Background & Aims: The heart rhythm is controlled by the autonomic nervous system from the pathway of the heart's sinoatrial node. This study aimed to evaluate the heart rate fluctuations in academic active men after performing a short period of continuous aerobic exercise using two frequency and time domain techniques.
Materials & Methods: In total, 30 healthy young men were selected and randomly allocated to groups of control, aerobic training, and water aerobic training. All heart rate variability parameters were measured before pretest and after the intervention. In addition, repeated measures ANOVA was exploited to compare the differences in research stages.
Results: In this study, aerobic training significantly increased the high frequency waves (HF), low frequency waves (LF) and ratio of low-frequency to high-frequency waves (LF/HF) while reducing total power (TP) and time-domain parameters of heart rate variability, including SDNN, SDANN, pNN50, and rMSSD, compared to the control and water aerobic training groups (P=0.001). Furthermore, water aerobic training reduced the ratio of LF to HF waves, compared to other studies, which was not significant (P=0.07).
Conclusion: It is recommended that aerobic exercises (out of water) be performed in comparison to water aerobic exercises in order to have a better heart rate variability.
