Purpose: The aim of this study was to investigate the effect of four weeks supplementation of   vitamin C on serum levels of total antioxidant capacity and malondialdehyde among inactive   men after an eccentric exercise.   Materials and Methods: Twenty non-athletic healthy volunteer men (24 ± 1.6 years old,   22.59 ± 2.62 body fat percentage and 48.96 ± 3.58 mL/kg/min maximum oxygen uptake) ...

Exercise capacity in patients with kidney failure undergoing dialysis is low compared with age-predicted values. The level of exercise tolerance in these patients is such that the energy requirements for activities of daily living and occupational tasks impinge on their capacity to perform these tasks. Therefore, it is not surprising that many patients do not seek or are unable to work because ...

BACKGROUND The ability of the Naughton-Balke exercise treadmill test, an objective indicator of exercise capacity, to predict abnormal hemodynamics and mortality in pulmonary hypertension is unknown. METHODS AND RESULTS We performed a cohort study of 603 patients with pulmonary hypertension from 1982 to 2006, and studied the utility of exercise treadmill test as a predictor of abnormal hemody...

Anginal perceptual threshold (the time from onset of 0.1 mV of ST segment depression to onset of angina during treadmill exercise) is prolonged in diabetic patients with coronary artery disease. In the present study, the functional significance of this perceptual abnormality was evaluated by analysis of its effect on exercise capacity and the severity of myocardial ischemia. Treadmill exercise ...

Heart rate variability (HRV) reflects the healthiness of autonomic nervous system, which is associated with exercise capacity. We therefore investigated whether HRV could predict the exercise capacity in the adults with cardiac syndrome X (CSX). A total of 238 subjects (57±12 years, 67.8% men), who were diagnosed as CSX by the positive exercise stress test and nearly normal coronary angiogram w...

abstract background: chronic obstructive pulmonary disease (copd) is currently the fourth cause of mortality worldwide. patients with copd experience periods of dyspnea, fatigue, and disability, which impact on their life. the objective of this study was to investigate the effect of short‑term inspiratory muscle training on exercise capacity, exertional dyspnea, and pulmonary lung function. mat...

Objective(s): We examined the effects of endurance exercise in the presence of Bunium persicum extract administration on lipid profile and cardiorespiratory capacity in hypercholesterolemic male mice. Materials and Methods: Forty male hypercholesterolemic mice were divided into four groups: Vehicle, Endurance exercise (EE), Bunium persicum extract (BPE), and EE + BPE. The exercise protocol was ...

Treadmill exercise capacity and symptomatic status were evaluated in 19 patients with hypertrophic cardiomyopathy while on placebo, low and high dosages of propranolol and low and high dosages of verapamil. Exercise duration on placebo was 6.1 ± 0.8 minutes. Verapamil administration improved exercise capacity by 26 ± 8% (1.6 ± 0.5 minutes; p < 0.005); propranolol improved exercise capacity by 2...

BACKGROUND Functional exercise capacity in people with asbestos related pleural disease (ARPD) is unknown and there are no data on health-related quality of life (HRQoL). The primary aims were to determine whether functional exercise capacity and HRQoL were reduced in people with ARPD. The secondary aim was to determine whether functional exercise capacity was related to peak exercise capacity,...
