This study aimed to analyse the effects of a simulated Brazilian jiu-jitsu (BJJ) tournament on vertical jump performance, grip strength test and perceived effort responses. 22 male BJJ athletes participated in a simulated tournament consisting of three 7 min matches separated by 14 min of rest. Kimono grip strength test (KGST), counter movement jump (CMJ) and rate of perceived exertion (RPE) were measured before and after each match, while RPE of specific areas was assessed after three matches. ANOVA for repeated measures was used to compare strength parameters after each match with the level of significance set at 5%. The key results showed a significant decrease of jump height (p = 0.001) and net vertical impulse in the CMJ (p = 0.031), as well as a reduction of the number of reps in the KGST (p < 0.001). A significant increase of RPE was found throughout the matches (p < 0.001). Considering the RPE in specific areas, no differences were observed between the upper and lower body (p = 0.743). We conclude that the BJJ simulated tournament generated a decrease of performance in both upper and lower limbs and provoked a progressive increase in the effort perception over the matches. 相似文献

This study examines the role of regional government quality in health-related participation in sport and physical activity among adults (18–64 years) in 28 European countries. The importance of the analysis rests in the relative autonomy that regional and local governments have over policy decisions connected with sport and physical activity. While existing studies have focussed on economic and infrastructural investment and expenditure, this research investigates the quality of regional governments across 208 regions within 28 European countries. The individual-level data stem from the 2013 Eurobarometer 80.2 (n?=?18,675) and were combined with regional-level data from Eurostat. An individual's level of participation in sport and physical activity was measured by three variables reflecting whether an individual's activity level is below, meets, or exceeds the recommendations of the World Health Organization. The results of multi-level analyses reveal that regional government quality has a significant and positive association with individual participation in sport and physical activity at a level meeting or exceeding the guidelines. The impact is much larger than that of regional gross domestic product per capita, indicating that regional disadvantage in terms of political quality is more relevant than being disadvantaged in terms of economic wealth. 相似文献

The Responsibilities of White Teacher Candidates and Teacher Educators in Developing Racial Literacy
This article aims to help teacher educators consider how to build racial literacy in their White teacher candidates, providing guidance through pedagogical strategies and approaches based on our and others’ research. In addition, much of the pedagogy that we developed in working with our White teacher candidates can be translated to teachers working with White students at other levels, and it can also help teacher educators develop their own racial literacy. 相似文献

This paper reports the findings of a simple normative content analysis of 11 multicultural education textbooks to determine the extent to which disability and deaf culture are represented. In addition, this study examines multicultural education textbooks to assess the extent to which perspectives of members of the disability and deaf communities are represented in the discourse about disabled and deaf persons. Results indicate that on average less than 1% of the total pages of text reviewed addressed or mentioned disability or deaf culture. Of these, it was found that on average about 6% of the pages addressed disability or deaf culture. In addition, inaccurate information was presented and perspectives were often not informed by a substantial body of literature that has emerged in the field of disability studies. It was found that multicultural education textbooks rely heavily on information about persons with disabilities from Special Education that may not be widely accepted by disabled or deaf persons. A follow-up paper examines the implications of the exclusion of disabled and deaf persons and their perspectives from the discourse about the shared and collective disability and deaf experience in favor of a dominant perspective widely held by the nondisabled professional community. Questions are raised about whether this is consistent with the values and goals of multicultural education and teaching. A rationale and recommendations are proposed for engaging disabled and deaf persons about their shared and collective experience and for promoting cultural competence and proficiency with respect to the disability and Deaf experience in multicultural education. 相似文献

The current paper reports on the outcome of an ongoing action research project at a school for higher-functioning students with Autism Spectrum Disorder (ASD) in Sweden. The overall aim of the study was to develop and evaluate a questionnaire that captures social and individual aspects of classroom learning suitable for use with students with ASD. Interview data is presented on the perceived utility of the questionnaire for understanding and planning classroom instruction for the children with ASD through the eyes of the students’ teachers and their parents, as assessed during an Individual Education Plan meeting. Further, teacher ratings obtained by means of the instrument were found to differentiate a group of students with ASD (n = 10) from a group of typically developing children matched with regard to grade year, word reading ability and receptive vocabulary (n = 10). Implications and future directions are discussed, as are limitations of this pilot study. 相似文献

Abstract Since 1947, distance education in Mexico has had an important role for nonconventional populations. Considering that distance education is a heterogeneous and dynamic field, it is important to reflect on the need to improve quality as measured by our own standards. With that perspective in mind, a national meeting was organized to start a self‐diagnosis in which quality and access were the main concerns. Five hundred and twenty specialists from fifty‐one institutions participated in a national interactive synchronous meeting held in four regions. As a result of the meeting, thirty‐five criteria and 230 parameters of quality were established. The main conclusion of the meeting refers to the need for the elaboration of our own indicators for open and distance education. 相似文献

In this paper the authors present a preliminary discussion on some of the results from a survey aimed to explore, describe and explain some of the usability characteristics in digital libraries evaluation in the Mexican context. The study is framed in the evaluation of a multinational and monolingual digital library: the Miguel de Cervantes Virtual Library, from the University of Alicante in Spain. The evaluators were Mexican “expert” users (i.e. Spanish-speaking professional university librarians specialized in electronic reference services) who were asked to carry on an evaluation instrument based on usability criteria as taken from some models in developed countries. Some questions that might be answered with future research are outlined in this paper. 相似文献

The aim of this study was to investigate, for typical shoes and surfaces used in tennis, the relative role of the shoe and
surface in providing cushioning during running. Five test surfaces ranging from concrete to artificial turf were selected,
together with two shoe models. Impact absorbing ability was assessed mechanically using drop test procedures and biomechanically
using peak magnitude and rate of loading of impact force and peak in-shoe pressure data at the lateral heel. Differences in
biomechanical variables between shoe-surface combinations were identified using a two-way ANOVA (p < 0.05). Mechanical test results were found to rank the surfaces in the same order regardless of the shoe model, suggesting
that the surface is influential in providing cushioning. However, for all mechanical and biomechanical (p < 0.05) variables representing impact absorbing ability, it was found that the difference between shoes was markedly greater
than the differences between surfaces. The peak heel pressure data were found to rank the surfaces in the same order as the
mechanical tests, while impact force data were not as sensitive to the changes in surface. Correlations between mechanical
and biomechanical impact absorption highlighted the importance of testing the shoe-surface combination in mechanical tests,
rather than the surface alone. In conclusion, mechanical testing of the shoe-surface combination was found to provide a strong
predictor of the impact absorbing ability during running if pressure data were used. In addition, for typical shoe-surface
combinations in tennis, the shoe was found to have more potential than the surface to influence impact loading during running.
Finally, in-shoe pressure data were found to be more sensitive than force plate data to changes in material cushioning. 相似文献
