The aims of this study were to describe muscular activation patterns and kinematic variables during the complete stroke cycle (SC) and the different phases of breaststroke swimming at submaximal and maximal efforts. Surface electromyography (sEMG) was collected from eight muscles in nine elite swimmers; five females (age 20.3 ± 5.4 years; Fédération Internationale de Natation [FINA] points 815 ± 160) and four males (27.7 ± 7.1 years; FINA points 879 ± 151). Underwater cameras were used for 3D kinematic analysis with automatic motion tracking. The participants swam 25 m of breaststroke at 60%, 80% and 100% effort and each SC was divided into three phases: knee extension, knee extended and knee flexion. With increasing effort, the swimmers decreased their SC distance and increased their velocity and stroke rate. A decrease during the different phases was found for duration during knee extended and knee flexion, distance during knee extended and knee angle at the beginning of knee extension with increasing effort. Velocity increased for all phases. The mean activation pattern remained similar across the different effort levels, but the muscles showed longer activation periods relative to the SC and increased integrated sEMG (except trapezius) with increasing effort. The muscle activation patterns, muscular participation and kinematics assessed in this study with elite breaststroke swimmers contribute to a better understanding of the stroke and what occurs at different effort levels. This could be used as a reference for optimising breaststroke training to improve performance. 相似文献

The article is a discussion and an analysis of an event observed in a critical classroom study on teaching and learning in physical education. It demonstrates how sociocultural discourses are embedded in children's and teachers' discursive practices [Fairclough (1992) Discourse and Social Change (Cambridge, Polity Press)] in the classroom, how discourses of physical education and discourses of gender relations are connected, and how these construct and are constructed by the social structures of the physical education lesson, and influence students' learning. Using the notion of situated learning [Lave & Wenger (1991) Situated Learning: Legitimate Peripheral Participation (Cambridge, Cambridge University Press); Wenger (1998) Community of Practice: Learning, Meaning, and Identity (Cambridge, Cambridge University Press)], the paper analyses how discourses in the physical education setting influence children's learning processes, and points to the different meanings the discursive practices observed in the classroom have for the girls as compared to the boys. This analysis allows for some concluding comments on learning and the hidden curriculum in physical education. 相似文献

德国高校层次结构分析 总被引：1，自引：0，他引：1
德国院校的结构"纵向分三层,横向分若干类",近年却呈现"四圈层"的特点。德国高校在层次结构、高校设置、成人教育、科研与教学等四个方面所具有的特点,在稳定高等教育系统、规范高校设置、就业制度与高校层次、全日制教育与业余教育关系和高校层次划分等方面的做法,都有可供中国借鉴之处。 相似文献
