中文摘要:

通过对2010年广州亚运会板球测试赛中国女队7名主力投手技术的高速影像解析，从球速、投球臂角速度、投球步落地位置和步长、落地时身体姿态、球出手瞬间关节角等方面分析比较中国女投手的各项投球技术。结果发现：不同类型投手之间技术特征差异性明显，快投手比旋转投手的落地到球出手时间短；好投手比差投手落地位置和空中姿态稳定性好。通过研究还发现部分投手存在球出手时膝关节弯曲、手臂弯曲等技术缺陷，以及前脚越过击球线等技术犯规错误，提醒在比赛中应引起注意。

英文摘要:

With hi-speed video of 7 core bowlers of Chinese Women's Cricket Team in the cricket event before the 2010 Asian Games, the authors tried to analyze the bowling technique of the Chinese women bowlers from the aspects of bowling speed, angle speed of the bowling arm, bowling stride position and length, body gesture at landing, joint angle at the moment of releasing the ball, etc. The result shows that significant difference exists between the technical characteristics of the different-type bowlers. The time from landing to ball releasing of the fast bowlers is shorter than that of the spin bowlers. The landing position and body gesture of the elite bowlers before landing are more stable than those of the lower-level bowlers. Furthermore, some technical deficiencies such as knee collapse at ball releasing, bending elbow and front foot fault are worth notice.
