论发展运动员速度力量的训练方法

速度力量是速度与力量的综合表现,它的提高受速度素质与力量素质的牵制。力量和速度是决定快速能力的发展因素。速度力量的典型表现形式是爆发力、起动力、反应力。爆发力的提高有赖于最大力量的发展,快速用力、超等长练习法是发展爆发力的有效方法。起动力的提高与最大力量密切相关,采用专门练习对发展起动力有积极作用。反应力包括弹跳反应力和击打反应力,超等长练习是发展弹跳反应力的有效手段;退让练习、模仿练习对发展击打反应力有促进作用。     

学习力与文化力——企业生存与持续发展的无形支柱

相对于正式的组织结构和经营管理制度而言,学习力与文化力是构成企业组织系统的无形支柱。学习力是企业的生命所在,而文化力是企业的灵魂体现。缺乏学习力的企业好比一个存在智力障碍的个体,必将为竞争大潮和风云变幻的世界所淘汰;而失去文化力的企业尤如没有灵魂的肉体,无法形成强大的凝聚力、向心力和战斗力。

大学生道德能力作为大学生综合能力的重要组成部分在互联网时代下受到了严重影响。新时期的高校德育工作要想取得显著成效,有必要对大学生道德能力的现状进行研究分析,探索新方法,利用信息技术加强和改进大学生道德能力建设。     

顶岗实习高师生教师专业技能指导模式论析

顶岗实习中高师生教师专业能力成长具有特殊的路径。当前的指导模式主要有跟队指导、基础教育学校指导、名师培训、专家讲座、班主任指导等,在过程中有着顶岗与实习之间的矛盾、成长与培养的交替、实践与学习之间的共同发展、压力与奉献精神的催生等特点。在指导模式的发展上,要注意采取多种指导模式结合的系统模式,并注意提供一个较为宽松的工作环境,以利于高师生的自我成长。

我国男子高水平三级跳远运动员专项力量训练安排研究

摘要：男子三级跳远是我国参加奥运会田径比赛的潜优势项目,专项力量是影响三级跳远比赛成绩和技术水平提升的关键因素,运用文献资料法、专家访谈法、实地调查等研究方法,分析研究我国最优秀的6名男子三级跳远运动员专项力量训练安排。结论：1）我国男子高水平三级跳远运动员的力量训练内容、方法手段、计划与负荷基本符合世界潮流,但训练中缺少单腿支撑进行的蹲、拉、提、举等练习,不够贴近专项需要;2）专项力量训练器材与世界发达国家相比科技化含量不高;3）专项力量负荷调整控制主要依赖教练员经验与身体素质指标推算。

Temporal specificity of training: intra-day effects on biochemical responses and Olympic-Weightlifting performances

The aim of this study was to investigate the performance of an Olympic-Weightlifting session training at three times of the day on the performance related to biochemical responses. Nine weightlifters (21 ± 0.5 years) performed, in randomised order, on three Olympic-Weightlifting training (snatch, clean and jerk) sessions (08:00 a.m., 02:00 p. m., 06:00 p. m.). Blood samples were collected: before, 3 min and 48 h after each training session. Haematological parameters and markers of muscle injury were assessed. Resting oral temperature and rating of perceived exertion (RPE) were also assessed during each session. ANOVA showed that the performance was better (P < 0.001) at 02:00 p. m. with a less RPE (P < 0.01) compared to the morning and the evening sessions while there was higher (P < 0.05) oral temperature at 06:00 p. m. versus 08:00 a.m. and 02:00 p. m. Muscle damage changed immediately (without significant effect after 48 h) after the training sessions with lower values ??in the evening compared to the morning. In conclusion, the afternoon training is more effective than morning or evening sessions for weightlifters. Therefore, coaches and weightlifters should be advised to schedule their training session in the afternoon hour.     

Indicators of sailing performance in youth dinghy sailing

Abstract

This study aimed to determine indicators of sailing performance in 2 (age) groups of youth sailors by investigating the anthropometric, physical and motor coordination differences and factors discriminating between elite and non-elite male optimist sailors and young dynamic hikers. Anthropometric measurements from 23 optimist sailors (mean ± SD age = 12.3 ± 1.4 years) and 24 dynamic youth hikers (i.e. Laser 4.7, Laser radial and Europe sailors <18 years who have to sail the boat in a very dynamic manner, due to a high sailor to yacht weight ratio) (mean ± SD age = 16.5 ± 1.6 years) were conducted. They performed a physical fitness test battery (EUROFIT), motor coordination test battery (Körperkoordinationstest für Kinder) and the Bucket test. Both groups of sailors were divided into two subgroups (i.e. elites and non-elites) based on sailing expertise. The significant differences, taking biological maturation into account and factors discriminating between elite and non-elite optimist sailors and dynamic hikers were explored by means of multivariate analysis of covariance and discriminant analysis, respectively. The main results indicated that 100.0% of elite optimist sailors and 88.9% of elite dynamic hikers could be correctly classified by means of two motor coordination tests (i.e. side step and side jump) and Bucket test, respectively. As such, strength- and speed-oriented motor coordination and isometric knee-extension strength endurance can be identified as indicators of sailing performance in young optimist and dynamic youth sailors, respectively. Therefore, we emphasise the importance of motor coordination skill training in optimist sailors (<15 years) and maximum strength training later on (>15 years) in order to increase their isometric knee-extension strength endurance.
