the purpose of this study was to compare the effect of a walking (8wk) training program on quality, quantity and some physiological parameters related to sleep in old men. twenty elderly healthy men (age 72.4?7.24 years, height: 163.59?6.11 cm, weight 68.31?9.19kg) were selected randomly and were divided into two groups [walking (n=10) and control (n=10)]. the walking group exercised for eight ...

Background Exposure to environmental tobacco smoke (ETS) has been epidemiologically linked to death from ischemic heart disease in nonsmokers. In this study, we evaluated the influence of 3 days, 3 weeks, and 6 weeks of ETS exposure on myocardial infarct size in a rat ischemia/reperfusion model. Methods and Results Sprague-Dawley rats exposed to ETS (four Marlboro cigarettes per 15 minutes, 6 h...

The effectiveness of water-training in maintaining cardiorespiratory endurance was investigated in 16 cross country athletes, 18--24 years. Following a competitive season, subjects were stress-tested (T1) and divided into three equated groups based on VO2 max. Group I (n=5) continued training as it had during the competition season. Group II (n=5) underwent an experimental period of water-train...

Twenty five subjects were randomized to untrained (UN) and resistive-trained (RT) groups. The RT group exercised three sessions per week at 60%-70% of the load according to individual 1RM test during 24 weeks. Both groups were evaluated before and after protocol period assessing lumbar spine (LS) and femoral neck (FN) BMD by dual-energy X-ray absorptiometry, VO(2) max, and neuromuscular fitness...

introduction: the aim of this study was to evaluate the effects of aerobic exercise on brain natriuretic peptide (bnp) and c-reactive protein (crp) levels in women with cardiovascular diseases. materials and methods: in this semi experimental study, thirty female patients with at least one coronary artery stenosis (more than70%) were chosen and divided into two groups of aerobic training (n=15)...

This study had the following objectives: 1) to determine whether diabetic rats could increase muscle mass due to a physiological manipulation (chronic resistance exercise), 2) to determine whether exercise training status modifies the effect of the last bout of exercise on elevations in rates of protein synthesis, and 3) to determine whether chronic resistance exercise alters basal glycemia.
