background & objectives: several epidemiological studies have indicated factors such as leptin level, adiponectin and plasma adiponectin-to-leptin index to be the predicting biomarkers for cardiovascular diseases. given the importance of healthy nutrition and adequate exercise in reducing the risk of atherosclerosis, this study aimed to investigate the effects of fasting and aerobic exercise on...

The aim of this study was to evaluate and compare the plasma concentration of atrial natriuretic factor (ANF), K+, Na+, blood lactate, heart rate, and blood pressure in moderately trained women. Ten healthy women were studied on a cycle ergometer during 20 min of constant submaximal and maximal exercise, as well as during recovery. The ANF concentration was determined by radioimmunoassay. The r...

The article examines the effect on heart rate variability (HRV) indices in athletes depending training status, different types of physical exertion, gender and age, presented both cross-sectional longitudinal studies. Also included is predictability HRV during overtraining, athletic condition, performance. Heart has long been used as a diagnostic marker overexertion overtraining. A large body e...

introduction: stumbling or falling is a major health problem among the elderly which accounts for their majority of physical injuries such as pelvic fractures, disability, loss of independency and even death. the goal of the study was comparison of the effect of aerobic and resistance exercise on static and dynamic balance in old men. methods: a quasi-experimental study was conducted and thirty...

The regular practice of physical exercises is an important factor to reduce morbidity and mortality rates of cardiovascular and all other conditions1,2; there also seems to have further and independent benefits from the practice of physical exercises and improvement of the aerobic condition3-6, which speaks for their being practiced more and more frequently. The American Heart Association recom...

To examine the electrocardiographic response to exercise in an older population, 280 participants in a longitudinal study of cerebrovascular disease were tested. Subjects were randomly selected from the total 50 to 69-year-old population of Birmingham, Alabama. Approximately 60% of the participants reached a heart rate more than 80% of their predicted maximal heart rate. Subjects were divided i...

purpose aerobic exercise has been identified as the main treatment for type 2 diabetic patients. such an exercise, however, is usually repined by some of patients who suffer from lack of stamina. therefore, whole body vibration has recently been introduced as a passive intervention. the present study aimed at comparing how aerobic exercise and whole body vibration affect glycaemia control in ty...

The maximal accumulated oxygen deficit (MAOD) method has been extensively, but unfortunately not very methodically, used; the procedure used to determine the MAOD varies considerably. Therefore, this review evaluates the effect of different numbers and durations of submaximal exercise bouts on the linear power output (PO)-oxygen uptake ((.)VO2) relationship and thus the MAOD. Changing the numbe...

Exercise conditioning involves adaptations in the heart, peripheral circulation, and trained skeletal muscle that result in improved exercise capacity. Since the specific influence of /3adrenergic stimulation on these various adaptations has not been clear, we studied the effect of 3,1selective and nonselective ,B-adrenergic blockade on the exercise conditioning response of 24 healthy, sedentar...

The hypoxic exercise test combining a 4,800-m simulated altitude and a cycloergometer exercise at 30% of normoxic maximal aerobic power (MAP) is used to evaluate the individual chemosensitivity to hypoxia in submaximal exercise conditions. This test allows the calculation of three main parameters: the decrease in arterial oxygen saturation induced by hypoxia at exercise (ΔSa(e)) and the ventila...
