体育舞蹈专业学生足底生物力学性别特征以及差异性研究

Research on the Gender Characteristics and Differences of Planter Biomechanics of Sports Dance Majors Students

为了探究体育舞蹈专业大学生男女性别的足底生物压力特征,分析长期训练后不同性别足底压力的差异性,为长期参加体育舞蹈训练的大学生提供预防足底损伤的理论参考,通过使用Free Step V3 Manual足底压力测试系统对体育舞蹈专项学生男女共34名进行裸足静态站姿、裸足步态测试.结果如下:(1)裸足静态测试中,男性前足面积占比显著大于女性前足面积占比;女性后足负荷比大于男性后足负荷比.(2)AI指数女性显著小于男性.(3)女性的MFM值、左足T2345以及HL的负荷比显著大于男性;而男性的M1和M5的负荷比大于女性.(4)MFM、左足T2345和右足HM压强峰值女性显著大于男性.(5)M12345、右足T1和左足MFL压力-时间积分男性显著大于女性;右足MFM的压力-时间积分女性显著大于男性.(6)压力中心纵轴的水平偏移量男性显著大于女性.

In order to explore the characteristics of plantar pressure of male and female college students,this paper analyzes the difference of plantar pressure after long-term training,and provides the theoretical reference for college students who participate in sports dance training for a long time.By using the Free Step V3 Manual plantar stress testing system,34 male and female students were tested for naked foot static standing posture and naked foot gait.The results shows:(1)In the static test of bare foot,the proportion of male forefoot area is significantly greater than that of female's;the proportion of female hind foot load ratio is greater than that of male's.(2)The AI index of women is significantly lower than that of men.(3)The MFM value,left foot T2345 and HL load ratio of women are significantly higher than those of men.The load ratio of M1 and M5 in men is greater than that in women.(4)The peak pressure of MFM,left foot T2345 and right foot HM are significantly greater in females than in males.(5)M12345,right foot T1 and left foot MFL pressure-time scores are significantly greater in males than in females;the pressure-time integral of right foot MFM is significantly greater in females than in males.(6)The horizontal offset of the longitudinal axis of the pressure center is significantly greater in males than in females.
