| 摘要: |
| 运用Qualisys三维运动采集与分析系统、表面肌电测试系统分别对20名成人与少儿男子乒乓球参训者的正、反手近台攻球技术动作进行测试，比较分析相关数据发现：少儿在标准高度球台上的正、反手攻球技术动作模式与成人有着明显的差异；少儿在身高较低的年龄阶段难以做到与成年人相同的技术动作模式；少儿在适当降低高度的球台上练习后，击球动作结构明显有着更为接近成人的变化趋势。因此，合理降低少儿乒乓球运动用台的高度是最直接有效的方法，其不仅有助于少儿在训练初期更好地形成合理的技术动作动力定型，减少肩部运动损伤发生，保障技战术训练进程有序推进，亦不会影响少儿后续参加更高级的比赛。最后，提供了适合不同身高的少儿乒乓球运动用台高度计算公式。此外，为解决成人陪练和不同身高段少儿之间对练等问题，提出了铺设相应高度的垫板，应用可调节高度的球台支架，及两者组合使用的可行性方案。 |

| Abstract: |
| This paper tests the forehand attack and backhand attack of 20 adult and 20 children table tennis players using threedimensional motion acquisition and analysis system and surface electromyography test system by Qualisys. Through comparative analysis of the relevant data, we can find out that there are obvious differences between children and adults in forehand and backhand attack on the standard height table. It is difficult for children to achieve the same technical action mode as adults in the lower age, but after children practice on the table with proper height reduction, the structure of hitting action is obviously closer to adults. Therefore, it is a direct and effective way to reduce the height of table tennis table for children. It not only helps children to form a reasonable dynamic pattern of technical movements in the early stage of training, reduces the occurrence of shoulder injuries, ensures the orderly progress of technical and tactical training, but also does not affect children’s subsequent participation in higherlevel competitions. Finally, the formula of table height suitable for children with different heights is provided. In addition, in order to solve the problems of adult accompany practice and children of different height, this paper puts forward the feasible scheme of laying the corresponding height of the base plate, using the adjustable height of the ball stand, and the combination of the two. |
