Postmenopause is associated with the development of cardiovascular disease, such as hypertension. However, limited information is available regarding effects of exercise on cardiovascular responses and its underlying mechanisms in the simultaneous postmenopausal and hypertensive status. We aimed to investigate whether acute exercise could enhance vasodilation mediated by acetylcholine (ACh) and...

Stem cell therapy for myocardial infarction (MI) has been shown to improve cardiac function and reduce infarct size. Exercise training, in the form of cardiac rehabilitation, is an essential part of patient care post-MI. Hence, we tested the effects of acute and chronic aerobic exercise on stem cell retention and cardiac remodeling post-MI. Small epicardial MI's were induced in 12-month-old C57...

OBJECTIVE: Recent studies have concluded that an energy expenditure by an acute exercise session has no immediate effect on leptin levels while some showed a decline in leptin levels. The purpose of this study was to investigate any possible effects of training status of the subjects on acute exercise-leptin relationship in obese patients. MATERIALS AND METHODS: Fourteen obese sedentary females...

We investigated the effects of acute endurance exercise and habitual physical activity for health maintenance on human neutrophil function in 12 untrained men. The acute exercise condition was a continuous exercise for 90 minutes at the intensity of 50% and 55% of maximal oxygen uptake (VO2max) on an ergometer. The training program was 3 km jogging three times per week for 8 weeks. The capacity...

There is increasing evidence that acute aerobic exercise is associated with improved cognitive function. However, neural correlates of its cognitive plasticity remain largely unknown. The present study examined the effect of a session of acute aerobic exercise on working memory task-evoked brain activity as well as task performance. A within-subjects design with a counterbalanced order was empl...

The duration of action of single oral doses of 80 and 160 mg of propranolol during acute and sustained therapy was studied in nine patients with stable, exercise-induced angina pectoris. Plasma propranolol levels peaked 2 hours after both doses during acute and sustained therapy, but there were wide variations between individuals in plasma concentration with both dosage schedules. Plasma half-l...

BACKGROUND/AIM Many studies support the hypothesis that oxidative stress is involved in the pathogenic process of a variety of diseases including hypertension. In humans, hypertension is also considered a state of oxidative stress that can contribute to the development of arteriosclerosis and other hypertension-induced organ damage. The aim of this study was to evaluate an influence of acute ph...

OBJECTIVE The goal of this study was to assess the acute effect of physical exercise on the cognitive function of depressed elderly patients in a dual-task experiment. INTRODUCTION Physical exercise has a positive effect on the brain and may even act as a treatment for major depressive disorder. However, the effects of acute cardiovascular exercise on cognitive function during and after one s...

Physical activity and aerobic exercise in particular, promotes health and effective cognitive functioning. To elucidate mechanisms underlying the beneficial effects of physical fitness and acute exercise, behavioral and electrophysiological indices of task preparation and response inhibition as a part of executive functions were assessed in a modified version of an Eriksen flanker task subseque...
