The goal of training is to prepare the distance athlete to perform at his or her best during major competitions. Whatever the event, nutrition plays a major role in the achievement of various factors that will see a runner or walker take the starting line in the best possible form. Everyday eating patterns must supply fuel and nutrients needed to optimize their performance during training sessions and to recover quickly afterwards. Carbohydrate and fluid intake before, during, and after a workout may help to reduce fatigue and enhance performance. Recovery eating should also consider issues for adaptation and the immune system that may involve intakes of protein and some micronutrients. Race preparation strategies should include preparation of adequate fuel stores, including carbohydrate loading for prolonged events such as the marathon or 50-km walk. Fluid and carbohydrate intake during races lasting an hour or more should also be considered. Sports foods and supplements of value to distance athletes include sports drinks and liquid meal supplements to allow nutrition goals to be achieved when normal foods are not practical. While caffeine is an ergogenic aid of possible value to distance athletes, most other supplements are of minimal benefit.  相似文献

Soccer players should achieve an energy intake that provides sufficient carbohydrate to fuel the training and competition programme, supplies all nutrient requirements, and allows manipulation of energy or nutrient balance to achieve changes in lean body mass, body fat or growth. Although the traditional culture of soccer has focused on carbohydrate intake for immediate match preparation, top players should adapt their carbohydrate intake on a daily basis to ensure adequate fuel for training and recovery between matches. For players with a mobile playing style, there is sound evidence that dietary programmes that restore and even super-compensate muscle glycogen levels can enhance activity patterns during matches. This will presumably also benefit intensive training, such as twice daily practices. As well as achieving a total intake of carbohydrate commensurate with fuel needs, the everyday diet should promote strategic intake of carbohydrate and protein before and after key training sessions to optimize the adaptations and enhance recovery. The achievement of the ideal physique for soccer is a long-term goal that should be undertaken over successive years, and particularly during the off-season and pre-season. An increase in lean body mass or a decrease in body fat is the product of a targeted training and eating programme. Consultation with a sports nutrition expert can assist soccer players to manipulate energy and nutrient intake to meet such goals. Players should be warned against the accidental or deliberate mismatch of energy intake and energy expenditure, such that energy availability (intake minus the cost of exercise) falls below 125 kJ (30 kcal) per kilogram of fat-free mass per day. Such low energy availability causes disturbances to hormonal, metabolic, and immune function.  相似文献

Research on management in higher education predominantly investigates senior staff such as Deans or Pro-Vice-Chancellors. Relatively little attention is focused on the department level, middle management roles, such as Associate Heads of Schools (AHoS). This case study, based on anecdotal scoping data, utilized a mixed-methods approach through an email survey and face-to-face interview of past and present AHoS at Massey University, New Zealand to investigate participants’ perceptions about the role and the factors that influence it. Results show that a majority of participants did not envisage undertaking higher management within the University after holding the AHoS position, predominantly because the time commitments for the position disadvantaged their teaching and research, and therefore opportunity for academic promotion. Consideration of how AHoS roles may be supported and acknowledging the value of undertaking the role could aid in recognition for promotion and encourage the undertaking of the middle management positions within academia and universities.  相似文献

The last 20 years have brought numerous workforce reforms to the early years sector, enacted in the name of professionalisation, including the recent introduction of a new postgraduate qualification, the Early Years Teacher Status. This article features data from interviews with 22 participants who had just completed this award and situates their views in the relevant policy context and alongside a discussion of what it means to professionalise the early years sector and create a graduate led workforce. The data support findings from similar studies of Early Years Professionals, namely that the interviewees are passionate about working with young children. They view the sector as in need of change, and themselves as potential leaders and agents of change. The participants endorse the view that up-skilling the workforce is essential to the professionalisation of the sector and improving the quality of early years education.  相似文献

How can schools as learning organisations support the realisation of a new curriculum's aspirations? This article describes four common and interrelated challenges—depth, spread, reach, and pace—associated with enacting a new curriculum. It then argues that curriculum capital represented by schools and practitioners that address these challenges and meet associated learning demands—commitment, knowledge, understanding and capability—is essential to ensure that curriculum aspirations are realised. We propose that schools that are learning organisations create the kinds of conditions necessary for responding to the challenges and learning demands. In such schools the considerable individual, collaborative and collective learning needed at many levels is recognised. We highlight how each of the four challenges might be addressed by seven dimensions and four transversals of schools as learning organisations, while recognising that task will be more feasible in systems that are also learning and providing supportive conditions.  相似文献

Drawing upon data gathered from 9301 Year 7 students (12–13 years old) from 46 secondary schools in England, this study represents the first larger-scale attempt to compare their actual set allocations in maths with the counterfactual position where their allocation to sets is based solely on their prior attainment at the end of primary school [using their Key Stage 2 (KS2) fine-grained scores in maths]. Through such an analysis, the study found that nearly a third of students (31.2%) had been misallocated to lower or higher sets than their KS2 results would have warranted. Beyond this, school setting practices were found to exacerbate differences in set allocation in relation to gender and ethnicity, but not socioeconomic background. The odds of girls being misallocated to lower sets in maths than their prior attainment would warrant was found to be 1.5 times higher than that for boys. Similarly, the odds of Black students being misallocated to lower sets was 2.4 times higher than for White students, whilst the odds of Asian students being misallocated to lower maths sets was 1.7 times higher than for White students. The article concludes by reflecting on the significant role that setting by attainment in secondary school can play in exacerbating already established patterns of educational inequalities in gender and ethnicity.  相似文献
