Recent theories suggest that negative effects of fatigue on performance are determined by perception of effort and motivation rather than being directly caused by reaching physiological limits. In the current experiment, the influence of motivation on fatigue-induced decrements in soccer performance was experimentally investigated. Sixty amateur soccer players performed a validated soccer-passing test before and after a fatigue protocol. Results showed that players’ motivation and performance decreased after the fatigue protocol for players in the control group. In contrast, players in the motivation group (i.e., with motivation experimentally induced after the fatigue protocol) were able to uphold their motivation and increase their performance. These results indicate that motivation plays a crucial role in performance under fatigue, as fatigue-induced decrements in soccer passing performance can be counteracted by high levels of motivation. Future research may explore the limits of this counteracting effect and extend findings to other relevant performance aspects.  相似文献   

Football,Place, and Community in a New Zealand Mining Town, 1877–1939     

Charles Little 《国际体育史杂志》2017,34(10):915-934

Abstract

Resource towns (such as lumber camps, power plants, and mining towns) are by their very nature peripheral. They frequently exist in a space of isolation, not only geographically but also culturally as well. The South Island mining town of Kaitangata is a classic example of this process – an industrial, working class, and heavily migrant community positioned within an otherwise agricultural, conservation, and homogenous tract of rural New Zealand. Kaitangata, in the words of one writer, ‘possessed a unique character and pattern of social interaction’ that marked it out from its immediate environment. One way in which these differences manifested themselves was in the sporting activities of the town. In a part of the world where rugby union held absolute hegemony, the town broke the mould by also fielding teams in association football, rugby league, and even Australian Rules football (distinguishing itself as the only town outside of the provincial capital of Dunedin where these three sports obtained a foothold). This paper analyses how these sporting activities contributed to a unique sense of space, addressing themes including class, ethnicity, masculinity, and identity.  相似文献   

Effect of the look-up line on the gaze and head orientation of elite ice hockey players

Abstract

A “look-up line” (LUL) has been proposed for ice hockey, which is an orange 1?m (40′) warning line (WL) painted on the ice at the base of the boards. The LUL purports to provide an early warning to players to keep their head up prior to and as they are being checked. We determined if players looked up more on a rink with the LUL compared to a traditional Control rink. Elite offensive (O) and defensive (D) players competed 1 vs. 1, while wearing an eye tracker that recorded their quiet eye (QE) and fixation and tracking (F-T) and an electrogoniometer that measured head angle. External cameras recorded skate duration during four skate phases: P1 preparation, P2 decision-making, P3 cut to boards, P4 contact. The QE was the final fixation prior to contact between O and D as they skated towards and across the WL during P3 and P4. Skate phase durations (%) did not differ by rink or rink by position. More QE and F-T occurred on the WL on the LUL rink than on the Control. The expected increase in head angle on the LUL rink did not occur during P3 or P4. Post-hoc results also showed O and D skated further from the boards on the LUL rink, suggesting the players preferred to control the puck on white ice, rather than the orange colour of the LUL rink. More research is needed to determine if these results apply to the competitive setting.  相似文献

Evaluation of a learning analytics tool for supporting teachers in the creation and evaluation of accessible and quality open educational resources     

Cecilia Avila  Silvia Baldiris  Ramon Fabregat  Sabine Graf 《British journal of educational technology : journal of the Council for Educational Technology》2020,51(4):1019-1038

The learning analytics (LA) field seeks to analyze data about students’ interactions, and it has been applied in the development of tools for supporting both learning and teaching processes. Recent research has paid attention on how LA may benefit teachers in the creation of educational resources. However, most of the research on LA solutions is carried out to support teachers in analyzing students’ behavior data collected as they interact with virtual learning environments. While solutions to support teachers in different virtual learning and teaching contexts have become important, to date little research has been done on how LA solutions can help teachers to create and evaluate Open Educational Resources (OERs). This study aims at presenting the evaluation of a LA tool for supporting teachers in the creation and evaluation of accessible and quality OERs considering that both processes fall within the competences that teachers can acquire and strengthen by participating as authors (creation) and evaluators (evaluation) of OERs. The study was conducted with Colombian teachers and the results obtained highlight the positive effect the tool had on the teachers’ acquisition of the competences and the positive attitude they had toward using the tool.  相似文献

Far from Fifty-Fifty: Legal Measures and the Relative Lack of Women in Powerful Decision-Making Positions in Germany’s Broadcasting Sector     

Romy Fröhlich  Sabine Baudisch 《广播与电子媒介杂志》2016,60(2):305-330

A gender-equal organization of institutions requires adequately qualified women to be equally present on every hierarchical/functional level. In light of this, the authors evaluate how women participate in leading managerial and supervisory positions of administrative relevance, i.e., beyond editorial departments, in public and private broadcasting corporations and organizations in Germany. The study comprises an examination and comparison of existing legal requirements/regulations for gender equality on the supervisory councils of Germany’s broadcasting corporations/organizations and contributes to the analysis on the contemporary politics of gender in Germany’s broadcasting sector. It is the first study of its kind.  相似文献   

Perspectives of students with autism on their participation in a peer-mediated intervention     

Jessica Z. Zanuttini  Cathy Little 《Support for Learning》2021,36(4):572-593

The article describes research into the perspectives of students with autism regarding their participation as the target participants in a peer-mediated social communication intervention. Questionnaires were administered to four elementary-aged students with autism before and after their involvement in the intervention. The students' parents and teachers also completed questionnaires about the students' participation in the intervention. Through the use of these questionnaires, we gained an insight into students' experiences with the intervention, which elements of the intervention they found most enjoyable and most effective, and the perceived impacts of the intervention on their social communication behaviours. Qualitative and quantitative analyses of the questionnaire data revealed that all four students with autism enjoyed participating in the peer-mediated intervention sessions, felt that their social communication behaviours had improved as a result of their involvement, and would like to be involved in similar sessions in the future. Implications for parents and educators who support the social communication of children with autism are explored.  相似文献
