This study targeted to examine the effect of the ToyBox-intervention, a kindergarten-based, family-involved intervention, aiming to improve preschooler’s energy-related behaviours (e.g., physical activity) on motor performance ability. Physical activity sessions, classroom activities, environmental changes and tools for parents were the components of the 1-year intervention. The intervention and control were cluster-randomised, and children’s anthropometry and two motor test items (jumping from side to side, JSS and standing long jump, SLJ) were assessed. A total of 1293 (4.6 ± 0.69 years; 52% boys) from 45 kindergartens in Germany were included (intervention, n = 863; control, n = 430). The effect was assessed using generalised estimating equation. The intervention group showed a better improvement in JSS (Estimate 2.19 jumps, P = 0.01) and tended to improve better in SLJ (Estimate 2.73 cm, P = 0.08). The intervention was more effective in boys with respect to SLJ (P of interaction effect = 0.01). Children aged <4.5 years did not show a significant benefit while older children improved (JSS, Estimate 3.38 jumps, P = 0.004; SLJ, Estimate 4.18 cm, P = 0.04). Children with low socio-economic status improved in JSS (Estimate 5.98 jumps, P = 0.0001). The ToyBox-intervention offers an effective strategy to improve specific components of motor performance ability in early childhood. Future programmes should consider additional strategies specifically targeting girls and younger aged children.

Sport participation in France is characterized by deep trends that make more and more French people taking part in sport activities,and broaden the types of sports and physical activity they take part in. However,sport remains differentiated in the sense that strong differences can be observed between sports,and between individuals. Along these deep trends more micro-trends can be observed involving ei-ther the purpose of sport participation (e. g. search for adventure and fun)or the forms and modalities of this participation (e. g. individualisation and technologisation). Furthermore,sport participants are in-creasingly difficult to satisfy as they can mix several of these micro-trends,sometimes in a contradictory fashion,demonstrate multiple interests for various leisure sports and activities,which constitutes a signifi-cant challenge for leisure sport organisations. 相似文献

新时代对体育强国和体育法治建设提出了新要求,行政执法作为体育强国建设的重要抓手也面临着方式革新的机遇和挑战。简政放权背景下,体育执法面临着“应不应该管、怎样管”的尴尬处境,广为体育行政执法主体运用的强制性执法手段极易加剧执法矛盾,执法的社会效果得不到保障。由于传统执法方式难以适应新时代体育市场监管的现实需要,革新体育行政执法方式就显得尤为必要。面对时代课题,应遵照由“形式优化”到“实质革新”的逻辑,并树立行政平衡、服务合作和正当程序的理念,从引入信用工具、推广非强制性执法和全程说理式执法3个方面推进改革,实现体育行政执法方式的精简化、多元化和法治化。 相似文献

AbstractThis study examined staff motivation, satisfaction, and job performance among the librarians and library staff in six selected university libraries in Nigeria. The target population for the study includes the professionals and nonprofessional library staff. A total enumeration sampling technique was used to select 180 respondents, which represent the sample for the study. Data was collected using a self-designed questionnaire titled “Staff Motivation, Satisfaction and Job Performance Questionnaire” (SMSJPQ). Six research questions were developed and answered by the study. The results indicate that librarian and library staff are highly motivated with regular pay while the least motivational factor is frequent interaction with their friends. Library staff are primarily satisfied with their jobs when they are in constant link with their friends. Professional library staff significantly experience better work motivation than their nonprofessional counterparts. Significant correlation exists between staff motivation and job performance and between job satisfaction and job performance. In addition, the two factors (motivation and satisfaction) exert significant contribution to the determinant of librarians and library staff job performance. Based on the findings, the study recommended improvement in the level of motivation of nonprofessionals so that the significant difference with the professional counterpart would not be so much pronounced. 相似文献

The development of artificial intelligence (AI) technology expands the boundary of business practice, inducing the emergence and application of business intelligence (BI) that has promoted the transformation of information techniques to optimize business decision and operation. However, there is a lack of theoretical consensus and measurement of the technology embedded in BI at present. This study exploratively develops the Sense-Transform-Drive (STD) conceptual model of BI based on dynamic capabilities theory and organizational evolutionary theory to explain the core BI capabilities. By using factoring analysis and structural equation modeling analysis, we extract the latent constructs and empirically verify the validity of the STD model and further examine the correlation and mode of interaction of the three core BI capabilities and the impact of BI application on firm performance in the real economy with a sample contextual to Chinese business practices. The study results show that there are direct and high-intensity cumulative positive effects among the structural components of the STD conceptual model and BI-related dynamic capabilities can enhance operating efficiency and firm performance. 相似文献

Understanding factors that motivate young athletes to continue participation in sport can help key stakeholders cultivate an environment that fosters long-term participation. This investigation sought to determine the performance and participation factors that influenced continued participation in junior cricket. Administration-level data were collected each annual season across a seven-year period by a community-level junior cricket association in Australia and analysed to identify the performance and participation-based predictors of player retention. All players were males aged <16 years. Players were categorised according to whether they remained in (or departed from) the association at the end of each playing season. A multivariate logistic regression model with a stepwise variable selection was employed to identify significant independent predictors of player retention. The number of innings batted and overs bowled were significant participation-related contributors to junior cricket player retention. Performance factors such as the number of wickets taken and the number of runs scored also significantly influenced player retention. Finally, team age group, the number of previous seasons played and age were also significant factors in player retention. This demonstrates that sufficient opportunity for children to participate in the game and expression of skills competence are key factors for retention in cricket. 相似文献
