一、"标枪肘"产生的生理原因错误的"撇枪"动作导致肘关节损伤,一些运动员肩关节韧带柔韧性较差,最后用力阶段无法完成翻肩动作,肘关节低于肩关节,导致肩外投枪。另一种情况是肩膀领先于肘关节发力,造成"撇枪"。还有,准备活动不充分,部分运动员不重视准备活动,专项准备活动不足,无法使骨骼肌和韧带温度升高,不能适应投掷标枪时对关节的要求。 相似文献

原地推铅球是高考体育专业的必考科目,技术含量较高。在多年的训练中,经常发现学生在原地推铅球时,投掷臂肘关节的位置在技术方面存在错误,也就是说投掷臂肘关节易下降,主要原因是该项目动作技术比较复杂。学生对动作技术理解和掌握较难,如果不及时准确地纠正学生在训练中的错误动作,就会形成错误的动力定型,影响推铅球的训练质量。 相似文献

一、损伤原因和原理 肘关节损伤一般常发生在标枪出手的最后用力阶段,此时标枪的反作用力迫使前臂突然外展,旋后(被动损伤)或在投掷时屈手肌群和旋前圆肌猛烈收缩(主动损伤),从而造成肘关节的损伤。当伤者做屈肘、屈腕动作时感到疼痛,同时稍加外力让伤者做前臂旋前动作时备感疼痛,这表明其主要是屈手肌群或旋前圆肌起始部的损伤。而当医者一手托伤者肘部,另一手稍外展其前臂,伤者感到疼痛,这说明主要是肘关节的尺侧副韧带损伤。 相似文献

通过分析青年男子举重运动员肘关节屈伸肌群的力量参数，探讨肘关节屈伸肌群在举重专项训练中的作用，为预防肘关节损伤及科学训练提供理论依据。采用Cybex—Norm型等速测力与康复系统，在预定角速度90°／s．180°／s和300°／s下对上海举重队9名青年男子举重运动员肘关节进行等速向心屈伸肌力测试。结果发现举重运动员肘关节屈伸肌群相对峰力矩、相对总劝和相对平均功率随着运动速度的增大而减小，屈伸肌群峰力矩比值接近1．0。表明举重项目中肘关节屈伸肌群主要功能是维持运动中关节的稳定性，而两侧肘关节同名肌群肌力素质的不均衡性可能是阻碍专项能力韦黾高的重要因素和诱发运动性伤病的潜在因素。 相似文献

Tennis coaches often use the fundamental throwing skill as a training tool to develop the service action. However, recent skill acquisition literature questions the efficacy of non-specific training drills for developing complex sporting movements. Thus, this study examined the mechanical analogy of the throw and the tennis serve at three different levels of development. A 500 Hz, 22-camera VICON MX motion capture system recorded 28 elite female tennis players (prepubescent (n = 10), pubescent (n = 10), adult (n = 8)) as they performed flat serves and overhand throws. Two-way ANOVAs with repeated measures and partial correlations (controlling for group) assessed the strength and nature of the mechanical associations between the tasks. Preparatory mechanics were similar between the two tasks, while during propulsion, peak trunk twist and elbow extension velocities were significantly higher in the throw, yet the peak shoulder internal rotation and wrist flexion angular velocities were significantly greater in the serve. Furthermore, all of these peak angular velocities occurred significantly earlier in the serve. Ultimately, although the throw may help to prime transverse trunk kinematics in the serve, mechanics in the two skills appear less similar than many coaches seem to believe. Practitioners should, therefore, be aware that the throw appears less useful for priming the specific arm kinematics and temporal phasing that typifies the tennis serve. 相似文献

The importance of proximal-to-distal sequencing in human performance throwing has been reported previously. However, a comprehensive comparison of the proximal-to-distal sequence in team-handball throwing in athletes with different training experience and competition is lacking. Therefore, the aim of the study was to compare the ball velocity and proximal-to-distal sequence in the team-handball standing throw with run-up of players of different skill (less experienced, experienced, and elite). Twenty-four male team-handball players (n = 8 for each group) performed five standing throws with run-up with maximal ball velocity and accuracy. Kinematics and ball trajectories were recorded with a Vicon motion capture system and joint movements were calculated. A specific proximal-to-distal sequence, where elbow flexion occurred before shoulder internal rotation, was found in all three groups. These results are in line with previous studies in team-handball. Furthermore, the results of the present study suggest that in the team-handball standing throw with run-up, increased playing experience is associated with an increase in ball velocity as well as a delayed start to trunk flexion. 相似文献

Cricket bowling is traditionally thought to be a rigid-arm motion, allowing no elbow straightening during the delivery phase. Conversely, research has shown that a perfectly rigid arm through delivery is practically unattainable, which has led to rule changes over the past years. The current rule requires a bowler not to increase the elbow angle by more than 15 degrees, thus requiring a measurement to confirm legality in "suspect" bowlers. The aims of this study were to evaluate whether the current rule is maintained over a range of bowlers and bowling styles, and to ascertain whether other kinematics measures may better differentiate between legal and suspect bowling actions. Eighty-three bowlers of varying pace were analysed using reflective markers and a high-speed (240 Hz) eight-camera motion analysis system in a laboratory. The change in elbow segment angle (minimum angle between the arm and forearm), the change in elbow extension angle with respect to the flexion-extension axis of a joint coordinate system, and the elbow extension angular velocity at ball release were measured. We found that bowlers generally bowled within a change in elbow extension angle of 15.5 degrees. However, this limit was unable to differentiate groups of bowlers from those who were suspected of throwing in the past. Improved differentiation was attained using the elbow extension angular velocity at ball release. The elbow extension angular velocity at ball release may be conceptually more valid than the elbow extension angle in determining which bowlers use the velocity-contributing mechanisms of a throw. Also, a high value of elbow extension angular velocity at ball release may be related to the visual impression of throwing. Therefore, it is recommended that researchers and cricket legislators examine the feasibility of specifying a limit to the elbow extension angular velocity at ball release to determine bowling legality. 相似文献
