Effect of gender on trunk and pelvis control during lateral movements with perturbed landing     

Elmar Weltin  Albert Gollhofer  Guillaume Mornieux 《European Journal of Sport Science》2016,16(2):182-189

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   

校本课程评价研究综述     

课题组 《天中学刊》2006,21(6):12-15

我国的校本课程评价研究存在着对实践问题关注不够、独创性不高、研究不够深入以及忽略不同类型校本课程之间的区别等问题。为此,需要采取课程研究模式向课程实践转变、课程评价理论由引进向转化和创生转变、研究中坚持全面、整合的课程价值观等相应之策略。  相似文献   

小学数学课堂练习设计的策略     

王小喜 《宁波教育学院学报》2008,10(1):121-123

在小学数学教学中,练习课约占总教时的一半多,几乎没有一节课是只讲不练的。古人云:"拳不离手,曲不离口"。可见练习的重要性,如何探索新课程理念下的课堂练习设计,是广大教师共同关注的课题。教师可根据教学内容,紧扣教学目标,设计有"坡度"、"难度"、"密度"的练习,加大知识"跨度,"变换练习角度,提高练习设计的有效性。  相似文献

英语双关语的翻译     

王志伟 《重庆师专学报》2006,5(5):103-106

双关语是最难翻译的修辞现象之一，英语双关语的翻译策略通常有以下几种。对等翻译法将双关语译为相同的双关语，主要适用于建立在人类共同认知基础上的双关语和部分结构双关语；变通对等法是通过创造双关语译为不同的双关语，主要适用于思想主题意义不大严肃的文字游戏类双关语。体现不同文化特色和语言特点的双关语有时也可以通过语音、语义或形式手段译为类双关语，还可以通过释义、加注等方法进行补偿。双关语的翻译还包括谐音法、省略法、移植法等。  相似文献

A Comparative Study of Two Chinese Versions of Animal Farm     

杨梅CHENG  Jing 《海外英语》2016,(15):158-159

Animal Farm succeeds in establishing George Orwell's position as a master in literature with its profound moral and hidden but killing sarcasms.And it has been translated into many languages around the world,arousing heated response.So far,there are seventeen versions in China.However,the academic studies focus on the significance of its literary value and political aspects,paying little attention to the systemic study of its translations.The thesis chooses the versions of Rong Rude and Fu Weici and compares them from lexical,syntactical and discourse aspects.Through the comparative study,the author finds out that the two translators apply different translation strategies.Rong tends to adopt foreignization strategy,while Fu is inclined to apply domestication strategy.  相似文献
