房陵文化汇聚在医药里,浸泡在药酒里,流淌在山歌中,浓缩在婚丧嫁娶的习俗里。房陵这块古老神奇的土壤是周莹散文创作的源泉,喝着房陵文化乳汁成长的房陵忠诚女儿周莹,用《指尖上跳跃的青春》这首歌,歌唱着她对这块土地最深沉最朴实的爱。《指尖上跳跃的青春》生动再现地是房陵人日常生活与情感的画卷,是房陵文化的符号。 相似文献

Basic motor skills development is achieved through the implementation of different types of physical education programs. The purpose of this study was to investigate and to compare the effect of a developmentally appropriate music and movement program and of a developmentally appropriate physical education program on the development of jumping and dynamic balance in children ages 4–6 years. Ninety children, 42 girls and 48 boys, participated. Fifty of them were in an experimental group and followed the music and movement program, which lasted 2 months. The rest served as the control group and followed the physical education program, for the same period of time. Children's level in jumping and dynamic balance was assessed with the MOT 4–6 [Zimmer, R. & Volkamer, M. (1987). Motoriktest fuer vier-bis sechsjaehrige kinder. Manual, Belz: Weinheim]. Data were analyzed with the multivariate analysis of variance with repeated measures. The results showed that the experimental group improved significantly in both jumping and dynamic balance. It can be concluded that a developmentally appropriate music and movement program can positively affect jumping and dynamic balance of preschool children. 相似文献

This study examined the kinetic and temporal differences between countermovement jumps (CMJs) and eccentrically loaded CMJs. A survey of 109 coaches and athlete showed that 87% of respondents regularly used jumps with added mass within training. Sixteen male and thirteen female track and field athletes from sprinting, hurdling and jumping events performed 5 bodyweight CMJs 5 jumps wearing a weighted jacket and 5 eccentrically loaded dumbbell (LDB) jumps trials in a randomised order. Peak force (PF), peak power (PP), flight time (FT), concentric time (CON-T), eccentric time (ECT), total time (TIME) and eccentric/concentric ratio (E/C-Ratio) were obtained from force plate data. Statistically significant differences (p < 0.05) with moderate to large magnitude effect sizes were found between men and women in FT, PP and PF but not in any of the temporal variables. The results indicated that the WJ decreased FT in men (↓9%) and women (↓10%) but LDB jumps had similar FT to CMJ. Overall, the results showed that LDB increased the E/C Ratio (↑50% and ↑42%) and decreased CON-T (↓37% and ↓25%) compared with WJ and CMJ respectively. LDB jumping is not recommended as a training modality as it tends to disrupt the relative timing of the jump action. 相似文献

《世界末日之战》是秘鲁作家略萨的一部以巴西历史为题材的小说。小说试图通过对历史的回顾来表现对拉美历史的独特思考。小说中的时间艺术具有独特性,它一方面以明确的具体时间和自然时序来显示历史事件的客观性,另一方面又以模糊的、不确定的时间概念来展示小说特有的主观性,同时在结构安排上又通过时间的跳跃性、多层面性来呈现时间的立体性特色。 相似文献

在梳理文献资料的基础上,对电击跳跃法建立动物模型的研究进行述评,以期为后续研究提供理论参考。结果发现,电击跳跃法是近年来研究热点,其建模装置简捷、实用,但缺乏可控性;其动物选择经济、方便,但集中在鼠类;其刺激设置丰富、有效,但缺少统一性;其表现指标综合、系统、但简便性有待提升。未来研究应设计一种更加切合运动实践、能定量化、且可行性高的装置,这是研究的前提;依此还要建立相应的动物模型。 相似文献

运用文献资料法、数理统计法、逻辑分析法,对2004-2012年间参加奥运会、世锦赛男女跳高、跳远、三级跳、撑杆跳八个单项的前三名共126名运动员的竞赛成绩及其年龄特征进行统计并对其相关性进行分析,初步探讨形成这一特征的因素,为田径体能跳跃类项目的选材与训练提供参考。研究结果显示:在这四个项目中,跳远男女运动员的年龄与竞赛成绩成正相关;三级跳和撑杆跳男女运动员的年龄与竞赛成绩成负相关;跳高项目男子运动员竞赛成绩与年龄成正相关,女子运动员成负相关。因此,运动训练中应有针对性地根据不同项目、不同性别,合理地进行运动员选材、安排训练计划与人才培养,进行符合运动员自身年龄阶段特征的训练,不断挖掘其运动潜质,提高运动员竞技成绩。 相似文献
