Purpose: The purpose of this study was to analyze tracking and stability of motor coordination in children from age 6 years to ages 9 and 13 years. Method: Data were from the Copenhagen School Child Intervention Study. Motor coordination (MC) was measured using the körperkoordinationstest für Kinder (KTK) test. The crude performance score on every item was converted into a standardized “score” based on the original German reference study, which was used to generate a total standardized motor coordination (MQ) score. The MQ scores, which represented children's level of gross MC, were classified as low (MQ score < 85), normal (MQ score = 85–115), or high (MQ score>115). Pearson correlation was used to calculate the tracking coefficients of each KTK element and MQ score, and weighted kappa was used to analyze maintenance in MC classification groups. Mixed-effects logistic regression analyses were performed to examine the odds of remaining in the low MC group over time based on body mass index (BMI), weight, and height tertiles. Results: Tracking coefficients among the MQ score and each KTK element at different ages were moderate (r>.35). Children in the highest BMI and weight tertiles had a 5.44 and 5.15 times greater chance to be in the lower MC classification group during the 7-year follow-up, respectively, in comparison with children in their lowest tertiles. Conclusion: MC tracked moderately through childhood to early adolescence. Because heavier children had a greater chance to be in the lower MC group at older ages, intervention may be useful at earlier ages for those with lower MC and disadvantageous weight status.  相似文献   

Virtual Patriot Games: American Football in The Times of London, 1888–1910

Abstract

This study examines the American football press coverage in the Times of London from 1888 to November 1910. The time span covers the paper’s first mention of the game to the first game played in England. This period also coincides with increasing anxiety about the strength of the British Empire and unwanted American influences. During this time, athletic contests between the two nations turned into sites for the construction of national identities. Adapting the sport scholar Emma Poulton’s concept of ‘mediated patriot games’, the author argues that the American football coverage of the Times of London could be considered ‘virtual patriot games’, as the absence of domestic American football teams did not allow for direct competition. Two related narrative elements. The stories in the Times framed gridiron football as the pastime of the ‘other’, including translating rules and comparing the merits of rugby and American football. The reports also focused on the American game’s violence, confirming older traditions in British imaginations of America. Advancements in communication technologies, especially the telegraphic wire, were critical for the immediacy with which British readers consumed American sporting news. Contrary to current scholarship, British interpretations of American culture through gridiron football developed much earlier than the post-1970s information age.  相似文献
