Background and Aim: Heart rate variability used as a non-invasive method to investigate the effect of aerobics exercise on the cardiac autonomic system. The aim of this study was the nonlinear analysis of the effect of aerobic exercise in the water on the cardiac autonomic system in academic young's males.
Materials and Methods: A total of 28 young men were purposefully selected and randomly assigned to two groups of control and aerobic exercise in water. In the pre-test period and after the training intervention, all parameters of heart rate variability were measured by examining heart rate sequences, In the pre-test period and after the training intervention, all parameters of heart rate variability were measured by examining heart rate sequences, and then the standard deviation of the recorded sequences was interpreted by using the Poincare plot method. Independent t-test and paired t-test were used to compare the differences in the research stages.
Results: Regular participation in aerobic exercise in water caused a significant (45.1±9.2 vs. 34.1±12.3)  and standard deviation of time intervals of heart rate sequences compared to their adjacent sequence compared to the control group (P=0.03). The longitudinal standard deviation of time intervals of heart rate sequences compared to the pre-test (P = 0.04) had a significant increase (79.5±12.5 vs. 56.9±15.8 After transferring the absolute results to normal, the normal state of the standard deviation of time intervals of heart rate sequences compared to its adjacent sequence compared to the control group (P=0.03) had a significant increase (44.7±12.05 vs. 36.5±13.52). Also, the normal state of the longitudinal standard deviation of time intervals of heart rate sequences compared to the pre-test (P=0.02) increased significantly (76.4±15.29 vs. 61.3±9.32).
Conclusion: Performing aerobic exercise in an aqueous environment can be used as a useful training method to improve the responsiveness of the cardiac autonomic system.
