摘要
运用三维测力台(Kistler)和红外光点自动捕捉测试系统(Qualisys-MCU500)对北京体育大学男子排球队9名运动员分别进行了摆臂纵跳和抱头纵跳的测试,结果表明:摆臂纵跳蹬伸过程中最大力值大于抱头纵跳,但是由于蹬伸后半段时间的延长使后半段蹬伸力的梯度值没有明显增加;落地时地面最大冲击力与纵跳高度无关;摆臂纵跳的冲量值大于抱头纵跳,但研究结果发现纵跳高度与冲量并没有显著性相关关系。
By using a 3D force measurement platform（Kistler） and an infrared light sport automatic capture system（Qualisys-MCU500）,the authors run arms-swinging vertical jumping and head-held vertical jumping tests respectively on 9 layers in the men’s volleyball team of Beijing Sport University,and revealed the following findings： the maximum force measured in the process of arms-swinging vertical jumping and stretching was greater than the maximum force measured in the process of head-held vertical jumping,but the gradient of stretching force in the second half period did not increase significantly as a result of the extension of the second half period of stretching;the maximum ground impact force at landing was irrelevant to vertical jumping height;the impulse of arms-swinging vertical jumping was greater than the impulse of head-held vertical jumping,but from the research results it was found that there was no significant correlation between vertical jumping height and impulse.
