Abstract The aim of this study was to examine the deltoid muscle properties of the dominant and non-dominant arm of Greek professional male tennis players. Eight male tennis players (mean age 22.0 years, s = 3.2) were subjected to biopsy of the deltoid muscle of both arms. Adenosine triphosphate (ATPase) histochemistry and myosin heavy chain (MHC) composition were performed on the samples with homogenate electrophoresis. No significant differences were observed in the percentage of types I, IIa, IIab, and IIb muscle fibres between the deltoid muscles of the two arms. Types I, IIa, and IIx muscle fibres of the dominant and non-dominant deltoid muscles did not differ significantly for MHC isoform composition. Type IIab muscle fibres showed a similar cross-sectional area (CSA) percentage distribution between the two arms. The CSA percentage for types I, IIa, and IIb muscle fibers did not differ significantly between the dominant and the non-dominant arm. We conclude therefore that regular tennis training probably does not lead to any significant changes in the muscle fibre types of the dominant and non-dominant arms of elite tennis players. 相似文献

ABSTRACT— This review examines the effects of military training regimes, which might include some degree of sleep deprivation, on sleep–wake schedules. We report a 4-year longitudinal study of sleep patterns of cadets at the United States Military Academy and the consequences of an extension of sleep from 6 to 8 hr per night at the United States Navy's Recruit Training Command. These studies provide an opportunity to observe sleep in a college-age population and also to record sleep patterns over an entire 4-year college experience, adding to our understanding of the changes in sleep patterns over the life span. 相似文献

This study compared knee angle-specific neuromuscular adaptations after two low-volume isometric leg press complex training programmes performed at different muscle lengths. Fifteen young males were divided into two groups and trained three times per week for 6 weeks. One group (n?=?8) performed 5–7 sets of 3 s maximum isometric leg press exercise, with 4?min recovery, with knee angle at 85°?±?2° (longer muscle-tendon unit length; L-MTU). The other group (n?=?7) performed the same isometric training at a knee angle of 145°?±?2° (180°?=?full extension; shorter muscle-tendon unit length; S-MTU). During the recovery after each set of isometric exercise, participants performed two CMJ every minute, as a form of complex training. Maximum isometric force (MIF) and rate of force development (RFD) were measured over a wide range of knee angles. Countermovement jump (CMJ) performance and maximum half-squat strength (1RM) were also assessed. Training at S-MTU induced a large increase of MIF (22–58%, p?p?p?=?0.001). In contrast, training at L-MTU, resulted in a moderate and similar (≈12.3%, p?=?0.028) improvement of force at all knee angles. CMJ performance and 1RM were equally increased in both groups after training by 10.4%?±?8.3% and 7.8%?±?4.7% (p?相似文献

E-Government projects are currently service oriented, focusing on the implementation and diffusion of digital public services through one-stop points of access for citizens. E-Government strategic plans are political, directed at cost and time minimization during the execution of public services, and they do not take into account citizen needs or public administration operating procedures. Although these plans have led to the development of projects that have succeeded in cost and time savings for both citizens and public administration, surveys conducted around the world show that users evaluate digital public services and do not hesitate to return to traditional methods rather than using digital channels to transact with the public administration again; neither would they recommend the use of digital services to others. This article presents collaborative and participatory tools and methods designed to exploit the knowledge and experience of public servants in the improvement and execution of custom and non-automated public services. Collaborative tools can succeed in the development of real one-stop shops for e-Government, while on the other hand they can encourage both citizens and civil servants to participate in the e-Government era. 相似文献

Purpose: The purpose of this research is to explore the views of young farmers regarding the agricultural training, the training needs and content, as well as the implementation of information technology (IT) and the Internet in agricultural training. The research was conducted in the Greek islands of Cyclades.
Methodology: A quantitative approach was implemented in the research and questionnaires were used for the data collection. There were 129 young farmers (under the age of 40), who participated. These farmers were situated in 23 islands of the Cycladic complex in Greece.
Findings: The research concluded that young farmers in Cyclades were, in general, positively situated towards agricultural training. They also stressed the importance of training content, which focuses on local agricultural needs, instead of tackling general agricultural policies and practices. Consequently, all future training programs should be tailor-made to the needs of local agricultural economies (e.g. different programs for different parts of the country). Although most farmers agreed on the importance of IT technology in the agricultural profession and training, they do not make extensive use of it.
Research Implications: The research shed some light on the basic parameters of the agricultural training parameters. These parameters need to be clearly defined in order to organize future efforts for the modernization of the agricultural profession in Greece. It is believed that the results will help official authorities (e.g. the Ministry of Agricultural Development and Food) to organize future training programs according to the needs of the agricultural population and considering the regional peculiarities in cultivation and stockbreeding.
Originality/Value: A multi-dimensional approach has been followed, by exploring a variety of agricultural training issues: trainees' views, training needs and content and IT use in the agricultural sector and training. The researchers wanted to explore whether their results were similar to those of research that was conducted in the past nationwide, as the Cyclades islands are quite different from the mainland due to geographical reasons. 相似文献

The issue of “predatory” publishing continues to affect many scholars around the world who publish. When one reads the fairly vast literature surrounding “predatory” publishing, there is an erroneous tendency to continue pivoting around Jeffrey Beall's blacklists of “predatory” open access (OA) journals and publishers. However, to be “predatory” involves much more than defining a handful of select behaviours, and it is becoming increasingly important to start defining, or curtailing, the lexicon to avoid referring to any journal or publisher that might display one of the following qualities (exploitative, deceptive, excessive, unscrupulous, abusive, advantageous, manipulative, profit-seeking, or others) as synonymously meaning “predatory”. This paper focuses mainly on the oft-interchangeable terms “predatory” and “exploitation”, and explores the morality of predatory and exploitative actions by applying a deontological ethics approach which implies that certain actions are wrong even if they achieve good consequences, with the understanding that because a predatory entity aims to exploit others, these actions would be considered morally wrong from a deontologist's perspective. In articulating our argument, we attempt to expand the conversation around this important topic, with the hope that it might bring additional clarity to the issue of what might constitute a “predatory” journal or publisher. 相似文献

The management of complex water problems is nowadays being practised through new ways and approaches. Therefore, water engineers, planners and managers should be appropriately educated through modern undergraduate curricula and by well-designed postgraduate specialisation programmes. Within this framework, a study of the specific characteristics of an ensemble of 14 postgraduate programmes in various fields of environmental water resources engineering and management, offered by Greek universities, is presented. Detailed information and data regarding the formats, structures, educational processes and curricula contents of these programmes are analysed and critically discussed. Similarities and differences among them are depicted and synthesised, in order to reveal individual as well as collective qualities and deficiencies in relation with the overall current needs for engineering postgraduate specialisation in water-related issues. 相似文献

The relationship among bodily movements, cognitive abilities, and academic achievement in children is receiving considerable attention in the research community. The embodied learning approach is based on the idea of an inseparable link between body and mind in learning, aiming for teaching methods that promote children’s active engagement in the classroom. This study implements embodied learning as a part of the classroom curriculum in a real classroom environment using motion-based games. A total of 52 elementary students engaged in embodied learning in-class activities for four months. The data-set included standardized pre-post testing for children’s cognitive and academic performance, general learning analytics from games’ usage, interviews, and observations from the teachers involved. Findings showed significant effects both on children’s cognitive abilities (i.e., short-memory skills) and academic performance (i.e., expressive vocabulary). This article contributes to the educational technology community by providing an example of implementing embodied learning via use of motion-based technologies in a real classroom environment. 相似文献

Despite the importance of body donation for medical education and the advancement of medical science, cadaveric donation remains suboptimal worldwide. The purpose of this study was to evaluate the willingness of body donation in Greece and determine the characteristics of donors. This cross‐sectional questionnaire survey was conducted from January to June 2011. A specially designed questionnaire was distributed to 1,700 individuals who were randomly selected from five major Greek cities. It was found that higher educational levels (P = 0.002), annual family income below 30,000 Euros (P = 0.001), guaranteed employment status (P = 0.02), and the presence of comorbid conditions (P = 0.004) seemed to affect potential donors' willingness for cadaveric donation. Those with strong religious beliefs were found to be unwilling to donate their bodies to medical science. Interestingly, the majority of participants who believed that hospitalized patients are deceived or are used for harmful experiments were willing to become whole body donors (P = 0.043). In Greece, the rate of body donation to medical science remains low, and most Greek citizens are not willing to become body donors. Efforts to encourage discussions about whole body donation should be implemented in order to improve current low levels of donation. Anat Sci Educ. © 2012 American Association of Anatomists. 相似文献
