篮球技战术的理论思维与突破   总被引：2，自引：0，他引：2  

王新华 《广州体育学院学报》1996,(3)

我国篮球技战术的理论思维始终是一个薄弱环节,落后于运动实践的发展。我们的理论视点偏重于孤立静止地认识技术,欧美强队却以“时空对抗技术”走在技术发展的前列。我们的战术思维仍沿袭着“固定化、模式化”的老路。世界强队的“机动进攻”的战术打法更趋向于机动灵活。差距是明显的。我们应学会科学的理论思维,来探索篮球技战术发展的规律,形成正确的认识,完成对运动实践的指导作用。  相似文献

The expected value of possession in professional rugby league match-play     

Thomas Kempton  Nicholas Kennedy  Aaron J. Coutts 《Journal of sports sciences》2016,34(7):645-650

This study estimated the expected point value for starting possessions in different field locations during rugby league match-play and calculated the mean expected points for each subsequent play during the possession. It also examined the origin of tries scored according to the method of gaining possession. Play-by-play data were taken from all 768 regular-season National Rugby League (NRL) matches during 2010–2013. A probabilistic model estimated the expected point outcome based on the net difference in points scored by a team in possession in a given situation. An iterative method was used to approximate the value of each situation based on actual scoring outcomes. Possessions commencing close to the opposition’s goal-line had the highest expected point equity, which decreased as the location of the possession moved towards the team’s own goal-line. Possessions following an opposition error, penalty or goal-line dropout had the highest likelihood of a try being scored on the set subsequent to their occurrence. In contrast, possessions that follow an opposition completed set or a restart were least likely to result in a try. The expected point values framework from our model has applications for informing playing strategy and assessing individual and team performance in professional rugby league.  相似文献   

Perceptual-cognitive expertise of handball coaches in their young and middle adult years     

Lennart Fischer  Joseph Baker  Rebecca Rienhoff  Bernd Strauß  Judith Tirp  Dirk Büsch 《Journal of sports sciences》2016,34(17):1637-1642

There is little research investigating the maintenance of perceptual-cognitive expertise in general and even less comparing coaches of different ages. The aim of this study was to test for perceptual-cognitive differences between age groups, licence levels, and their interaction. This study investigated differences in skilled performance between young and middle-aged coaches of three different skill levels. Participants performed an accuracy-oriented pattern recall (mean distance in pixel) and a time-oriented flicker test (mean detection time in ms). There were some significant differences between age groups and between skill groups for both tests, but no interactions. For the pattern recall test, the effect sizes were larger for skill level differences, while for the flicker test effects were larger for ageing. These results suggest coaches are able to maintain accuracy skills better than reaction timed tasks. This is in line with findings on speeded performance in general populations, which show declines with age. Moreover, results also support findings on perceptual expertise in skills where accuracy was important.  相似文献
