滑冰与羽毛球运动对7～8岁健康男性青少年 静态平衡能力的影响

目的]探讨滑冰与羽毛球运动对青少年静态平衡能力的影响。方法]采取试验法、文献资料法及数理统计法,通过招募90名7～8岁健康男性青少年作为研究对象,随机分成滑冰组、羽毛球组和对照组,每组均30人,3组受试者在身高、体重、年龄3项指标上均无统计学意义(P0.05)。对滑冰组和羽毛球组进行12周的运动干预,试验前后采用IIM-BAL-100平衡机能测试仪进行静态平衡测试,实验所得数据应用单因素方差进行分析。结果]滑冰组与对照组在睁眼双足站立和睁眼线型步2种站姿的4项测试指标,即重心动摇速度、重心动摇角度、外周面积和动摇总轨迹长方面均具有非常显著性差异(P0.01);羽毛球组与对照组在5种站姿指标对比中具有显著性差异(P0.05);滑冰组与羽毛球组对比,在双足睁眼与右足睁眼站立测试中,外周面积和动摇总轨迹长2项指标存在非常显著性差异(P0.01)。结论]滑冰与羽毛球运动都能改善青少年的静态平衡能力,且滑冰运动的效果优于羽毛球运动。

Effects of Skating and Badminton on the Static Balance Ability of 7-8 Year-old Healthy Male Adolescents

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.
