摘要：目的：考察社会支持对运动员投入的影响以及心理坚韧性和应对方式在其中的序列中介作用。方法：采用运动领域领悟支持问卷、运动心理坚韧性问卷、竞技运动领域应对问卷、运动员投入问卷对483名现役运动员进行调查。结果：1）社会支持对运动员投入有显著的正向预测作用;2）心理坚韧性与应对方式在社会支持与运动员投入之间起中介作用。结论：社会支持不仅能直接促进运动员投入，还可以通过心理坚韧性与应对方式的中介对其产生间接促进作用，具体包括4条中介路径：通过心理坚韧性的中介路径；通过任务导向应对的中介路径；通过心理坚韧性与任务导向应对的序列中介路径；通过心理坚韧性与脱离导向应对的序列中介路径。本研究构建的中介效应模型在一定程度上揭示了社会支持影响运动员投入的内在机制。研究提示，通过提供社会支持，将能增强运动员的心理坚韧性，促使其更多地采用任务导向应对，更少地采用脱离导向应对，进而促进运动员投入。  相似文献   

基于多普勒频谱图的力量项目运动员左室舒张期室壁运动研究     

张戈  李献震  田金凯 《吉林体育学院学报》2016,(1):57-61

通过测定和比较正常人和力量项目运动员在静息和逐级递增负荷运动时，室壁多普勒频谱图上E波和A波峰值速度，研究左室后壁主动松弛和被动充盈功能的变化。结果表明：在静息状态，力量项目组房缩期心房收缩对于左室舒张充盈的贡献小于正常组；在逐级递增负荷中，力量项目组心脏舒张功能的动员表现为同时动用主动舒张储备和左房收缩储备，显示出心脏主动舒张的能力强，左房收缩储备大。  相似文献

上海女子气手枪运动员击发和收枪时脑电相干性分析          下载免费PDF全文

安燕  郑樊慧 《体育科研》2016,(6):83-87

通过脑电相干性分析,探讨运动员射击中击发和收枪两种不同运动表现时各脑区间的沟通差异。采用64导脑电测试系统记录12名女子气手枪运动员击发与收枪时的脑电,将两种不同表现击发前的脑电分为4个时间段（每段1 000 ms）,分别计算低-alpha频段（8~10 Hz）、高-alpha频段（11~13 Hz）、低-beta频段（14~22 Hz ）中前额区（Fz）与其他脑区间(额区、中央区、顶区、枕区和颞区)的相干性。结果发现,在低-alpha频段,与收枪时相比,运动员击发时大脑信息沟通较少,表明击发时运动员只需要较低的皮层唤醒和注意努力。左脑脑波相干性显著低于右脑,表明大脑半球不同功能体现在了运动员射击过程中,运动员射击时右半球交流多,注意力转移以视觉空间为主。不同表现过程中不同时间点显示了不同高低的脑波相干性,故推断稳定的大脑皮质活动与较好的运动表现有关。  相似文献

Eating disorder prevention initiatives for athletes: A review     

Rachel J. Bar  Stephanie E. Cassin  Michelle M. Dionne 《European Journal of Sport Science》2016,16(3):325-335

A substantial amount of evidence suggests that collegiate and elite athletes involved in weight-sensitive sports are at greater risk of developing eating disorders (EDs) than the general population. With the limited effectiveness of treatment for EDs, prevention of EDs has been broadly considered in the literature. The present paper reviewed the existing literature on ED prevention programmes for athletes in order to determine the current status of prevention programmes and recommend future directions. The available literature suggests that selective, primary interventions with multiple targets and an interactive multimodal approach appear most effective. Current challenges in the field, including lack of longitudinal research, hesitation by the sport community to be involved in ED research and poor cross-field communication and collaboration, are also explored. The lack of dissemination of evidence-based prevention programmes and the simultaneous promotion of prevention programmes that have not yet been empirically examined are also discussed. Based on these observations future directions are recommended.  相似文献   

First-rib stress fracture in two adolescent swimmers: a case report     

Sara Low  Michael Kern 《Journal of sports sciences》2016,34(13):1266-1270

First-rib stress fractures have been described in adolescent athletes in various sports, with only one prior case report of first-rib stress fractures in an adolescent female swimmer. There is a need for research on the cause, management, and prevention of these injuries as they lead to significant morbidity and critical time away from sport for these aspiring athletes. We aimed to describe first-rib stress fractures as a potential cause for non-specific atraumatic chronic shoulder pain in adolescent swimmers and to discuss the different presentations, unique risk factors, treatment, and potential injury prevention strategies of such fractures. We discussed two such cases which were successfully treated with activity modification with restriction of all overhead activity, gradually progressive physical therapy and a return to swimming protocol. First-rib stress fractures can vary in presentation and should be in the differential diagnosis in adolescent swimmers with chronic shoulder pain. These injuries can be successfully managed with rest from overhead activities and physical therapy. Gradual return to competitive swimming can be achieved even with non-union of a first-rib stress fracture. Emphasis on balanced strength training in different muscle groups and proper swimming technique is essential to prevent these injuries.  相似文献   

A comparison of well-peer mentored and non-peer mentored athletes’ perceptions of satisfaction     

Matt D. Hoffmann  Todd M. Loughead 《Journal of sports sciences》2016,34(5):450-458

The purpose of the present study was to compare well-peer mentored and non-peer mentored athletes’ perceptions of satisfaction. A total of 444 intercollegiate athletes (272 well-peer mentored and 172 non-peer mentored) from a variety of sport teams participated in the study. Athletes from both well-peer mentored and non-peer mentored groups reported their satisfaction levels using the Athlete Satisfaction Questionnaire. The results of a MANOVA and follow-up post hoc ANOVAs showed that well-peer mentored athletes were significantly more satisfied than their non-peer mentored counterparts in terms of individual performance, personal dedication, team task contribution, team social contribution, team integration, ethics, ability utilisation and training and instruction. Overall, the findings suggest that athletes who are well-peer mentored by a teammate perceive higher satisfaction levels with various aspects of their athletic experience than athletes who are not peer mentored by a teammate. Given these positive findings, practitioners (i.e., coaches, sport psychology consultants) should inform athletes on the benefits of peer-to-peer mentoring. The practical implications of the results and strategies to promote peer athlete mentoring relationships in sport are highlighted.  相似文献   

An Evolution of the Migration of Taiwanese Female Basketball Players: From the ‘American Dream’ to the ‘Chinese Dream’     

Ren-Shiang Jiang  Ping-Chao Lee 《国际体育史杂志》2016,33(18):2253-2270

Abstract

This paper explores the migration of female basketball players from Taiwan to China. Governance theory is adopted as the framework in this study to analyze the phenomenon of players’ migration and to understand how it was shaped over the years. The empirical work draws on a qualitative approach, which is based on a review of documentary materials and semi-structured interviews; coding and analysis were undertaken with a content analysis approach in order to investigate the decision-making processes and their consequences for the players’ migration. The feature of systematic governance for the development of women’s basketball has been revealed in this study. Stakeholders with personal interests caused the downturn of women’s basketball development in Taiwan, and it eventually led to the players’ migration abroad. Through the lens of governance theory, it has been revealed that a number of factors – namely, political, financial, personal, socio-economic, and cultural – all intertwine with one another dynamically to influence the female players’ decision to move abroad. This finding broadens the scope for the research of Taiwanese athletes’ migration to China, extending the focus from only business or industry to other aspects, thereby highlighting the fact that the subject is more complex than previously understood.  相似文献
