The primary aim of this cross-sectional study was to compare subjective correlates of health, such as nutrition, self-esteem, sleep and stress, between adolescent elite athletes (n?=?625) and a reference group of adolescents (n?=?391) not involved in elite sports. A secondary aim was to study predictors for self-perceived stress. A questionnaire was e-mailed to all participants containing valid questions about competence-based self-esteem, nutrition, self-perceived stress and sleep. Our results show that adolescent elite athletes reported significantly (p?.001) lower self-perceived stress, competence-based self-esteem, a more varied diet and more time of sleep, compared to adolescents not involved in elite sports (Hedges’g 0.31–0.82). Female adolescent elite athletes and female adolescents, compared to their male peer group, reported poorer values for competence-based self-esteem (elite, Hedges’g 0.29; adolescents, Hedges’g 0.30) and self-perceived stress (elite, Hedges’g 0.63; adolescents, Hedges’g 0.60). The linear mixed effect model revealed several significant (p?.05) predictors (sex, general well-being, competence-based self-esteem, sleep during weekdays, BMI, training volume) associated with self-perceived stress in adolescent elite athletes. In conclusion, differences in correlates of health with a moderate to strong effect sizes were found between the two groups, where elite athletes surprisingly reported less stress, competence-based self-esteem, a more varied diet and more time of sleep. Even if injury risk is high in adolescent elite athletes and pressure from multiple stakeholders is evident, it appears that the athletes still have better conditions for a good subjective health, based on self-reported measures, compared to adolescents not involved in elite sports. 相似文献

This paper reports a case study on working closely with a secondary school, to enhance understanding of disruptive behaviour, through the use of bespoke Continuing Professional Development (CPD) materials. This project evolved from the researchers’ previous research on the extent to which teachers believe disruptive pupils can control their behaviour. A notable finding was the sizeable minority of teachers in both primary and secondary schools who appear to be unaware of the psychological underpinnings of disruptive behaviour. That is, that such behaviour frequently communicates unresolved emotional needs, rather than wilful defiance. The current project aims to develop, implement and evaluate CPD resources developed by the researchers, for a one-day staff training day at a secondary school in north England. Prior to training, school staff completed a questionnaire to “audit” their perceptions of disruptive behaviour in school. Following evaluation, the CPD materials will be made available to other schools. It is anticipated that the materials will enable greater mutual understanding and respect for the ways in which disruptive behaviour is perceived by practitioners and school staff. Moreover, they will provide an urgently needed means of facilitating a shared knowledge base and a shared language for addressing emotional barriers to learning. 相似文献

This study examined whether skill tests were predictive of status in junior Australian football. Players were recruited from the 2013 under 18 (U18) West Australian Football League competition and classified into two groups: elite (state U18 squad representative; n = 25; 17.9 ± 0.5 years) and subelite (nonstate U18 squad representative; n = 25; 17.3 ± 0.6 years). Both groups completed the Australian football kicking (AFK) and Australian football handballing (AFHB) tests, assessing kicking accuracy/ball speed and handballing accuracy on dominant and nondominant sides. A multivariate analysis of variance (MANOVA) modelled the main effect of “status”, whilst logistic regression models were built for the predictive analysis using the same test parameters. Between-group differences were noted across all parameters, with the combination of kicking accuracy and ball speed on the dominant and nondominant sides being the best predictor of status for the AFK test (wi = 0.25, AUC = 89.4%) and the combination of accuracy on the dominant and nondominant sides being the best predictor of status for the AFHB test (wi = 0.80, AUC = 88.4%). The AFK and AFHB tests are predictive of status, suggesting that their use is warranted as a means of talent identification in junior Australian football. 相似文献

Classifying subsequent injuries is of high importance in injury epidemiology since a previous injury has been reported to increase the risk of a new injury or increase the risk of a more severe injury. Multiple reports have shown that self-reported data provide an extensive view of an injury problem and add valuable information to the understanding of the athlete’s health. The purpose of this study was to display a method that can be used to facilitate classification of subsequent injuries and to discuss challenges faced when categorising subsequent injuries based on self-reported data. The suitability of a new model for Subsequent Injuries Adjusted for Self-reported data (SIAS model) was demonstrated with sport injury data from a cohort of 101 adolescent elite track & field athletes, followed over 52 weeks. A total number of 71 subsequent injuries were identified. Of all subsequent injuries, recurrent injuries represented 69.0% (n?=?49) and 31.0% (n?=?22) were classified as new injuries. The majority of subsequent injuries (n?=?60, 84.5%) occurred after athletes had recovered from a previous injury. Of all subsequent injuries, 15.5% (n?=?11) represented injuries where athletes had not fully recovered from a previous injury. Application of the SIAS model allows for classification of subsequent injuries based on self-reported data on the recovery level of the athletes, the injury onset and injury type. The developed SIAS model follows the consensus recommendations of injury definition, injury classification and is an attempt to increase the understanding of the complex relationship of subsequent injuries in self-reported data sets. 相似文献

The paper deals with the concept of ‘Critical Literacy’ in the context of VET teacher education. It focuses on the question of whether and how critical literacy can be developed drawing on elements of discourse research. This is illustrated by means of a higher educational setting, dealing with business administration textbook usage and research. The impact of our learning and teaching setting is illustrated via an empirical longitudinal study (three-phase pre-post design) of students doing a master’s degree in business education at an Austrian university. Data were initially collected directly before and after the university seminar using a semi-standardised questionnaire (n = 54). In order to obtain an insight into the sustainable impact of our discourse analysis course on students’ thought and actions, in the third phase of data collection, eight participants, who in the meantime had four months experience in VET schools as student teachers (120 h) were invited to a qualitative interview. The paper encompasses a theoretical discussion on the concept of critical literacy, applies it to the target group VET teacher students and shows empirical evidence on pros and cons of discourse analytical course design aiming at the critical literate teacher. 相似文献
