网球发球技术系统观及合成协同训练体系研究     

蒋宏伟 《成都体育学院学报》2016,(1):61-65

通过分析我国网球运动员与世界优秀运动员在发球技术环节上的差距,否定了有关发球可完全由发球者自由操控的片面发球观,首次提出应将发球视作为一个完整体系的发球系统观,指出优秀网球运动员的发球应追求合成与协调效应,具体包括:(1)从静态到动态合成和协同;(2)发球各个相关要素(学科)之间合成和协同;(3)由外在到内在合成协同. 本研究在提出了"发球系统说"的基础上,构建了网球发球合成协同训练体系:(1)优先发展协调性,统摄发球诸环节,达成发球训练合成和协同效应;(2)注重发球与下一拍技术间的衔接,实现合成协同效应;(3)纵向一体融通,发挥身体的整体能力;(4)增效节"能",升华合成协调效应;(5)形成个体最佳发球节奏.  相似文献   

我国体育政策执行效果的影响因素探索     

张德军  杜少辉 《广州体育学院学报》2016,(5):1-4

以政策过程为研究切入点,利用文献资料法和逻辑分析法,认为影响体育政策执行的主要因素有:体育政策问题认定、体育政策文本、政策执行主体、执行客体、执行工具和执行环境等.为提高体育政策执行效应,应强化对体育政策问题的认定,并出台条款明确、措施完善的政策文本;在具体执行环节,应平衡执行主体的利益博弈,并提高政策执行客体的认知程度;利用相对综合性的政策执行工具,有效降低不同政策执行的冲突,体现共容利益的引导作用.  相似文献

The role of adult attachment in international students’ acculturation process     

《Int J Intercult Relat》2021

International students face a variety of challenges in their acculturation process. Acculturation, the process of adapting to a new cultural environment, is highly variable and influenced by environmental and individual factors that exist before or arise during acculturation. Among the moderating personal factors existing prior to acculturation, adult attachment has received attention as an important variable impacting the acculturation process and adaptation outcomes. Based on the bi-dimensional model of acculturation (Berry, 1997) and the concept of adult attachment (Bowlby, 1977), the current study hypothesized that an insecure attachment (i.e., high attachment anxiety and avoidance) would predict more acculturative stress, less psychological adaptation, and less sociocultural adaptation. We also hypothesized that students who highly identified with their heritage culture and were highly acculturated to the U.S. culture would experience higher levels of psychological and sociocultural adaptation. Also, we examined if adult attachment moderated the effects of acculturation on international students’ psychological and sociocultural adaptation. International students enrolled in higher education institutions in different geographic locations in the United States (N = 221) completed measures of adult attachment, acculturation, acculturative stress, and psychological and sociocultural adaptation. The results suggested that attachment anxiety was a significant predictor of international students’ psychological adaptation. High acculturation to the U.S. significantly predicted more sociocultural adaptation. Attachment avoidance significantly moderated the effect of acculturation to the U.S. culture on international students’ psychological distress, while attachment anxiety was a significant moderator for the effect of acculturation to the U.S. culture on sociocultural adaptation.  相似文献   

Severe interpersonal violence against children in sport: Associated mental health problems and quality of life in adulthood     

《Child abuse & neglect》2018

In a recent large-scale prevalence study of interpersonal violence (IV) against child athletes in the Netherlands and Belgium we found that 9% of adult respondents who participated in organized sports before the age of 18 had experienced severe psychological violence, 8% severe physical violence, and 6% severe sexual violence in various sport settings. While the general literature has repeatedly shown that exposure to IV during childhood is associated with mental health problems in adulthood and to a lesser extent with reduced quality of life (QOL), these relationships have not been demonstrated in (former) athletes. Thus, the current study aims to assess the association of severe childhood IV in sport and adult wellbeing. Depression, anxiety, and somatization were assessed in the same general population sample (N = 4043) using the Brief Symptom Inventory (BSI-18) and QOL with the World Health Organization Quality of Life questionnaire (WHOQOL-Brèf). The association between severe IV in sport and adult wellbeing was investigated using multiple linear regression while controlling for demographics, recent life events, and relatives’ psychological problems. We found severe sexual, physical, and psychological childhood IV in sport to be associated with more adult psychological distress and reduced QOL. Polyvictimization shows the strongest correlation with poorer wellbeing and QOL. Recent life events, relatives’ psychological problems, marital status, and level of education were significant covariates in the psychological symptoms and QOL assessed. We hope that these new insights prompt sport administrators to implement broad spectrum child protection measures and raise the awareness of mental health professionals about the necessity to also screen for adverse childhood experiences in the sport context.  相似文献
