the effect of national jump roping plan on static and dynamic balance of male students of elementary school fourth grade

the aim of this study was to investigate national jump roping plan on static and dynamic balance of students. in this study, pretest and posttest were used with two experimental and control groups for male students of fourth grade of elementary school in 2011-2012 in baharestan city (a region in robat karim, tehran). for this purpose, 60 students were selected from students of fourth grade of elementary schools in baharestan city using multistage sampling method and were equally divided into two groups. experimental group implemented the selected jump roping program 3 sessions a week (each session 50 min.) for 10 weeks. k–s test was used to check data normality. independent and dependent t tests were used to analyze the data (p˂0.05). the results indicated a significant improvement in the experimental group for both static (p=0.019) and dynamic (p=0.005) balance tests. also, the mean score of dynamic balance posttest was significantly more in the experimental group than control group (p=0.041) but such difference was not observed in the result of static balance test between the two groups (p=0.225). based on these results, jump roping plan improved the balance of students. so this study considered the jump roping plan to be useful at schools.
