PURPOSE The purpose of this study was to investigate the oxidative stress response to a short duration bout of submaximal exercise in a cohort of healthy young adults. METHODS 15 apparently healthy college age males and females completed a modified Bruce-protocol treadmill test to 75-80% of their heart rate reserve. Blood samples collected immediately before (pre-exercise), immediately after,...
OBJECTIVES To investigate the physiological effects of two different three times a week, eight week training programmes on the aerobic fitness of nine to ten year old girls. METHODS Treadmill determined peak VO2, submaximal heart rates, and submaximal blood lactate were the criterion measures. Seventeen girls completed a programme of "aerobics" training where sessions lasted 20-25 minutes. Ei...
Compared with maximal exercise testing, submaximal exercise testing appears to have greater applicability to physical therapists in their role as clinical exercise specialists. This review contrasts maximal and submaximal exercise testing. Two major categories of submaximal tests (ie, predictive and performance tests) and their relative merits are described. Predictive tests are submaximal test...
Introduction: Effects of exercise on different body systems, especially cardiovascular and musculoskeletal systems are evidenced. There is a dynamic homeostatic balance between coagulation and fibrinolysis in normal circulation. Effect of exercise and training on this homeostatic balance has been studied extensively but there are a few studies with regards to analysis of the effects of train...
OBJECTIVE The aims of this study were to examine: (i) baseline pressure pain thresholds in patients with chronic fatigue syndrome and those with chronic low back pain compared with healthy subjects; (ii) the change in mean pain threshold in response to exercise; and (iii) associations with exercise-induced increase in nitric oxide. PARTICIPANTS Twenty-six patients with chronic fatigue syndrom...
Exercise is now considered an important component of management in chronic heart failure (CHF), but little is known about central hemodynamic changes that occur during different exercise modalities in these patients. Seventeen patients (ejection fraction 25 +/- 2%) undertook brachial artery and right heart catheterization and oxygen consumption assessment at rest, during submaximal and peak cyc...
PURPOSE Dietary nitrate supplementation has been shown to reduce O2 cost of submaximal exercise, improve exercise tolerance, and enhance performance in moderately trained individuals. In contrast, data have been provided that elite athletes do not benefit from nitrate supplementation. The aim of this study was to evaluate the effects of short-term nitrate supplementation on endurance performanc...
there are confirmed beneficiary effects of exercise on atherosclerotic inflammation of ischemia-associated heart diseases. the purpose of this study was to evaluate the effect of aerobic exercise on t-regulatory cell markers of il-35 as well as foxp3 and t-helper2 marker of il-33 in patients with ischemic heart disease (ihd). this research was performed on 44 asymptomatic male patients with isc...
abstract background and objective: scientific evidence reveals that the density of skeletal muscle microcirculations decreases in the patients with chronic heart failure. therefore, this study aimed to determine the impact of submaximal aerobic exercise training on restoration of fast/slow-twitch muscle fibers microcirculation in rats with myocardial infarction. methods: in thi...
BACKGROUND The best clinical practice to investigate aerobic fitness includes measurements obtained during cardiopulmonary exercise testing (CPET), however it remains an underutilised clinical measure in cystic fibrosis (CF). To investigate this further, different methods of quantifying exercise capacity in CF are required. The possibility that measuring physical activity (PA) by a portable acc...
