Changes in cardiac function parameters in 12-13-week-old, high-intensity exercised, healthy white experimental rats

The aim of the study was to evaluate cardiac functional parameters after 11 weeks dosed, high-intensity exercises on a treadmill in 12-13-week-old healthy rats. In general, physical activity is cheapest and safest method reduce cardiovascular disease risk factors (1,2,3). Within scope our study, we subjected male rats exercise for then studied function by echocardiography assess effects heart. were divided into 2 groups: 1) control group, which did not receive any execrise (n=8); 2) group performed 10 full rotations per day, with 1-minute active breaks between, 5 days week (treadmill speed 19m/min, incline 300) – n=8.Cardiac assessed through transthoracic twice (at start weeks). Compared there changes terms improvement particular, ejection fraction, stroke volume, left ventricular wall thickness, end-diastolic volume increased, contrary, end-systolic decreased, compared data non-trained same sex age.The present can be considered as another step forward heart developed background activity.
