武术训练中膝关节损伤的防治 总被引：1，自引：0，他引：1
膝关节损伤常见于武术训练以及武术课的教学过程中。由于武术以弓步、马步、仆步、虚步、歇步为主要步型,各步型均要求身体处于半蹲姿势,关节稳定性相对下降,最易受伤。武术的跳跃动作较多,要求起得高、落得稳,且跳跃动作的起跳、落地技术多变,需要膝部的迅猛发力。落地时技术也多用屈膝半蹲的姿势定型,或起跳腿单足落地,或屈膝盘膝落地技术。因此腾空高而落地猛,往往易使膝部受伤。 相似文献

竞技武术套路高难度动作完成质量是决定比赛胜负的关键因素,而高难度动作落地稳定性是完成高难度动作的关键环节,提高女子运动高难度动作落地稳定性,避免扣分点,是当前竞技武术套路女子运动员急需解决的技术问题.应用摄像分析等手段,对北京奥运会女子南拳金牌获得者林凡等35名运动员的难度动作进行运动生物力学诊断,寻找落地不稳定因素.研究结果表明:女子运动员在完成高难度动作中腾空时间明显不足,空中旋转角度不够,增加了落地稳定性的难度;不同的落地姿势有不同的重心高度、落地缓冲距离、落地支撑面积;并根据运动员个体的特点,提出个体的理想技术模式,模拟比赛负荷强度训练难度动作,在为备战北京奥运会和第十一届全运会的训练中,提供了科技服务,保障了被跟踪科研服务的运动员在这两次大赛中获得了金牌. 相似文献

武术是中华民族的文化遗产。武术套路是武术的主要运动形式,而腾空飞脚是武术跳跃动作中最基本的动作,尤其在长拳和长拳类器械套路中经常出现。所以,腾空飞脚动作分析的研究,对教学、训练和比赛都有重要意义。1 腾空飞脚技术动作结构的阶段划分腾空飞脚有原地起跳和助跑起跳之分,而后者又有一步、二步和击步之分。由于上步和击步腾空飞脚运用比较普遍,动作也比较复杂,本文以上步腾空飞脚(右脚起跳,左脚先落地)为例,划分上步、起跳、腾空和落地等四阶段。 相似文献

优秀武术套路运动员膝关节损伤调查分析 总被引：1，自引：0，他引：1
膝关节损伤是长期困扰武术套路运动员可持续发展的问题之一.为了解目前我国优秀武术套路运动员膝关节损伤的现状及原因,通过问卷调查法对国家队优秀武术套路运动员进行调查.结果表明,优秀武术套路运动员膝关节损伤现象较为严重,且存在普遍性问题.造成膝关节损伤的主要原因一是,长期繁重的训练任务造成运动员膝关节疲劳,集中表现在C级(高级别)难度动作加连接动作的训练中.具体表现为跳跃动作起跳至落地过程中,运动员不正确的身体姿势和动作要领;腾空落地瞬间,运动员膝关节承受过重压力而未正确使用落地缓冲;腾空落地时由于旋转度数不足所造成的生硬连接.二是,难度动作训练之前的准备活动不充分以及训练时缺少必要的保护措施.因此,加强膝关节肌肉力量训练和难度动作完成前的准备活动,教练员对运动员完成难度动作采取有效合理的保护措施,是预防武术套路运动员膝关节损伤的重要手段. 相似文献

AbstractLateral movements like cutting are essential in many team sport disciplines. The aim of the present study was to analyse adaptations in motor control in response to task unpredictability during lateral movement execution. Twelve subjects performed lateral jumps with different landing modalities (stable, sliding or counteracting) that were either known (predictable setting) or unknown (unpredictable setting) prior to movement execution. Results revealed that regardless of the landing modality, hip joint abduction was significantly greater in the unpredictable compared to predictable setting. Furthermore, during the sliding landing modality, hip flexion decreased from 211 ± 7° to 207 ± 7° and knee flexion decreased from 26 ± 4° to 24 ± 4° at the instant of ground contact in the unpredictable compared to predictable condition. During the stable landing modality, the knee joint abduction increased from ?0.3 ± 6° to ?3 ± 6° after initial ground contact in the unpredictable compared to predictable setting. The present results support our hypothesis that pre-programmed motor activity depends on the predictability of the landing modality during lateral movements. According to its adaptation in the frontal plane and in some extent in the sagittal plane, the hip joint seems to play the major role in the modulation of the pre-programmed activity for successful lateral jump execution in an unpredictable setting. However, these kinematic adaptations are concerning since these changes were associated with higher knee abduction during the stable landing modality and therefore with possible higher risk of injury. 相似文献

In lateral reactive movements, core stability may influence knee and hip joint kinematics and kinetics. Insufficient core stabilisation is discussed as a major risk factor for anterior cruciate ligament (ACL) injuries. Due to the higher probability of ACL injuries in women, this study concentrates on how gender influences trunk, pelvis and leg kinematics during lateral reactive jumps (LRJs). Perturbations were investigated in 12 men and 12 women performing LRJs under three different landing conditions: a movable landing platform was programmed to slide, resist or counteract upon landing. Potential group effects on three-dimensional trunk, pelvic, hip and knee kinematics were analysed for initial contact (IC) and the time of peak pelvic medial tilt (PPT). Regardless of landing conditions, the joint excursions in the entire lower limb joints were gender-specific. Women exhibited higher trunk left axial rotation at PPT (women: 4.0 ± 7.5°, men: ?3.1 ± 8.2°; p = 0.011) and higher hip external rotation at both IC and PPT (p < 0.01). But women demonstrated higher knee abduction compared to men. Men demonstrated more medial pelvic tilt at IC and especially PPT (men: –5.8 ± 4.9°, women: 0.3 ± 6.3°; p = 0.015). Strategies for maintaining trunk, pelvis and lower limb alignment during lateral reactive movements were gender-specific; the trunk and hip rotations displayed by the women were associated with the higher knee abduction amplitudes and therefore might reflect a movement strategy which is associated with higher injury risk. However, training interventions are needed to fully understand how gender-specific core stability strategies are related to performance and knee injury. 相似文献

AbstractThis study aimed to elucidate the movements requiring greater trunk accelerations and its frequencies during badminton games, and compare the acceleration components among such movements. Trunk acceleration was measured using a triaxial accelerometer during badminton games. The moments that generated >4 G resultant acceleration were extracted, and movements consistent with the extracted moments were identified. We calculated the extracted movement ratio and frequency and compared the resultant, mediolateral, vertical and anteroposterior accelerations between the top five extracted movements. There were 1,342 movements that generated >4 G [mean, 7.72 (95% confidence interval, 7.31–8.14) cases/min]. The top five movements were lunging during underhand strokes with the dominant hand side leg, landing after overhand strokes on the dominant and non-dominant hand side leg, and cutting from a split step using the dominant and non-dominant hand side leg. Landing on the dominant hand side leg had a greater resultant acceleration than the other movements and had the greatest impact during the badminton game. Lunging during underhand strokes on the dominant hand side leg had greater mediolateral acceleration than the other movements. These results reflected the properties of badminton. 相似文献
