上海世界游泳锦标赛中国队成绩分析 总被引：1，自引：1，他引：0
采用录像观察法等对2011年上海世界游泳锦标赛中外优秀运动员的成绩进行统计,分析中国队的优势和不足。主要结论:我国男子中长距离自由泳优势明显,其他项目竞争力较差;我国女子蝶泳、仰泳、混合泳和接力项目具有较强的竞争力,自由泳和蛙泳实力不足。建议继续采取措施力保优势项目(男子800m、1500m自由泳,女子200m蝶泳等),加强潜优势项目(男子400m自由泳,女子100m蝶泳、100m仰泳、200m混合泳及接力项目),着力提高年轻运动员的水平。 相似文献

通过多年系统的游泳比赛技术监测采集游泳比赛途中游各项技术数据,以世界综合排名前100名运动员成绩为划分依据,研究女子100m蛙泳、200m自由泳运动员途中游分段速度、划幅、划频、游速的特点。研究结果显示:在女子100m蛙泳和200m自由泳中,世界优秀运动员均呈现快划频的趋势;在对成绩预测中,通过运动员的划幅、划频比较容易预测运动员成绩增长情况和上升空间,即在成绩相同情况下,运动员划频慢,成绩提高幅度大;对10名优秀女子100m蛙泳运动员的途中游个性研究和多年成绩分析表明,她们划幅、划频的个性特征非常明显,蛙泳优秀运动员相对集中,运动员年限也长;在对女子200m自由泳优秀运动员的途中游个性研究和多年成绩分析结果表明,与蛙泳不同,200m自由泳运动员个性化不是非常明显,优秀运动员相对保持高水平成绩年限少,运动员分散,说明自由泳运动员的各种能力和水平更趋于一致,优秀运动员保持高水平的能力要求更高;蛙泳对运动员的身高要求最少,而技术要求最高,是适合亚洲人的一项运动;运动员出成绩后保持高水平年限长,符合经济学原理;蛙泳项目一直是亚洲的强项和我国的传统优势项目。 相似文献

1500米自由泳是竞技游泳项目中距离最长的项目。运动员在各分段中速度变化的具体表现能够客观反应其比赛战术。本文运用文献分析法、录像观察法对北京奥运会和山东全运会1500米自由泳决赛运动员的战术进行分析和探讨,分析得出长距离游泳战术类型分为前慢后快、前快后慢、相随、匀速和变速共五种战术。前慢后快战术和变速战术是世界级游泳运动员的常规战术之一。我国游泳运动员应加强后半程的游进能力,加强战术模拟训练,提升赛扬的战术执行能力。 相似文献

The pacing behaviors used by elite athletes differ among individual sports, necessitating the study of sport-specific pacing profiles. Additionally, pacing behaviors adopted by elite runners differ depending on race distance. An “all-out” strategy, characterized by initial rapid acceleration and reduction in speed in the later stages, is observed during 100 m and 200 m events; 400 m runners also display positive pacing patterns, which is characterized by a reduction in speed throughout the race. Similarly, 800 m runners typically adopt a positive pacing strategy during paced “meet” races. However, during championship races, depending on the tactical approaches used by dominant athletes, pacing can be either positive or negative (characterized by an increase in speed throughout). A U-shaped pacing strategy (characterized by a faster start and end than during the middle part of the race) is evident during world record performances at meet races in 1500 m, 5000 m, and 10,000 m events. Although a parabolic J-shaped pacing profile (in which the start is faster than the middle part of the race but is slower than the endspurt) can be observed during championship 1500 m races, a negative pacing strategy with microvariations of pace is adopted by 5000 m and 10,000 m runners in championship races. Major cross country and marathon championship races are characterized by a positive pacing strategy; whereas a U-shaped pacing strategy, which is the result of a fast endspurt, is adopted by 3000 m steeplechasers and half marathoners. In contrast, recent world record marathon performances have been characterized by even pacing, which emphasizes the differences between championship and meet races at distances longer than 800 m. Studies reviewed suggest further recommendations for athletes. Throughout the whole race, 800 m runners should avoid running wide on the bends. In turn, during major championship events, 1500 m, 5000 m, and 10,000 m runners should try to run close to the inside of the track as much as possible during the decisive stages of the race when the speed is high. Staying within the leading positions during the last lap is recommended to optimize finishing position during 1500 m and 5000 m major championship races. Athletes with more modest aims than winning a medal at major championships are advised to adopt a realistic pace during the initial stages of long-distance races and stay within a pack of runners. Coaches of elite athletes should take into account the observed difference in pacing profiles adopted in meet races vs. those used in championship races: fast times achieved during races with the help of one or more pacemakers are not necessarily replicated in winner-takes-all championship races, where pace varies substantially. Although existing studies examining pacing characteristics in elite runners through an observational approach provide highly ecologically valid performance data, they provide little information regarding the underpinning mechanisms that explain the behaviors shown. Therefore, further research is needed in order to make a meaningful impact on the discipline. Researchers should design and conduct interventions that enable athletes to carefully choose strategies that are not influenced by poor decisions made by other competitors, allowing these athletes to develop more optimal and successful behaviors. 相似文献

Energy system contribution to 1500- and 3000-metre track running 总被引：1，自引：0，他引：1
The aim of the present study was to quantify the contributions of the aerobic and anaerobic energy systems to 1500- and 3000-m track running events during all-out time-trials performed individually on a synthetic athletic track. Ten 3000-m (8 males, 2 females) and fourteen 1500-m (10 males, 4 females) trained track athletes volunteered to participate in the study. The athletes performed a graded exercise test in the laboratory and two time-trials over 1500 or 3000 m. The contributions of the energy systems were calculated by measures of race oxygen uptake, accumulated oxygen deficit (AOD), race blood lactate concentration, estimated phosphocreatine degradation and some individual muscle metabolite data. The relative aerobic energy system contribution (based on AOD measures) for the 3000 m was 86% (male) and 94% (female), while for the 1500 m it was 77% (male) and 86% (female). Estimates of anaerobic energy expenditure based on blood lactate concentrations, while not significantly different (P > 0.05), were generally lower compared with the AOD measures. In conclusion, the results of the present study conform with some recent laboratory-based measures of energy system contributions to these events. 相似文献

During water polo matches, players use different front crawl styles. The purpose of this study was to conduct a kinematic analysis of three water polo front crawl styles: front crawl with head under water, front crawl with head above water, and front crawl when leading the ball. Ten proficient water polo players performed 3 × 15 m sprints in each front crawl style, which were recorded three-dimensionally by two surface and four underwater cameras. The results showed no differences in performance and several kinematic characteristics among the water polo front crawl styles. However, front crawl when leading the ball showed shorter stroke length and greater stroke frequency. Front crawl with head underwater presented greater maximal finger depth and elbow angle at mid-stroke position. Front crawl with head above water and when leading the ball showed greater trunk obliquity and maximal depth of right and left foot, and shorter kick stroke frequency. The findings suggest that proficient players learn to master front crawl with head above water to achieve top velocity. Despite the common use of the front crawl with head underwater as the basis for water polo fast displacement, coaches should emphasize the use of the specific water polo styles to attain high performance. 相似文献
