【摘要】：本文通过使用Kistler系统提供的技术分析软件及配套设施作为支持,对我国现代五项国家队运动员男、女共9人进行了自由泳出发的拍摄,并通过录像分析法结合相应数据进行分析。结合文献资料、专家访谈的内容,针对我国现代五项国家队运动员在游泳出发方面存在的问题分出发离台阶段、入水阶段、水下滑行阶段和出水阶段制定陆上、水上及水陆结合的训练方法。训练内容包括陆上身体快速成出发流线型练习、陆上纵跳练习、直立入水练习、跪姿平台出发练习、跪姿出发台出发练习、出发静止水下滑行练习、水中直立蝶泳腿练习、出发接水下腿练习、水下腿衔接出水动作练习。通过以上技术练习后对测试运动员自由泳出发进行优化后测试并对比优化前数据及影像,得出以下结论。1.结论1.1通过对我国现代五项运动员在出发起跳阶段制定的优化方案实施针对训练后,运动员在出发姿势、起跳方向和起跳时身体流线型有所改观,神经反应时、出发反应时和离台角度都有所提高。但出发水平速度方面针对性练习还有待加强。1.2我国现代五项运动员在入水阶段有较大的提升,通过实施对运动员入水阶段问题指定的针对性训练后,运动员对身体的控制能力有所增强。入水距离、入水口直径与入水得到改善。入水速度、头部入水深度和最深距离也更符合我国现代五项运动员的自身提点。1.3我国现代五项运动员在出发滑行阶段保持身体流线型姿态都有较大提高,对身体的控制能力也有所增强。但是水下海豚腿依然是我国现代五项运动员较为薄弱的一个环节。1.4我国现代五项运动员在出水阶段对出水距离的控制能力有了较为明显的提高,出水阶段所产生的问题也得到了改善,出水衔接自由泳动作节奏也更加连贯。1.5在进行出发技术优化练习中应注意运动员自身特点和项目特征,选择最适合运动员的优化练习方法,能够获得良好的训练效果。1.6通过我国现在五项运动员与精英运动员数据相对比,优化后数据更加接近精英运动员,但与精英运动员数据仍有一定的差距。可见我国现代五项运动员在出发阶段仍有较大的提升空间,应继续加以巩固提高。
[Abstract]:In this paper, by using the Kistler system to provide technical analysis software and facilities as support for our modern five national team athletes male female, a total of 9 people were starting to shoot freestyle, and analyzed with the corresponding data through video analysis. Combined with the literature, expert interviews, aiming at Modern China five national team athletes in swimming of problems starting from Taiwan, into the water, water and water under the coasting stage stage of development of land, water and land based training methods. The training included upper body of land quickly streamlined practice land P-wave jumping exercises, exercises straight into the water, kneeling the platform of practice, kneeling block start practice of static underwater gliding exercises, vertical stroke exercises, starting with water leg exercises, underwater leg cohesion practice. Through the above water movement After the test of practice of Freestyle athletes after optimization test and contrast optimized data and images, draw the following conclusions through the conclusion of the 1.1.1. optimization scheme for our modern five athletes in the take-off stage of development for the implementation of training, athletes in the starting position, direction of take-off and take-off when streamlining has changed, nerve reaction time, reaction time and departure angle are improved. But the level of speed in practice has to be strengthened in China.1.2 modern five athletes have a larger increase in the entry stage, through the implementation of specified athletes into the water phase of the targeted training, the control ability of athletes on the body are enhanced. Into the water inlet diameter and the distance into the water were improved. Water speed, water depth and the distance deep into the head also conforms to our country modern five athletes Some of China's modern.1.3 own five of the athletes in the coasting stage to keep the body streamlined position are greatly improved, but also enhanced the ability to control the body. But the underwater dolphin kick is still.1.4 a part of China's modern five athletes is relatively weak in modern China five athletes in the stage of the ability to control the water outlet the distance is improved obviously, the problem caused by water phase is also improved, the water cohesion freestyle rhythm also more coherent.1.5 in technology optimization of athletes attention to their own characteristics and project characteristics should exercise, choose the most suitable for the optimization of athletes training methods can be obtained through the good training effect.1.6 China is now the five athletes and elite athletes data comparison, the optimized data is more close to elite athletes, but there is still data and elite athletes There is a certain gap. It is obvious that the five athletes in our country still have more room for promotion in the starting stage, and should be continued to be consolidated and improved.
