不同体育锻炼项目对大学生心理韧性的影响

采用问卷法对承德某高校学生进行调查,对选修不同体育锻炼项目课程学生的心理韧性情况进行统计分析,结果表明：选修篮球、足球、现代舞项目学生的心理韧性要显著优于选修太极项目的学生;选修对抗性项目学生在心理韧性显著优于非对抗性项目;课余锻炼量较大的学生心理韧性最好。     

高校教师亚健康状况分析与对策研究

为了解我校教师的亚健康状况,采用问卷法和统计法调查研究我校教师的亚健康与运动现状。结果表明,亚健康的症状和发生机制与机体运动不足有关。因此加强亚健康与运动的宣传教育,提高教师的兴趣和热情,让更多的人进行体育锻炼,是预防和控制亚健康,恢复健康的最佳途径。

Virtual Mechatronic/Robotic laboratory – A step further in distance learning

The implementation of the distance learning and e-learning in technical disciplines (like Mechanical and Electrical Engineering) is still far behind the grown practice in narrative disciplines (like Economy, management, etc.). This comes out from the fact that education in technical disciplines inevitably involves laboratory exercises and this fact drastically increases the complexity of a potential e-learning system. New approach and new specific knowledge are needed to develop such a system. We expect to meet the requirements of distance learning by developing the software-based laboratory exercises, i.e., a virtual laboratory. To fully substitute a physical system like laboratory equipment, one must emulate its full dynamics. The mathematical model in the form of differential equations will be applied to calculate dynamics and provide the data that would otherwise be measured on a physical system – this means simulation.     

A service recovery method to enhance customer satisfaction with a case study of motion sport game

Service recovery is a concept that involves regaining customer satisfaction and loyalty. Although existing studies have addressed its importance, few service recovery methodologies have been developed. Thus, there is a need to develop a systematic framework that can first detect customer status and then provide appropriate recovery recommendations to ensure customer satisfaction. This study develops such a framework in relation to an individual health maintenance practice. While regular moderate exercise is known to promote good health and help prevent disease, the lack of exercise remains a crucial health issue. This study presents a logistic regression model that uses both physiological data (heart rate and blood pressure) and psychological data (ratings of perceived exertion) to detect the effectiveness of an individual's exercise and to provide sports‐related service recovery suggestions as needed. To implement and assess this service recovery model, the use of a motion gaming system is proposed.     

南京市高职教师身体健康与体育锻炼研究

通过对5所高职院校教师的体育锻炼情况及健康状况的调查研究,得出高职院校教师整体缺乏体育锻炼,身体健康状况堪忧的现状。经分析认为造成这一状况的主要原因为高职院校缺乏良好的体育文化氛围,教师体育锻炼没有完善的规章制度,运动场地器材匮乏以及其他制约因素多。并提出具体的改进方法。

Metabolic and cardiovascular responses to exercise with caffeine

The effect of caffeine on circulation and metabolism was studied during a discontinuous maximal oxygen uptake (VO₂ max) test on a bicycle ergometer. Eight male subjects were chosen for their minimal use of caffeine of which six normally did not ingest caffeinated beverages. Two caffeinated and two decaffeinated (control) trials were administered to each subject following double-blind and counterbalanced testing procedures. One hour before exercise, subjects ingested decaffeinated coffee with or without 350 mg of caffeine anhydrous added. Cardiac output (Q) was measured by a C0₂ rebreathing technique. Compared to control trials, caffeine increased the VO₂ max by an average of 140ml min?¹ (p <0-0·5)l. In addition, during caffeine trials, the average maximal heart rate (HR max) was elevated by 5 beats min^?1 (p<0·01). There were no other statistically significant changes in metabolic (VO₂ and R) and cardiovascular (Q, HR, SV and (a-v) 0₂ diff) variables during either submaximal or maximal exercise. Performance, as measured by total exercise time on the VO₂ max test, was not significantly different (p>0·05). It was concluded that caffeine has a small physiological but a statistically significant effect on VQ₂ max and HR max. During submaximal exercise, caffeine did not significantly effect the cardiovascular system.
