短跑是人的运动技能和各种素质在运动过程中综合性的表现。它是灵敏性的项目。要提高短跑水平,必须提高跑的频率,加大跑的步幅,增强蹬摆腿的力量,提高摆臂的速度和重心的稳定移动。这诸多方面的内容,对一般中学田径运动队的训练方法提出了综合性和统一性的要求。对此,我曾在学校的业余训练采用了“循环训练法”和“强力训练法”,取得了可喜的效果。循环训练法:在400米跑道上,按60米中速跑——40米侧身交叉跑——80米大步跑——20米小步跑——50米全速跑——30米慢跑——100米加速跑——20米放松走的顺序返回(中间不休息)为一个循环,强度为 相似文献

在短跑教学中，一些教师强调跑动中的伸膝、伸髌及下肢的蹬伸能力，旨在增大步幅，提高短跑速度，却往往忽视了摆动效果和整体运动环节的协调配合，易造成身体身心在垂直方向的波动加大，降低整体水平运动的效果，影响水平运动速度的发挥和高速跑中的放松技术。现代短跑技术应视为以髋为轴的高速摆动－－平动运动，这是短跑运动和短跑技术的本质特征。相互信任在教学中强调髋关节的灵活性和协调性，跑动中的肌肉放松和整体运动环节的协调配合，提出了用“用髋跑”技术，通过增大步幅来提高短跑的速度，收到较好的教学效果，现介绍给大家。 相似文献

Exercise is a potent stimulus for the release of human growth hormone (hGH), but the time course of the hGH response to sprint exercise has not been studied. The aim of the present study was to determine the time course of the hGH response to a 6 s and a 30 s maximal sprint on a cycle ergometer. Nine males completed two trials, on one occasion performing a single 6 s sprint and on another a single 30 s sprint. They then rested on a couch for 4 h while blood samples were obtained. Three of the participants completed a further control trial involving no exercise. Metabolic responses were greater after the 30 s sprint than after the 6 s sprint. The highest measured mean serum hGH concentrations after the 30 s sprint were more than 450% greater than after the 6 s sprint (18.5 +/- 3.1 vs 4.0 +/- 1.5 microg l(-1), P < 0.05). Serum hGH also remained elevated for 90-120 min after the 30 s sprint compared with approximately 60 min after the 6 s sprint. There was a large inter-individual variation in the hGH response to the 30 s sprint. In the control trial, serum hGH concentrations were not elevated above baseline at any time. It would appear that the duration of a bout of maximal sprint exercise determines the magnitude of the hGH response, although the mechanism for this is still unclear. 相似文献

In the control trial, serum hGH concentrations were not elevated above baseline at any time.

随着现代技术向体育的渗透,短跑技术也随之演变,现代短跑技术具有鲜明的时代性,主要表现在“大、快、前摆”的技术动作上,作为教师应了解这些结构特点,才能更合理、有效的指导教学,为适应现代短跑技术的掌握和成绩提高起到积极作用。因此,提高短跑运动水平具有重要意义。在实际训练中,经常产生影响和阻碍短跑成绩提高的令教练员十分棘手的“速度障碍”。只有研究和分析“速度障碍”的成因,采取切实有效的方法和手段来克服速度障碍,才能保证短跑运动水平的提高。 相似文献

The purpose of this study was to use three-dimensional methods to determine whether there are distinct kinematic differences between sprint and distance front crawl swimmers when swimming at a sprint pace. Seven sprint and eight distance specialists performed four 25-m sprints through a 6.75-m(3) calibrated space recorded by six gen-locked cameras. The variables of interest were: average swim velocity, stroke length, stroke frequency, upper limb and foot displacement, elbow angle, shoulder and hip roll angles, duration of stroke phases, and the time corresponding to particular events within the stroke cycle relative to hand entry. Differences between sprint and distance swimmers were assessed with an independent t-test for each variable, in addition to effect size calculations. Differences between sprint and distance front crawl swimmers were generally small and not significant when swimming at a sprint pace. Differences were limited to temporal aspects of the stroke cycle. These findings suggest that coaches should not train sprint and distance specialists differently in terms of technique development. 相似文献

This study used a mathematical model to examine the effects of the sled, the running surface, and the athlete on sprint time when towing a weighted sled. Simulations showed that ratio scaling is an appropriate method of normalising the weight of the sled for athletes of different body size. The relationship between sprint time and the weight of the sled was almost linear, as long as the sled was not excessively heavy. The athlete’s sprint time and rate of increase in sprint time were greater on running surfaces with a greater coefficient of friction, and on any given running surface an athlete with a greater power-to-weight ratio had a lower rate of increase in sprint time. The angle of the tow cord did not have a substantial effect on an athlete’s sprint time. This greater understanding should help coaches set the training intensity experienced by an athlete when performing a sled-towing exercise. 相似文献
