1侧踹腿堵击技术的特点作用在散打运动中,侧踹腿不光能起主动进攻,还具有重要防守的作用,能够给对手制造重击。侧踹腿堵击的运动形式与踹腿相同,由于它更强调快速,在实践中多以前侧踹腿踹击对方的腹部、头部等,由此可以破坏对手的进攻组合动作和有效距离。由于散打的技术在不断的提高,散打竞赛规则的变化比赛时运动员必须戴护头、穿护胸,从而加大了打击面积,侧踹腿堵击被运动员和教练员越来越重视。1.1技术特点侧踹腿的堵击的特点具有预兆小、启动快、力点准、方法巧,可在中、远距离攻击对手的正面部位。堵击侧踹腿由于加速时间稍长,力量大速度很快,非常适用于防守反击,主要用以向对方施以重击。在武术中常讲一句话:“你不动我不动,你欲动我先动”。当对手用低腿法打击我下肢时,第一反应就是迅速提膝防守,同时展髋踹出侧踹腿,成功完成防守反击技术。侧踹腿堵击时高可击头,中可击肋,下可击腿,其中击打最具有威力就是身体正面的面部、胸部、腹部、肋部、腿部等部位,侧踹腿广泛的攻击面和多样的变化主要取决于膝关节、髋关节和腿的柔韧性和灵活性,骼腰肌的力量同样也是制约侧踹腿力量的重要原因。2踹腿堵击的训练方法侧踹腿堵击的训练方法有很多,其中包括空击练习、实物练习、...  相似文献

Kinetic (3-D force plate), kinematic (videography) and temporal characteristics of backstroke turns by 20 male and 16 female swimmers were recorded to identify and describe key elements of backstroke turning performance. Data were recorded during a 50 m maximum effort swim in a 25 metre pool. A Pearson product moment correlation matrix revealed that the 5 m RTT was significantly correlated with anthropometric measures of height, mass, trochanteric height and age; kinetic measures of horizontal impulse and peak force; and kinematic measures of wall contact time and peak velocity. The stepwise multiple regression equation to predict 5 m RTT was: 19.6-0.75 trochanteric height-1.8 wall exit velocity-0.03 peak vertical force. Four key factors were identified from a principle components factor analysis--anthropometry and force, post-turn velocity, force preparation and rotational skills. Implications from the findings were that age-group backstrokers should 'hit the wall hard' with relatively extended legs to reduce swim distance and push-off deceleration; use minimal wall contact time, and maximise forces to develop high horizontal velocities in a streamlined position.  相似文献

The purpose of this study was to validate the calculation of reaction time (RT) and normalised power in block starts without considering arm ground reaction forces (GRFs) or using two kinematics-only methods. The RT and normalised power in the action phase were calculated using four different methods: using GRFs of arms and legs by force plates (whole F-based method), which can be regarded as the most valid method, using GRFs of legs captured by force plates (legs F-based method), using position of the centre of mass of the entire body captured by high-speed cameras (whole P-based method), and using only a partial subset of segment position (partial P-based method). Bland–Altman plots demonstrated that the RT of the legs F-based method was not similar to that of the whole F-based method: the mean difference was 7.4 ms and the 95% limits of agreement was?45.1 to 59.8 ms, and it was the least valid method for the calculation among the four methods. In contrast, the normalised power was more valid in the legs F-based method, followed by whole and partial P-based methods. This information will help researchers and practitioners to decide upon their analysis methods when analysing block start performance.  相似文献

We investigated the rotational effect of buoyant force around the body’s transverse axis, termed buoyant torque, during a 200m front crawl maximal swim. Eleven male swimmers of national or international level participated. One stroke cycle (SC) for each 50m was recorded with two above and four below water cameras. The following variables were analysed: swimming velocity; absolute and normalised buoyant force; minimum, average and maximum buoyant torque; SC and arm recovery times. The average value of buoyant torque was higher in the first 50m (14.2 ± 4.5Nm) than in the following 150m (9.3 ± 4.1Nm~10.9 ± 4.5Nm) and was directed to raise the legs and lower the head throughout the race. The change in its magnitude seemed to be linked to the shorter time spent proportionally in arm recovery (first 50m: 27.6% of SC time; next 150m: 23.3–24.4% of SC time). Most swimmers had periods of the SC where buoyant torque was directed to sink the legs, which accounted to 10% of SC time in the first 50m and about twice this duration in the next 150m. These periods were observed exclusively at some instances when the recovering arm had entered the water while the opposite arm was still underwater.  相似文献

ABSTRACT

Para Va’a is a new Paralympic sport in which athletes with trunk and/or leg impairment compete over 200 m. The purpose of this study was to examine the impact of impairment on kinematic and kinetic variables during Va’a ergometer paddling. Ten able-bodied and 44 Para Va’a athletes with impairments affecting: trunk and legs (TL), legs bilaterally (BL) or leg unilaterally (UL) participated. Differences in stroke frequency, mean paddling force, and joint angles and correlation of the joint angles with paddling force were examined. Able-bodied demonstrated significantly greater paddling force as well as knee and ankle flexion ranges of movement (ROM) on the top hand paddling side compared to TL, BL and UL. Able-bodied, BL and UL demonstrated greater paddling force and trunk flexion compared to TL, and UL demonstrated larger bottom hand paddling side knee and ankle flexion ROM compared to BL. Significant positive correlations were observed for both male and female athletes between paddling force and all trunk flexion angles and ROM in the trunk and pelvis rotation and bottom hand paddling side hip, knee and ankle flexion. The results of this study are important for creating an evidence-based classification system for Para Va’a.  相似文献

关于投掷最后用力中用力顺序的探讨   总被引:5,自引:0,他引:5  
我国投掷界对最后用力阶段的用力顺序看法比较一致,认为用力的顺序是自下而上,即腿一髋一躯干(腰、胸)一臂一手。对此,我们有不同的看法,认为正确的用力顺序是髋先发力,然后再向上向下同时发展。在髋动之初,腿的作用仅是一种被动的支撑,其主动用力应在髋动之后。不同认识的用力顺序与最后用力阶段的划分有关,单支撑和双支撑的最后用力阶段分别是不同认识的缘由。双支撑的最后用力是正确用力顺序的基础。用力顺序中的“用力”是一种人为的用力过程,而不是被动过程,是人的主动参与而不是被动接受。从而排除了腿的先动,否定了自下而上的用力顺序。在双支撑状态下的最后用力中强调髋的先动和加强髋周围肌群的力量将有助于投掷运动成绩的提高。  相似文献

Side-step cutting manoeuvres comprise the coordination between planting and non-planting legs. Increased shoe collar height is expected to influence ankle biomechanics of both legs and possibly respective cutting performance. This study examined the shoe collar height effect on kinematics and kinetics of planting and non-planting legs during an unanticipated side-step cutting. Fifteen university basketball players performed maximum-effort side-step cutting to the left 45° direction or a straight ahead run in response to a random light signal. Seven successful cutting trials were collected for each condition. Athletic performance, ground reaction force, ankle kinematics and kinetics of both legs were analysed using paired t-tests. Results indicated that high-collar shoes resulted in less ankle inversion and external rotation during initial contact for the planting leg. The high-collar shoes also exhibited a smaller ankle range of motion in the sagittal and transverse planes for both legs, respectively. However, no collar effect was found for ankle moments and performance indicators including cutting performance time, ground contact time, propulsion ground reaction forces and impulses. These findings indicated that high-collar shoes altered ankle positioning and restricted ankle joint freedom movements in both legs, while no negative effect was found for athletic cutting performance.  相似文献
