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

ABSTRACT

The present study aimed to provide reference values for lower-limb muscle power assessed during the incremental jump squat (JS) test in elite athletes (i.e., professional athletes competing at international level). We pooled data from all JS tests performed by elite athletes of different sports in two high-performance centres between 2015 and 2019, and computed reference values (i.e., terciles) for mean power (MP), mean propulsive power (MPP), and peak power (PP). Reference values were obtained from 684 elite athletes (458 male and 226 female) of 16 different sports (boxing, judo, karate, fencing, taekwondo, wrestling, basketball, soccer, futsal, handball, rugby union, badminton, tennis, long distance running, triathlon, and sprinting). Significant differences (p < 0.001) were found between male and female athletes for MP (7.47 ± 1.93 and 6.15 ± 1.68 W·Kg^?1, respectively), MPP (10.50 ± 2.75 and 8.63 ± 2.43 W·Kg^?1), and PP (23.64 ± 6.12 and 19.35 ± 5.49 W·Kg^?1). However, the velocity at which these power measures was attained seemed to be independent of sex (~0.95, 1.00 and 2.00 m·s^?1 for mean, mean propulsive, and peak velocity, respectively) and homogeneous across different sport disciplines (coefficient of variation <10%). These data can be used to classify athletes’ power capabilities, and the optimum velocity ranges provided here could be useful for training purposes.  相似文献

基于SRPE竞速运动项目训练负荷评价方法的实证研究     

谢云  耿海峰  李赞 《中国体育科技》2020,(2):30-38

目的:基于自行车运动员的训练负荷实证评价,探讨竞速运动项目训练负荷主观感知疲劳评价(session rating of perceived exertion,SRPE)的有效性,并证明训练因素[心率(HR)、训练压力分数(TSS)、训练刺激量(TRIMP)、代谢当量(MET)、能量消耗(EE)]与非训练因素(自感疲劳、压力等级、睡眠质量、肌肉酸痛、训练积极性)对训练负荷量(SRPETL)的影响作用。方法:10名优秀职业自行车运动员(均为男性),测试开始前1周均未进行过大强度运动。运用SRPE、心率计(Garmin佳明HRM-tri)、码表(Garmin佳明edge 200)、身心恢复测试量表等对42天的高原训练负荷进行测试。内部负荷采用SRPE-TL、ETRIMP、ETRIMP、%HRmax表示,外部负荷采用TSS、MET、EE表示。结果:平均每周的SRPE-TL为5 300±1 512 AU。训练单调性(TM)为2.22±0.81 AU,训练应激(TS)为12 766±1 334 AU。SRPE-TL与各测试指标之间具有显著相关性(r=0.58~0.81)。逐步多元回归分析结果表明ETRIMP、TSS、自感疲劳、肌肉酸痛和压力等级可以解释SRPE-TL 71.8%的变异程度(Y=453.12+2.99 ETRIMP+1.20 TSS-114.81自感疲劳-111.30肌肉酸痛+85.81压力等级)。结论:SRPE是评价竞速项目训练负荷的一种有效手段,并且SRPETL是一个全域性指标,且训练因素与非训练因素均对运动员感知疲劳有影响作用。  相似文献   

成果导向的学校体育质量监测结构及运行机制研究——芬兰经验与启示     

闫静 《武汉体育学院学报》2020,54(1):78-85

成果导向是芬兰学校体育质量监测依据的主要理念。芬兰学校体育质量监测机构与政府没有隶属关系，监测人员可分为报告质量、体育课程质量、体育教师质量、体育教学质量、体育设施质量6种监测类型；监测人员经过严格的选聘程序、分类化的专业培训之后，可以根据成果导向的学生体育学习监测框架，从省级、县级、区级3个不同层面开展监测工作，监测程序由政府进行认证与规范。成果导向的芬兰学校体育质量监测结构由早期、中期、后期、执法、突击与合并6种监测类型及其相应的指标和内容构成，各类型之间环环相扣、相互补充。通过借鉴芬兰经验，突出成果导向，有利于提升学校体育质量，强化我国学校体育督导的目标性与规范性，有助于优化与改善我国学校体育质量的现有督导结构及运行机制，使其更加关注学校体育成果细化和转化的导向，促使督导评估指标朝向可测化和具体化方向发展，进而更好地发挥督导成果在助力学校体育发展方面的各类功能。  相似文献

Can sit-to-stand muscle power explain the ability to perform functional tasks in adults with severe obesity?     

Samuel T. Orange  Phil Marshall  Leigh A. Madden  Rebecca V. Vince 《Journal of sports sciences》2019,37(11):1227-1234

This study examined the relationship between sit-to-stand (STS) power and physical function in adults with severe obesity. Thirty-eight adults (age: 44 ± 12 years; body mass index [BMI]: 45.2 ± 7.8 kg/m²) completed evaluations of STS power, strength and functional performance. STS power was measured with a wearable inertial sensor, strength was assessed with the isometric mid-thigh pull, and function was measured with the timed up-and-go (TUG), six-minute walk test (6MWT) and 30-s chair STS. Power and strength (normalised to body mass) entered regression models in addition to age, gender, BMI and physical activity (daily step count). Power displayed large univariate associations with TUG (r = 0.50) and 30-s chair STS (r = 0.67), and a moderate association with 6MWT (r = 0.49). Forward stepwise regression revealed that power independently contributed to TUG (β = ?0.40, p = 0.010), 30-s chair STS (β = 0.67, p < 0.001) and 6MWT performance (β = 0.27, p = 0.007). Power also appeared to be a superior determinant of function compared with strength. Power generated via the STS transfer largely underpins the ability to perform functional tasks in adults with severe obesity, although intervention studies are required to investigate a potentially causal relationship.  相似文献

ABSTRACT

We performed a randomized, controlled trial to analyse the effects of resistance training (RT) on cognitive and physical function among older adults. Fifty participants (mean age 67 years, ~60% woman) were randomly assigned to an RT program or a control group. Participants allocated to RT performed three sets of 10-15RM in nine exercises, three times per week, for 12-weeks. Control group did not perform any exercise. Variables included cognitive (global and executive function) and physical function (gait, mobility and strength) outcomes. At completion of the intervention, RT was shown to have significantly mitigated the drop in selective attention and conflict resolution performance (Stroop test: -494.6; 95%CI: -883.1; ?106.1) and promoted a significant improvement in working memory (digit span forward: -0.6; 95%CI: ?1.0; ?0.1 and forward minus backward: -0.9; 95% CI: ?1.6; ?0.2) and verbal fluency (animal naming: +1.4, 95%CI 0.3, 2.5). No significant between-group differences were observed for other cognitive outcomes. Regarding physical function, at completion of the intervention, the RT group demonstrated improved fast-pace gait performance (?0.3; 95% CI: ?0.6; ?0.0) and 1-RM (+21.4 kg; 95%CI: 16.6; 26.2). No significant between-group differences were observed for other mobility-related outcomes. In conclusion, RT improves cognitive and physical function of older adults.  相似文献
