立定跳远教学中TGMD-2的应用研究     

刘上元  杨宁  胡丽萍 《湖北体育科技》2016,(3):252-253

目的:对立定跳远教学进行干预,采用儿童大肌肉群动作发展测试量表(以下简称TGMD-2量表)进行过程性测量,观察干预教学对儿童立定跳远动作发展的影响,寻求发展儿童下肢大肌肉群的有效途径。方法:1)干预前后使用TGMD-2量表对学生立定跳远动作进行评分,并测量远度,进行比较;2)对实验组立定跳远教学进行干预,对照组不做干预。结果:实验组立定跳远评分与远度测量显著提高;对照组评分显著下降,远度测量上升。结论:1)运动干预可以促进儿童立定跳远动作发展;2)儿童动作发展成熟之前可采用TGMD-2量表进行过程性评价。  相似文献

Force–velocity property of leg muscles in individuals of different level of physical fitness

The present study explored the method of testing muscle mechanical properties through the linear force–velocity (F–V) relationships obtained from loaded vertical jumps. Specifically, we hypothesised that the F–V relationship parameters depicting the force, power, and velocity of the tested muscles will differ among individuals of different physical fitness. Strength trained, physically active, and sedentary male participants (N = 10 + 10 + 10; age 20–29 years) were tested on maximum countermovement and squat jumps where manipulation of external loads provided a range of F and V data. The observed F–V relationships of the tested leg muscles were approximately linear and mainly strong (median correlation coefficients ranged from 0.77 to 0.92; all p < 0.05), independently of either the tested group or the jump type. The maximum power revealed higher values in the strength trained than in the physically active and sedentary participants. This difference originated from the differences in F-intercepts, rather than from the V-intercepts. We conclude that the observed parameters could be sensitive enough to detect the differences among both the individuals of different physical fitness and various jump types. The present findings support using loaded vertical jumps and, possibly, other maximum performance multi-joint movements for the assessment of mechanical properties of active muscles.  相似文献   

Physical activity profiles and selected muscular fitness variables in English schoolchildren: A north–south divide?     

Lee Ingle  Ashlie Stephenson  Gavin R. Sandercock 《European Journal of Sport Science》2016,16(8):1187-1196

The aim of the study was to compare and contrast habitual physical activity (PA) profiles and muscular fitness in schoolchildren from northern and southern regions of England. Data were collected from two secondary schools in the north east (NE) of England. The study procedures followed methods employed by the East of England Healthy Hearts Study in 10–16-year-old boys and girls based in the south east (SE) region of England and data were compared. Habitual physical activity (PAQ-A), vertical jump test, and hand-grip (HG) strength were assessed. We converted raw scores from all assessments to age- and sex-normalised z-scores. We recruited 597 children (58% boys) in the NE and compared findings to 597 age- and sex-matched boys and girls from the SE. Boys in the SE had significantly stronger HG scores, jumped higher, were more powerful (mean peak power: 2131?W vs. 1782?W; P?P?P?相似文献

高杰  迈夫 《乌鲁木齐成人教育学院学报》2004,12(3):6-8

亚元的创建是一个长期、复杂的过程，因而亚洲的合作进程只能是循序渐进的。就亚洲整体而言，也许要经过数十年的发展和努力，亚洲经济一体化才会有长足的发展，妨碍亚洲实现统一货币的种种障碍才能得以消除，也只有到那时才能真正建立起涵盖整个亚洲的统一货币。  相似文献
