Nutrition for the young athlete     

Meyer F  O'Connor H  Shirreffs SM;International Association of Athletics Federations 《Journal of sports sciences》2007,25(Z1):S73-S82

Athletics is a popular sport among young people. To maintain health and optimize growth and athletic performance, young athletes need to consume an appropriate diet. Unfortunately, the dietary intake of many young athletes follows population trends rather than public health or sports nutrition recommendations. To optimize performance in some disciplines, young athletes may strive to achieve a lower body weight or body fat content and this may increase their risk for delayed growth and maturation, amenorrhoea, reduced bone density, and eating disorders. Although many of the sports nutrition principles identified for adults are similar to those for young athletes, there are some important differences. These include a higher metabolic cost of locomotion and preferential fat oxidation in young athletes during exercise. Young athletes, particularity children, are at a thermoregulatory disadvantage due to a higher surface area to weight ratio, a slower acclimatization, and lower sweating rate. An appropriate dietary intake rather than use of supplements (except when clinically indicated) is recommended to ensure young athletes participate fully and safely in athletics.  相似文献

Radiant flux through apertures—I     

Parry Moon  Domina Eberle Spencer 《Journal of The Franklin Institute》1978,306(1):1-8

Equations for the calculation of radiant power F through two apertures in series are well known. A characteristic of these formulae is that they give F as a small difference between two large terms. Evidently, the flux through the apertures must decrease as the spacing between them increases; and for large spacing, the inverse-square relation must hold. Instead of exhibiting this behaviour in an obvious manner, however, the traditional equations give the specious impression of an increase in F with increase in spacing. The paper develops an approximate formulae that applies to apertures in the shape of any regular polygon and that shows clearly how the inverse square relation is approached for large separation.  相似文献   

Learning about Interface Design through Peer Assessment     

Helen C. Purchase 《Assessment & Evaluation in Higher Education》2000,25(4):341-352

Peer assessment is recognised as a useful learning activity, not merely as a means by which assignments can be marked. In a design subject such as Human-computer Interaction, peer-assessment offers a unique opportunity for students to be exposed to a wide range of different designs in an environment that ensures that they reflect on these designs. However, it is important that the marking criteria are well specified and unambiguous. This paper reports on the use of peer-assessment as an effective learning activity for revealing the wide range of design issues and dimensions in interface design, where formal marking is based on clear, functional criteria. Subjective consideration of the interfaces is encouraged through a ranking system and the subsequent elicitation of interface design principles. The successful implementation of this scheme demonstrates its benefits both as a learning activity and as an opportunity for student reflection.  相似文献

Physique and performance for track and field events     

O'Connor H  Olds T  Maughan RJ;International Association of Athletics Federations 《Journal of sports sciences》2007,25(Z1):S49-S60

Evidence of the importance of physique in the athletics disciplines is supported by the persistence of certain characteristics over long periods, despite marked secular changes in the source population. These characteristics may also result in physiological benefits such as effective thermoregulation or a greater power-to-weight ratio. Coaches and athletes are often convinced of weight or fat loss benefits based on personal or anecdotal experience, intuition, and "trained eye" observation of successful competitors. This may entice athletes into adopting unbalanced, erratic or highly restrictive eating patterns that increase the risk for nutrient deficiencies, and disordered eating. Despite heavy training loads and often extreme diets, some athletes fall short of their physique goals as ultimately phenotype is under genetic control. Professionals assisting athletes with physique management need to be highly skilled in anthropometry and require a thorough understanding of sports-specific nutrition requirements. Careful assessment of the risks and benefits of various approaches to weight and fat loss is required before they are recommended to athletes.  相似文献   

Assimilation, Faith and Identity: Educational Implications of Change and Continuity     

Helen Johnson 《Pastoral Care in Education》2004,22(3):22-28

In England, the presence of an established church places its adherents within the social mainstream. Other religious groups have been tolerated though suffering social and educational disadvantages. With the passage of time through the nineteenth and twentieth centuries, minority religious groups such as Irish Catholics have been assimilated into the host culture, and allowed to have their own schools.
However, it would appear that contemporary movements of people to the United Kingdom have retained loyalties not only to their own religion, but, in some instances to their own language, which they perceive as a vital element of their own culture and identity. Demands for schools, within the state-funded system, for minority religious groups have not lessened. As faith schools in England increase in number, their role in a multicultural society becomes increasingly problematic. Lessons about changing models of assimilation and identity can be learnt from a brief review of the historic Irish Catholic experience that, in turn, can illuminate the current experience of a Greek Orthodox school in south London.  相似文献
