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

Sedentary behaviour (SB) has recently emerged as an independent risk factor for different health outcomes. Older adults accumulate long time in SB. Understanding the role that SB plays on health is crucial for a successful aging. This short systematic review summarizes the current evidence related to the effects of objectively measured SB on frailty, physical performance and mortality in adults ≥60?years old. The literature search produced 271 records for physical performance (n?=?119), frailty (n?=?31), and mortality (n?=?121). Finally, only 13 articles fulfilled the inclusion criteria and were included in this review. All articles but one included in the physical performance section (n?=?9) showed a negative association between longer time spent in SB and physical performance. A significant association of SB with higher odds of frailty was found, however this association disappeared after adjusting for cognitive status. Lastly, two of the three included studies showed positive associations between SB and mortality, but this effect decreased or even disappeared in the more adjusted models. In conclusion, there is consistency that SB is negatively associated with physical performance. However, the relationship between objectively measured SB and frailty incidence and mortality rates remains unclear and deserves further research. The use of homogenous criteria to assess SB and the inclusion of more robust research designs will help clarifying the independent effects that SB could have on physical performance, frailty, and mortality. This will ultimately help designing more efficient and comprehensive physical activity guidelines for older adults. 相似文献

This study examines the linguistic and cultural intersections of recently arrived Somali Bantu refugee students in South Texas through the lens of border theory. The use of Spanish in the homes of refugee families is explored in addition to ways in which an educator used testimonios to honor students’ migration experiences. Findings show how specific approaches used in schools that affirm both the receiving communities’ and the new arrivals' local knowledge can have a lasting impact on literacy acquisition and resettlement experiences. Findings from this study also illuminate the potential impact of educators who develop a critical, inquiry stance by embedding multiple entry points for students to cross social, cultural, linguistic, and curricular borders in school. 相似文献

Abstract The gender sexual politics of Liu Yu‐hsiu has been pivotal in the hegemonic ascendancy of Taiwan state feminism in recent years. Through an examination of Liu’s psychoanalytically mediated essays of cultural criticism, this article traces the contour of Liu’s sexual imaginary within the context of 1990s feminist and queer politics. Liu’s modernising project of gender equality, I argue, upholds heterosexual monogamy as a feminist ideal that seeks to purge all the masculine ills, including perversion and promiscuity. Meanwhile, queers and prostitutes come to be figured as the very negativity that must be repressed. Yet, like the Lacanian Real, they impinge on the symbolic order that Liu ordains as they thwart her desire to civilise sex. 相似文献
