中外优秀110m栏运动员主要技术指标与成绩的灰色关联分析 总被引：1，自引：0，他引：1
运用文献资料调研、灰色关联度分析等方法,对中外优秀110m跨栏跑运动员主要技术指标与成绩的关系进行量化研究,结果显示：优秀110m栏运动员主要技术指标与成绩关联度排序是栏间3步的平均时间、冲刺平均速度、冲刺时间、保持最大速度经过栏的个数、起跑至H1速度、跨栏腾空时间平均值、最大分栏速度、平均分栏速度。同时发现栏间3步的平均时间、冲刺平均速度、冲刺时间3项指标是影响优秀110m栏运动成绩的关键技术指标。就此进行了探讨并提出了建议,对提高我国110m栏运动水平和科学化训练具有参考价值。 相似文献

田径男子110m栏项目是一项高难度的田径比赛项目,旨在测试运动员在短距离内的速度和技巧。比赛的跑道长度为110m,跨越10个栏架,每个栏杆高1.067m。运动员需要以最快的速度穿过每个栏杆,同时保持平衡和稳定。这项比赛对于运动员的反应速度、爆发力、协调性和耐力都有很高的要求[1]。男子110m栏项目在1896年第1届雅典现代奥林匹克运动会上被定为正式比赛项目之一。在我国,男子110m栏项目一直是田径运动中备受关注的项目之一,以刘翔为代表的中国男子110m栏运动员,以12.91s的成绩夺取了2004年雅典奥运会冠军,并在2006年以12.88s的成绩打破男子110m的世界记录。为我国跨栏项目取得了历史性辉煌成绩,我国运动员在国际比赛中也取得了很多优异的成绩[2]。经过数代人的顽强拼搏和积极探索我国男子100m栏运动员不断取得运动水平的提高和运动成绩的突破,到现阶段我国男子110m栏项目已具备世界先进水平。 相似文献

为揭示中外优秀男子110 m跨栏跑速度分配的本质,提高我国男子110 m跨栏跑运动成绩和改进训练方法提供科学依据,采用动态分析法对男子110 m跨栏跑进行全程分析。结果表明,中外优秀的跨栏运动员在第3栏-第5栏间速度最快并保持稳定,从跨过第6栏后开始逐渐减速,减速至第9栏前速度达最小,在第9栏到第10栏间又出现加速,然后高速冲刺至终点;运动员栏间跑速度快,会造成过栏腾空时间长;9个跨栏周期的平均速度是影响运动员能否夺冠的主要因素。 相似文献

Perception of effort, also known as perceived exertion or sense of effort, can be described as a cognitive feeling of work associated with voluntary actions. The aim of the present review is to provide an overview of what is perception of effort in Exercise Science. Due to the addition of sensations other than effort in its definition, the neurophysiology of perceived exertion remains poorly understood. As humans have the ability to dissociate effort from other sensations related to physical exercise, the need to use a narrower definition is emphasised. Consequently, a definition and some brief guidelines for its measurement are provided. Finally, an overview of the models present in the literature aiming to explain its neurophysiology, and some perspectives for future research are offered. 相似文献

国内外体育高校在专业设置方面有着同向异构的差别,即相同专业人才的知识与能力结构的设计有重大差异。这种差异主要体现在课程体系的结构上,具体表现为在课程结构的层次配置上,一般基础薄弱,专业基础窄。在课程结构的要素配置上,我国高等体育院校的课程体系有以下特征：重实践轻理论;重术轻学;重自然科学轻社会科学;重传统的竞技运动项目,轻非竞技类的体育技能;重知识传习轻能力培养;重直接经验轻间接经验;重深度轻广度;重必修轻选修。 相似文献

Abstract Photometric analysis of racing wheelchairs used by athletes at the 1980 Olympic Games for the Disabled, held at Arnham, Holland, was undertaken. Chairs were classified by the level of success achieved in them and by the distances over which they were raced. For each chair the position and orientation of the seat was measured, as were the length and the width of the wheelchair frame. In addition, mainwheel camber and handrim diameter were measured. Significant differences (at or beyond the .05 level) in wheelchair construction were recorded. The more successful wheelchairs were characterized by (1) lower seats, (2) the seat base at a comparatively higher angle to the horizontal, (3) narrower frame, (4) smaller handrims. The chairs used in distance events differed significantly from those used in sprints in (1) a more rearward placement of the seat, (2) lower placement of the seat, (3) longer chair frame and (4) narrower frame construction. 相似文献

Abstract One of the most fundamental skills on the pommel horse is double leg circles (circles). Circles can be performed on all parts of the pommel horse. It was hypothesized that the different sets of physical constraints of the apparatus require a gymnast to adapt circles technique. The purpose of this study was to quantify how gymnasts modify their technique during circles to accommodate different physical obstacles due to different support surfaces and body orientations. To investigate these adaptations, a comparison of the two most common circles on pommel horse – namely, circles in cross support (cross-circles) and circles in side support (side-circles) – was carried out. Seven elite male gymnasts performed three sets of 10 cross-circles and side-circles on a pommel horse. Three-dimensional coordinates were acquired using 12 Qualisys ProReflex motion tracking cameras operating at 120 Hz. Temporal characteristics, the motion of the centre of mass, and the body angles – flexion and lateral flexion – were analysed. We found that cross-circles took less time to complete a single circle (0.92±0.02 vs. 0.95±0.02 s), had a smaller ratio for the rear support phase (0.15±0.02 vs. 0.18±0.03), a narrower supporting-hand distance (0.33±0.03 vs. 0.52±0.00 m), greater flexion of the body over the rear support phase (44±12° vs. 27±8°), and less lateral flexion of the body over the single-hand support phase (entry: 20±5° vs. 35±3°; exit: 26±4° vs. 33±4°) than side-circles. Our results suggest that gymnasts adapt their technique to the physical constraints imposed by the shape of the pommel horse and the location and orientation of the circles. Cross-circles were characterized by a high rear support position with a narrower hand-spacing, which would require excellent shoulder flexibility and strength. Consequently, lack of these traits may explain the need for greater body flexion in cross-circles than in side-circles during rear support. Understanding the technical differences will facilitate an effective transfer of the technical similarities among different types of circles. 相似文献

"I spy with my little eye!": breadth of attention, inattentional blindness, and tactical decision making in team sports 总被引：1，自引：0，他引：1
Failures of awareness are common when attention is otherwise engaged. Such failures are prevalent in attention-demanding team sports, but surprisingly no studies have explored the inattentional blindness paradigm in complex sport game-related situations. The purpose of this paper is to explore the link between breadth of attention, inattentional blindness, and tactical decision-making in team ball sports. A series of studies revealed that inattentional blindness exists in the area of team ball sports (Experiment 1). More tactical instructions can lead to a narrower breadth of attention, which increases inattentional blindness, whereas fewer tactical instructions widen the breadth of attention in the area of team ball sports (Experiment 2). Further meaningful exogenous stimuli reduce inattentional blindness (Experiment 3). The results of all experiments are discussed in connection with consciousness and attention theories as well as creativity and training in team sports. 相似文献

This study assessed the effect of step width during running on factors related to iliotibial band (ITB) syndrome. Three-dimensional (3D) kinematics and kinetics were recorded from 15 healthy recreational runners during overground running under various step width conditions (preferred and at least ± 5% of their leg length). Strain and strain rate were estimated from a musculoskeletal model of the lower extremity. Greater ITB strain and strain rate were found in the narrower step width condition (p < 0.001, p = 0.040). ITB strain was significantly (p < 0.001) greater in the narrow condition than the preferred and wide conditions and it was greater in the preferred condition than the wide condition. ITB strain rate was significantly greater in the narrow condition than the wide condition (p = 0.020). Polynomial contrasts revealed a linear increase in both ITB strain and strain rate with decreasing step width. We conclude that relatively small decreases in step width can substantially increase ITB strain as well as strain rates. Increasing step width during running, especially in persons whose running style is characterized by a narrow step width, may be beneficial in the treatment and prevention of running-related ITB syndrome. 相似文献

竞技武术作为武术的重要组成部分,其在传播武术的过程中起着至关重要的作用。随着社会、经济的发展,竞技武术运动员的退役问题已亟待解决。通过调查已退役的高水平武术套路运动员148名,从中得知运动员对退役这一概念的认识及运动员的理想与需要。研究发现:我国现役运动员缺乏对退役的规划,就业目标较狭窄,往往集中在教师、教练员等岗位;运动员存在着训练和文化课学习时间冲突的问题,为取得好名次长时间的武术训练使得他们仅有较少的时间进行文化课的学习;运动员在退役后的转型期过渡期存在着心理上的不适应等。针对这些问题,提出相应对策,以期使高水平竞技武术套路运动员能搞顺利解决退役问题。 相似文献
