运动休闲步道管理国际模式研究

随着休闲经济的兴起,运动休闲理念和诸多休闲运动项目也被传播到中国,徒步运动以其健身性、自然性和冒险性的特点,深受世界人民喜爱,今年来已在中国大地慢慢流行开来。与西方国家相比,中国的步道拥有量少得可怜,急需建设大量步道以满足日益增长的徒步爱好者的需求,同时,步道规划、建设、管理成为运动休闲管理的新课题。西方国家的步道管理已有逾百年的经验,其核心要点就是,步道依自然条件而建,尽量突出其自然、野外的特点,尽量减少人工土木的痕迹;在管理上应突出健康性、公益性、环保性的特点;要重视步道建设、管理对运动休闲产业的拉动作用。     

A scale-based approach to interdisciplinary research and expertise in sports

After more than 20 years since the introduction of ecological and dynamical approaches in sports research, their promising opportunity for interdisciplinary research has not been fulfilled yet. The complexity of the research process and the theoretical and empirical difficulties associated with an integrated ecological-dynamical approach have been the major factors hindering the generalisation of interdisciplinary projects in sports sciences. To facilitate this generalisation, we integrate the major concepts from the ecological and dynamical approaches to study behaviour as a multi-scale process. Our integration gravitates around the distinction between functional (ecological) and execution (organic) scales, and their reciprocal intra- and inter-scale constraints. We propose an (epistemological) scale-based definition of constraints that accounts for the concept of synergies as emergent coordinative structures. To illustrate how we can operationalise the notion of multi-scale synergies we use an interdisciplinary model of locomotor pointing. To conclude, we show the value of this approach for interdisciplinary research in sport sciences, as we discuss two examples of task-specific dimensionality reduction techniques in the context of an ongoing project that aims to unveil the determinants of expertise in basketball free throw shooting. These techniques provide relevant empirical evidence to help bootstrap the challenging modelling efforts required in sport sciences.

健身瑜伽对改善中年女性形态和提高柔韧性效应的实验研究

为研究健身瑜伽对女性形体和柔韧性方面的锻炼效果，对62名中年女性进行分组实验，在训练前后对各组进行身体形态和柔韧性指标测试．研究结论：健身瑜伽对腰腹、大腿部的减脂降围有所改善，对形体改善的全面性效应没有健美操明显，但在柔韧性改善方面，健身瑜伽比健美操效果显。
