随着研究生规模的逐年增大和高等教育改革的深入,研究生教育中出现了一些不尽如人意的地方,诸如学生的体育意识淡薄、体质下降等,这些现象与新形势下培养全面发展人才的要求很不适应。博士研究生不仅要有渊博的知识和能力,更要具有健康的心理和体魄。参加体育锻炼是促进身心健康的有效手段。但是目前相当一部分博士研究生没有形成良好的体育习惯,不能够坚持体育锻炼。因此了解博士研究生体育态度、分析其影响因素就成为开展研究生体育工作的重要任务之一。  相似文献

Recumbent bicycles (RB) are high performance, human-powered vehicles. In comparison to normal/upright bicycles (NB) the RB may allow individuals to reach higher speeds due to aerodynamic advantages. The purpose of this investigation was to compare the non-aerodynamic factors that may potentially influence the performance of the two bicycles. 3D body centre of mass (BCoM) trajectory, its symmetries, and the components of the total mechanical work necessary to sustain cycling were assessed through 3D kinematics and computer simulations. Data collected at 50, 70, 90 110 rpm during stationary cycling were used to drive musculoskeletal modelling simulation and estimate muscle-tendon length. Results demonstrated that BCoM trajectory, confined in a 15-mm side cube, changed its orientation, maintaining a similar pattern across all cadences in both bicycles. RB displayed a reduced additional mechanical external power (16.1 ± 9.7 W on RB vs. 20.3 ± 8.8 W on NB), a greater symmetry on the progression axis, and no differences in the internal mechanical power compared to NB. Simulated muscle activity revealed small significant differences for only selected muscles. On the RB, quadriceps and gluteus demonstrated greater shortening, while biceps femoris, iliacus, and psoas exhibited greater stretch; however, aerodynamics still remains the principal benefit.  相似文献

Abstract

This study sought to provide empirical evidence concerning physical education information-seeking patterns of elementary teachers at the primary level. It also investigated the relationship between information use patterns and teachers' attributes. A model based on simple utilitarian concepts explaining information use patterns was developed and tested. The basic assumption of the model was that the use of information sources would increase as the perceived benefits of the information derived increased, and the costs of retrieving and using the information decreased. Subjects for the study were elementary school teachers from the Vancouver school system in British Columbia, Canada (N = 86). Simultaneous equation procedures employing limited information likelihood estimators were used to test the model. The results of the study indicated that sources of information internal to the school system dominated utilization patterns. Among these, curriculum support material and discussion with colleagues were highly favored, suggesting that teachers at these grade levels rely heavily upon the experience of others in the same system and the support of very specific resource materials about physical education activities. The research also showed that those who felt they knew more and claimed to enjoy teaching actively sought to acquire more knowledge from more sources than those who knew less. Finally, the study demonstrated that models based on simple assumptions of rationality can predict decisions concerning information utilization.  相似文献
