ABSTRACT The aims of the present study were to provide an in-depth comparison of inter-limb asymmetry and determine how consistently asymmetry favours the same limb during different vertical jump tests. Eighteen elite female under-17 soccer players conducted unilateral squat jumps (SJ), countermovement jumps (CMJ) and drop jumps (DJ) on a portable force platform, with jump height, peak force, concentric impulse and peak power as common metrics across tests. For the magnitude of asymmetry, concentric impulse was significantly greater during the SJ test compared to CMJ (p = 0.019) and DJ (p = 0.003). No other significant differences in magnitude were present. For the direction of asymmetry, Kappa coefficients revealed fair to substantial levels of agreement between the SJ and CMJ (Kappa = 0.35 to 0.61) tests, but only slight to fair levels of agreement between the SJ and DJ (Kappa = ?0.26 to 0.18) and CMJ and DJ (Kappa = ?0.13 to 0.26) tests. These results highlight that the mean asymmetry value may be a poor indicator of true variability of between-limb differences in healthy athletes. The direction of asymmetry may provide a useful monitoring tool for practitioners in healthy athletes, when no obvious between-limb deficit exists. 相似文献

Lifelong learning remains a powerful and valid concept important for the evolution of higher education and the university in the changing context of globalization, 30 years after its first popularization around 1970. Like the related concept of the learning society, it suffers trivializing fashion and reductionism. As we move into a phase of universal tertiary education, it is all the more necessary to understand how to enable universities to become learning organizations playing a distinct role in a fast-changing world. Enterprise is an essential associated characteristic, rather than a betrayal of the essentially academic. Universities need to function as open systems, building partnerships and sharing networks in and beyond their localities, and playing leading roles in the creation of learning regions and in new modes of knowledge protection. A grasp of these issues points the way for universities to survive as valued and unique social institutions adapted to and playing an active part in the making of knowledge societies. 相似文献

For this talk, Marks was tasked with summarizing the important trends in scholarly publishing in 45 minutes. The speaker reflected on the rapid changes that have occurred in journal publishing, which followed more than 300 years of relatively slow progress. Marks discussed key technology trends such as data curation, Open Access (OA) mandates, and the changes occurring in the global landscape of scholarly communications and library budgets. Wolters Kluwer Health has been responding to these trends with new publishing experiments including a Platinum OA model in emerging markets. Marks discussed the ways that publishers and libraries need to alter their traditional practices and instill a focus on their customers and communities. 相似文献
