Background: Coaches are central to the development of the expert performer and similarly to continued lifelong participation in sport. Coaches are uniquely positioned to deliver specific technical and tactical instruction and mentoring programmes that support the psychological and social development of athletes in a challenging, goal-oriented and motivational environment. The current study aimed to qualitatively investigate current coach learning sources and coaches’ educational backgrounds in team sports in Ireland. Methods: Coaches from five team sports in Ireland were asked to complete an online questionnaire. Subsequently male coaches (n?=?19) from five team sports who completed the questionnaire and met the inclusion criteria were invited to attend a follow-up semi-structured interview. Inclusion criteria for coaches were that they possess at least 10 years’ experience coaching their sport and were coaching more than 4 hours per week. Results/Discussion: Formal coach education does not meet the needs of high performance coaches who rely more on self-directed learning and coaching experience as their main sources of CPD. Although prior playing experience at a high level is both valuable and desirable, there are concerns about fast-tracking of ex-players into high performance coaching roles. Conclusions: Preferred sources of education and the best learning environment for coaches of team sports in Ireland are more informal than formal. Further research is needed to examine how this learning is applied in a practical manner by examining coaching behaviours and the impact it has on the athlete development process.  相似文献

During the competitive season, soccer players are likely exposed to numerous factors that may disrupt the process of sleep. The current investigation looked to evaluate a practical sleep hygiene strategy (10-min showering at ~40°C before lights out), within a group of 11 youth soccer players in comparison to normal sleeping conditions (control). Each condition consisted of three days within a randomised crossover trial design. Sleep information was collected using a commercial wireless bedside sleep monitor. Measures of skin temperature were evaluated using iButton skin thermistors to establish both distal and proximal skin temperatures and distal to proximal gradient. The shower intervention elevated distal skin temperature by 1.1°C (95% CI: 0.1–2.1°C, p?=?.04) on average prior to lights out. The elevation in distal temperature was also present during the first 30-min following lights out (1.0°C, 95% CI: 0.4–1.6°C, p?<?.01). The distal to proximal gradient also showed a significant effect between the conditions within the first 30-min after lights out (0.7°C, 95% CI: 0.3–1.2°C, p?<?.01). On average the sleep latency of the youth soccer players was ?7-min lower (95% CI: ?13 to ?2?min, p?<?.01) and sleep efficiency +2% higher (95% CI: 1–3%; p?<?.01) in the shower condition. These findings demonstrate that a warm shower performed before lights out may offer a practical strategy to promote thermoregulatory changes that may advance sleep onset latency and improve sleep efficiency in athletes.  相似文献

Social identity – identity formed through membership in groups – may play an important role in regulating intrateam moral behaviour in youth sport (Bruner, M. W., Boardley, I., & Côté, J. (2014). Social identity and prosocial and antisocial behavior in youth sport. Psychology of Sport and Exercise, 15(1), 56–64. doi:10.1016/j.psychsport.2013.09.003). The aim of this study was to qualitatively examine this potential role through stimulated recall interviews with competitive youth-ice-hockey players. Twenty-three players (Mage = 13.27 years, SD = 1.79) who reported engaging in high, median or low frequency of antisocial teammate behaviour (determined through pre-screening with the Prosocial and Antisocial Behaviour in Sport Scale [Kavussanu, M., & Boardley, I. D. (2009). The prosocial and antisocial behavior in sport scale. Journal of Sport and Exercise Psychology, 31(1), 97–117. doi:10.1123/jsep.31.1.97]) were recruited from eight youth-ice-hockey teams in Canada. Interviews involved participants recalling their thoughts during prosocial/antisocial interactions with teammates, prompted by previously recorded video sequences of such incidents. Thematic analysis of interview data revealed all athletes – regardless of reported frequency of intrateam antisocial behaviour – felt prosocial interactions with teammates enhanced social identity. In contrast, the perceived influence of antisocial teammate behaviour on social identity differed depending on athletes’ reported frequency of intrateam antisocial behaviour; those reporting low and median frequencies described how such behaviour undermines social identity, whereas athletes reporting high frequency did not perceive this effect. The study findings highlight the potential importance of intrateam moral behaviour and social identity for youth-sport team functioning.  相似文献

This study characterises the relationship between gait variability and speed in runners using data from trunk accelerations in each axis.

Twelve participants of varying fitness ran on the treadmill with three sessions of six randomly ordered self-selected speeds. A VO2max test was conducted on the fourth session. Running gait was tracked with inertial sensors. The occurrence of a mid-range speed was analysed for the anterior–posterior, vertical and lateral directional coefficient of variation (CV) of root mean square (RMS) acceleration data.

One participant with noisy gait signals was omitted. The results show all remaining participants consistently showed significant quadratic U-shaped relationships between vertical RMS CV acceleration and speed. Neither anterior–posterior nor lateral RMS CV acceleration were clearly related to speed. These least variable gait speeds were similar to estimates of optimal speed derived from minimum cost of transport with speed.

In conclusion, there exists a mid-range speed for each runner with the least variable gait in the vertical direction, and this occurred significantly more often than would be expected by chance (P < 0.05). However, there are no prominent patterns for the anterior–posterior and lateral directions. This finding supports anecdotal evidence from runners and coaches concerning gait consistency.  相似文献

The benefits for a teacher in researching their own classroom have been well documented, but few reports have focused on how teachers make sense of what they see and hear during open-ended technology construction projects. This interpretive study has such a focus. It traces aspects of my learning trajectory as a teacher researcher in my Year Six classrooms, and aspects of improved classroom outcomes. In narrative voice I describe how my initial thinking about the building of acceptable scientific knowledge is modified through exploring the research literature and the strength of my students' ideas. My interpretation of videotape data of the collaboration process within group learning identifies the social dynamics which can influence the evolving nature of student's ideas in designing engineering structures. I describe how this research experience has influenced my planning and interaction with my students in the process of helping them to construct viable scientific knowledge.  相似文献

This article draws on findings from the first cross-national study of school exclusion in the four jurisdictions of the UK. It casts new light on the crucial aspects of children's education that lead to school exclusion. It investigates the reasons for the UK disparities, as well as the policy and practice in place. The focus of this article is on a detailed analysis of the policy context in Scotland, where official permanent exclusion reduced to an all-time low of just five cases in 2014/15. This is much lower than in Northern Ireland and Wales and in stark contrast to England, where exclusions have increased substantially since 2012. Our analysis seeks to understand Scotland's success in reducing exclusion and offers new insight into the ways in which national policies and local factors more generally shape schools and their practices and the consequent impacts for children and young people more broadly in the UK.  相似文献

ABSTRACT

Contract cheating occurs when a student outsources their assessment to a third party, regardless of the third party’s relationship with the student, or whether money is exchanged. In higher education, there is a widespread belief that assessment design is a solution to the problem of contract cheating and that authentic assessment tasks are particularly effective. This research analysed two datasets – 221 assignment orders placed on academic custom writing websites and 198 assessment tasks in which contract cheating was detected – to investigate if authentic assessment can assure academic integrity. The authenticity of assessments was determined using five factors derived from the literature: frequency, fidelity, complexity, real-world impact and feed forward. Our analysis found that assessment tasks with no, some, or all of the five authenticity factors are routinely outsourced by students.  相似文献
