Purpose: Desirable effects of exercise on cardiovascular health in pediatrics due to different physiology than other ages, has not been well elucidated. The aim of this study was to effect of 12 weeks of moderate-intensity aerobic exercise on cardiac structural and functional parameters in pediatrics.
Methods: Twenty healthy pediatrics (without regular training background) with average age of 10-12 years participated in this study. Subjects were randomized to one of two groups: control (n=10) and exercise (n=10). The subjects in the exercise group performed aerobic exercise training up to 55 -70% of heart rate reserve, three sessions per week, 25 to min per session for 12 weeks. The cardiac structural and functional parameters were measured with Echocardiography system at baseline and end of 12 week exercise training. The research data were analyzed using independent t- test and Paired t- test (p < 0.05).
Results: In the exercise group in comparison to the control group and baseline conditions LVEDd, LVmass, LVEDV and VO2peak significantly increased (p < 0.05) and resting heart rate decreased (p < 0.05) after 12 weeks moderate intensity aerobic exercise.
Conclusion: The results of present study demonstrates that after 12 weeks moderate intensity aerobic exercise some of cardiac structural and functional parameters in pediatrics will improve, As these changes can have an effective role in improvement of Pediatrics cardiovascular system.
