The effects of ACL injury on quadriceps and hamstring torque,work and power

The aim of this study was to assess isokinetic torque, work and power between non-injured, ACL (anterior cruciate ligament)-deficient and ACL-reconstructed individuals. Ten healthy, non-injured individuals, seven unilateral ACL-deficient individuals and six unilateral ACL-reconstructed individuals were assessed for isokinetic quadriceps and hamstring strength at 1.05 and 3.14 rad.s-1. Peak torque, total work, average power and the ratio of peak torque to body mass were computed for both velocities. Peak torque was also corrected for body mass, using allometric modelling. The non-injured individuals showed significantly greater quadriceps peak torque to body mass ratios than the ACL-deficient and ACL-reconstructed individuals at both velocities, and greater hamstring peak torque to body mass ratios than the ACL-deficient group at 3.14 rad.s-1 (P < 0.05). The ACL-deficient individuals displayed greater quadriceps and hamstring peak torque, total work and average power than the non-injured individuals at 1.05 rad.s-1 (P < 0.05). The ACL-deficient individuals also displayed significantly greater peak torque, total work and average power than the ACL-reconstructed individuals for the quadriceps at both velocities (P < 0.05). The ACL-deficient individuals demonstrated greater hamstring peak torque and total work than the non-injured individuals at both velocities (P < 0.05). The allometrically modelled peak torques at both isokinetic velocities demonstrated that the quadriceps muscle values were significantly higher in the non-involved than the involved limb. The hamstring peak torques corrected for body mass were significantly higher in the non-involved than the involved limb only at 1.05 rad.s-1. The main finding from the present study is that isokinetic measures in ratio-scaled or absolute units yield a different outcome and, hence, interpretation compared with the allometric approach.

我国传统养生理论中的经络学说

根据我国传统养生理论的观点,结合人体运动及针灸、气功修炼实践,对经络学说作了全面的剖析,提出:人体运动,经络通畅;经络既通,其形乃彰;经络失常,人体衰老;疏通经络,延年益寿等观点,为人们的运动健身和养生保健提供有益的借鉴。     

第12届欧洲杯足球赛参赛各队技战术运用能力的综合评价

对第12届世界杯足球赛16支球队31场比赛的9项攻防指标进行Q聚类统计,并对各聚类指标的差异性进行方差分析和多重比较,运用等级相关法对聚类结果进行检验,表明应用Q型聚类对球队的各项指标进行量化评价具有较高的可靠性,结果客观反映了各队技战术综合实力.揭示了欧洲足球运动的发展趋势,并探索一种较合理有效的量化评价球队技战术能力的方法.
