Individual and contextual factors in ethical decision making: A case study of the most significant doping scandal in Canadian university sports history     

《Sport Management Review》2016,19(1):61-68

This case study is written for instructors of sport management courses focused on ethics and integrity-related issues in team environments. The case highlights the real world example of the University of Waterloo Warriors varsity football that, in 2010, experienced the most significant doping scandal in Canadian university sports history, with a total of nine anti-doping rule violations asserted through the Canadian Centre for Ethics in Sport. This case study also incorporates the findings of an independent review of the Waterloo football program in relation to the use of banned substances, and includes first-hand accounts from Bob Copeland who was the acting director of athletics. These findings are then interpreted in the context of relevant theory related to performance enhancing drugs (PEDs) use. Along with the findings of this review, which included interviews with athletes, coaches, and administrators, the case study provides important insights into ethical decision making processes and leadership structures in a team sport environment. Particular emphasis is placed on the role that individual cognitive antecedents and contextual organizational factors (i.e., policies, leadership, ethical climate, and infrastructure) play in ethical decision-making processes.  相似文献   

The effects of static stretching on speed and agility: One or multiple repetition protocols?     

Alexandra Avloniti  Ioannis G. Fatouros  Maria Protopapa  Ioannis Athanailidis  Christina Avloniti 《European Journal of Sport Science》2016,16(4):402-408

Although static stretching (SS) is utilized during warm-up before training and competition, the results about its effects on performance remain controversial. We examined whether performing a stretch of short-to-moderate duration (<60 sec) in a single repetition produces a similar or different effect on speed and agility performance from the effect which is produced while performing the same stretch in multiple repetitions of the same total duration. According to a repeated measurement design, 40 trained males were randomly assigned to either (1) a single repetition group or (2) a multiple repetition group. The participants in each group performed five trials: a control trial (no stretches were performed) and four experimental trials of SS protocols consisting of five exercises performed at either 20 sec (2 × 10 in the second group), 30 sec (3 × 10 in the second group), 40 sec (4 × 10 in the second group) or 60 sec (6 × 10 in the second group) of total duration. A two-way repeated measures analysis of variance showed that the participants in both group improved their speed performance in response to the 20-sec trial, whereas agility remained unaffected. Data analysis also revealed that the repetition number did not affect speed and agility performance. These data suggest that SS of short duration (<30 sec) may actually improve acute speed performance, whereas SS of moderate duration may not hamper speed and agility performance. Moreover, the effects of SS protocols are related to the total duration of each exercise and not to the number of repetitions in which each exercise is performed.  相似文献   

A topography of free kicks in soccer     

Daniel Link  Otto Kolbinger  Hendrik Weber  Michael Stöckl 《Journal of sports sciences》2016,34(24):2312-2320

ABSTRACT

This study investigates the spatial relationship of performance variables for soccer free kicks. In order to suggest ways in which players might optimise their performance, we collected data from free kicks (<35 m to goal line) of two German Bundesliga seasons (2013/14, 2014/15) (n = 1624). In the analysis, we applied the ISO-map approach using colour gradients to visualise the mean values of a variable on a 2D-map of the pitch. Additionally, variograms were used to describe the degree of spatial dependence of the free kick variables. Results show that DENSITY, TYPE OF PLAY, PLAYERS IN WALL, DISTANCE TO WALL and RULE VIOLATION were strongly spatially dependent. Centrality and proximity to the goal increased the variables PLAYERS IN WALL, RULE VIOLATIONS and INTERRUPTION TIME, and the ratio of goals scored increased from 5.9% (central far) to 10.9% (central near). In 70.9% of the shots, players preferred a switched laterality, which did not result in a higher success rate. Furthermore, there was no statistical advantage for the defensive team when DISTANCE TO WALL was below 9.15 m or when there was a RULE VIOLATION. Crosses had a success rate (i.e., first controlled ball contact after the cross) of 20.8%. Played with natural laterality, they were 5% more successful than with switched laterality. Crosses from the right side outside the penalty box were 10% more successful than from the left side. Therefore, it might be worthwhile practising the defence of balls coming from this side.  相似文献   

Multivariate analyses of individual variation in soccer skill as a tool for talent identification and development: utilising evolutionary theory in sports science     

Robbie S. Wilson  Rob S. James  Gwendolyn David  Ecki Hermann  Oliver J. Morgan  Amanda C. Niehaus 《Journal of sports sciences》2016,34(21):2074-2086

The development of a comprehensive protocol for quantifying soccer-specific skill could markedly improve both talent identification and development. Surprisingly, most protocols for talent identification in soccer still focus on the more generic athletic attributes of team sports, such as speed, strength, agility and endurance, rather than on a player’s technical skills. We used a multivariate methodology borrowed from evolutionary analyses of adaptation to develop our quantitative assessment of individual soccer-specific skill. We tested the performance of 40 individual academy-level players in eight different soccer-specific tasks across an age range of 13–18 years old. We first quantified the repeatability of each skill performance then explored the effects of age on soccer-specific skill, correlations between each of the pairs of skill tasks independent of age, and finally developed an individual metric of overall skill performance that could be easily used by coaches. All of our measured traits were highly repeatable when assessed over a short period and we found that an individual’s overall skill – as well as their performance in their best task – was strongly positively correlated with age. Most importantly, our study established a simple but comprehensive methodology for assessing skill performance in soccer players, thus allowing coaches to rapidly assess the relative abilities of their players, identify promising youths and work on eliminating skill deficits in players.  相似文献

黄艾珍  李辉 《幼儿教育》2006,(1)

本文简略报告了香港推行《表现指标》的实践探索研究及其成效。该研究历时三年半,共分两个阶段进行,前后共有15位专家、1200多位幼教工作者、上万名幼儿参与。第一阶段研究探索各种推行《表现指标》的实践经验和实践模式﹐出版了《学前教育机构表现指标“学与教范畴”应用指引》(简称《资源套》),供教师参考使用。第二阶段则在64个学前教育机构中尝试使用《资源套》并进行自我评估和自我完善﹐以进一步验证有关经验和模式﹐补充﹑完善《资源套》。该研究为香港特别行政区政府最终大面积推广《表现指标》扫清了主要障碍,做好了理论准备。本文分析了这一经验对内地推行新《纲要》的启示。  相似文献
