【摘要】：运用瑞典产QUALISYS-MCU500红外远射测试系统,对王皓、马琳正手弧圈球的动作技术进行了测试。通过对比分析,揭示了王皓和马琳正手弧圈球动作技术的运动学特征与异同,以期为乒乓球动作技术的科学诊断与训练提供依据。得出以下结论:(1)在引拍阶段,与马琳相比,王皓的右上臂离身体较远,右肘伸展的幅度和右髋、膝屈曲程度不如马琳充分;王皓和马琳躯干扭转非常充分。(2)挥拍击球阶段,王皓和马琳膝关节蹬伸动作不明显,伴有明显的旋内动作,蹬伸动作主要是通过展髋来实现,王皓的展髋幅度比马琳小。(3)击球时刻,王皓挥拍的速度低于马琳,一定程度上表明王皓正手直板弧圈球技术的击球效果不及马琳。
[Abstract]:Using Swedish QUALISYS-MCU500 infrared long shot test system, the paper tests the action technology of Wang Hao and Ma Lin forehand arc ball. Through comparative analysis, this paper reveals the kinematics characteristics and similarities and differences of forehand arc ball technique between Wang Hao and Ma Lin, in order to provide the basis for scientific diagnosis and training of table tennis action technique. The following conclusions are drawn: during the initiation stage, Wang Hao's right upper arm is farther away from the body than Ma Lin, and the right elbow extension and right hip flexion degree are not as good as Ma Lin's; Wang Hao and Ma Lin torso torsion is very adequate. The Wang Hao and Ma Lin knee joint pedal and extension movements were not obvious, accompanied by obvious pronation movements, the pedal and extension movements were mainly realized through the extension of the hip, the Wang Hao's hip extension amplitude was smaller than Ma Lin (3) hit time, the Wang Hao swing speed was lower than Ma Lin. To a certain extent, Wang Hao's forehand straight-board loop technique is not as effective as Ma Lin.
