在汉城奥运会赛艇比赛中,苏联14条参赛艇中只有10艇进入了决赛,仅获得女子四人双桨和男子八人艇项目的银牌和男子双人双桨的铜牌。因此,在四年一度的奥运会新周期训练的开始阶段,我们有必要对失利的技术原因进行一些客观地分析研究。 相似文献

采用SIMIMotion运动分析系统,对中、外赛艇女子单人双桨项目(W1X)优秀运动员一个完整划桨周期技术进行分析。结果表明:中国赛艇W1X优秀运动员在划桨技术周期的艇速、划距指标上与国外W1X优秀运动员有显著性差异(P<0.05),推拉桨时间、桨角和各关节角度指标没有显著性差异(P>0.05)。中国赛艇W1X运动员的推拉桨时间、划桨身体姿势比较合理,建议在保持推桨动力的基础上,借鉴国外赛艇W1X优秀运动员低桨频高稳速划桨的技术,缩短与世界级赛艇W1X优秀运动员的差距。 相似文献

优秀女子赛艇运动员划桨动作的运动学特征研究 总被引：3，自引：0，他引：3
运用德国SIMI°Motion7.50运动分析系统对2007年世界锦标赛赛艇女子单人双桨运动员途中划技术进行二维录像解析,探讨优秀女子赛艇运动员划桨动作的运动学特征。研究发现,一桨周期内,由于运动员身体前倾程度以及桨叶入水角度不一,运动员间以髋关节和肩关节的活动范围差异较大。运动员拉桨初期注重腿部推蹬,躯干不能过早伸展;拉桨后期要求躯干至上肢关节协调发力。回桨阶段运动员肩肘关节和躯干最大角速度几乎同时达到,上肢关节衔接技术要求较高,腿部处于放松状态,不参与发力。躯干在整个回桨过程中基本保持匀速运动状态。 相似文献

中国赛艇优秀男子轻量级运动员技术特征分析 总被引：3，自引：1，他引：2
通过研制的赛艇实船力量测试系统对我国优秀男子轻量级运动员技术特点进行了测试分析。结果表明该系统为科学地评定、改进和完善赛艇技术提供了强有力的工具。目前我国男子轻量级多人艇技术配合上的主要问题是身体移动、停止、再启动时机不一致，身体的整体重心回位不够及时，另外，桨叶入水时拉桨不够迅速、圆滑，腿部蹬力过大。经过测试分析以后，包括老运动员在内，技术动作得到明显的改进和完善。 相似文献

对黄胜初于2000年建立的双动力赛艇动力学方程进行矢量推导,结果显示,在操桨过程中人体质心的移动产生无击水动力。据此,认为国际赛艇联合会(FISA)赛艇教练员培训手册(2002年版)中,单动力赛艇动力模型衍生出的三点错误之处。研究认为,国内生物力学界和赛艇界对赛艇动力学及其在训练中的应用存在认识上的误区。应注重回桨技术的研究和训练,降低1桨中拉推桨时间比,提高1桨的划桨效率。 相似文献

For a rowing crew to be successful, the movements of the rowers need to be well coordinated. Because rowers show individual force patterns, they have to adapt their movements when rowing as a crew. In this exploratory study, these hypothesized changes in movement pattern were examined. The force graphs of six elite coxless fours crews were recorded over 11 training runs using strain gauges attached to the oars. A detailed force analysis showed that form differences, but not area differences, between force patterns decreased when force output increased as a result of two different processes. First, increasing force output reduced form differences instantaneously by reducing the individual variation in force patterns. Secondly, the kinaesthetic perception of form differences is easier than that of area differences. This better perception facilitates the adaptation of movement patterns, especially when force output is high. 相似文献

Although it is clear that rowers have a large muscle mass, their distribution of muscle mass and which of the main motions in rowing mediates muscle hypertrophy in each body part are unclear. We examine the relationships between partial motion power in rowing and muscle cross-sectional area of the thigh, lower back, and upper arms. Sixty young rowers (39 males and 21 females) participated in the study. Joint positions and forces were measured by video cameras and rowing ergometer software, respectively. One-dimensional motion analysis was performed to calculate the power of leg drive, trunk swing, and arm pull motions. Muscle cross-sectional areas were measured using magnetic resonance imaging. Multiple regression analyses were carried out to determine the association of different muscle cross-sectional areas with partial motion power. The anterior thigh best explained the power demonstrated by leg drive (r2 = 0.508), the posterior thigh and lower back combined best explained the power demonstrated by the trunk swing (r2 = 0.493), and the elbow extensors best explained the power demonstrated by the arm pull (r2 = 0.195). Other correlations, such as arm muscles with leg drive power (r2 = 0.424) and anterior thigh with trunk swing power (r2 = 0.33 5), were also significant. All muscle cross-sectional areas were associated with rowing performance either through the production of power or by transmitting work. The results imply that rowing motion requires a well-balanced distribution of muscle mass throughout the body. 相似文献

赛艇运动员有氧能力的测试 总被引：6，自引：0，他引：6
以１４名女子赛艇运动员为受试者，分别在跑台、自行车和赛艇测功仪上以一次最大负荷和递增负荷方式对其进行了有氧能力测量。根据测量结果，作者建议赛艇测功仪是赛艇运动员最大吸氧量测量的首选负荷器；一次最大负荷更能准确地测出赛艇运动员的最大吸氧量；同时测出的实际耗氧量占最大吸氧量的百分比在评价赛艇运动员有氧训练水平时较ＶＡＴ、ＬＡＴ更有价值。 相似文献
