is a novel, cutaneously placed muscle oxygen monitor which claims to measure local oxygen saturation (SmO2) and total haemoglobin (THb) using near-infrared spectroscopy. If shown to be reliable, its data storage and telemetric capability will be useful for assessing localised O2 usage during field-based exercise. This study investigated the reliability of the Moxy during cycling and assessed the correlations between its measurements, whole-body O2 consumption (VO2) and heart rate (HR)...

Blackcurrant is rich in anthocyanins that may affect exercise-induced physiological responses. We examined tissue oxygen saturation, muscle activity, cardiovascular responses and femoral artery diameter during a submaximal sustained isometric contraction. In a randomised, double-blind, crossover design, healthy men (n = 13, age: 25 ± 4 years, BMI: 25 ± 3 kg·m(-2), mean ± SD) ingested New Zealand blackcurrant (NZBC) extract (600 mg∙day(-1) CurraNZ™) or placebo (PL) for 7-days separated by 14-days washout...

Reducing the work of breathing or eliminating exercise-induced arterial hypoxemia (EIAH) during exercise decreases the severity of quadriceps fatigue in men. Women have a greater work of breathing during exercise, dedicate a greater fraction of whole-body V̇O2 towards their respiratory muscles, and demonstrate EIAH, suggesting women may be especially susceptible to quadriceps fatigue. Healthy subjects (8M, 8F) completed three constant load exercise tests over four days. During the first (control) test, subjects exercised at ∼85% of maximum while arterial blood gases and work of breathing were assessed...
