田径表演赛可行性探析     

崔永衡 《体育科技文献通报》2015,(1)

随着科技水平的发展，电视、多媒体网络等各种传播媒介的迅速发展，体育产业的迅速崛起，人们生活质量的提高、财富的积累，使得人们对体育的诉求也在不断的发生着变化。各种体育赛事逐步融入了表演赛，来扩大本项运动的国际影响力。由于体育明星效应，使得一些体育运动在国内一度掀起过高潮。那么，我们可以借鉴这种市场化的操作方式，从宏观的角度论述田径表演赛，通过明星效应，结合市场管理的方法，提升对田径运动兴趣，加大对田径运动知识的了解、认识，从而起到缓解瓶颈期学校体育中田径常年不受学生青睐的尴尬局面，迎来田径发展新“春天”。  相似文献

Exploring the effects of substituting basketball players in high-level teams     

Miguel-Ángel Gómez  Roberto Silva  Alberto Lorenzo  Rasa Kreivyte  Jaime Sampaio 《Journal of sports sciences》2017,35(3):247-254

Substituting basketball players during competition is a key process to optimise collective performance. Available research on this topic is scarce, probably due to the difficulty in isolating these effects; thus, the aim of this study was to identify the temporal effects of substitutions in basketball (Spanish professional basketball league). The sample was composed of 1118 substitutions gathered from 21 basketball games. The analysed variables were coach-controlled (player and team’s personal fouls, player in and player out roles, player’s in and out minutes on-court and timeout situation); on-court (foul committed, free throws, 2- and 3-point field-goal effectiveness) and situational variables (scoreline, quality of opposition, game location and game quarter). The results showed positive scoring performances after the substitution for all the analyses. During the first quarter, there were significant effects for fouls committed, scoreline and game location after the substitution. The player’s out personal fouls, free-throw effectiveness, player in, minutes on-court player in, timeout situation and 3-point field-goal effectiveness were significant during the second quarter. The team’s personal fouls, game location, and scoreline were identified as important in the third quarter. The fourth quarter did not show significant effects on the independent variables. Current findings allow optimising coaches’ plans and team management of on-court and bench players throughout the game.  相似文献   

Identification of temporal factors related to shot performance for indoor recurve archery     

Andrew J. Callaway  Johanna Wiedlack  Mario Heller 《Journal of sports sciences》2017,35(12):1142-1147

The purpose of this study was to investigate the temporal phases of the archery shot cycle that distinguish the arrows distance from centre, in an attempt to understand critical factors that affect performance. Fifteen archers of varying ability each performed 30 shots at 18 m. Fourteen potential predictor variables were measured for statistical modelling by stepwise multiple linear regression. The results show that pre-shot time (pre-performance routine), follow-through time (post-performance routine), aiming time, speed of the arrow and the %variation in clicker-release time, account for 7.7% of the variation in predicting shot performance. The results have implications for practice demonstrating factors that coaches should focus on to develop their athletes. Further work on pre-, but more importantly, post-performance routines are needed generally within sport research as they are lacking and have been shown to be important contributing factors in a number of sports.  相似文献   

The use of player physical and technical skill match activity profiles to predict position in the Australian Football League draft     

Carl T. Woods  James P. Veale  Neil Collier  Sam Robertson 《Journal of sports sciences》2017,35(4):325-330

This study investigated the extent to which position in the Australian Football League (AFL) national draft is associated with individual game performance metrics. Physical/technical skill performance metrics were collated from all participants in the 2014 national under 18 (U18) championships (18 games) drafted into the AFL (n = 65; 17.8 ± 0.5 y); 232 observations. Players were subdivided into draft position (ranked 1–65) and then draft round (1–4). Here, earlier draft selection (i.e., closer to 1) reflects a more desirable player. Microtechnology and a commercial provider facilitated the quantification of individual game performance metrics (n = 16). Linear mixed models were fitted to data, modelling the extent to which draft position was associated with these metrics. Draft position in the first/second round was negatively associated with “contested possessions” and “contested marks”, respectively. Physical performance metrics were positively associated with draft position in these rounds. Correlations weakened for the third/fourth rounds. Contested possessions/marks were associated with an earlier draft selection. Physical performance metrics were associated with a later draft selection. Recruiters change the type of U18 player they draft as the selection pool reduces. juniors with contested skill appear prioritised.  相似文献   

高校人才集聚绩效评价方法探析:集聚指数的编制与应用   总被引：1，自引：0，他引：1  

田凌晖 《教师教育研究》2007,19(2):45-49

优秀人才的集聚是高校核心竞争力提升的首要前提,而如何考量高校人才集聚的绩效成为亟待解决的难题。本研究运用统计指数相关方法编制了高校人才集聚指数作为绩效评价的一种方法,并进一步选择位于东北、西北、中部、东部和东南的5所“985”高校,对其2000年以来人才集聚指数进行测算,通过分析测算结果发现五所高校的人才流动均呈逐步优化的发展态势,且发展态势相对稳健,但高校间人才集聚绩效存在一定差异,而差异幅度在一段时间内表现得相对稳定。  相似文献

The analysis and forecasting of male cycling time trial records established within England and Wales     

Bryce Dyer  Hossein Hassani  Mehran Shadi 《Journal of sports sciences》2016,34(13):1222-1230

The format of cycling time trials in England, Wales and Northern Ireland, involves riders competing individually over several fixed race distances of 10–100 miles in length and using time constrained formats of 12 and 24 h in duration. Drawing on data provided by the national governing body that covers the regions of England and Wales, an analysis of six male competition record progressions was undertaken to illustrate its progression. Future forecasts are then projected through use of the Singular Spectrum Analysis technique. This method has not been applied to sport-based time series data before. All six records have seen a progressive improvement and are non-linear in nature. Five records saw their highest level of record change during the 1950–1969 period. Whilst new record frequency generally has reduced since this period, the magnitude of performance improvement has generally increased. The Singular Spectrum Analysis technique successfully provided forecasted projections in the short to medium term with a high level of fit to the time series data.  相似文献
