【摘要】：基于2022北京冬奥会的背景下,以我国速度滑冰运动项目的可持续发展为目的,对中、外优秀青年速度滑冰运动员1000米不同阶段速度变化特征进行对比,检测和诊断我国速度滑冰运动员体能的优势与缺陷,构建速度滑冰运动员不同阶段最佳的速度变化模式,为我国青年1000m速度滑冰运动员提供具有针对性的训练策略。以青年世界杯速度滑冰比赛中1000m速度滑冰比赛前6名的12名运动员(不包括中国队的运动员)和此次比赛中参与的6名中国青年运动员为测试对象。拟采用文献资料法、专家访谈法、速度解析法、对比分析法、数理统计法、逻辑分析法等研究分析了中、外优秀青年运动员速度滑冰运动员1000m不同阶段的速度变化特征。研究认为:(1)依据速度滑冰项目的生理学基础结,合1000m速度滑冰项目的代谢特点,认为当前1000m速度滑冰项目的阶段划分主要有两种,其一是将1000m划分为前段200m、中段400m和后段400m三个阶段;其二是将1000m划分为前段500m和后段500m两个阶段;(2)中、外优秀青年运动员在200-400-400阶段中的速度变化的特征可以概括为,前200m阶段中运动员速度变化大,中间400m阶段速度变化平稳,后400m阶段速度变化尽可能小,但中国青年运动员不仅表现出前程加速的不足,并且还表现出后程降速的严重性;(3)中国青年运动员在前500m阶段的速度变化规律表现为,急加速阶段、弯道过度加速阶段、直道缓慢加速阶段,速度变化呈间歇性急加速特征;后500m速度变化的规律表现为,在弯道阶段速度呈快速下降,直道阶段速度趋于平稳,后程降速呈阶梯式下降特征;(4)国外青年运动员在前500m阶段的速度变化规律表现为,起跑急加速阶段、弯道持续加速阶段,直-弯道缓慢加速阶段,速度变化呈持续性稳定加速特征;后程500m速度变化规律表现为,在弯道和直道阶段尽可能控制速度下降,后程降速呈控制式下降特征。
[Abstract]:Based on the background of the 2022 Beijing Winter Olympic Games, aiming at the sustainable development of the speed skating events in China, this paper makes a comparison between the Chinese and foreign outstanding young speed skaters in the different stages of the speed change of 1000 meters. To detect and diagnose the advantages and disadvantages of the physical ability of Chinese speed skaters, to construct the best speed changing mode of speed skaters in different stages, and to provide targeted training strategies for the young Chinese speed skaters at 1000m speed. 12 top 6 athletes (excluding Chinese athletes) in the 1000m speed skating competition in the Youth World Cup speed skating competition and 6 young Chinese athletes in this competition were taken as the test subjects. This paper studies and analyzes the speed variation characteristics of young Chinese and foreign elite speed skaters at different stages of 1000m by means of literature, expert interview, speed analysis, comparative analysis, mathematical statistics, logic analysis, and so on. The results are as follows: (1) according to the physiological foundation of speed skating and the metabolic characteristics of 1000m speed skating, it is considered that there are two main stages of 1000m speed skating. The first is to divide 1000m into three stages: 200m in the front segment, 400m in the middle segment and 400m in the rear segment; the other is that 1000m is divided into two stages: 500m in the front segment and 500m in the rear segment; (2) the characteristics of the speed changes of the outstanding young athletes in the 200-400-400 stage can be summarized as follows: In the first 200m stage, the speed of the athletes changed greatly, the speed of the middle 400m stage changed steadily, and the speed of the latter 400m stage changed as little as possible. However, the young Chinese athletes not only showed the deficiency of the acceleration of the future. And it also shows the severity of the slow down in the later stage. (3) the speed changes of the young Chinese athletes in the first 500m stage are as follows: the rapid acceleration stage, the excessive acceleration stage of the curve track, the slow acceleration stage of the straight track, and the speed change is intermittent and rapid acceleration characteristic; The law of the speed variation of the back 500m is as follows: the velocity decreases rapidly in the curve stage, the velocity tends to be stable in the straight track stage, and the slow down speed in the later stage shows the characteristics of step descent; (4) the velocity variation law of the young athletes from abroad in the first 500m stage is as follows: The change of velocity of 500m speed at the end of the course is as follows: controlling the speed decrease as far as possible in the curve and the straight track, in the rapid acceleration stage of the starting course, in the continuous acceleration stage in the bend, in the slow acceleration stage of the straight bend, in the slow acceleration stage of the straight bend, Late-course deceleration is a controlled descent.
