新世纪发展体育经济的战略思考

21世纪是信息时代,更是经济与体育全球化大比拼的时代。体育带动经济发展和经济推动体育进步,二者相互依存、同进同退,成为世界共识。为此,本文从发展经济学的角度,提出了"体育经济"的战略观点,并就体育与经济的紧密关系和发展体育经济的战略构思,进行了抛砖引玉式的分析。     

不同锻炼方式对老年人心理健康和心肺功能影响的探讨

通过对不同运动项目组与不参加体育活动组老年人心理衰老指数、心功能、肺通气功能等指标的比较,探讨不同锻炼方式(门球,太极拳和快走、慢跑锻炼)对老年人心理健康和心肺功能的影响.结果表明:各锻炼组心衰指数均优于不锻炼的老年对照组,但各锻炼组间无显著差别.快走、慢跑组心功能、通气功能明显优于门球和太极拳组.可见采取不同的锻炼方式对老年人心理健康和心肺功能的影响不同,老年人可根据自身实际选择不同的锻炼方式.

我国体育服务业低度均衡形成因素分析

从制度经济学理论视角研究出发,认为当前我国体育服务业发展客观上存在低度均衡现象,信息不对称、传统习俗影响等是体育服务业低度均衡产生或使低度均衡加剧的重要因素.供求均衡点过低不仅直接导致高收入阶层对体育消费增长的带动性不能实现,并且致使大量潜在的体育消费群体得不到有效释放,新的经济增长点难以形成.促使我国体育服务业走出低度均衡困境的途径是实现制度创新和加强政策引导.     

Correlations between serum and salivary hormonal concentrations in response to resistance exercise

The aim of present study was to examine the relationships between serum and salivary values of free testosterone, dehydroepiandrosterone, and cortisol before and after a session of resistance exercise. Twenty-eight healthy men (mean age 40 years, s = 4) participated in the present study. Serum and salivary samples were collected at rest and after a multiple-sets resistance exercise protocol, of approximately 25 minutes duration. Concentrations of free testosterone, dehydroepiandrosterone, and cortisol were measured using radioimmunoassay kits. No significant correlation was observed between serum free testosterone and salivary testosterone (r = 0.22 to 0.26, P > 0.05). Serum cortisol was significantly correlated with salivary cortisol before (r = 0.52, P = 0.005) and after (r = 0.62, P = 0.001) the exercise protocol. Serum and salivary concentrations of dehydroepiandrosterone were significantly correlated before (r = 0.68, P < 0.001) and after (r = 0.7, P < 0.001) exercise. The results of the present study suggest that even under exercise conditions, the salivary values of cortisol and dehydroepiandrosterone can reflect the behaviour of these hormones in blood. However, further studies are necessary to verify if salivary testosterone reflects the behaviour of serum free testosterone during resistance exercise.     

现代背越式跳高技术训练探析——从运动学视角论技术整合因素的效应

采用文献资料法、生物力学方法、数理统计法和数理分析法分别从助跑速度、摆动效果、蹬伸实效性三个方面对中外优秀男子跳高运动员起跳技术的运动学特征进行深入的比较分析,发现起跳的过程中垂直速度偏小和摆动腿角度角速度慢是导致我国跳高成绩落后的原因.认为决定跳高成绩关键因素是起跳时的垂直速度,如何充分利用助跑速度,提高起跳效果,是当前背越式跳高技术训练的重点.     

Guideposts and Roadblocks to the Career-Long Scholarly Engagement of Physical Education Teacher Education Faculty

Purpose: Scholarship is essential for the growth and development of the physical education field. Over time, scholarship expectations have changed, forcing faculty members to alter time spent for research, teaching, and service. Social-cognitive career theory (SCCT) presents a model for understanding performance and persistence in an occupational environment. The interconnected aspects of SCCT have different emphasis related to self-efficacy, outcome expectations, or personal goals pursuit. This study explored physical education teacher education (PETE) faculty members’ continuing engagement in scholarly activity through SCCT. Method: Data collection included interviews with 9 senior PETE faculty members who met the criteria for “productive scholars over time.” Curriculum vitae were collected to verify productivity. Results: Data analysis revealed guidepost themes that included collaborating, finding balance, defining a research process, and maintaining a strong work ethic. Roadblocks encountered included other obligations and lack of support for research. Conclusions: Participants demonstrated strong self-efficacy; held high, positive expectations for success; and set very specific, clear, and deliberate goals. Participant behavior was moderated by their personal attributes (capacity to build relationships, set goals, and maintain interest and passion) and was tempered by the environments in which they worked. Fostering similar behaviors has the potential to guide future and current PETE faculty members in creating supportive and encouraging atmospheres for sustained productivity. The lack of literature relating to this topic warrants the need for more research exploring the influential factors and benefits gained from sustained scholarly productivity over time for PETE faculty members.
