Relationship between vertical stiffness and soft-tissue injuries in professional Australian football
Daniel Sporri Matthew J. Pine Matthew L. Cameron Robert W. Spurrs Robert G. Bower 《Journal of sports sciences》2013,31(21):2425-2432
ABSTRACTSoft-tissue injuries are common in Australian football. Recently, literature has identified non-modifiable and modifiable risk factors, including vertical stiffness (Kvert). However, limitations regarding measurement frequency and duration exist; thus, further information is required about the role of Kvert as a modifiable risk factor for injury. This study examined the seasonal variation in Kvert and its relationship to soft-tissue injuries in professional Australian football. The mean Kvert and bilateral asymmetry were assessed and compared between injured and non-injured players. For the seasonal analysis, 56 players were tested across two seasons with no variation in bilateral asymmetry evident (p= 0.33). While there were generally no changes in Kvert, the value from the end of the second pre-season revealed 5% lower values than the mean of two seasons (p= 0.02). Considering the injury analysis, 21 lower-body soft-tissue injuries were recorded from 18 participants. No differences were recorded for mean Kvert between the injured and non-injured groups (p= 0.16–0.76). When assessing Kvert asymmetry, the injured group displayed a 4.5% higher value than the non-injured group at the end of the pre-season test (p= 0.03) but not at other time-points (p= 0.16–0.99). Higher Kvert bilateral asymmetry measures after the pre-season appear to be related to lower-body soft-tissue injury in professional Australian footballers. Medical and conditioning staff should consider this measure when trying to mitigate the onset of injury or identify at-risk players. 相似文献

ABSTRACTFundamental movement skills (FMS) are the basic building blocks of more advanced, complex movements required to participate in physical activity. This study examined FMS proficiency across the full range of Irish primary school children (n = 2098, 47% girls, age range 5–12 years). Participants were assessed using the Test of Gross Motor Development, 3rd edition (TGMD-3), Victorian Fundamental Movement skills manual, and the balance subtest from the Bruininks-Oseretsky Test of Motor Proficiency 2 (BOT-2). Independent sample t-tests and a one way between groups ANOVA with planned comparisons were used analyse sex and age differences. Mastery or near mastery of skills ranged from 16% for overhand throw, to 75.3% for run. Girls scored significantly higher than boys in the locomotor and balance subtests with the boys outperforming the girls in object control skills. Improvements in ability can be seen over time (F(8,1968) = 70.18, p < 0.001), with significant increases in FMS proficiency seen up to the age of 10, after which proficiency begins to decline. The findings demonstrate the low levels of FMS proficiency amongst Irish primary school children, the differences between sex that exist, and highlights the need for more programmes that focus on developing these FMS at an early age. 相似文献

Institutional policies and policy systems are vital to the well-being of institutions of higher education. While many institutions
dedicate time and resources to the development of key policies, the establishment of a well-designed and well-functioning
policy system is often neglected. We refer to the discrepancy between the importance of institutional policy systems and the
lack of time and resources devoted to them as the policy paradox. This article chronicles Utah Valley University’s policy improvement initiative as a guide for institutions of higher education
interested in improving institutional policy systems. 相似文献

The present study investigated whether young children are gullible and readily deceived by another's lies. Specifically, this study examined whether young children believe a lie teller's statement when the statement violates their developing knowledge of a distinction between reality and fantasy. In the first three experiments 3- to 6-year-olds (N = 293) were presented with either a story or a live staged event in which an individual made an implausible statement about a misdeed (claiming that a ghost jumped out of a book and broke a glass). A significant age effect was obtained: 5- and 6-year-olds tended to report that the individual who made the implausible statement had actually committed the misdeed, whereas 3- and 4-year-olds tended to accept the claim of the protagonist. Experiment 4 revealed that 5- and 6-year-olds (N = 43) not only disbelieved an individual's implausible statement but also inferred that the individual was lying and had a deceptive intent. In contrast, Experiment 5 revealed that 3- and 4-year-olds (N = 41) had difficulty disbelieving an individual's implausible claim about an inanimate object (i.e., the claim that a chair came alive and broke the glass). The findings suggest that 5- and 6-year-olds are not so gullible as previously thought, and that they use their well-developed real-world knowledge to detect scapegoating lies. In contrast, many younger children tend to believe another's implausible lies, perhaps due to the fact that the knowledge needed to detect such lies has not yet been consolidated. 相似文献

Continuing professional development (CPD) doctorate programmes may not be the only learning and development opportunities which universities and other organisations can provide for educational psychology practitioners (EPs). However, as Morris and Brightman pointed out in 2006, they are likely to continue as important sources for professional development for some years to come. Such programmes serve the purposes of providing continuing professional development for individuals, conferring higher status on the professional group and, for some, developing specialist skills and knowledge. This paper reports on two studies carried out nearly a decade apart. The first involved the collation of data from eight focus groups in London and the Home Counties who discussed the costs and benefits of setting up part‐time doctoral programmes for experienced practitioners in 1998, as discussed by Cameron in 1999, and the other was a small‐scale follow‐up survey in 2007 using a questionnaire which was based on the issues arising from the earlier focus group discussions and which was designed to explore consistent, changed and evolving views and opinions of practitioner EPs towards this extended form of EP professional training. While both studies uncovered evidence of the research–practice divide which has been a feature of EP practice for many decades, it was clear from the 2007 survey that much of the ambivalence of practitioners to the “academic dimension” of training, present in the first investigation, had dissipated and that national doctorate programmes for experienced practitioners had become a familiar feature of the educational and child psychology landscape. Some theory/research versus practice tensions still remain, however, and these, together with their likely implications for current and future developments in the profession, are also considered. Finally, some key issues arising from both the 1998 and the 2007 studies are used to illuminate the potential role of CPD doctorates in enabling EPs to address future challenges in the practice context. 相似文献

Investigating the causal association between unionism and organizational effectiveness 总被引:1,自引:0,他引:1
Kim S. Cameron 《Research in higher education》1985,23(4):387-411
In an earlier study, a negative relationship was found between faculty unionism and organizational effectiveness in colleges and universities. No research, however, has ever investigated potential causality in this relationship, that is, whether ineffectiveness leads to unionism or whether unionism leads to ineffectiveness. This study relies on assessments of organizational effectiveness in a sample of 4-year institutions in 1976, 1980, and 1983 to investigate the potential causal directionality of these two factors. The results of the analyses suggest that ineffectiveness leads to unionism, but that once unionized, organizational effectiveness does not seem to improve. 相似文献

The present research evaluated an intervention, derived from the "extended contact hypothesis," which aimed to change children's intergroup attitudes toward refugees. The study (n=253) tested 3 models of extended contact among 5- to 11-year-old children: dual identity, common ingroup identity, and decategorization. Children read friendship stories based upon these models featuring in- and outgroup members. Outgroup attitudes were significantly more positive in the extended contact conditions, compared with the control, and this was mediated by "inclusion of other in self." The dual identity intervention was the most effective extended contact model at improving outgroup attitudes. The effect of condition on outgroup intended behavior was moderated by subgroup identity. Implications for theoretically based prejudice-reduction interventions among children are discussed. 相似文献

Objective:Since concussion is the most common injury in ice hockey,the objective of the current study was to elucidate risk factors,specific mechanisms,and clinical presentations of concussion in men’s and women’s ice hockey.Methods:Ice hockey players from 5 institutions participating in the Concussion Assessment,Research,and Education Consortium were eligible for the current study.Participants who sustained a concussion outside of this sport were excluded.There were 332(250 males,82 females)athletes who participated in ice hockey,and 47(36 males,11 females)who sustained a concussion.Results:Previous concussion(odds ratio(OR)=2.00;95%confidence interval(95%CI):1.02‒3.91)was associated with increased incident concussion odds,while wearing a mouthguard was protective against incident concussion(OR=0.43;95%CI:0.22‒0.85).Overall,concussion mechanisms did not significantly differ between sexes.There were specific differences in how concussions presented clinically across male and female ice hockey players,however.Females(9.09%)were less likely than males(41.67%)to have a delayed symptom onset(p=0.045).Additionally,females took significantly longer to reach asymptomatic(p=0.015)and return-to-play clearance(p=0.005).Within the first 2 weeks post-concussion,86.11%of males reached asymptomatic,while only 45.50%of females reached the same phase of recovery.Most males(91.67%)were cleared for return to play within 3 weeks of their concussion,compared to less than half(45.50%)of females.Conclusion:The current study proposes possible risk factors,mechanisms,and clinical profiles to be validated in future concussions studies with larger female sample sizes.Understanding specific risk factors,concussion mechanisms,and clinical profiles of concussion in collegiate ice hockey may generate ideas for future concussion prevention or intervention studies. 相似文献

When do adolescents' dreams of promising journeys through high school translate into academic success? This monograph reports the results of a collaborative effort among sociologists and psychologists to systematically examine the role of schools and classrooms in disrupting or facilitating the link between adolescents' expectations for success in math and their subsequent progress in the early high school math curriculum. Our primary focus was on gendered patterns of socioeconomic inequality in math and how they are tethered to the school's peer culture and to students' perceptions of gender stereotyping in the classroom. To do this, this monograph advances Mindset × Context Theory. This orients research on educational equity to the reciprocal influence between students' psychological motivations and their school-based opportunities to enact those motivations. Mindset × Context Theory predicts that a student's mindset will be more strongly linked to developmental outcomes among groups of students who are at risk for poor outcomes, but only in a school or classroom context where there is sufficient need and support for the mindset. Our application of this theory centers on expectations for success in high school math as a foundational belief for students' math progress early in high school. We examine how this mindset varies across interpersonal and cultural dynamics in schools and classrooms. Following this perspective, we ask:
- 1. Which gender and socioeconomic identity groups showed the weakest or strongest links between expectations for success in math and progress through the math curriculum?
- 2. How did the school's peer culture shape the links between student expectations for success in math and math progress across gender and socioeconomic identity groups?
- 3. How did perceptions of classroom gender stereotyping shape the links between student expectations for success in math and math progress across gender and socioeconomic identity groups?
