Aim: The aim of this research was the effect of Escalating Density Training along with whey protein supplement on the morphological parameters of the heart of bodybuilding athletes.
Methods: 40 elite bodybuilders from Shiraz city were randomly selected and divided into four groups: EDT training, EDT training + whey protein supplement, traditional training and traditional training + whey protein supplement. Then, before starting the research project and at the end of the 8th week, heart echocardiography was performed on the subjects. The morphological indicators of the heart including IVST, PWT, AR, LVEDD, LVESD, LAdim and functional indicators including EF were investigated in these people before and after the exercise training period.
Results: The results showed that in IVST and PWT variables, EDT+supplement group experienced a significant increase compared to other research groups (P=0.001). Also, the EDT group experienced a significant decrease in the post-test compared to the pre-test (P=0.039). A significant difference was observed in the LVEDD and LVESD variables between the EDT alone and EDT + supplement groups, so that in the post-test, the EDT + supplement group had a significant decrease (P=0.001) and the EDT group had a significant increase (P = 0.001). On the other hand, there was a significant difference in injection fraction between the EDT+supplement and EDT with traditional exercises and traditional+supplement exercises groups (P=0.001).
Conclusion: EDT training can improve the morphological factors of the heart, which increases these positive effects on the heart with the help of whey protein.
