Could knee joint mechanics during the golf swing be contributing to chronic knee injuries in professional golfers?

ABSTRACT

Full three-dimensional movements and external moments in golfers’ knees and the possible involvement in injuries have not been evaluated using motion capture at high sample frequencies. This study measured joint angles and external moments around the three anatomical axes in both knees of 10 professional golfers performing golf drives whilst standing on two force plates in a motion capture laboratory. Significant differences were found in the knee joint moments between the lead and trail limbs for the peak values and throughout all stages during the swing phase. A significantly higher net abduction moment impulse was seen in the trail limb compared with the lead limb (?0.518 vs. ?0.135 Nms.kg^?1), indicating greater loading over the whole swing, which could contribute to knee lateral compartment or anterior cruciate ligament injuries. A significant correlation (r = ?0.85) between clubhead speed at ball contact and maximum joint moment was found, with the largest correlations being found for joint moments at the top of the backswing event and at the end of the follow-through. Therefore, although knee moments can contribute to high clubhead speeds, the large moments and impulses suggest that they may also contribute to chronic knee injuries or exacerbate existing conditions.  相似文献

苏联“新经济政策”终结的原因及启示——兼与李述森同志商榷     

王世涛  季开胜 《信阳师范学院学报(哲学社会科学版)》2004,24(6):116-120

列宁在国内战争胜利后,自觉地把握住了经济文化落后国家如何建设社会主义这一根本问题,努力实现了党的思维方式的伟大转变,对新经济政策问题进行了可贵的实践探索和理论探索。但由于客观历史条件的限制,他只是提出了问题,尚未完全解决问题,历史要求其后继者沿着其思路走下去。斯大林在国内战争胜利后,却未能自觉适应党所解决问题的变化,仍以处理革命问题的思维方式来处理社会主义建设问题,使其得出的理论与新经济政策的实践形成了巨大的反差,于是便终结了它。这启示我们在社会主义建设过程中,必须把握好实践、理论与其思维方式的内在关联,自觉做到实践创新和理论创新的统一。  相似文献   

An occlusion paradigm to assess the importance of the timing of the quiet eye fixation     

Samuel J. Vine  Don Hyung Lee  Rosanna Walters-Symons  Mark R. Wilson 《European Journal of Sport Science》2017,17(1):85-92

Abstract

The aim of the study was to explore the significance of the ‘timing’ of the quiet eye (QE), and the relative importance of late (online control) or early (pre-programming) visual information for accuracy. Twenty-seven skilled golfers completed a putting task using an occlusion paradigm with three conditions: early (prior to backswing), late (during putter stroke), and no (control) occlusion of vision. Performance, QE, and kinematic variables relating to the swing were measured. Results revealed that providing only early visual information (occluding late visual information) had a significant detrimental effect on performance and kinematic measures, compared to the control condition (no occlusion), despite QE durations being maintained. Conversely, providing only late visual information (occluding early visual information) was not significantly detrimental to performance or kinematics, with results similar to those in the control condition. These findings imply that the visual information extracted during movement execution – the late proportion of the QE – is critical when golf putting. The results challenge the predominant view that the QE serves only a pre-programming function. We propose that the different proportions of the QE (before and during movement) may serve different functions in supporting accuracy in golf putting.  相似文献

儒家伦常法则:忠恕之道新解   总被引：1，自引：0，他引：1  

刘美红  周远成 《衡阳师范学院学报》2011,32(4):47-51

忠恕之道作为儒家处理自我与他人关系的伦常准则,包括如何对待自己和如何对待他人两个相互贯通、不可分割的层面。"忠"侧重如何对待自己,它实际由"中"派生出来,强调的是通过"执中"、"正己"而"尽己成性",与三代以来的尚"中"精神一脉相承。"恕"着重如何对待别人,它强调通过推己及人、以成全他人,有"己欲立而立人,己欲达而达人"、"己所不欲,勿施于人"等两种表述形式。依儒家之见,"忠恕违道不远",只有既正确对待自己,又正确对待别人,我们才能达到"在邦无怨,在家无怨"的人生境界。  相似文献   

学术思潮与清初骈文的新气象     

张明强 《广西师范大学学报(哲学社会科学版)》2015,(3):86-91

明末清初,因战乱频仍,政权更迭,士人的危机感顿然加剧,社会上逐渐形成以经世致用和博古通今为主的学术思潮,这两种思想深刻影响着清初骈文的内容和风格。受经世致用思想的影响,清初骈文家如陈维崧、吴绮、陆繁弨等皆关注现实,抒发真情实感,故清初骈文具有时代感和重情意识;而崇尚“博通”的学术追求,反映在骈文创作上表现为追求富丽典赡之美。清初骈文内容的充实和提高有力地推动了清初骈文的复兴,为清代中叶骈文全盛开拓了路径。  相似文献
