Objectives: To improve well-being and performance indicators in a group of Australian Football League (AFL) players via a six-week sleep optimisation programme. Design: Prospective intervention study following observations suggestive of reduced sleep and excessive daytime sleepiness in an AFL group. Methods: Athletes from the Adelaide Football Club were invited to participate if they had played AFL senior-level football for 1–5 years, or if they had excessive daytime sleepiness (Epworth Sleepiness Scale [ESS] >10), measured via ESS. An initial education session explained normal sleep needs, and how to achieve increased sleep duration and quality. Participants (n?=?25) received ongoing feedback on their sleep, and a mid-programme education and feedback session. Sleep duration, quality and related outcomes were measured during week one and at the conclusion of the six-week intervention period using sleep diaries, actigraphy, ESS, Pittsburgh Sleep Quality Index, Profile of Mood States, Training Distress Scale, Perceived Stress Scale and the Psychomotor Vigilance Task. Results: Sleep diaries demonstrated an increase in total sleep time of approximately 20?min (498.8?±?53.8 to 518.7?±?34.3; p?<?.05) and a 2% increase in sleep efficiency (p?<?0.05). There was a corresponding increase in vigour (p?<?0.001) and decrease in fatigue (p?<?0.05). Conclusions: Improvements in measures of sleep efficiency, fatigue and vigour indicate that a sleep optimisation programme may improve athletes’ well-being. More research is required into the effects of sleep optimisation on athletic performance. 相似文献

From October 22 to 30, 2011, the 13th China Wuqiao Acrobatic Festival was held in Shijiazhuang, north China’s Hebei province.Co-organized by the Ministry of Culture of China and Hebei People’s Provincial Government, this biennial event featured the theme of "developing acrobatic art, facilitating international exchanges,promoting economic and social development,and enriching people’s cultural life". This year,the festival attracted more than 200 acrobats from 27 circus companies from 17 countries and regions around the world, including Russia,Canada, USA, DPRK, Australia and France, who 相似文献

This article describes a new instrument for the measurement of adaptive behavior that is administered directly to the child. It was designed for brief administration, to be educationally relevant, and to measure these five domains of adaptive behavior: Language Development, Independent Functioning, Family Role Performance and Economic-Vocational Activity, and Socialization. An initial study of test-retest reliability indicates the instrument has high reliability. 相似文献

Beery's Developmental Test of Visual-Motor Integration was individually administered to 193 school-age children. Test protocols were factor analyzed by a principal component solution. Four factors were obtained, indicating that the test does not measure a unitary dimension of perceptual-motor development, but rather four distinct levels or stages for the age range of children investigated. The structural features of the designs that make up the test were used to define the factors. It is argued that a more useful interpretation of performance on this test would be one that designates visualmotor processing in terms of levels, not age equivalents. 相似文献

The article discusses an empirical study that was conducted by the authors, in which they surveyed focus groups of young innovative entrepreneurs who are at different stages of creating their own projects. The authors devote particular attention to how training programs for the founders and staff should be implemented as the startup develops from its early phases into a sustainable-growth business. 相似文献

In this reflective piece the author focuses on the meaning that he made of inclusion in a book that was published almost twenty years ago. He then reflects on the meaning he makes of the current situation. He explores the problematic nature of the concept of inclusion, whether labels actually enable inclusion, research-informed implications of inclusion for those who do not experience SEND and the damaging impact of hyperaccountability and marketisation. He proposes that we may find future solutions by embracing complexities and educating for diversities. 相似文献

In collaborative problem solving, children produce and evaluate arguments for proposals. We investigated whether 3- and 5-year-olds (N = 192) can produce and evaluate arguments against those arguments (i.e., counter-arguments). In Study 1, each child within a peer dyad was privately given a reason to prefer one over another solution to a task. One child, however, was given further information that would refute the reasoning of their partner. Five-year-olds, but not 3-year-olds, identified and produced valid and relevant counter-arguments. In Study 2, 3-year-olds were given discourse training (discourse that contrasted valid and invalid counter-arguments) and then given the same problem-solving tasks. After training, 3-year-olds could also identify and produce valid and relevant counter-arguments. Thus, participating in discourse about reasons facilitates children’s counter-argumentation. 相似文献

研究以政府协调治理为理论基础,以“主体-场景-行动”为治理逻辑的分析框架,指出马拉松赛事风险治理的困境,提出马拉松赛事风险政府协调治理的实现路径。研究认为,马拉松赛事风险治理存在治理主体对赛事风险治理认识不够、赛事风险场景的精细划分比较笼统、赛事风险应急合作治理行动的基础支撑条件不完善等困境。应从更新治理理念、转变治理主体的角色认识,优化场景划分、夯实场景的精细化和数字化;强化行动效益,夯实赛事风险治理的行动基础3个方面推进治理。 相似文献

The purpose of the study was to compare young sprint and distance runners for changes in their cardiac dimensions with increased age (10–17 years) or body surface area (1–2 m2). Echocardiographic dimensions were obtained on 73 male track athletes competing in the 1983 National Age Group Track and Field Association championships. Each group of athletes was also compared with a hypothetical normal population (matched for weight and age) generated from prediction equations derived by Henry, Gardin, & Ware (1980). The cardiac dimensions examined were: Left ventricular internal diameter, left ventricular posterior wall thickness, and interventricular septum thickness. The male distance runners (n = 38) had a significantly greater increase in left ventricular posterior wall thickness and interventricular septum thickness with increasing age or increasing body surface area compared to the sprinters (n = 35) or compared to the predicted normal population. The left ventricular internal diameter was not significantly different between the groups. These results indicate that the hearts of male distance runners are undergoing a training hypertrophy whereas the hearts of sprinters are no different than hearts in a normal population. The changes in cardiac dimensions of these young athletes run counter to the generalizations stated for adult athletes: That endurance training enlarges the left ventricular internal diameter, but does not increase the left ventricular posterior wall or interventricular septum thickness. 相似文献
