SRM训练系统在场地短距离自行车运动员专项力量训练中的应用

通过对上海市男子短距离自行车运动员在10运会前一年的比赛、训练情况进行连续追踪,应用SRM训练系统对运动员在训练和比赛情况进行分析,对SRM训练系统在自行车运动员专项力量训练中的应用进行了探讨,结果发现：（1）使用SRM训练系统可以监测自行车运动员比赛或训练中的实时情况,通过功率、速度以及频率等指标,可以反映自行车运动员专项能力的变化情况。（2）自行车运动员的运动成绩取决于专项力量的大小,而不是绝对力量的高低。（3）自行车运动员的专项力量是在自行车运动中表现出来的一种高频率的踏蹬力量。

Kinematic and kinetic variability associated with the cable put and seated rotation assessments

ABSTRACT

When new protocols are developed, there is a requirement to investigate test–retest reliability of measures for valid use and interpretation of data in research and practice. Therefore, the aim of this investigation was to determine the inter-day reliability of the cable put and seated rotation assessment protocols. On three occasions, nine resistance-trained men performed cable puts and cable rotations at different loads between 6 and 42 kg on a commercially available cable cross over machine. Load stack movement was recorded using a PT5A linear position transducer from which all kinematic and kinetic variables were calculated. Reliability was excellent for peak velocity and displacement based on intraclass correlation coefficient (ICC) and coefficient of variation (CV) across the majority of loads and movements (cable put: ICC = 0.92 to 0.99, CV = 3.1% to 8.6%; cable seated rotation: ICC = 0.76 to 0.99, CV = ?1.7% to 16.1%). However, kinetic variables demonstrated inadequate reliability across the majority of days, loads and movements (ICC = 0.70, CV >10%). It was concluded that peak velocity is a reliable kinematic measure to assess muscular capability from cable put and seated rotation protocols; however, kinetic measures are too variable to provide reliable outputs across testing occasions.     

Modeling pollutant transport in overland flow over non-planar and non-homogenous infiltrating surfaces

Pollutant transport in overland flow over surfaces with spatially varying microtopography,roughness,and infiltration was investigated using the diffusion wave equation and transport rate-based equation.The finite volume method in space and an implicit backward difference scheme in time were employed in the numerical solution of the 2D governing equations.The developed model was first tested against an analytical solution and an experimental study involving overland flow and the associated pollutant transport,subsequently a series of numerical tests were carried out.Non-point source pollution was investigated under spatially varying microtopography,roughness,and infiltration.The simulation results showed that microtopography and roughness were the dominant factors causing significant spatial variations in solute concentration.When the spatially varying microtopography was replaced by a smooth surface,the result was an overestimation of the solute rate at the outlet of the upland.On the other hand,when the spatially varying roughness was replaced by the average roughness and spatially varying infiltration rate by the average infiltration rate,the pollutant discharge at the outlet of the upland was not significantly affected.The numerical results further showed that one cannot ignore the spatial variations of slope and roughness when investigating the local pollutant concentration distribution.     

对高校田径运动会的思考——以黄山学院为例

通过运用文献资料法、问卷调查法、数理统计法及观察比赛过程中出现的一些现象和问题,对赛场上出现的一些问题进行分析研究,提出相应的对策,并对今后田径运动会的开展方向给出相应的建议。具体建议:高校田径运动会应以“健康第一”为主线,突出体验性、团体性和地域性,重参与的体育精神应该贯穿运动会的始终;鼓励运动会由各个学院联合承办;多增设一些小、中、大型的团体性趣味项目和当地民俗体育项目;应将团体名次纳入年终考评。
