abstract        background and objective: doxorubicin (dox) is an effective anticancer drug. it has been shown that  a short-term exercise performed prior to dox-treatment has no effect on cardiotoxicity in young rats. in the present study, old and young rats were evaluated to determine the protective effects of pre-treatment with short-term exercise on dox-induced oxidative damage in cardiac t...

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...

conclusions overall, the results of this study indicate that intermittent exercise reduces the plasma leptin level. in addition, this reduction is significantly correlated to the glucose level in the blood. the continuous exercise was shown to have no effects on the plasma leptin level, and there was no relationship between the glucose and leptin levels. results the results demonstrated that se...

BACKGROUND Many secondary abnormalities in chronic heart failure (CHF) may reflect physical deconditioning. There has been no prospective, controlled study of the effects of physical training on hemodynamics and autonomic function in CHF. METHODS AND RESULTS In a controlled crossover trial of 8 weeks of exercise training, 17 men with stable moderate to severe CHF (age, 61.8 +/- 1.5 years; lef...

PURPOSE To investigate the blood pressure responses during recovery after two protocols of circuit resistance exercises (CRE) with different rest intervals (RI). METHODS Eleven normotensive males (aged 19.5 ± 1.0 yrs, height 172.8 ± 5.7 cm and weight 65.1 ± 8.1 kg) performed two CRE with RI of 30 (RI30s) and 40 (RI40s) seconds between the exercises randomly, as well as a control session witho...

The purpose of the study was to determine whether eight weeks of plyometric training can improve male handball players agility. To achieve the purpose thirty (30) male handball players were selected randomly from Department of Physical Education and Sports Sciences, Annamalai University, Chidambaram, Tamilnadu. These players were divided into two groups namely, plyometric training group (15) an...

One important factor in cardiac rehabilitation and training is the correct analysis of aerobic and anaerobic thresholds for individual training plans. Several published algorithms produce exact results within a very homogeneous group of subjects (similar age, weight and level of fitness). We implemented these algorithms and evaluated their accuracy against data of a heterogeneous group of subje...
