This study aimed to investigate the independent and combined associations between several fatness indicators and fitness components with functional movement quality in overweight/obese children. A total of 56 children (33 girls, aged 8–12) classified as overweight/obese according to the World Obesity Federation standard cut points, participated in this study. Participants underwent assessments of fatness [body mass index (BMI), waist circumference, and bioelectrical impedance measures], fitness [1 repetition maximum bench and leg press, and ALPHA test battery], and functional movement quality [4 tests from Functional Movement Screen TM (FMS)]. All fatness outcomes, except waist circumference, were negatively associated with total FMS score, after controlling for cardiorespiratory fitness. Cardiorespiratory fitness, lower limbs muscle strength, and speed-agility were positively associated with the total FMS score, regardless of BMI. Our results suggest that children with greater fatness indicators demonstrate lower functional movement quality independently of their fitness level, whereas children with better fitness level (i.e. cardiorespiratory fitness, lower limbs muscular strength, and speed-agility) demonstrate greater functional movement quality independently of their fatness level. However, children´s weight status seems to be more determinant than their fitness level in terms of functional movement quality, whereas being fit seems to moderately attenuate the negative influence of fatness. 相似文献

Background: Flamenco is a highly emotional and demanding dance form. It is important to understand how the dancer’s body works in order to improve fitness levels and reduce injuries. Thus, our investigation reviewed studies on kinesiological aspects of flamenco over recent years. Methods: The review was restricted to experimental studies. Literature searches were conducted using the following databases: PubMed, Scopus, and Ebsco: SPORTDiscus with Full Text, Medline, Health Source: Nursing/Academic Edition, Health Source – Consumer Edition. After limiting the search, 180 potential articles remained for analysis. Results: A total of 27 papers on different aspects of flamenco dance were finally selected: biomechanics (14), podiatry (6), injury incidence (3), anthropometry (2), and physiology (2). These studies have applied well-established methods from sports studies. However, we noted a number of potential limitations when applied to flamenco. Conclusions: The evidence from this review shows that flamenco dancing demands high levels of effort. Further research is required to understand how the dancer’s body works in order to improve fitness levels and reduce injuries. Most of the results presented here are consistent among studies. However, there is a great scarcity of research addressing flamenco movement in a more comprehensive perspective. 相似文献

The procedures for making and applying a new family of high viscosity aqueous polymeric dispersions based on poly(vinyl alcohol)-borax (PVA-borax) matrices are presented. A specific system of this type has been used to remove an oxidized varnish coating from the surface of “Coronation of the Virgin with Saints”, a 15th century egg tempera painting on wood by Neri di Bicci (Florence, 1418–1492). FTIR spectra showed that the oxidized varnish was constituted of highly aged shellac resin. Good cleaning performance was attained when the liquid portion of the dispersion consisted of a mixture of water and acetone. Rheological investigations indicate that the acetone content does not affect the mechanical properties of the polymeric dispersion. Those mechanical properties permit easy removal of the cleaning agent simply by peeling it from the surface by means of a forceps or spatula once it has carried out its cleaning function. Optical microscopic and FTIR investigations show that the cleaning agent is able to remove the oxidized varnish coating from the surface of the Neri di Bicci painting without leaving detectable residues. 相似文献

This articie is a brief response to an article on spelling by David Waugh which appeared in Vol. 29(2). The authors argue that the Letterland system can be of great benefit in approaching spelling. 相似文献

The article discusses two instant measures of affective value of information objects: Willingness-to-Pay (WTP) and Experienced Utility (EU). The potential utility of these measures for information retrieval research is positioned within a broader discussion of distinctions between instant utility and remembered utility and their relationship to immediate as opposed to retrospective subjective evaluations. The paper describes an approach for obtaining instant WTP and EU ratings in document evaluation in contexts of information search and thereafter reports results from a usability study of its implementation. Participants encountered no difficulties in use of the design format and in rating documents using WTP and EU measures. Although two measures were found statistically significantly correlated with each other, participants in the usability study offered different reasons for the ratings of WTP and EU made for the same document. 相似文献

Increasingly, student outcomes assessment is being viewed as a component of comprehensive academic program review. The Hong Kong peer review process is typical of program review in the United Kingdom and Europe. In the second article in this issue, Ruth Green describes a typical U.S. program review process. —Editor. 相似文献

This article considers models involving a single structural equation with latent explanatory and/or latent dependent variables where discrete items are used to measure the latent variables. Our primary focus is the use of scores as proxies for the latent variables and carrying out ordinary least squares (OLS) regression on such scores to estimate parameters in the structural equation. We are concerned with the bias in these OLS estimates; we present two approaches to deal with this bias. Extending the work of Skrondal and Laake (2001) on continuous items, we derive sufficient conditions under which the use of scores based on item response theory leads to unbiased OLS estimates at the population level; we deem this approach “bias avoiding.” We also consider Croon's (2002) bias correction methodology for continuous items and explore its efficacy on discrete items; we deem this approach “bias correcting.” We illustrate the performance of the 2 approaches through numerical examples of large simulated data sets. 相似文献

Critical thinking is a unifying goal of modern education. While past research has mostly examined the efficacy of a single instructional approach to teaching critical thinking, recent literature has begun discussing mixed teaching approaches. The present study examines three modes of instruction, featuring the direct instruction approach and the inquiry-based approach in different sequences and proportions, in enhancing Chinese secondary student’s critical thinking performance. A total of 651 Grade 12 students participated in an 18-hour intervention with pre- and post-intervention measures on critical thinking performance and critical thinking dispositions. Specifically, critical thinking assessments utilizing different response format were used. Those who received training showed greater improvement on at least one of the critical thinking assessments compared to those who received no training. Participants’ performances with regards to different critical thinking assessments are discussed. Benefits of adopting more than one instructional approach to teaching critical thinking are highlighted. 相似文献
