Oxygen uptake efficiency slope (OUES) and ventilatory efficiency (VE/VCO2 slope) are widely used as submaximal measurements of cardiopulmonary exercise testing as the evaluator or prognosticator of cardiac diseases. However, very few studies have compared the effects of submaximal exercise on these measurements. A total of 58 patients with coronary artery disease underwent maximal cardiopulmona...

Some recent studies of competitive athletes have shown exercise-induced hypoxemia to begin in submaximal exercise. We examined the role of ventilatory factors in the submaximal exercise gas exchange disturbance (GED) of healthy men involved in regular work-related exercise but not in competitive activities. From the 38 national mountain rescue workers evaluated (36 +/- 1 yr), 14 were classified...

Right ventricular function was assessed in 24 patients with COPD, at rest and during submaximal exercise, using both technetium-99m (99mTc) blood-pool and krypton-81m (81mKr) equilibrium ventriculography. Technetium-99m right ventricular ejection fraction (RVEF) at rest was lower than 81mKr RVEF (0.39 +/- 0.12 and 0.54 +/- 0.08, respectively; p < 0.001). During submaximal exercise, there was no...

the aim of this study was to investigate the effect of 12 weeks moderate intensity aerobic exercise on leptin and c-reactive protein serum levels in obese men. the study was conducted in urmia- iran in 2015. twenty-four obese men with an aged range 40-50 yrs. were enrolled into the study. subjects were randomized to one of 2 groups exercise (n=12) and control groups (n=12). the exercise group p...

the aim of this study was to compare the effect of an aerobic exercise program with two different volumes on some risk factors of cardiovascular diseases in mentally retarded girls. 24 mentally retarded girls were randomly assigned to three groups: 1) aerobic exercise, 3 sessions per week for 45 minutes, 2) aerobic exercise, 4 sessions per week for 40 minutes, and 3) control. the experimental g...

background: pulmonary complications, respiratory symptoms and depression are common occurrences which contribute to the morbidity and mortality seen in individuals living with hiv/aids. this study investigated the effect of aerobic exercise on the pulmonary functions, respiratory symptoms and psychological status of people living with hiv. methods: this study was conducted in lagos, nigeria fro...

objective(s)apelin is novel adipokine acting on apj receptor, regulated by insulin and tumor necrosis factor-alpha (tnf-alpha). plasma apelin levels are increased in obese subjects. the aim of this study was to investigate whether or not the aerobic exercise modifies the elevated plasma apelin levels in obese women.materials and methodstwenty obese women (bmi 32.2 ± 6.4 kg/m2) were selected by ...
