加拿大高校办学模式对我们的启示     

付永昌 《南阳师范学院学报》2005,4(11):102-104

加拿大的大学都是公立大学，没有类似于英国或美国的私立大学。加拿大高校的办学模式及在办学过程中所表现出的特点，比西方其他发达国家的大学对我国高等教育的改革与发展更具启示性。  相似文献

Muscle activity and spine load during anterior chain whole body linkage exercises: the body saw,hanging leg raise and walkout from a push-up     

Stuart McGill  Jordan Andersen  Jordan Cannon 《Journal of sports sciences》2015,33(4):419-426

This study examined anterior chain whole body linkage exercises, namely the body saw, hanging leg raise and walkout from a push-up. Investigation of these exercises focused on which particular muscles were challenged and the magnitude of the resulting spine load. Fourteen males performed the exercises while muscle activity, external force and 3D body segment motion were recorded. A sophisticated and anatomically detailed 3D model used muscle activity and body segment kinematics to estimate muscle force, and thus sensitivity to each individual's choice of motor control for each task. Gradations of muscle activity and spine load characteristics were observed across tasks. On average, the hanging straight leg raise created approximately 3000 N of spine compression while the body saw created less than 2500 N. The hanging straight leg raise created the highest challenge to the abdominal wall (>130% MVC in rectus abdominis, 88% MVC in external oblique). The body saw resulted in almost 140% MVC activation of the serratus anterior. All other exercises produced substantial abdominal challenge, although the body saw did so in the most spine conserving way. These findings, along with consideration of an individual's injury history, training goals and current fitness level, should assist in exercise choice and programme design.  相似文献

Time to embrace the complexity when analysing GPS data? A systematic review of contextual factors on match running in rugby league     

Nicholas Dalton-Barron  Sarah Whitehead  Gregory Roe  Cloe Cummins  Clive Beggs  Ben Jones 《Journal of sports sciences》2020,38(10):1161-1180

ABSTRACT

This systematic review aimed to identify and summarise associations between currently identified contextual factors and match running in senior male professional rugby league. Eligible articles included at least one contextual factor and used GPS to measure at least one displacement variable within competitive senior, male, professional rugby league matches. Of the 15 included studies, the identified contextual factors were grouped into factors related to individual characteristics (n = 3), match result (n = 4), team strength (n = 2), opposition strength (n = 3), match conditions (n = 6), technical and tactical demands (n = 6), spatial and temporal characteristics (n = 7), and nutrition (n = 1). Speed was the most commonly reported measure of match running (100%), followed by distance (47%), and acceleration (20%). Inconsistencies were found between studies for most contextual factors on match running. Higher speeds were generally associated with higher fitness, encountered earlier in the match and whilst defending. All 15 studies utilised a univariate approach to quantify associations of a contextual factor. The inconsistencies found in the associations of given contextual factors highlight the complex and multi-faceted nature of match running. Therefore, practitioners should consider contextual factors when analysing and interpreting GPS data.  相似文献
