苏区少年先锋队述略     

邵雍 《江西师范大学学报(哲学社会科学版)》2007,40(4):80-87

土地革命时期的少年先锋队是一个革命青年的半武装组织。在中国共产党、共青团和苏维埃政府的关心下,少年先锋队领导苏区青年为争取自身阶级利益,保卫苏维埃政权,努力学习知识,并积极投身于革命运动中。他们参与阶级斗争,帮助政府实现各项政治经济政策;开展拥军优属活动,帮助工农群众进行生产建设;训练和培养了大批红军后备力量,帮助红军、赤卫军、游击队保卫苏区政府和人民的安全,并为前线输送了大量优秀战士。在近代中国青年运动史上,少年先锋队组织有着不可磨灭的伟大贡献。  相似文献   

Inter-participant variability in daily physical activity and sedentary time among male youth sport footballers: independent associations with indicators of adiposity and cardiorespiratory fitness     

Sally A. M. Fenton  Joan L. Duda  Timothy Barrett 《Journal of sports sciences》2016,34(3):239-251

Participation in youth sport is assumed to promote and contribute towards more physically active lifestyles among children and adolescents. The aim of this study was to examine inter-participant variability in objectively measured habitual physical activity (PA) behaviours and sedentary time among youth sport participants and their implications for health. One-hundred-and-eighteen male youth sport footballers (Mean ± s = 11.72 ± 1.60) wore a GT3X accelerometer for 7 days. Average daily PA [min · day^?1, in light (LPA), moderate (MPA), vigorous (VPA) and combined moderate-to-vigorous (MVPA)] and sedentary time were calculated. Participants’ body mass index adjusted for age and sex (BMI–standard deviation score), per cent body fat (BF%), waist circumference and cardiorespiratory fitness were assessed. Results revealed that variability in daily PA behaviours and sedentary time (min · day^?1) was associated with BMI–standard deviation score [VPA (?), MVPA (?)], BF% [sedentary time (+), VPA (?), MVPA (?)], waist circumference [sedentary time (+), LPA (?)] and cardiorespiratory fitness [sedentary time (?), MPA (+), VPA (+), MVPA (+)]. Whilst sedentary time and MVPA were not related to health outcomes independent of one another, associations with markers of adiposity and cardiorespiratory fitness were stronger for sedentary time. Sedentary time was also significantly positively related to waist circumference independent of VPA. Results demonstrate inter-participant variability in habitual PA and sedentary time among youth sport participants which holds implications for their health. Thus, promoting PA and, in particular, reducing sedentary time may contribute towards the prevention of adverse health consequences associated with a physically inactive lifestyle for children and adolescents active in the youth sport context.  相似文献   

Positional group significantly influences the offensive and defensive skill involvements of junior representative rugby league players during match play

This study examined the skill involvements of three positional groups across a junior representative rugby league season. Data were collected from 45 rugby league players (mean ± SD; age = 16.5 ± 1.0 years) currently participating in the Harold Matthews and SG Ball Cup. Players were subdivided into hit-up forwards, adjustables and outside backs. The frequency (n · min^?1) of offensive, defensive and overall involvements was coded for each group using a notation system and a practical coach skill analysis tool. Multivariate analysis of variance (MANOVA) revealed a significant effect of playing position on skill involvements (F = 9.06; P < 0.001; ES = 0.41). Hit-up forwards performed a significantly greater frequency of offensive (0.31 ± 0.10), defensive (0.42 ± 0.15) and overall involvements (0.74 ± 0.19) when compared to adjustables (0.20 ± 0.08, 0.28 ± 0.08 and 0.52 ± 0.15, respectively) and outside backs (0.20 ± 0.12, 0.11 ± 0.07 and ± 0.31 ± 0.17, respectively). Further, adjustables performed a significantly greater number of defensive (0.28 ± 0.08) and overall involvements (0.52 ± 0.15) when compared to outside backs (0.11 ± 0.07 and 0.31 ± 0.17, respectively). The findings of this study suggest that it is important to consider a junior player’s positional group when analysing their skill involvements. Information gained from this study could assist in the design of specific training methodologies for junior rugby league players in high-level talent development programmes.  相似文献   

Coordination pattern of baseball pitching among young pitchers of various ages and velocity levels     

Hsiu-Hui Chen  Chiang Liu  Wen-Wen Yang 《Journal of sports sciences》2016,34(17):1682-1690

This study compared the whole-body movement coordination of pitching among 72 baseball players of various ages and velocity levels. Participants were classified as senior, junior, and little according to their age, with each group comprising 24 players. The velocity levels of the high-velocity (the top eight) and low-velocity (the lowest eight) groups were classified according to their pitching velocity. During pitching, the coordinates of 15 markers attached to the major joints of the whole-body movement system were collected for analysis. Sixteen kinematic parameters were calculated to compare the groups and velocity levels. Principal component analysis (PCA) was conducted to quantify the coordination pattern of pitching movement. The results were as follows: (1) five position and two velocity parameters significantly differed among the age groups, and two position and one velocity parameters significantly differed between the high- and low-velocity groups. (2) The coordination patterns of pitching movement could be described using three components, of which the eigenvalues and contents varied according to age and velocity level. In conclusion, the senior and junior players showed greater elbow angular velocity, whereas the little players exhibited a wider shoulder angle only at the beginning of pitching. The players with high velocity exhibited higher trunk and shoulder rotation velocity. The variations among groups found using PCA and kinematics parameter analyses were consistent.  相似文献

In a practical mood: Studying for a profession in the changing kibbutz     

Arza Avrahami  Yechezkel Dar 《Higher Education》2004,47(1):51-71

The influence of recent social and economicchanges in the Israeli kibbutz on the prolongedstage of youth was examined with respect tohigher education. The young people on thekibbutz of the late 1990s appear lessmoratorial and more instrumental about theirfuture and commence higher education earlierthan in previous age cohorts. When starting tostudy, their educational and professionalprospects are crystalized as those of thenon-kibbutz student. Most of them opt foracademic, degree-granting studies, but a higherpercentage than among the general populationprefer vocation-oriented colleges to theresearch oriented universities. In choosingfields of study, they prefer more appliedstudies like engineering, social services andpractical arts and are less likely to choosesciences and the humanities. De-communalizationand economic instability of the kibbutz,inadequate preparation in kibbutz high schoolsfor the competitive admission to theuniversities, exposure to a restricted range ofoccupations during adolescence, and lack of acultural tradition supportive of elitiststudies may explain this practical mood, moresalient among kibbutz women.  相似文献

‘Upturned participation’ and youth work: using a Critical Utopian Action Research approach to foster engagement     

Ditte Tofteng  Mette Bladt 《Educational Action Research》2020,28(1):112-127

ABSTRACT

This article reflects on how participatory processes inspired by action research hold a genuine potential for developing social educational work in a more democratic way. We present our concept of ‘Upturned Participation’, which is built upon the methodological framework of Critical Utopian Action Research. First Critical Utopian Action Research is introduced briefly, including a presentation of the core method of the action research approach. We then present an extract from an action research project aimed at creating space for participation for marginalized young people in the area of Copenhagen. On this basis, we reflect on how the ideas of the young people could influence the field of social work. The article addresses contemporary challenges and opportunities for creating development in the field of youth work or social work through participatory processes with marginalized young people.  相似文献
