文化功能视角下江口“金钱杆”的发展逻辑研究     

陈伟 《中华武术(研究)》2021,(1):119-121

文化功能也就是"出之于人,归之于人",江口土家族"金钱杆"起于秦末时期的西楚霸王,形于族人生产生活实践中。经过研究发现,"金钱杆"是具有彰显土家族文化的独特符号、"常"与"非常"之间转换的独特节点、教化孩童的重要载体以及增强体质的独特途径的少数民族传统体育活动。本研究主要探求"金钱杆"发展逻辑,旨在为"金钱杆"的传承和发展提供有益的指导。  相似文献   

人本关怀理念下普通高校体育课程改革探究     

戴飞 《体育科技文献通报》2020,(2):45-47

在升学与就业的双重压力下,无论学校、教师还是大学生本人都对普通高校体育课程存在不同程度的忽视心理与忽视行为。从体育课程的教学形式、教学内容、教学时长来看,并没有起到促进大学生综合素质提升的作用,也没有对高等教育体系完善做出应有的贡献。而在教学过程中,大学生的个人意愿、学习的主观能动性也没有得到挖掘与激发。可以说,大学体育课程缺乏以人为本的教学理念。这些问题成为大学体育课程亟待改革的弊端。  相似文献   

花样游泳运动员功能性动作能力与力量素质的相关性研究     

陈文佳  章碧玉  沈兆喆 《中国体育科技》2020,(2):71-80,F0003

目的:探讨我国优秀花样游泳运动员功能性动作能力与力量素质的相关性,分析功能动作筛查测试与力量素质测试结果存在的内在联系,从专项视角探讨花样游泳运动项目的训练策略并提出建议。方法:选取国家花样游泳队14名健将级运动员为研究对象,对其进行FMS、握力、上肢力量、股内收肌群力量、躯干核心耐力、下肢爆发力测试,并对测试结果进行相关性分析。结果:1)14名花样游泳运动员FMS测试平均得分为15.21分,有5人测试得分低于运动损伤高风险的临界值(14分);2)FMS测试总分与Keiser坐姿上推(偏相关系数=0.622,P<0.05)、45°股内收肌群横向收缩力量(偏相关系数=0.652,P<0.05)、90°股内收肌群横向收缩力量(偏相关系数=0.746,P<0.01)均呈正相关;3)直线弓步蹲与Keiser坐姿上推(偏相关系数=0.711,P<0.05)、无反向纵跳(偏相关系数=0.661,P<0.05)、有反向纵跳(偏相关系数=0.614,P<0.05)和40 cm跳深跳高(偏相关系数=0.754,P<0.01)均呈正相关;肩部灵活性测试得分与Keiser下蹲上推(偏相关系数=0.575,P<0.05)、45°股内收肌群横向收缩力量(偏相关系数=0.585,P<0.05)以及90°股内收肌群横向收缩力量(r=0.867,P<0.01)均呈正相关,与仰桥耐力呈负相关(偏相关系数=0.701,P<0.05);旋转稳定性与40 cm跳深跳高呈正相关(偏相关系数=0.575,P<0.05)。结论:我国优秀花样游泳运动员髋关节主动灵活性和臀大肌-髂胫束联合等肌群的主动柔韧性较好,但存在膝关节、髋关节稳定性差、躯干核心区肌群控制力不足等问题,受主导臂和主导腿均为右侧影响,运动员身体两侧不平衡明显。运动员FMS测试得分并不能全面反映其力量素质的高低,FMS测试得分与部分力量素质测试结果存在相关性,可能与两种测试均涉及同一动力链结构系统肌群的协同工作和动作存在做功类型的相似性有关。  相似文献   

Power training in elite young soccer players: Effects of using loads above or below the optimum power zone     

Irineu Loturco  Lucas A. Pereira  Valter P. Reis  Chris Bishop  Vinicius Zanetti  Pedro E. Alcaraz 《Journal of sports sciences》2020,38(11-12):1416-1422

ABSTRACT

This study aimed to examine the effects of two jump squat (JS) training programs involving different loading ranges in under-20 soccer players during a preseason period. Twenty-three elite young soccer players performed sprint speed (at 5-, 10-, and 20-m), change-of-direction (COD) speed, JS peak-power (PP), and countermovement jump (CMJ) tests pre and post four weeks of training. Athletes were pair-matched in two groups according to their optimum power loads (OPL) as follows: lower than OPL (LOPL; athletes who trained at a load 20% lower than the OPL) and higher than OPL (HOPL; athletes who trained at a load 20% higher than the OPL). Magnitude-based inferences were used to compare pre- and post-training measures. Meaningful increases in the PP JS were observed for both groups. Likely and possible improvements were observed in the 5- and 10-m sprint velocity in the LOPL group. Meanwhile, possible and likely improvements were observed in the CMJ, 5- and 10-m sprint velocity, and COD speed in the HOPL group. Overall, both training schemes induced positive changes in athletic performance. Soccer coaches and sport scientists can implement the JS OPL-based training schemes presented here, either separately or combined, to improve the physical performance of youth soccer players.  相似文献   

Does spatial awareness training affect anatomy learning in medical students?     

Rene A. Gonzales  Gordon Ferns  Marc A. T. M. Vorstenbosch  Claire F. Smith 《Anatomical sciences education》2020,13(6):707-720

Spatial ability (SA) is the cognitive capacity to understand and mentally manipulate concepts of objects, remembering relationships among their parts and those of their surroundings. Spatial ability provides a learning advantage in science and may be useful in anatomy and technical skills in health care. This study aimed to assess the relationship between SA and anatomy scores in first- and second-year medical students. The training sessions focused on the analysis of the spatial component of objects' structure and their interaction as applied to medicine; SA was tested using the Visualization of Rotation (ROT) test. The intervention group (n = 29) received training and their pre- and post-training scores for the SA tests were compared to a control group (n = 75). Both groups improved their mean scores in the follow-up SA test (P < 0.010). There was no significant difference in SA scores between the groups for either SA test (P = 0.31, P = 0.90). The SA scores for female students were significantly lower than for male students, both at baseline and follow-up (P < 0.010). Anatomy training and assessment were administered by the anatomy department of the medical school, and examination scores were not significantly different between the two groups post-intervention (P = 0.33). However, participants with scores in the bottom quartile for SA performed worse in the anatomy questions (P < 0.001). Spatial awareness training did not improve SA or anatomy scores; however, SA may identify students who may benefit from additional academic support.  相似文献   

Efficacy of using non-linear pedagogy to support attacking players’ individual learning objectives in elite-youth football: A randomised cross-over trial     

Simon J. Roberts  James R. Rudd  Matthew J. Reeves 《Journal of sports sciences》2020,38(11-12):1454-1464

ABSTRACT

The present study examined the efficacy of a coaching curriculum, based on non-linear pedagogy, on improving attacking players’ individual learning objectives (ILOs) in elite-youth football. Participants included 22 attacking players (i.e., centre-forwards, wide-players and attacking midfield players) from a professional football academy in England. The players were randomly appointed to both control (CON) and intervention (INT) periods following baseline measures. The INT (non-linear) and CON (linear) periods were both designed to support the ILOs provided to each player as part of the elite player performance plan. The study adopted a randomised cross-over design and ILOs considered important for attacking players (i.e., strong foot finishing, weak foot finishing, 1-v-1 and decision-making) were evaluated using the Loughborough Shooting Skill Test. The results showed significant differences for INT in 1-v-1 (P< 0.02) and decision-making (P< 0.01). However, there were no significant differences for strong foot finishing, weak foot finishing or time taken. These results support non-linear pedagogy in developing 1-v-1 game play and decision-making but not for technical shooting proficiency.  相似文献

Building a coordination system of HRD,research and industry for knowledge and technology-driven economic development in South Asia     

《International Journal of Educational Development》2020

Using a tripartite framework, this study examines the current level of coordination among human resource development (HRD), research, and industry in four South Asian countries—Bangladesh, India, Nepal, and Sri Lanka. Drawing on prior literature, statistical data, and opinions from local experts, this study found that university education oft lacked labor market relevance, and that collaboration efforts between universities, research institutes, and industries had much room for improvement. To promote coordination among HRD, research, and industry for knowledge and technology-driven economic development in South Asia, this study recommends that inclusive coordination should be given higher priority over bilateral university-industry linkages. This study also argues in favor of a government-led approach in the short term, to complement the current laissez-faire approach. This study ends with policy recommendations to enhance coordination and governance based on the above-mentioned findings.  相似文献
