The effects of physical exertion on decision-making performance of Australian football umpires

Decision-making is a key component of an umpire’s in-game performance, with each decision potentially having a direct impact on the result of the game. Additionally, umpires have to be physically fit to ensure they keep up with the gameplay. While research has identified the decision-making demands and running demands of umpires separately, few have explored the relationship between them. The aim of this investigation was to examine the relationship between physical exertion and decision-making performance of Australian football umpires at the sub-elite and junior levels. A total of 18 Australian football umpires (sub-elite, n = 10; junior n = 8) performed 10 × 300 m runs, with each repetition immediately followed by a video-based decision-making test, then 1 min of recovery. A Mann–Whitney U assessment indicated a significant difference between the sub-elite and junior level umpires for decision-making accuracy (U = 13.00, z = ?2.43, P = 0.016, r = ?0.5). However, there was no significant difference in response time (U = 28.00, z = ?1.07, P = 0.315, r = ?0.25). The sub-elite umpires completed the running efforts in significantly less time than the junior umpires (P < 0.05). Further, there was no significant correlation between decision-making performance and running times for either skill level (P > 0.05). This suggests decision-making performance may not be affected by physical exertion. Therefore, it may be suggested coaches of football umpires allocate more time to the decision-making development of their umpires instead of focusing largely on the physical fitness side, as is currently the trend.  相似文献

The developmental and professional activities of female international soccer players from five high-performing nations

ABSTRACT

We study the developmental and professional activities engaged in by 86 female adult soccer players from the senior national teams of Australia, Canada, England, Sweden, and the United States of America. Players completed the Participation History Questionnaire (PHQ) to elicit the amount and type of activities engaged in across their developmental and professional years, including milestones, soccer-specific activity and engagement in other sport activity. Greater specialisation than diversification characterised their childhood developmental activities, including all players starting in soccer in childhood and accumulating more hours in soccer activity than other sports during this period. However, interindividual variation further characterised these childhood activities, with a proportion of players diversifying into other sports and/or soccer play to a greater or lesser degree during childhood when compared to the other players. The amount of coach-led soccer practice increased for all players across their development culminating in an average of 15–16 h/wk across a 40-week season in early adulthood. In contrast, the amount of engagement in other sports and soccer peer-led play varied between players but generally decreased across adolescence to negligible amounts in late adolescence. Findings are commensurate with the deliberate practice framework and early engagement.  相似文献

Correlates of Sustained Volunteering: Advocacy for Students with Disabilities     

Samantha E. Goldman  Meghan M. Burke  Carolyn Q. Mason  Robert M. Hodapp 《Exceptionality》2017,25(1):40-53

Parents of students with disabilities often receive support from special education advocates, who may be trained through a variety of programs. Using a web-based survey, this study examined the postgraduation advocacy activities of 83 graduates of one such volunteer advocacy training program. In the one to four years after program graduation, 63.8% (53 of 83) of the graduates advocated for one or more families; these sustained advocates reported stable rates of advocacy over time, and advocates performed activities that were either family-focused or school-focused. For graduates who advocated post-training, amounts of advocacy were positively related to satisfaction with advocating and with higher levels of involvement with other advocates and with the broader disability community. Compared to those not advocating after graduating, sustained advocates reported greater advocacy-role identities, increased involvement in disability groups, and higher likelihood to advocate in the upcoming year. Future research and practice implications are discussed.  相似文献   

Exploitation or opportunity? Student perceptions of internships in enhancing employability skills     

Henrietta O’Connor  Maxine Bodicoat 《British Journal of Sociology of Education》2017,38(4):435-449

Internships are now widely promoted as a valuable means of enhancing graduate employability. However, little is known about student perceptions of internships. Drawing on data from a pre-1992 university, two types of graduate are identified: engagers and disengagers. The engagers valued internship opportunities while the disengagers perceived these roles as exploitative and worthless. Few were able to distinguish paid, structured internship opportunities from unpaid, exploitative roles. We conclude that higher education institutes need to be more proactive in extolling the value of paid internships to all students and not just those most likely to engage with their services.  相似文献   

Does First Sex Really “Just Happen?” A Retrospective Exploratory Study of Sexual Debut Among American Adolescents     

Lisa D. Lieberman  Eva S. Goldfarb  Samantha Kwiatkowski  Paul Santos 《American journal of sexuality education》2017,12(3):237-256

First sex marks a significant transition for most adolescents, yet teens often report that it was unplanned. Seventy-four college students participated in exploratory focus groups about their first sex. Although initially asked whether their first sex was spontaneous or planned, many participants revealed evidence of forethought or anticipation, signifying a third option, anticipation. This study suggests that the development and timing of sexual health messages should build on the apparent, albeit often unacknowledged, planning and thought that accompany the transition to first sex. Specifically, during the time immediately preceding first sex, young people might be particularly open to such messages.  相似文献
