The aim of this study is to analyze the impact of the HIIT program for 12 weeks on self-control and attention in elementary school girls. In order to accomplish the purpose of this study 34 fifth-grade girls with high self-control scores at S elementary school were selected at random and allocated 17 students each for the exercise group and the control group. The results are as follows. Firstly, the HIIT program for girls with high self-control scores made a contribution to the self-control. The exercise group revealed significant differences statistically, however control group showed no differences for the experiment. Secondly, 12-week HIIT program for girls with high self-control scores made a contribution to the attention persistence. The exercise group revealed significant differences statistically, however control group showed few changes during the experiment. In conclusion, HIIT program for 12 weeks had effect positively with low self-control elementary girls for sub-variables of self-control, impulsivity, adventure seeking, self-centering and sub-variables of attention, attention persistence. It will make a contribution to the exercise program to help improve the self-control and attention.
