秋千,在古代本是北方民族的狩猎、采集等生产劳动之外的一种嬉戏活动。“北方山戎之戏,以习轻轿者。”（《古今艺术图》）春秋时期传入中原,而且延续了两千多年,经久不衰。汉武帝时,秋千在宫廷得到发展。唐代人高天际在《汉武帝后庭秋千赋·序》中载“秋千者,千秋也... 相似文献

有一种悬挂在轿车领域的普及率非常高。高到什么程度？绝大多数的A级车以及几乎所有的A级以下车型都采用这种悬挂,部分B级车也有采用这种设计的。你先想到什么？麦弗逊？的确,麦弗逊是普及率最高的悬挂,不过我们这回说的不是麦弗逊,而是纵臂扭转梁。这种悬挂的普及率快赶上麦弗逊了,但我们对其却依然陌生。为什么？因为SUV上极少采用。那么纵臂扭转梁悬挂有何玄妙之处,让它在轿车领域如此普及,而又在SUV领域如此稀少呢？ 相似文献

Groin pain is a common cause of athletic disability and often involves the adductor longus. A common complaint of patients with groin problems is pain while preparing to kick the ball. The purpose of this study was to examine muscle length and activation of the adductor longus while kicking a soccer ball. Three-dimensional joint positions and muscle activation were obtained from 15 National Collegiate Athletic Association (NCAA) Division 1 male soccer players during maximal effort kicks. Musculoskeletal modeling techniques incorporating joint position and muscle attachments were used to estimate adductor longus length from the beginning of the kicking leg's swing phase until ball strike. The maximum rate of stretch of the adductor longus (22.3 ± 5.3 cm/s) and maximum hip extension (23.3 ± 8.8°) occurred near 40% of swing phase. Activation of the adductor longus occurred between 10% and 50% of the swing phase. Adductor longus maximum length occurred at 65% of the swing phase. Maximum hip abduction (25.3 ± 5.4°) occurred at 80% of swing phase. The adductor longus appears to be at risk of strain injury during its transition from hip extension to hip flexion. This knowledge could be applied to muscle injury prevention and rehabilitation programs to aid with treatment of adductor longus related groin pain. 相似文献

Many field sports involve equipment that restricts one or both arms from moving while running. Arm swing during running has been examined from a biomechanical and physiologic perspective but not from an injury perspective. Moreover, only bilateral arm swing suppression has been studied with respect to running. The purpose of this study was to determine the influence of running with one arm restrained on lower extremity mechanics associated with running or sport-related injury. Fifteen healthy participants ran at a self-selected speed with typical arm swing, with one arm restrained and with both arms restrained. Lower extremity kinematics and spatiotemporal measures were analysed for all arm swing conditions. Running with one arm restrained resulted in increased frontal plane knee and hip angles, decreased foot strike angle, and decreased centre of mass vertical displacement compared to typical arm swing or bilateral arm swing restriction. Stride length was decreased and step frequency increased when running with one or both arms restrained. Unilateral arm swing restriction induces changes in lower extremity kinematics that are not similar to running with bilateral arm swing restriction or typical arm swing motion. Running with one arm restrained increases frontal plane mechanics associated with risk of knee injury. 相似文献

The aim of this study was to quantify clearance mechanics during gait. Seventeen children diagnosed with hemiplegic cerebral palsy underwent a three-dimensional gait analysis evaluation. Dynamic leg lengths were measured from the hip joint center to the heel, to the ankle joint center and to the forefoot throughout the gait cycle. Significant asymmetry was observed during stance, initial and terminal swing phases, where the hemiplegic limb was found shorter by using a paired t-test at 51 sample points (p < .05). The hemiplegic side was restricted in achieving maximal length during terminal swing. The ratio between the maximal dynamic leg length during the stance phase to minimal dynamic leg length during the swing phase was found higher on the non-involved side and lower on the hemiplegic side (p < .05). Quantifying clearance mechanics based on dynamic leg length can provide an additional insight into the analysis of gait patterns and might assist in detecting time of abnormal kinematic deviations. 相似文献

The purpose of this study was to investigate the time series relationships between the peak musculotendon length and electromyography (EMG) activation during overground sprinting to clarify the risk of muscle strain injury incidence in each hamstring muscle. Full-body kinematics and EMG of the right biceps femoris long head (BFlh) and semitendinosus (ST) muscles were recorded in 13 male sprinters during overground sprinting at maximum effort. The hamstring musculotendon lengths during sprinting were computed using a three-dimensional musculoskeletal model. The time of the peak musculotendon length, in terms of the percentage of the running gait cycle, was measured and compared with that of the peak EMG activity. The maximum length of the hamstring muscles was noted during the late swing phase of sprinting. The peak musculotendon length was synchronous with the peak EMG activation in the BFlh muscle, while the time of peak musculotendon length in the ST muscle occurred significantly later than the peak level of EMG activation (p < 0.05). These results suggest that the BFlh muscle is exposed to an instantaneous high tensile force during the late swing phase of sprinting, indicating a higher risk for muscle strain injury. 相似文献

踢球是决定比赛胜负的主要技术手段之一.其中,脚背内侧踢球、正脚背踢球、脚内侧踢球及脚背外侧踢球是4种最基本的踢球方法.4种踢球方法踢球腿的摆动具有相似性,运动生物力学手段对其进行研究比较发现,脚背内踢球摆动腿的大腿前摆角最大,脚内侧踢球小腿前摆角最小,脚触球时,正脚背踢球与脚背外侧踢球的小腿角速度最快,脚内侧最慢.摆动腿的摆动存在鞭打动作,但不仅仅局限于鞭打动作. 相似文献

采用文献研究及生物力学分析等方法,对我国男子竞走运动员的技术进行分析,发现在1996年前的竞走规则和定义的影响下,我国男选手逐步形成了小步幅、快频率的技术特征。生物力学分析表明,髋的水平速度与摆动时间里高度相关,适当增加髋关节围绕身体垂直轴转动的速度,对提高步长有积极效果。控制足触地的角度和加强前摆着地技术的训练应引起重视。 相似文献
