Due to the increasing tendency of children to the soccer the purpose of this investigation was to examine the effects of a 12 week plyometric and soccer training on the cardiac structure and function of healthy 13-15 years old boys. Materials and Methods: This quasi- experimental study was conducted with a pre-test and post-test design. The participants (n=20) were selected among the non-athletic healthy boys (13-15 years) from Miyaneh (East Azerbaijan, Iran). After taking informed consent the participants were voluntarily participated in two equal Training and Control groups. The participants in the Exercise group performed a 12 week plyometric and soccer training. Under basic conditions and after a 12 week follow-up using the echocardiography both groups were examined for left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic dimension (LVESD), left ventricular end diastolic posterior wall dimension­ (LVPWd), inter-ventricular septal end diastolic dimension (IVSd), stroke volume (SV), ejection fraction (EF) and cardiac output (CO). Results: After a 12 week training program the LVEDD, LVPWd and SV were significantly increased (P<0.05). The EF in the Exercise group had no increase. Moreover, LVESD and IVSd were similar in both groups. Conclusion: A twelve week plyometric and soccer training in 13-15 years old boys result in significant changes in some cardiac structural and functional indexes. %> http://feyz.kaums.ac.ir/article-1-3287-en.pdf %P 94-101 %& 94 %! %9 Research %L A-10-176-1331 %+ Department of Physical Education , Faculty of Physical Education and Sport Sciences, University of Mohaghegh Ardabili, Ardabil, I.
