The relationship among motor proficiency, physical fitness, and body composition in children with and without visual impairments     

Houwen S  Hartman E  Visscher C 《Research quarterly for exercise and sport》2010,81(3):290-299

This study compares the motor skills and physical fitness of school-age children (6-12 years) with visual impairments (VI; n = 60) and sighted children (n = 60). The relationships between the performance parameters and the children's body composition are investigated as well as the role of the severity of the impairment. The degree of VI did not differentially affect the outcomes. Compared to their sighted peers, the children with VI scored lower on the locomotor and object control skills as assessed with the Test of Gross Motor Development-2, and the physical fitness (Eurofit) parameters of plate tapping, the standing broad jump, the modified 5 x 10-m shuttle run, and 20-m multistage shuttle run (20-MST). Their body mass and body fat indexes were inversely correlated with the standing broad jump and the 20-MST but positively correlated with handgrip strength. Moreover significant inverse correlations were found between their locomotor and object control skills on the one hand and plate tapping and the 5 x 10-m shuttle run on the other hand. Given the relatively high proportion (25%) of overweight/obese children within the VI sample, educators are recommended to promote health-related activities and help enhance motor skills in this population.  相似文献   

Multidimensional performance characteristics and standard of performance in talented youth field hockey players: a longitudinal study     

Elferink-Gemser MT  Visscher C  Lemmink KA  Mulder T 《Journal of sports sciences》2007,25(4):481-489

To identify performance characteristics that could help predict future elite field hockey players, we measured the anthropometric, physiological, technical, tactical, and psychological characteristics of 30 elite and 35 sub-elite youth players at the end of three consecutive seasons. The mean age of the players at the end of the first season was 14.2 years (s = 1.1). Repeated-measures analyses of covariance, with standard of performance and measurement occasion as factors and age as a covariate, showed that the elite players fared better than the sub-elite players on technical and tactical variables. Female elite youth players also scored better on interval endurance capacity, motivation, and confidence. Future elite players appear to have excellent tactical skills by the age of 14. They also have good specific technical skills and develop these together with interval endurance capacity better than sub-elite youth players in the subsequent 2 years. To verify our conclusions, we will be tracking these players into adulthood.  相似文献   

Are We Ready to Recommend a College Readiness Index? A Reply to Gaertner and McClarty (2015)     

Rory A. Lazowski  Kenneth E. Barron  Jeff J. Kosovich  Chris S. Hulleman 《Educational Measurement》2016,35(3):26-29

In an article published in Educational Measurement: Issues and Practice, Gaertner and McClarty (2015) discuss a college readiness index based, in part, on nonacademic or noncognitive factors measured in middle school. Such an index is laudable as it incorporates important constructs beyond academic achievement measures that may be important in assessing college readiness. It also holds potential in identifying areas of need at a critical time and can theoretically inform important interventions that may be necessary prior to the later stages of high school. However, one of the noncognitive factors—motivation—appeared to be theoretically incomplete, underrepresented, and contained items irrelevant to the construct of academic motivation. We offer our concerns about the validity of this factor as measured by the index and the associated implications about the consequences of using this to inform educational interventions. Through this commentary, we hope to offer constructive feedback on future research that can build upon Gaertner and McClarty's important work.  相似文献

Priming institutional change through effective project management:A case study of the Chic project     

Richard Hall  Derek Harding  Chris Ramsden 《International Journal for Academic Development》2013,18(2):152-161

This paper explores how learning and teaching innovations undertaken by externally funded projects, with a fixed remit and lifecycle, can be integrated successfully into institutional educational developments. The example and methods of one particular project, in embedding its work within and relating it to the context of wider, nationally-promoted educational designs, is utilized to illustrate the possibilities for fostering institutional change. Such change relies upon working to promote a climate whose norms support a culture of trust, where team-working can forge a broader ownership of innovation  相似文献   

Free the sheep: improvised song and performance in and around a minecraft community     

Chris Bailey 《Literacy》2016,50(2):62-71

Recent work around the use of virtual world video games in educational contexts has conceptualised literacies as communal processes, whilst considering complex notions of collaboration through participants' multiplicity of presence in hybrid virtual / physical locations. However, further research is necessary in order to help us understand how the complex interactions afforded by such spaces influence ‐ and are influenced by ‐ children's social relationships. This article draws upon data from a year‐long ethnographic study, investigating a group of ten and eleven year old children's engagement with the video game ‘Minecraft’ as they collaborate to build a ‘virtual community’. With a particular focus on the children's improvised singing and use of song during the club, I examine how their creative practices ‐ drawing on a wide range of self‐selected resources, played out both in and out of the virtual world ‐ help to fundamentally shape the nature of the space around them. Furthermore, through examination of one particular performance, I demonstrate the importance of ensuring that such details are not written out of accounts of children interactions around technology, if we are to understand the true potential of such environments.  相似文献

Test-retest reliability of a battery of field-based health-related fitness measures for adolescents   总被引：2，自引：2，他引：0  

Lubans DR  Morgan P  Callister R  Plotnikoff RC  Eather N  Riley N  Smith CJ 《Journal of sports sciences》2011,29(7):685-693

The main aim of this study was to determine the test-retest reliability of existing tests of health-related fitness. Participants (mean age 14.8 years, s?=?0.4) were 42 boys and 26 girls who completed the study assessments on two occasions separated by one week. The following tests were conducted: bioelectrical impedance analysis (BIA) to calculate percent body fat, leg dynamometer, 90° push-up, 7-stage sit-up, and wall squat tests. Intra-class correlation (ICC), paired samples t-tests, and typical error expressed as a coefficient of variation were calculated. The mean percent body fat intra-class correlation coefficient was similar for boys (ICC?=?0.95) and girls (ICC?=?0.93), but the mean coefficient of variation was considerably higher for boys than girls (22.2% vs. 12.2%). The boys' coefficients of variation for the tests of muscular fitness ranged from 9.0% for the leg dynamometer test to 26.5% for the timed wall squat test. The girls' coefficients of variation ranged from 17.1% for the sit-up test to 21.4% for the push-up test. Although the BIA machine produced reliable estimates of percent body fat, the tests of muscular fitness resulted in high systematic error, suggesting that these measures may require an extensive familiarization phase before the results can be considered reliable.  相似文献   

A 12-week Interdisciplinary Intervention Program for Children who are Obese     

James W Farris  Laura Taylor  Megan Williamson  Chris Robinson 《Cardiopulmonary Physical Therapy Journal》2011,22(4):12-20

Childhood obesity is a growing problem, for which multi-disciplinary interventions are needed. Purpose: This interdisciplinary intervention program was designed to improve the health of children who were obese. Methods: Twenty-five children, mean age 8.1 (1.5) years; body mass index (BMI)> 98^th percentile, and their parents completed the 12-week (3 days/wk) intervention consisting of aerobic and resistance exercise appropriate to age and developmental levels. Baseline and posttest measures of blood values, fitness, and cardiovascular risk factors were performed. Data were analyzed using paired t-tests with significance accepted at P ≤ .05. Results: Significant differences between means (SD) for pre- and post-measurements were, respectively: BMI 30.31 (4.56), 27.80 (4.54), body-fat percent 43.7 (11.5), 40.7 (10.9), waist circumference 82.1 (7.1), 80.4(6.1) cm, calf circumference 34.2 (3.1), 35.2 (3.1) cm; step-test heart rate 137 (20), 126 (12) bpm, push-ups 1.0 (1.8), 5.6 (3.8), sit-ups 23.6 (12.7), 33.2 (13.8), sit-and-reach 35.1 (7.4), 41.2 (5.8) cm; systolic BP 102 (10), 108 (9) mmHg, glucose 4.9(0.3), 4.8 (0.4) mmol/L, total cholesterol 4.6 (1.0), 4.2 (0.8) mmol/L, ALT 41 (9), 35 (8) U/L, bilirubin 6.3 (2.4), 5.6 (2.1) μmol/L, and BUN 4.9 (1.1), 4.3 (0.9) mmol/L. Conclusions: This interdisciplinary intervention program positively affected the fitness and health status of children who were obese by involving the children and parents.Key Words: childhood obesity, cardiovascular risk factors, health, fitness  相似文献   

Truth and opinion in climate change discourse: the Gore-Hansen disagreement     

Russill C 《Public understanding of science (Bristol, England)》2011,20(6):796-809

In this paper, I discuss the "inconvenient truth" strategy of Al Gore. I argue that Gore's notion of truth upholds a conception of science and policy that narrows our understanding of climate change discourse. In one notable exchange, Gore and NASA scientist, James Hansen, disagreed about whether scientific statements based on Hansen's computer simulations were truth or opinion. This exchange is featured in An Inconvenient Truth, yet the disagreement is edited from the film and presented simply as an instance of Hansen speaking "inconvenient truth". In this article, I compare the filmic representation of Hansen's testimony with the congressional record. I place their exchange in a broader historical perspective on climate change disputation in order to discuss the implications of Gore's perspective on truth.  相似文献
