帆船运动主要是靠风在帆上产生动力而推动船前进的运动项目,风是帆船运动最主要的条件。本文采用实验研究的方法,探索了伦敦奥运会帆船竞赛区域的风的特征,为我国帆船运动员徐莉佳在奥运比赛中有效地利用风和正确选择航线提供了有力的保障。 相似文献

帆船项目与赛艇项目均为有氧项目,对于运动员有氧能力训练都非常重视。目前帆船项目还没有适合自身项目规律的测功仪,帆船的体能测试指标还相对较少,尚未建立体能评价体系。使用赛艇测功仪对国家队帆船470级运动员进行体能测试,验证使用赛艇测功仪作为帆船运动员体能测试手段的可行性,进而分析两个项目对体能需求的相关性,对1998年以来国内外国家队和部分省队的多名优秀女子赛艇公开级与轻量级运动员进行赛艇CONCEPT II测功仪的60min功率测试,并运用文献资料法、系统分析法、实验研究与观察法等将测试结果与赛艇女子运动员进行分析比较。从测试的结果来看,两个项目在有氧能力与无氧能力之间的比例关系非常的接近,说明两者在体能结构上具有一定的相似性。由于赛艇与帆船在体能结构方面的相似性,借助于赛艇项目非常完备的测功仪测试数据,通过统计和分析赛艇体能结构,可促进完成帆船相关评价体系的建立。 相似文献

In search of key-performance predictors in sailing, we examined to what degree visual search, movement behaviour and boat control contribute to skilled performance while rounding the windward mark. To this end, we analysed 62 windward mark roundings sailed without opponents and 40 windward mark roundings sailed with opponents while competing in small regattas. Across conditions, results revealed that better performances were related to gazing more to the tangent point during the actual rounding. More specifically, in the condition without opponents, skilled performance was associated with gazing more outside the dinghy during the actual rounding, while in the condition with opponents, superior performance was related to gazing less outside the dinghy. With respect to movement behaviour, superior performance was associated with the release of the trimming lines close to rounding the mark. In addition, better performances were related to approaching the mark with little heel, yet heeling the boat more to the windward side when being close to the mark. Potential implications for practice are suggested for each phase of the windward mark rounding. 相似文献

An assessment of the strength of knots and splices used as eye terminations in a sailing environment 总被引：1，自引：0，他引：1
Research into knots, splices and other methods of forming an eye termination has been limited, despite the fact that they
are essential and strongly affect the performance of a rope. The aim of this study was to carry out a comprehensive initial
assessment of the breaking strength of eye terminations commonly used in a sailing environment, thereby providing direction
for further work in the field.
Supports for use in a regular tensile testing machine were specially developed to allow individual testing of each sample
and a realistic spread of statistical data to be obtained. Over 180 break tests were carried out on four knots (the bowline,
double bowline, figure-of-eight loop and perfection loop) and two splices (three-strand eye splice and braid-on-braid splice).
The factors affecting their strength were investigated. A statistical approach to the analysis of the results was adopted.
The type of knot was found to have a significant effect on the strength. This same effect was seen in both types of rope construction
(three-strand and braid-on-braid). Conclusions were also drawn as to the effect of splice length, eye size, manufacturer and
rope diameter on the breaking strength of splices. Areas of development and further investigation were identified. 相似文献

从<明实录>中郑和第一次下西洋前夕有关造海船的记载、历史上福船在远洋航行和海战威力方面所居优势地位以及明初福建海防和造船业格局等诸方面分析,福船应是第一次下西洋的主要船型.而与郑和同时为中官、且在洪熙、宣德中曾四次奉敕出使琉球的柴山亦称自己所乘福船型册封舟为"宝船".由此可以认为,同为福船的宝船与册封舟只是一物二名而已.因此,我们将较可信的静海寺残碑和<前闻记>下西洋题本摘要中有关郑和船只的记载,与明朝后期册封琉球使臣们所撰<使琉球录>中关于册封舟形制的详细描述相结合并加以研究,相信有助于人们对郑和宝船获得符合客观实际的认识. 相似文献

ABSTRACTThis article explores, from a personal perspective, ageing and adventure in the context of the outdoor environment. Employing an autoethnographic sensibility, and drawing on fields of positive psychology, life course development, Outdoor and Adventurous Learning, and leisure studies, the paper discusses a range of motivations that contribute to my personal pursuit of a ‘fulfilled life’ now and in the future through ‘marine adventuring’. Adventuring is used to refer to my engagement with challenging physical outdoor activities; but also to my pursuit of learning; and, moreover, in my ‘existential’ quest for meaning. The specific activities under consideration are: seakayaking, SCUBA-diving and sailing. 相似文献
