目的：锻炼与针刺组合对退行性膝关节炎微循环血流灌注量的影响。方法：研究对象40例随机分为2组，分别是针刺组（单纯针刺）和锻炼组（站桩与针刺组合），对其实验前后疼痛程度（VAS）、微循环血流灌注量（MBPU）及皮肤温度的变化进行检测分析。结果：两组实验后，VAS评分明显降低（P<0.01），锻炼组优于针刺组（P<0.05）；MBPU降低（P<0.01），锻炼组优于针刺组（P<0.05）；局部温度明显提高（P<0.05）。结论：锻炼与针刺组合可以明显缓解退行性膝关节炎的疼痛症状，降低局部微循环血流灌注量，提高皮肤温度；优于单纯针刺疗法。  相似文献   

Childhood Physical Fitness and Performance as Predictors of High School Sport Participation

ABSTRACT

Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school.  相似文献   

Audience management,online turbulence and lurking in social networking services: A transactional process of stress perspective     

《International Journal of Information Management》2021

In social networking services (SNSs), users’ unclear understanding of the large and invisible audience increases the chances of online turbulence, which is a key source of SNS-induced stress. This growing phenomenon has gained increasing attention in academia and industry due to the undesirable consequences for users and SNS platforms. In this study, we draw from the transactional model of stress to examine how audience management strategies impact online turbulence and lead to neglected unintended audience concern and lurking. We also investigate the role of self-monitoring as a stress inhibitor. We test our model with data collected from 301 SNS users. The results show that the four types of audience management strategies have different effects on online turbulence, which significantly impacts neglected unintended audience concern especially when users have high self-monitoring skills. We believe that this work contributes, both from scientific and practical standpoints, to the understanding of the interventions and stressful responses of online turbulence in SNSs.  相似文献

Effects of an aerobic fitness test on short- and long-term memory in elementary-aged children

ABSTRACT

Meta-analytic evidence supports that exercise has benefits for short-term memory (STM) and long-term memory (LTM). However, only three studies with children have tested the differential effects of exercise on STM and LTM. The purpose of this study was to examine the effects of an aerobic fitness test on STM and LTM and to consider the moderating effects of grade level. Children (7–13 years of age) were randomly assigned to either perform an aerobic fitness test before (exercise prior) or after (exercise post) performing the Rey Auditory Verbal Learning Test (RAVLT) to assess memory. Memory was tested again after approximately 24 hours. There were significant differences in memory performance as a function of grade with 4^th and 6^th graders consistently outperforming 2^nd graders. For learning, Day 1 Retention, 24-hr recall, and Day 2 Retention, the exercise prior group performed better than the exercise post group. It is concluded that an aerobic fitness test performed prior to a declarative memory test benefits LTM as compared to when the aerobic fitness test is performed after the memory test.  相似文献

Tennis superstars: The relationship between star status and demand for tickets     

《Sport Management Review》2020,23(2):330-347

Akin to other sports, professional tennis is urged to adopt a consumer-centred strategy and understand the influence of the star status of elite players on demand for its core product. Measuring the impact that tennis players have on demand for match attendance remains a key element towards achieving that goal. Using data from the Australian Open ticket sales, the authors demonstrate how individual players have influenced stadium attendance at the Grand Slam. Findings indicate that some players are associated with a strong positive impact on demand for tickets, above and beyond their performance ratings, reflecting their value to the Australian Open. The authors discuss how this star status can be used to inform business decisions related to tournament management, match scheduling, and determining player appearance fees, to ultimately drive better commercial outcomes and deliver a world-class sporting event. The findings have implications for tournament organisers, player managers and those that market player activities.  相似文献   

Chinese university EFL teachers’ beliefs and practices of classroom writing assessment     

《Studies in Educational Evaluation》2020

This study investigates the extent to which university teachers’ beliefs about classroom writing assessment are congruent with their self-perceived practices in English-as-a-foreign-language (EFL) contexts, and what factors contribute to belief-practice inconsistencies. Drawing on data from a survey of 136 Chinese university EFL writing teachers and ten teacher interviews, results showed a degree of belief-practice alignment regarding assessment for learning (AfL) practices that make learning explicit, but belief-practice discrepancies were more salient. AfL practices that empower students to take responsibility in writing assessment were perceived to be more important than assessment of learning practices; however, the reverse was found in teachers’ practice. Impacts of micro-level factors including assessment training, teaching experience, student attributes, meso-level school factors, and macro-level assessment culture are discussed, and implications are drawn.  相似文献   

场域视阈下乡村体育教师专业发展的“内卷化”困境与突围     

武旭  乔玉成 《南京体育学院学报(社会科学版)》2021,35(6)

乡村体育教师的专业发展事关乡村体育教育全局,是乡村教育的重要支持内容,也是当前体育教育的研究热点之一。运用问卷调查法和逻辑分析法,以场域理论为视角,以参加S省Z市“国培计划(2020)”乡村学校体育教师技能提升培训班的学员为调查对象,了解乡村体育教师专业发展困境,探究其原因和对策。结果显示,现阶段乡村体育教师的专业发展不容乐观,陷入了“没有发展的增长”的“内卷化”困境。场域边界限制、资本累积束缚和惯习冲突是其主要原因。提出破解乡村体育教师专业发展“内卷化”困境的对策,应从构建合作场域、完善要素保障机制及推动行动惯习转换等方面入手,打造有利于乡村体育教师完成资本累积、惯习转换的场域环境。  相似文献
