Effects of soda consumption on cardiac tissue in rats submitted to concurrent training.

Abstract The association of aerobic resistance training (ART) and strength training (ST) is called "concurrent training" (CT), and this type of training can help combat the emergence of cardiovascular diseases. Despite the benefits of ST[U1] , it is known that a good portion of the population consumes soft drinks, which can bring negative consequences for health, especially the heart. The aim of this study was to compare the effects caused in cardiac tissue of animals that consumed soda and performed a CT protocol. Thirty-two male Wistar rats were used, subdivided into four groups: Control (C [n=8]); Soda Consumption (SC [n=8]); Concurrent Training (CT [n=8]); and CT with Soda Consumption (CTSC) [n=8]). The CT was composed of aerobic swimming exercises and resistance exercises through jumps in the aquatic environment. The animals performed 3 training sessions per week for 4 weeks. CT promoted an increase in the area, perimeter, and diameter of cardiomyocytes, while the consumption of soda, both isolated and added to the CT, did not generate alterations in the variables analyzed. CT generated an increase in cardiomyocytes and the consumption of soda caused a decrease in these cells. However, this decrease showed no statistically significant difference. [U1]Deveria ser ‘CT’?
