削球打法在乒乓球技术发展的不同时期,为我国健儿攀登世界高峰立下了汗马功劳,对推动中国和世界乒乓球运动的发展起到积极作用。据统计,从1960—1995年的35年间,中国女子削球运动员参加的世界乒乓球锦标赛中,有15人次获得前3名的佳绩,共夺得29块奖牌,这足以证明女子削球打法曾经占有的主导地位和所起的重要作用。 相似文献

目的:采用Meta分析的方法探讨血管紧张素Ⅰ转换酶(ACE)基因插入/缺失(I/D)多态性与中国运动员运动能力的关联性.方法:系统地检索PubMed、EMbase、CNKI、CBM、VIP、WanFang data中有关ACE I/D基因多态性与中国运动员运动能力关联性的病例—对照研究,检索时间均为建库至2015年8月1日.由2位研究者按纳入和排除标准独立筛选文献、提取数据,采用Stata12.0软件进行Meta分析.结果:共纳入15个病例—对照研究(含17个比较).Meta分析结果显示,ACE I/D基因多态性与中国运动员运动能力的关联性在所有基因模型比较中均无统计学意义.根据不同运动类型进行亚组分析显示,ACE DD基因型及D等位基因与力量型、耐力型运动能力的关联性有统计学意义,与游泳类无统计学意义.敏感性分析结果表明结果稳定性较好,漏斗图结果显示各基因模型比较均不存在发表偏倚.结论:ACE DD基因型和D等位基因与中国力量型运动员运动能力呈正相关,与耐力型运动能力呈负相关,与游泳类运动能力不相关. 相似文献

The goal of this research was to develop a method to quantify the dynamic strain profile (DSP) of an ice hockey stick shaft and assess the potential influence of player skill and stick shaft stiffness on DSP during slap (SS) and wrist shots (WS). Seventeen adult males performed shots with two different stick stiffness’ on synthetic ice. Subjects were subdivided as high (HC) and low calibre (LC). Dependent measures included strain measures from five strain gauge pairs along the shaft length recorded at 10 kHz. In general, this approach was sufficiently sensitive to clearly distinguish between shot types (strains SS > WS), player calibre (strains HC > LC) and stick models (strain flex77 > flex102) as well as to identify within stick deflection differences along the shaft. This strain based analysis has a time and spatial resolution undetected by common motion capture based systems. 相似文献

The purpose of this study was to examine the three-dimensional movement profile of the blade during a stationary slap shot,
as a function of player skill level. A total of 15 subjects participated; eight were classified as elite and the remaining
seven were recreational. Performances were evaluated by simultaneously recording the movements of the stick’s lower shaft
and blade with high-speed video (1000 Hz), the time of stick-ground contact with two uniaxial forceplates and time of blade-puck
contact with a uniaxial accelerometer mounted within the puck. Data were analysed with a two-way MANOVA for several dependent
variables including linear kinematics, temporal phase data and global angles. The results indicated that skill level affected
blade kinematics, with elite shooters tending to alter timing parameters (i.e. phase length), magnitude of linear variables
(i.e. displacement, etc.) and the overall blade orientation to achieve a higher velocity slap shot. These analyses identified
a unique ‘rocker’ phase within the execution of the slap shot in both groups. 相似文献

The performance of the ice hockey slap and wrist shots: the effects of stick construction and player skill 总被引:1,自引:0,他引:1
The purpose of this study was to examine the interaction of players’ skill level, body strength, and sticks of various construction
and stiffness on the performance of the slap and wrist shots in ice hockey. Twenty male and twenty female subjects were tested.
Ten of each gender group were considered skilled and ten unskilled. In addition to general strength tests, each subject performed
the slap and wrist shots with three stick shafts of different construction and stiffness. Shot mechanics were evaluated by
simultaneously recording ground reaction forces from a force plate, stick movement and bending from high speed filming and
peak puck velocity from a radar gun. Data were analysed with a 4-way repeated measures ANOVA for several dependent variables
including peak puck velocity, peak Z (vertical) force, peak bending and stick to ground angles, peak angular deflection of
the shaft, and hand placement on the stick. The results indicated that: 1) the slap shot was much faster than the wrist shot
corresponding to greater vertical loading force, stick bending, and greater width of the hand placement; 2) the puck velocity
was influenced by skill level and body strength but not stick type; and, 3) that skilled players were able to generate more
vertical force and bend of the stick, in part, by adjusting their hand positions on the stick. Further studies are needed
to address the specific influence of body strength and skill on the techniques of these shots and in relation to stick material
and construction properties. 相似文献

Hockey sticks have undergone a dramatic transformation from wood to aluminum to composite in just over the past 20 years. With the introduction of different materials, there has been increasing interest in how the material properties affect shot speed. This study examined the effects of stick stiffness from measured swing motion on puck speed. Stick evaluation involved a six amateur player study, quasi-static stiffness measurement, video motion analysis, and numerical simulation. The effect of stiffness on puck speed was observed to depend on shot type. For shots involving large stick loading, as occurs with a slap shot, puck speed decreased as stick stiffness increased. The trend was consistent with a constant force player model. For shots involving low stick loading, as occurs with a wrist shot, puck speed increased as stick stiffness increased. The trend was consistent with a constant displacement player model. Finite element simulation of the slap shot agreed generally with the results of the player study and was used to find an optimal loading distance (distance that the stick contacts the ice prior to the puck) to be 24 cm. 相似文献
