Zeitökonomische Aspekte der Nachfrage nach Vereinsleichtathletik im europäischen Vergleich     

Dr. phil. Jens Flatau  Werner Pitsch  Dirk Bogendörfer  Eike Emrich 《Sportwissenschaft》2009,39(2):110-119

In a joint project involving European association staff and sports scientists, basic structural data were collected on British, Swedish, Spanish and German athletics clubs to be used for analysis of hypotheses concerning conditions of participation in sports clubs, particularly by children and adolescents. The results showed clear differences in organizational level as well as membership and activity structures in comparisons between European countries and within Germany. The findings revealed the differential functions and significance of sports clubs in the context of the respective institutions and cultures.  相似文献   

Decision-making skills and deliberate practice in elite association football referees     

MacMahon C  Helsen WF  Starkes JL  Weston M 《Journal of sports sciences》2007,25(1):65-78

We examined sport expertise as a function of role. In study 1, referees were better than players in a video-based decision-making task. This provides evidence that there are role-specific skills within one domain or sport. In study 2, we examined the training activities that could be influential in the development of skills in sports officials. Elite association football (soccer) referees retrospectively reported time spent in and perceptions of training activities for three periods: their first year of formal refereeing, 1998 (before formal training programmes were available), and the current year (2003). This allowed us to examine an area of skill with a limited culture of practice, where performance simulations with direct feedback are usually not feasible. The results showed that referees specialize early and, as they develop, they engage in greater volumes and types of training. Competitive match refereeing is considered a relevant activity for skill acquisition that does not fit Ericsson and colleagues' (1993) original definition of deliberate practice. Our findings indicate that actual performance is a significant activity for skill acquisition and refinement.  相似文献   

Could Slackline Training Complement the FIFA 11+ Programme Regarding Training of Neuromuscular Control?     

Tobias Jäger  Julian Kiefer  Inge Werner 《European Journal of Sport Science》2017,17(8):1021-1028

The current study compared changes in neuromuscular control between slackline training and the stabilization training elements of the FIFA 11+ programme. Twenty-five students in 2 groups performed a 12-unit training programme. The slackline training group (n?=?13) exclusively trained with a slackline. The stabilization training group (n?=?12) practised exercises as described in the second part of the FIFA 11+ programme. Improvements in balance were assessed using three tests for dynamic, quasi-static, and perturbed postural control: the star excursion balance test (SEBT), the closed-eye single-leg stance, and the MFT S3-Check. Both groups significantly improved the stability and sensorimotor index of the MFT S3-Check (p?<?.001), their range on the SEBT (p?<?.001), and the duration of closed-eye single-leg stance (p?<?.001). The group?×?training interaction was significant for the MFT S3-Check (stability index: p?=?.042; sensorimotor index: p?=?.004) and the SEBT (dominant leg: p?=?.003; averaged both legs: p?=?.016), with the slackline training group showing a larger training effect than the stabilization training group. The results of the present study suggest that slackline training offers similar – or better – improvements in neuromuscular control as the FIFA 11+ warm-up programme. If compliance with the FIFA 11+ programme is declining, then slacklining might offer an alternative approach to reach the training goals of improved sensorimotor control.  相似文献

Factors Associated with Teenagers’ Willingness to Volunteer with Elderly Persons: Application of the Theory of Planned Behavior (TPB)     

Yehudit Reuveni  Perla Werner 《Educational gerontology》2015,41(9):623-634

The purpose of this study was to investigate the factors associated with teenagers’ willingness to volunteer with elderly persons using an expanded model of the Theory of Planned Behavior (TPB). Participants consisted of 258 ninth-grade students at a large high school in the northern part of Israel. Participants completed a structured questionnaire consisting of 52 items, which examined their attitudes, subjective norms, perceived behavioral control, past behavior, personal identity, and perceived moral obligation. Their willingness to volunteer with elderly persons was assessed using six vignettes, varying in the severity of the elderly person's health and functional conditions described. Additionally, the students’ sociodemographic variables were examined. Overall, students’ willingness to volunteer with elderly persons was low; however, it increased when the elderly person in the vignette was described as relatively healthy. Statistically significant relationships were found between willingness to volunteer and personal identity, as well as between willingness to volunteer and attitudes toward volunteering with elderly persons. A statistically significant but moderate relationship was found between willingness to volunteer and subjective norms. Multiple regression analyses showed that attitudes, subjective norms, and personal identity were the main predictors of willingness to volunteer with elderly persons, explaining 58% of the variance. The expanded model of the Theory of Planned Behavior provided an appropriate framework for understanding the factors associated with teenagers’ willingness to volunteer with elderly persons. Our findings stress the need to develop educational intervention programs regarding gerontologically-related subjects and to disseminate them among the population in general, and among youth in particular.  相似文献

Reducing adolescents' involvement with relational aggression: Evaluating the effectiveness of the Creating A Safe School (CASS) intervention     

Charisse L. Nixon  Nicole E. Werner 《Psychology in the schools》2010,47(6):606-620

This study examined the effectiveness of a comprehensive, school‐based intervention program, Creating A Safe School (CASS; The Ophelia Project) designed to reduce relational aggression (RA) and relational victimization (RV). Sixth‐grade students (N = 406) were surveyed before and after the intervention. Program effects were tested using a repeated‐measures design. Results revealed significant reductions in RA and RV among students who reported initially high levels of involvement. Findings also showed that decreasing approval of RA accounted for a significant amount of variance in changes in RA between pre‐ and posttest. These results provide initial evidence of the effectiveness of the CASS intervention model in reducing RA among early adolescents. © 2010 Wiley Periodicals, Inc.  相似文献
