从个体社会化的理论视角,阐述了社会化的内涵以及中国人个体社会化的特点.指出,体育休闲是个体社会化的一种途径,它可以促进参与者社会互动交往和社会群体融入,帮助参与者更好地适应社会角色和解放个体身心,有助于参与者提升自我实践能力和养成责任意识;以"广场舞""跑吧""驴友"三项体育休闲活动为例,具体分析其对于参与者个体社会化所具有的价值和所发挥的作用,认为应注意近年来体育休闲中出现的问题,合理管控不利因素,推动国民体育休闲水平的进一步提升.  相似文献   

Are gait characteristics and ground reaction forces related to energy cost of running in elite Kenyan runners?

The aim of this study was to determine whether gait cycle characteristics are associated with running economy in elite Kenyan runners. Fifteen elite Kenyan male runners completed two constant-speed running sets on a treadmill (12 km ·h^?1 and 20 km ·h^?1). VO₂ and respiratory exchange ratio values were measured to calculate steady-state oxygen and energy cost of running. Gait cycle characteristics and ground contact forces were measured at each speed. Oxygen cost of running at different velocities was 192.2 ± 14.7 ml· kg^?1· km^?1 at 12 km· h^?1 and 184.8 ± 9.9 ml· kg^?1· km^?1 at 20 km· h^?1, which corresponded to a caloric cost of running of 0.94 ± 0.07 kcal ·kg^?1·km^?1 and 0.93 ± 0.07 kcal· kg^?1· km^?1. We found no significant correlations between oxygen and energy cost of running and biomechanical variables and ground reaction forces at either 12 or 20 km· h^?1. However, ground contact times were ~10.0% shorter (very large effect) than in previously published literature in elite runners at similar speeds, alongside an 8.9% lower oxygen cost (very large effect). These results provide evidence to hypothesise that the short ground contact times may contribute to the exceptional running economy of Kenyan runners.  相似文献   

Trait Affection Given and Received: A Test of Hofstede’s Theoretical Framework     

Daniel H. Mansson  Aldís G. Sigurðardóttir 《Journal of Intercultural Communication Research》2017,46(2):161-172

This study sought to address Hofstede and McCrae’s (2004) call for systematic cross-cultural comparisons of trait-like attributes. Specifically, we examined the extent to which Danish, Icelandic, Polish, and American adults’ trait affection given and trait affection received are (a) dependent on national origin, and (b) associated with Hofstede’s dimensions of cultures (i.e. individualism-collectivism, masculinity-femininity, power distance, and uncertainty avoidance). The participants (N = 606) completed a questionnaire in English that consisted of the trait affection given and trait affection received scales. Results of a multivariate analysis of variance and linear regression analyses revealed that people’s trait affection given and received are (a) dependent on national origin, and (b) associated with Hofstede’s dimensions of cultures.  相似文献

Cultural distance and expatriate job satisfaction     

Fabian Jintae Froese  Vesa Peltokorpi 《Int J Intercult Relat》2011,35(1):49-60

Despite its strong impact in domestic settings on job performance, organizational commitment, stress, and turnover intentions, job satisfaction has received little attention in the literature on expatriates. This paper analyzes the predictors of job satisfaction that may arise in an expatriate context. Drawing on the cultural distance perspective, we propose that the national cultural distance, supervisor's nationality, host-country language proficiency, expatriate type, and company nationality are important determinants of expatriate job satisfaction. Survey results from 148 expatriates in Japan demonstrate that national cultural distance, supervisor's nationality, and expatriate type have a statistically significant influence on expatriate job satisfaction. Theoretical and practical implications are provided.  相似文献

我国高水平短跑运动员途中跑摆动技术的肌肉用力特征     

张杰  吴瑛  康文峰 《上海体育学院学报》2011,(5)

运用表面肌电遥测和高速摄像同步测试方法,揭示我国部分高水平短跑运动员途中跑摆动技术的肌肉用力特征。结果表明:短跑途中跑摆动技术的肌电特征表现为明显的时序性,肌肉间的收缩具有高度协调性。折叠前摆阶段,摆动腿屈髋肌的主要电位活动是在摆动初期:运动员足蹬离地面至(另一腿)垂直支撑时刻前;垂直支撑时刻后,摆动腿股二头肌长头、半腱肌的活动明显,活动时间较长;下压着地阶段,其工作性质由被动拉长转为向心收缩使髋关节伸,同时还作用于膝关节使膝关节屈,神经肌肉活动的机制十分复杂。在专项力量训练实践中,教练员应结合摆动腿髋关节屈伸肌群的发力特点,优选专项力量训练的手段,提高训练效果。  相似文献
