通过文献资料法、访谈法、问卷调查和数理统计等研究方法,对我国赛艇运动员退役后就业问题进行了调查研究,分析了我国的专业赛艇运动员再就业问题的重要性和必要性,并且对于构建和谐社会以及退役运动员再就业的因素进行深刻的研究,结果表明：我国赛艇退役运动员就业难的原因主要有运动员退役保障、安置体制不健全、运动员综合素质低下、退役运动员就业渠道窄、运动员训练体制不合理、法规体制的矛盾冲突等。从赛艇运动员相对其它体育项目的运动员再就业更困难的原因出发,提出构建和谐社会进程中解决赛艇运动员退役再就业难的若干对策。 相似文献

论《诗经》中的舟船意象 总被引：1，自引：0，他引：1
《诗经》里有大量篇章描写到舟船这一意象，诗人或凭舟船渲染男女情思，或以舟船直抒羁旅乡愁，或借舟船象征君臣遇合。《诗经》中的舟船作为一种独特的审美意象，凝聚着人们驾舟行船的切身体验和日常的生活感受，反映着人类的志趣情感和文化精神，乃是诗人的心境、情绪的寄寓和外化形式。 相似文献

ABSTRACTThe choice of marathon racing shoes can greatly affect performance. The purpose of this study is to metabolically and mechanically compare the consumer version of the Nike Vaporfly 4% shoe to two other popular marathon shoes, and determine differences in running economy. Nineteen subjects performed two 5-minute trials at 4.44m/s wearing the Adidas Adios Boost (AB), Nike Zoom Streak (ZS), and Nike Vaporfly 4% (VP) in random order. Oxygen uptake was recorded during minutes 3–5 and averaged across both shoe trials. On a second day, subjects wore reflective markers, and performed a 3-minute trial in each shoe. Motion and force data were collected over the final 30 seconds of each trial. VP oxygen uptake was 2.8% and 1.9% lower than the AB and ZS. Stride length, plantar flexion velocity, and center of mass vertical oscillation were significantly different in the VP. The percent benefit of the VP over AB shoe was predicted by subject ground time. These results indicate that use of the VP shoe results in improved running economy, partially due to differences in running mechanics. Subject variation in running economy improvement is only partially explained by variation in ground time. 相似文献

运用问卷调查、文献资料和数理统计等研究方法,对湖南省第七届少数民族运动会高脚竞速运动员在训练、比赛中所产生的运动损伤情况进行追踪调查与分析。结果表明,高脚竞速主要损伤部位是手掌、拇指内侧、膝关节、足趾、踝关节及大小腿肌肉群等。分析认为,准备活动不充分、技术不正确或不熟练、运动负荷过大、身体疲劳、场地器材的不适合等是造成损伤的主要原因。建议从运动训练学、运动医学角度进行防治,最大限度地减少其发生率,将有助于高脚马运动水平的不断提高。 相似文献

A method aimed at the development of an America’s Cup racing yacht bulb is developed and validated against experimental data.
The method relies heavily on Reynolds Averaged Navier Stokes computational fluid dynamics (CFD) and also factors in gravitational
and aerodynamics effects through the use of a Velocity Prediction Program. Initial extensive use of towing tank results is
made to be able to validate the CFD solution and thus develop a solid ground for predictive work. Then, in order to narrow
down the focus on bulb developments, decoupled hypotheses are made on the influence of the hull and free surface wave. The
development of a detailed performance analysis chart of a known base bulb allows the use of a relatively small series of CFD
simulations together with physical hypotheses to assess any given bulb performance relative to the known base. The discussion
of the results on a specific development highlights the promises and limitations of the method; final full scale results are
discussed and analysed as well. 相似文献
