Forty-one practitioners inclusive of physiotherapists, sports scientists and strength and conditioning coaches from the academies of elite soccer clubs in the United Kingdom completed an on-line questionnaire which examined their: (1) background information; (2) perceptions of injury occurrence and risk factors; (3) screening and return to play; and (4) approach to designing and delivering injury prevention programmes with a response rate of 55% (41/75). Contact injuries were the most common mechanism reported and players between 13–16 years of age were perceived to be at the greatest risk. Pertinent risk factors included: reduced lower limb and eccentric hamstring strength, proprioception, muscle imbalances, and under developed foundational movement skills. Joint range of motion, jump tests, the functional movement screen, overhead and single leg squats were the most utilised screening methods. Training modalities rated in order of importance included: resistance training, flexibility development, agility, plyometrics and balance training. Training frequency was most commonly once or twice per week, during warm-ups, independent sessions or a combination of both. Injury prevention strategies in this cohort appear to be logical; however, the classification of injury occurrence and application of screening tools to identify “at risk” players do not align with existing research. The frequency and type of training used may also be insufficient to elicit an appropriate stimulus to address pertinent risk factors based on current recommendations.  相似文献

This article shares research facilitated by a multinational technology provider, converging mobile networked technology (tablets) used across school and home, a technology enhanced community ‘third space’ providing workshops for students aged 6–9 with their parents/carers. The approach taken avoids the instrumental measurement of functional digital literacy competences, but instead seeks to negotiate a more nuanced and complex understanding of the ‘uses of literacy’ [from Hoggart, R. 1957. The Uses of Literacy. London: Pelican] in digital contexts and in a deeply situated, specific local setting. Working with our findings, we later put Amartya Sen’s concept of capability [Sen, A. K. 2005. “Human Rights and Capabilities.” Journal of Human Development 6 (2): 151–166; Sen, A. K. 2008. “Capability and Well-Being.” In The Philosophy of Economics, edited by D. M. Hausman, 3rd ed., 270–293. Cambridge: Cambridge University Press] to work on our data in order to provide a discussion on how the digital literacy community might distinguish digital competences as functionings from the ‘uses’ of such competences for a broader range of capabilities.  相似文献

This paper shares an innovative methodology to ‘co-create’ a curriculum with eleven international community development organisations from seven countries to prepare undergraduate students for international work-integrated learning activities. The co-creation process was complex, messy, and always evolving. Here we reflect on and document the process, identifying three key methodological principles that might guide the co-creation process for others. These principles embrace the unpredictable, emotional, and personal reality of bringing together diverse ideas and perspectives, as well as opening up possibilities for more creative ways of communicating and listening to what is seen, heard, and felt.  相似文献

Iron status was surveyed amongst 92 Winter Olympic sport athletes from Nordic and Alpine skiing, figure and speed skating and ice hockey. Haemoglobin and serum ferritin values were obtained by physicians as part of a monitoring programme, since iron deficiency would have an adverse effect on maximal performance. Four (7%) of 56 men were anaemic (Hb < 14.0 gdl‐1) and three (8%) of 36 women had haemoglobin values less than 12.0 gdl‐1. Nine men (16%) and 14 women (39%) had prelatent iron deficiency (serum ferritin < 30 ng ml‐1). Ice hockey had the lowest while Nordic skiing had the highest incidence of sub‐optimal iron status. A total of 50% of Nordic women skiers had prelatent iron deficiency and 7% were anaemic. An equal percentage of women speed skaters were low in serum ferritin as well. Only one of 20 male ice hockey players was low in serum ferritin. These results suggest there would be value in instituting screening procedures for iron status in Winter Olympic Sports.  相似文献

Abstract

The aim of the study was to assess the reliability of a mobile contact mat in measuring a range of stretch–shortening cycle parameters in young adolescents. Additionally, vertical leg stiffness using contact mat data was validated against a criterion method using force–time data. The reliability study involved 18 youths completing a habituation and three separate test sessions, while 20 youths completed a single test session for the validity study. Participants completed three trials of a squat jump, countermovement jump, and maximal hopping test and a single trial of repeated sub-maximal hopping at 2.0 Hz and 2.5 Hz. All tests were performed on the contact mat. Reliability statistics included repeated-measures analysis of variance, intraclass correlation coefficient, and coefficient of variation (CV), while the correlation coefficient (r) and typical error of estimate (TEE) were reported for the validity study. Squat jump height was the most reliable measure (CV = 8.64%), while leg stiffness during sub-maximal hopping, and reactive strength index produced moderate reliability (CV = 10.17–13.93% and 13.98% respectively). Measures of leg stiffness obtained from contact mat data during sub-maximal hopping were in agreement with the criterion measure (r = 0.92–0.95; TEE = 6.5–7.5%), but not during maximal hopping (r = 0.59; TEE = 41.9%). The contact mat was deemed a valid tool for measuring stretch–shortening cycle ability in sub-maximal but not maximal hopping. Although reliability of performance was generally moderate, the tests offer a replicable assessment method for use with paediatric populations.  相似文献

In this paper we consider the effect of moves by the British Government to make initial teacher education (ITE) in England and Wales more school‐based (Blake, 1993). To monitor the impact of this shift towards school‐based training we conducted a fine grain study of what was happening on the ground within the one‐year Secondary School‐Based Postgraduate Certificate in Education (PGCE) at the Chichester Institute of Higher Education (ChIHE). * *At the time the research was conducted, the Institute's name was the West Sussex Institute of Higher Education, hence interviewees refer to ‘WSIHE’ and ‘West Sussex’. View all notes Data were gathered from questionnaire surveys and interviews. Findings from our regional case study indicate that while school‐based ITE programmes may offer student teachers greater insight into school life, this should not be at the expense of developing students’ analytical and theoretical understanding of education and schooling promoted within higher education‐based work.  相似文献

One reason we have difficulty finding sustainable solutions is in part because we are unable to see the bigger picture. Capra (2000 Capra, F. 2000. The challenge of our time.. Resurgence, 203: 1820.  [Google Scholar]) argues, “To become ecologically literate we must learn to think systemically – in terms of connectedness, context and processes” (p. 270). We have attempted to structure connected learning experiences through our transdisciplinary approach to teaching for learning science, mathematics and ecological aspects of society and environment. We support Jucker's (2002 Jucker, R. 2002. Our common illiteracy: Education as if the Earth and people mattered, Frankfurt: Peter Lang.  [Google Scholar]) view that we must have lateral rigor across disciplines and vertical rigor within disciplines in order to best prepare students for teaching. This paper explores the theoretical underpinning of this complex approach to undergraduate teaching and reports on how our teaching team has worked collaboratively to structure a sequence of three, one semester integrated, core courses that explicitly uses an educating for ecological sustainability theme as the basis for each course and associated assessment.  相似文献

Community Level Factors and Child Maltreatment Rates   总被引:8,自引:1,他引:8  
Using census and administrative agency data for 177 urban census tracts, variation in rates of officially reported child maltreatment is found to be related to structural determinants of community social organization: economic and family resources, residential instability, household and age structure, and geographic proximity of neighborhoods to concentrated poverty. Furthermore, child maltreatment rates are found to be intercorrelated with other indicators of the breakdown of community social control and organization. These other indicators are similarly affected by the structural dimensions of neighborhood context. Children who live in neighborhoods that are characterized by poverty, excessive numbers of children per adult resident, population turnover, and the concentration of female-headed families are at highest risk of maltreatment. This analysis suggests that child maltreatment is but one manifestation of community social organization and that its occurrence is related to some of the same underlying macro-social conditions that foster other urban problems.  相似文献
