In this study, we evaluated the peak torque, functional torque ratios, and torque curve profile of the shoulder rotators in overhead athletes with impingement symptoms so as to examine possible alterations in response to sports training and shoulder pain. Twenty-one overhead athletes with impingement symptoms were compared with 25 overhead athletes and 21 non-athletes, none of whom were symptomatic for impingement. The participants performed five maximal isokinetic concentric and eccentric contractions of medial and lateral shoulder rotations at 1.57 rad · s(-1) and 3.14 rad · s(-1). Isokinetic peak torque was used to calculate the eccentric lateral rotation-to-concentric medial rotation and the eccentric medial rotation-to-concentric lateral rotation ratios. An analysis of the torque curve profiles was also carried out. The eccentric lateral rotation-to-concentric medial rotation torque ratio of asymptomatic athletes was lower than that of non-athletes at both test velocities. The concentric medial rotation isokinetic peak torque of the asymptomatic athletes, at 3.14 rad · s(-1), was greater than that of the non-athletes, and the peak appeared to occur earlier in the movement for athletes than non-athletes. These findings suggest that there may be adaptations to shoulder function in response to throwing practice. The eccentric medial rotation-to-concentric lateral rotation torque ratio was altered neither by the practice of university-level overhead sports nor impingement symptoms. 相似文献

This article explores how elitist elements are preserved within an expanding higher education. It analyzes whether the choice of field of study may be one of these elements and focuses on the case of Roma students in Eastern and Southeastern Europe. The analysis reveals that Roma in the region are not only underrepresented in higher education in general, but also in the STEM fields of study (science, technology, engineering, mathematics). At the same time, Roma are overrepresented in humanities and arts. This has the potential to negatively impact their competitiveness in the job market upon graduation. 相似文献

The FCC's proposal for Universal Service Fund (USF) reform proposes to replace current universal service funding programs with the Connect America Fund (CAF), a fund devoted to using government support to make broadband service available in un-served or under-served geographical locations. The goal is to maximize the bang-per-buck from available funds by looking at incremental upgrades to existing infrastructure in under-served areas and incremental infrastructure build-outs in un-served areas. The strategy is to encourage competition between broadband providers whether they are wireless providers or wireline providers. 相似文献

In this paper, we present an analysis of the Scholarship of Teaching and Learning in Higher Education (SoTL) which contributes to SoTL both as a field of research practice and as a background to professional development in higher education. We analyse and describe the constitution of the field, and in so doing address its nature in the face of the dilemma of, on the one hand, its diversity and, on the other hand, its generally agreed set of purposes. Our analysis of SoTL knowledge is conceptualised as relational, connecting SoTL practitioners with the work they disseminate to the community at large. We describe and exemplify the internal horizon of the field in terms of five domains: the didactic and the epistemic, which we refer to as the knowledge building domains, and the interpersonal, the moral/ethical and the societal domains, which we refer to as the axiological domains. The external horizon is described in terms of four aspects of the context that can impact the production and implementation of SoTL knowledge: the disciplinary, the professional, the cultural and the political aspects. Methodological emphasis is equally on the axiological underpinnings of SoTL, its values and attitudes, as the ontological and epistemological underpinnings that are predominant. 相似文献
