This study examined the effect of diamond deloading tape on medial gastrocnemius (MG) muscle behaviour during exercise in healthy adults (n = 27). A randomised cross-over trial assessed the effect of tape (no-tape, sham-tape and deload-tape) on ankle and MG fascicle kinematics during three heel raise-lower exercises [double leg (DL), single leg (SL) and loaded single leg (LSL)]. There was no effect of tape on standing fascicle length (FL) or pennation angle (PA), or ankle or knee joint angle. There was a significant effect of tape on ankle kinematics for all exercises. Both the deload-tape and sham-tape resulted in less ankle plantar flexion but had no effect on dorsiflexion. There was a significant effect of tape on FL change for the SL and LSL exercise. Compared to no-tape, the deload-tape resulted in less fascicle shortening during ankle plantar flexion, and more fascicle lengthening during ankle dorsiflexion. For the LSL exercise, deload-tape caused MG fascicles to operate at longer lengths, for a given joint angle. Diamond taping, with or without added tension, has only a small effect on ankle and MG fascicle kinematics during the heel raise-lower exercise. With the exception of the LSL exercise, both tape conditions resulted in similar changes in the FL-angle relations.  相似文献

This is the third in a series of articles exploring international trends in health science librarianship in the first decade of the 21st century. The invited authors were asked to reflect on developments in their country--viz. Austria, Belgium, France and the Netherlands. Future issues will track trends in the Nordic countries, Southern Europe and Latin America. JM.  相似文献

The present study aims at investigating which factors are relevant to induce teachers’ student-centered classroom computer use. Survey data were collected from 361 teachers at comprehensive schools. Based on a systemic view of technology use in schools, different individual teacher characteristics and school contextual factors were examined. Results from a four-step hierarchical regression reveal that student-centered classroom computer use could be significantly predicted by certain contextual factors: the type of school (secondary modern and high school), the existence of an ICT school policy plan, as well as by the individual teacher characteristics of belief in constructivist pedagogy and their frequency of classroom computer use. The final regression model accounted for approximately 31% of the variance in the outcome measure for these factors.  相似文献

Because of the multimodal nature of learning, doing and reporting science, it is important that students learn how to interpret, construct, relate and translate scientific representations or, in other words, to develop representational competence. Explicit instruction about multimodal representations is needed to foster students’ representational competence in the classroom. However, only a handful studies have surveyed how representations are actually used in science classes. This might be because of the fact that economical instruments for assessing the use of representations in classrooms are not available. To bridge that gap, an instrument was developed, field-tested in biology classes with 175 and 931 students, respectively, and analysed using exploratory and (multilevel) confirmatory factor analyses. Results supported an instrument with six scales and 21 items at the individual and classroom levels covering the following dimensions: (1) interpretation of visual representations, (2) construction of visual representations, (3) use of scientific texts (verbal representations), (4) use of symbolic representations, (5) number of terms used in class, and (6) the extent to which active social construction of knowledge is possible in the class. The scales showed satisfactory discriminant validity and reliability at each level. Further applications of this instrument for researchers and teachers are discussed.  相似文献

There is no consensus as to whether, and if so, in which regard and to what extent science and religion is needed for human survival. Here a circumscribed domain is taken up: the sovereignty and sufficiency of the human brain in this context. Several of its shortcomings are pointed out. Religion and other aspects of culture are needed for remedial action. To determine such an action, a broad-based dialogue is required, based on the most promising ontology and epistemology as well as on appropriate logics.  相似文献
