Objective: The center of mass is dependent on the distribution of mass and length of the upper parts of the body to the lower parts of the body. This plays a fundamental role in the body's balance, which can be measured in various ways. The purpose of this study was to provide a model for determining the center of mass of girls and boys aged 6 to 12 years.
Methods: Participants in this study were 192 healthy girls and 192 healthy boys who were studying in Isfahan, from which 154850 students were selected through cluster sampling. For this purpose, their mass was measured with a bascule, variables related to stature with meter and center of mass were measured with a weighing machine based on calculating torques. with respect to the multivariate regression assumptions and stepwise method, the variables that had the greatest impact on the center of mass were selected and models were proposed whit them.
Results: The girl’s equation, shows that the stature, body mass index and sitting height per stature ratio, can be used to estimate the center of mass of girl children, and the estimated center of mass for boy children, with stature, sitting height and sitting height per stature ratio, form equation is possible.
Conclusion: It is recommended to use the obtained equations in order to estimate the center of mass of children's bodies, rather than using multiple and sometimes difficult, time-consuming and costly methods and calculations.
Conclusion: It can be said that, in order to calculate the center of mass of child, instead of using multiple and sometimes difficult, time consuming and costly methods and calculations, the equations obtained in this study should be used.
