反身翻腾类动作是由助跑、起跳、向后翻转、看目标、打开、入水6个环节组成的跳水空翻动作，这类动作要求运动员在背对起跳点做向后翻腾动作的情况下，通过本体感觉控制离台的距离和高度，以便安全地完成动作，因此，对运动员的本体感觉、动作技术和心理素质三方面的能力有较高的要求，这不但增加了稳定完成动作的难度，而且还比其它类型的动作增加了危险性。 相似文献

跳水运动对我們的神經、肌肉,特別是高級神經系統及人体各部的分析器——特別是前庭分析器和本体感受器,都具有特別重要的訓練意义。同时对发展运动員身体素質的灵敏、速度、耐力、勇敢、机智、頑强、意志、品質等,都起着重要作用。跳水动作大致可分成,助跑、起跳、空中动作入水,每一过程都是密切相关,不可分割的完整动作的一部份,以下我談談入水动作。一、在我的日常訓練过程中,特別是入水动作作得很差,因而影响了整个动作的成績。那末入水动作在整个跳水动作过程中有何重要意义呢? 相似文献

臂立向后翻腾加转体类动作是05年国际新规则调整难度系数后，跳台跳水难度发展选择的一个新动向。选择这个发展方向的主要动因有三：第一、该类动作比臂立向前翻腾转体动作在学习上更容易掌握；第二、该类动作更有发展空间：第三、难度系数值大于臂立向前翻腾转体类动作。在06年上半年冠军赛中有5人比较好的掌握了6245d动作，其中广东跳水有一人掌握，说明在这类动作的发展方面，广东跳水有进一步发展的潜力空间。 相似文献

Abstract This article presents a method to analyze the scoring of judges in springboard diving by identifying some of the components of a dive which are useful in predicting the scores of the judges. A videotape recording of 26 divers doing the front dive half-twist was made at the 1979 men's A.A.U. prequalifying meet, held at Ohio State University. The method of measurement involved the use of clear plastic grids placed over the video monitor. The maximum height of the diver above the board, distance out from the board, size and duration of splash, numerous body angles at various times during the dive, as well as deviation of twist from 180 degrees were measured. A Stepwise Multiple Regression program was used to generate a prediction equation using a subset of these variables which would best predict the total score of the judges for each dive. The equation generated included height, distance, twist, and lower body angle at the point when the diver's head was opposite the board; the equation predicted the scores of the judges with a multiple correlation coefficient R = .80. The particular variables identified would of course be different for other types of dives, and might very well differ for a new set of data for the front dive half twist. However, the method presented provides the diving community with a procedure for identifying some of the components in a particular dive that partially explain what is in the judge's mind. 相似文献

AbstractTwo distinctly separate training facilities (dry-land and aquatic) are routinely used in springboard diving and pose an interesting problem for learning, given the inherent differences in landing (head first vs. feet first) imposed by the different task constraints. Although divers may practise the same preparation phase, take-off and initial aerial rotation in both environments, there is no evidence to suggest that the tasks completed in the dry-land training environment are representative of those performed in the aquatic competition environment. The aim of this study was to compare the kinematics of the preparation phase of reverse dives routinely practised in each environment. Despite their high skill level, it was predicted that individual analyses of elite springboard divers would reveal differences in the joint coordination and board-work between take-offs. The two-dimensional kinematic characteristics were recorded during normal training sessions and used for intra-individual analysis. Kinematic characteristics of the preparatory take-off phase revealed differences in board-work (step lengths, jump height, board depression angles) for all participants at key events. However, the presence of scaled global topological characteristics suggested that all participants adopted similar joint coordination patterns in both environments. These findings suggest that the task constraints of wet and dry training environments are not similar, and highlight the need for coaches to consider representative learning designs in high performance diving programmes. 相似文献

Abstract Recreational diving has developed extensively over the years, becoming a popular sport and leisure activity, attracting millions of people around the world. A questionnaire aiming to identify problematic stages during recreational diving and to map the relative importance of the diving equipment features was distributed among divers of different genders, ages, certification, and professional experience (N=130). It was found that the most problematic stages for recreational divers (out of 32 tasks) were on-land activities and transitional phases between water and terrestrial interfaces: carrying equipment on shore, underwater orientation, exiting from water to boat and reef, surface swimming, and donning the wetsuit. Safety/reliability, individual adjustment, performance, and simplicity were rated the most important features for diving equipment, while design/style and brand name were rated the least. We suggest that redefinition of the task, equipment, and environment according to the current profile of recreational divers will increase pleasure, reduce fatigue and related diving accidents, improve safety, and increase the number of dedicated active divers. 相似文献

Abstract An investigation of personal autonomy levels as measured by the Pensacola Z scale was conducted on 147 scuba diving trainees at the University of California at Los Angeles. The study was part of an effort to develop insight into selection and training procedures for reliable underwater workers. Findings revealed that diver trainees described themselves as individualistically as did groups of astronauts and Antarctic scientists, but their Z-scale scores were not significantly different from other campus groups. Further, the Z-scale did not significantly differentiate between successful trainees and dropouts in the course. A weak relationship was found between the Z-scale score and scuba diving performance during pool testing. It was concluded that the qualities measured by the Z-scale test may be more important to the future diving careers of the subjects than to their selection and training. 相似文献
