直拍正手下旋弧圈球与长胶下旋提拉技术对比

Spiral loop and the forehand backspin long rubber from under techniques

阐述了反胶和长胶的不同性能和特点.采用三台摄像机和乒乓球发球机,分别用反胶和长胶在相同用力下,对直拍正手下旋弧圈球和直拍长胶下旋提拉技术进行了对比分析.发现二者身体形态基本一致,击球点位略有不同;击球前引拍方向略有不同,但都向前上方用力;击球时,反胶摩擦较大,长胶几乎没有摩擦;球拍和球接触瞬间的位置略显不同;长胶要注意翻腕和击球力量的控制.

The writer of this paper demonstrates different performances by spiral loop and the forehand backspin long rubber from under techniques in playing table tennis on machines. Three cameras are provid- ed via different angles. The poises and differed strokes are discussed for modified restrictions and controls.
