In habitually shod recreational runners, we studied the combined influence of footwear and stretch-shortening cycle (SSC) fatigue on treadmill running pattern, paying special attention to neuro-mechanical adjustments in the acute and 2-day delayed recovery periods. The SSC exercise consisted of a series of 25 sub-maximal rebounds on a sledge apparatus repeated until exhaustion. The acute and delayed functional fatigue effects were quantified in a maximal drop jump test. The neuro-mechanical adjustments to fatigue were examined during two submaximal treadmill run tests of 3 min performed either barefoot or with shoes on. Surface electromyographic (EMG) activities, tibial accelerations and kinematics of the right lower limb were recorded during the first and last 15 s of each run. The main result was that neuro-mechanical differences between the shod and barefoot running patterns, classically reported in the absence of fatigue, persisted in the fatigued state. However, in the delayed recovery phase, rearfoot eversion was found to significantly increase in the shod condition. This specific footwear effect is considered as a potential risk factor of overuse injuries in longer runs. Therefore, specific care should be addressed in the delayed recovery phase of SSC fatigue and the use of motion control shoes could be of interest. 相似文献

From the discussion in parts one and two there are two main points that emerge. The first is that it is difficult to identify from outdoor education literature a philosophical framework on which practice is based. Secondly, the body of outdoor education literature attaches more importance to learning outcomes relating to personal and social education than environmental education. The purpose of part three is to offer a philosophical framework and use it to consider the relationship between outdoor education, environmental education and the related concept of sustainability education. The paper starts out by looking at the development of western thought and how it has promoted the concept of epistemological dualism's. The paper then presents an alternative framework of epistemological diversity including experiential, presentational, propositional and practical ways of knowing that has particular relevance for environmental education and sustainability education. Although the prime focus of this paper is environmental education it also deals explicitly with a philosophical framework which includes experiential learning. Consequently, it has relevance to other claims made of outdoor education in particular personal and social education. 相似文献

Previous studies implicate suprasegmental phonology in reading acquisition. However, little is known about how suprasegmental sensitivity develops or how it contributes to reading. Here, 130 Spanish primary-school children participated in this 2-year longitudinal study. Nonlinguistic rhythm, lexical-stress sensitivity and metrical-stress sensitivity, along with phonological awareness, vocabulary, nonverbal intelligence, and reading aloud, were assessed on five occasions. Results suggest that prosody abilities have different developmental trajectories and that prosody explains unique variance in reading beyond that explained by other factors. There was some evidence that the contribution of each prosody skill occurred at different phases in reading development. Nonlinguistic rhythm, lexical-stress sensitivity, and metrical-stress sensitivity assessed at the end of kindergarten, the start of Grade 1, and the end of Grade 1, respectively, predicted reading performance 6 months later. Nevertheless, sample size and reliability temper the conclusions that can be made. The implications of prosody skills for literacy development are discussed. 相似文献

Abstract This paper sets out to discover if the history of outdoor education, within the UK and more particularly Scotland, provides its modern exponents with a legacy of prescribed conservatism or alternatively a form of education which embraces, or is capable of embracing, diversity of theory and practice. It begins in the post World War II period entitled “out of the ashes” and charts the history decade by decade. Secondary sources are used and include statutory instruments as well as the body of literature that relates to outdoor education. The paper has succeeded in adding to the literature through uncovering rarely used sources. Secondary sources have been supplemented by primary data in the form of interviews. The interviews were used to provide detail and fill gaps where secondary sources were lacking. The time between the post-war period until the end of the 1960s charts the growth of outdoor education provision. This growth is characterised by diversity where common themes such as “fitness for war”, “character building” “social education” “recuperative holiday for socially disadvantaged young people” and “progressive education” emerge as competing and contrasting claims. Consequently it can be stated that outdoor education defies definition in terms of being a fixed entity of common consent, homogeneous over time and space. 相似文献

This article applies a capability approach to examine how children's agency, well-being and participation rights can be developed and supported in educational settings. We introduce Amartya Sen's concepts of agency and well-being freedoms and achievements to highlight the tensions and trade-offs between risks to children's agency and well-being in and through educational processes. We draw upon selected empirical examples to illustrate this relationship further. By positioning the development of children's agency as an explicit and important goal of education, alongside well-being achievement, we aim to broaden the evaluative space for assessing what constitutes quality in children's education. We conclude with some reflections on implications for policy and practice going forward. 相似文献

Current interest in promoting physical activity in the school environment necessitates an inexpensive, accurate method of measuring physical activity in such settings. Additionally, it is recognized that physical activity must be of at least moderate intensity in order to yield substantial health benefits. The purpose of the study, therefore, was to determine the validity of the New Lifestyles NL-1000 (New Lifestyles, Inc., Lee's Summit, Missouri, USA) accelerometer for measuring moderate-to-vigorous physical activity in school settings, using the Actigraph GT1M (ActiGraph, Pensacola, Florida, USA) as the criterion. Data were collected during a cross-country run (n = 12), physical education (n = 18), and classroom-based physical activities (n = 42). Significant and meaningful intraclass correlations between methods were found, and NL-1000 estimates of moderate-to-vigorous physical activity were not meaningfully different from GT1M-estimated moderate-to-vigorous physical activity. The NL-1000 therefore shows promising validity evidence as an inexpensive, convenient method of measuring moderate-to-vigorous physical activity in school settings. 相似文献
