Morphofunctional evaluation of the heart of rats subjected to aquatic exercises

Exercise programs in rats, such as aerobic exercise and swimming are widely used to identify the benefits of this therapy for the cardiovascular system, this condition implies the need for records that seek evidence of cardiovascular adaptations in animals submitted to physical training. The influence of aquatic therapy on morphological and structural alterations in cardiac my ocytes and electrophysiological and hemodynamic characteristics are not yet clarified in the literature. Having this as a starting point, this work aims to study the implications of aquatic activities on the morpho-functional activity of the heart of rats. This is an experimental study, in which 10 Wistar rats supplied by the central bioterium of the UnirG University Center subdivided into a control group (CG, n=5) and in the experimental group (EG, n=5) were used, will be submitted to aquatic therapy at a temperature, 33ºC for 6 weeks with a load increment of 8% of body weight. Heart rate parameters, QRS amplitudes, and QT intervals will be evaluated in vivo by means of an electrocardiogram, and the data analyzed using the Student T-test at a significance level of 5% will be evaluated.
