The Effect of One Period of Rhythmic Exercises and یدبستا پیص Simultaneous Consumption of Iron and Zinc Supplementation on Gross Motor Skills Development of Preschool Children

The aim of this study was to compare the effect of 12 weeks of rhythmic exercises and simultaneous consumption of iron and zinc supplementation on gross motor skills development of preschool children. Research design was quasi-experimental with pretest-posttest with a control group. The statistical population consisted of preschool children aged between 4 and 6 of district 2 in Tehran. 48 subjects who were eligible to take part in the study were selected as the sample and were randomly assigned to 4 groups: control, supplement, exercise, exercise + supplement. The Test of Gross Motor Development Second Edition (TGMD-2) was used to measure motor development. After the pretest, the exercise group performed rhythmic exercises for 12 weeks, 2 sessions per week and he supplement groups consumed 5 cc of ferrous sulfate and zinc sulfate syrups daily. The data were analyzed using univariate and multivariate covariance analyses (ANCOVA and MANCOVA). The results showed that gross motor skills development of children in supplement, exercise and exercise + supplement groups was significantly higher than the control group, and gross motor skills development of children in exercise + supplement group was more than the exercise group and supplement group. It seems that in order to develop gross motor skills, it is better for children to take iron and zinc supplements along with rhythmic exercises simultaneously.
