It is believed that sport massage after intensive exercise might improve power and perceptual recovery in athletes. However, few studies have been done in this area. This study aimed to examine the effect of massage on the performance of bodybuilders. Thirty experienced male bodybuilders were randomly assigned to either a massage group (n = 15) or a control group (n = 15). Both groups performed five repetition sets at 75–77% of 1RM of knee extensor and flexor muscle groups. The massage group then received a 30-min massage after the exercise protocol while the control group maintained their normal passive recovery. Criteria under investigation included: plasma creatine kinase (CK) level, agility test, vertical jump test, isometric torque test, and perception of soreness. All variables were measured over 6 time periods: baseline, immediately after the DOMS inducing protocol, right after the massage, and 24, 48, and 72 h after the massage. Both groups showed significant (P < .001) decreases in jumping, agility performance, and isometric torque, but significant (P < .001) increases in CK and muscle soreness levels. The massage group in general demonstrated a better recovery rate. As such, a post-exercise massage session can improve the exercise performance and recovery rate in male bodybuilders after intensive exercise.  相似文献   

How is the ethical dissonance index affected by technology,academic dishonesty type and individual differences?     

Yael Sidi  Ina Blau  Yoram Eshet-Alkalai 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(6):3300-3314

Academic dishonesty has been growing in both digital and analog settings. The present study aimed to generalize the ethical dissonance index (EDI), which was established in a sample of Israeli school students as the gap between the pervasiveness of academic dishonesty and its perceived legitimacy. Furthermore, the study examined how technology, dishonesty type and individual differences affect these factors. The study employed a scenario-based approach – an indirect strategy for deducing academic dishonest behaviors. Participants were 1055 school students from various grade levels, geographic locations and religious/ethnic sectors. Results regarding the role of technology revealed that, overall, digital academic dishonesty was less pervasive and deemed more legitimate compared to analog dishonesty. However, this relationship varied as a function of dishonesty type. Findings confirmed that students experienced some level of ethical dissonance, generalizing the EDI. Notably, individual differences did not affect the relationship between media, dishonesty type and the EDI.  相似文献   

Open feedback in gymnastic judging causes conformity bias based on informational influencing     

Boen F  van Hoye K  Auweele YV  Feys J  Smits T 《Journal of sports sciences》2008,26(6):621-628

The aims of this study were twofold: (1) to determine whether open feedback (i.e. the ability to hear or see the scores of colleague judges after each performance) would lead judges in gymnastics to conform with their colleagues, and (2) to identify the underlying process on which this conformity is based. Twenty-three certified Flemish judges in women's gymnastics were randomly divided into panels of a maximum of five judges. These panels had to rate the same 30 videotaped individual vaults: 15 in phase 1 and 15 in phase 2. Two independent variables were orthogonally manipulated: feedback (or no feedback) during phase 1 and feedback (or no feedback) during phase 2. The results of phase 1 revealed that the variation between the judges' scores was less within panels that had received feedback than within panels that had not received feedback. We therefore conclude that the availability of feedback elicits conformity among gymnastic judges. The results of phase 2 indicated that this conformity continued even when feedback was no longer provided, suggesting that the observed conformity was based on informational influencing (i.e. because of uncertainty about the correct responses) and not on normative influencing (i.e. out of fear of standing out in the group).  相似文献   

PROSPECTIVE MEMORY TRAINING IN OLDER ADULTS     

Iris W. Schmidt  Ina J. Berg  Betto G. Deelman 《Educational gerontology》2013,39(6):455-478

This study evaluates the results of a training program for prospective remembering. The goal of the training was to improve prospective memory by associating cues from the retrieval situation with the to be remembered information. The training group consisted of 20 participants, aged between 45 and 81 years. The effects of strategy training were compared with those of an educational training group (N = 23 , age range 45-84) directed at reducing worries about forgetfulness, and a retest control group (N = 22 , age range 46-74). The educational training and retest control groups did not differ in demographic characteristics and test performance and were combined into one control group. Subjective evaluations revealed that subjects were very satisfied with the effects of training. This also was true for subjects in the educational training condition. The objective effects of training were evaluated with a telephone task which had to be performed in the daily life situation, and a prospective categorization task performed in the laboratory. Despite the low reliabilities of the prospective tasks, a significant but small effect of training compared to the combined control group was found on the sum score of prospective tests. The training effect was not related to age or pretraining performance level. At the three months follow-up, however, performance of the control group had increased to the level of the trained group. As expected, training effects did not generalize to other memory measures (assessed with tests for remembering names) or control measures (assessed with visuo-motor reaction time tests).  相似文献   

Museum Assessment and FDH Technology: Towards a Global Approach     

François Mairesse  Philippe Vanden Eeckaut 《Journal of Cultural Economics》2002,26(4):261-286

This paper presents a global approach for museum assessment. We conceptualise a museum as an entity which needs to be evaluated according to three well defined tasks: preservation, research and communication, and outcomes. We propose a methodology based on the determination of efficiency frontiers. This method uses a deterministic non parametric and non convex technology (Free Disposal Hull). We analyse technical efficiency, but also scale efficiency with a new restrictive scale approach. We present an ordering of museums into classes representing a level of performance with respect to the three required tasks. We illustrate our analysis using a three year database of museums from the French speaking region of Belgium.  相似文献

Factors predictive of black students' communication with the administration and students at a predominantly white university     

Warren Watson  Ina Siler 《Int J Intercult Relat》1984,8(3):255-267

Black students' interaction with a predominantly white university's administration, faculty, and students appears to be a central issue in current study of black student success in college. This study examined personality and situational factors predictive of black students' communication with such a university's administration, faculty, and students. The development of an instrument describing environmental and social concerns of black students demonstrated reasonable predictive validity of communication with the administration and white students. Feelings about the social environment and tendencies of communication anxiety were among the strongest predictors of black students' communication.  相似文献   

The Delphi Project: Transforming Flemish Libraries Into User-Oriented Points of Information     

Patrick Vanden Berghe 《Journal of Web Librarianship》2016,10(4):316-326

ABSTRACT

Flemish libraries have historically been praised by visitors and valued by the general public, but since the turn of the century, they have seen a decline in usage. A group of libraries in Flanders believed the role of libraries should be substantially reevaluated. They embarked on the “Delphi Project” to establish methods for libraries to become centers of their local communities by focusing on the information needs of their customers. The emergence of technology supported a shift from libraries as lending institutions to information centers. In addition to a customer service philosophy and training, online tools have helped staff reach library users. An online tool called the “Bronnenwijizer” combines searching the local library catalogue, provincial and state catalogues, and the Internet. The tool also supports the creation of “baskets” for a patron's information needs that can be shared with other staff. Delphi libraries have also used “Infopleinen,” Web-based guides to topics featuring printed media and online sources. Finally, a new online question registration system was developed that fit the new Delphi service philosophy. Over half the libraries in West-Vlaanderen are entitled to call themselves Delphi Libraries, and the philosophy is being disseminated more broadly through the Delphi Project Web site. Due to governmental changes in provincial authority, the future of the project is challenged because coordination among libraries has been critical for the project's success.  相似文献   

“I experienced freedom within the frame of my own narrative”: The contribution of psychodrama techniques to experiential learning in teacher training     

Ina ter Avest 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2017,63(1):71-86

To prepare Dutch students in education for critical situations in their professional life as a teacher, part of their training is to ask them to reflect upon their own experiences in their life as a child, a pupil and a student – experiences of crucial moments or with significant others which are still of the utmost importance to them. This article underlines the significance of so-called “experiential learning” in student career counselling. In this context, experiential learning is understood as an extension of in-depth reflection on critical incidents and critical persons in the biography of pre-service teachers. This reflection – customary and effective in Dutch teacher training – is a verbal process. However, this technique does not seem to be adequate for many students from other cultural backgrounds (e.g. second-generation descendants of migrant workers). By consequence, some of these students are not able to take newly offered information on board, but remain imprisoned in their own culture-related narrative, their own ethnic society of mind. Research has shown that for these students, psychodrama techniques, focusing on non-verbal and playful aspects of reflection, seem to be more suitable. The author of this article presents a sample case from a pilot study which used one of the psychodrama techniques called the empty chair. The findings of the pilot study are promising in the sense that experiencing different I-positions does seem to help students from other cultural backgrounds to develop agency in responding to hitherto unfamiliar and confusing situations.  相似文献
