To ensure that elite adolescent athletes meet their unique training, growth and maturation demands, it is imperative to have access to valid measures of energy intake. Contemporary methods demand close attention-to-detail, meaning that athletes often do not fully adhere to real-time protocols. This study represents the first investigation of a real-time dietary assessment designed using a comprehensive behaviour change framework (COM-B). In a crossover design, 12 elite adolescent male rugby players recorded their energy intake via an estimated food diary (est-FD) and photography-based mobile assessment (‘Snap-n-Send’), combined with a 24-h dietary recall interview. Two 4-day assessment periods were divided into three separate recording environments: 96?h free-living and researcher-observed; 72?h free-living and 10?h researcher-observed. Assessment periods were one month apart. All foods and beverages were provided and weighed by the research team to quantify actual intakes. ‘Snap-n-Send’ reported a small mean bias for under-reporting across 96?h (?0.75?MJ?day^?1; 95% confidence interval [CI] for bias?=??5.7% to ?2.2%, p?<?.001), 72?h (?0.76?MJ?day^?1; 95% CI for bias?=??5.6% to ?2.1%, p?=?.004) and 10?h (?0.72?MJ?day^?1; 95% CI for bias?=??8.1% to ?0.1%; p?=?.067) environments. The est-FD reported a moderate mean bias for under-reporting across 96?h (?2.89?MJ?day^?1; 95% CI for bias?=??17.9% to ?10.2%; p?<?.001), 72?h (?2.88?MJ?day^?1; 95% CI for bias?=??17.9% to ?10.1%; p?<?.001) and 10?h (?2.52?MJ?day^?1;?26.1% to ?5.3%; p?=?.023) environments. Results evidence the ability of ‘Snap-n-Send’ to accurately assess the diet of elite adolescent athletes, signalling the exciting promise of this comprehensive and theoretical behavioural approach within valid dietary assessment.  相似文献   

A Tale of Two Presidents: The Rise and Fall of Division I Athletics at Birmingham-Southern College     

Jim Watkins 《国际体育史杂志》2017,34(11):1088-1111

Abstract

In 1999, Birmingham-Southern College (BSC) announced that they were leaving the National Association of Intercollegiate Athletics to join the highest rank of the National Collegiate Athletic Association-Division I. While competing in Division I, the size of BSC’s athletic budget was in the bottom 10 per cent. By 2006, the Board of Trustees at Birmingham-Southern voted to reclassify to Division III. Why did Birmingham-Southern decide to enter Division I? How did the academic mission of Birmingham-Southern play a role in the rise to Division I or the fall to Division III? What role, if any, did the presidents of Birmingham-Southern play in its joining and leaving Division I? One reason Birmingham-Southern decided to compete at the Division I level was because their leaders believed in the ‘Flutie Factor’, which is the concept that athletic success will benefit the entire institution. BSC’s transition into Division I during 1999 suggests that the commercialization of big-time college athletics encourages presidents to overemphasize athletics, and that they face little opposition when doing so. Moreover, the opposition to BSC’s reclassification into Division III during 2006 suggests that presidents face more resistance when attempting to lead their college into a less prestigious level of competition, even if the move better fits the college’s academic mission.  相似文献
