[Objective] To explore the effects of skating and badminton on the static balance ability of 7-8 year old children. [Methods] Experiments, literature and mathematical statistics were used, and 90 healthy male adolescents aged 7-8 were recruited as the research objects. They were randomly divided into skating group, badminton group and control group with 30 participants in each group. The height, weight and age of the subjects in the three groups showed no statistical significance (P>0.05). The skating group and the badminton group were given sports intervention for 12 weeks. Iim-bal-100 balance function tester was used for static balance test before and after the experiment. The data obtained from the experiment was analyzed by one-way variance. [Results] There were significant differences between the skating group and the control group in the four test indexes of bipedal standing with open eyes and linear walking with open eyes: velocity of center of gravity, angle of center of gravity, peripheral area and total track length of center of gravity (P<0.01).There was a significant difference between the badminton group and the control group in the five standing posture indexes (P<0.05). Compared with the badminton group, there were significant differences in peripheral area and total trajectory length (P<0.01) for the skating group. [Conclusion] Both skating and badminton can improve the static balance ability of 7-8 year-old children, and the effect of skating is better than that of badminton.
