不同海拔地区世居人口登山前后机体指标变化研究     

王纯  王杰  李磊  旺加  群增 《成都体育学院学报》2010,36(3)

以藏族世居人群80人,成都平原人群117人,共197人为研究对象.对入选对象进行一次登山运动,在登山前和登山后即刻测试生理生化指标以及免疫指标等,系统考察随海拔高度递增,人体身体机能的变化情况.结果显示:高原地区世代居住人群相对于平原地区世代居住人群有氧运动能力更有优势、对大运动量的体力负荷有更好的耐受力;但免疫机能略有下降;适宜高度的登山运动能有效降低心血管疾病的发病率,是一项值得推广的全民健身运动项目.  相似文献

关于强正则环的一些研究     

崔顺 《滁州学院学报》2009,11(2)

利用ZC-环和自-内射环的性质来刻画强正则环.证明了下列结果:1设R是ZC-环,下列条件等价:(1)R是强正则环;(2)R的每一个极大本质左理想是GP-内射的;(3)R中存在一个忠实左R-模K,使得当k∈K且l(k)本质时,l(k)是GP-内射的.2设R是ELT-环,且对于R的每一个本质左理想M,[R/M]R是平坦模,R的每一个补左理想是GW-理想,如果R是左MI-环,那么R是左自-内射强正则环.  相似文献

Comparison of the prevalence and treatment of hypertension in two populations in the United States: Masters swimmers versus the NHANES population     

Sally K. Guthrie  Steven R. Erickson  Matthew S. Lau 《Journal of sports sciences》2013,31(9):930-935

Abstract

This research compares the prevalence of hypertension in a group of adult masters swimmers with an age and sex matched cohort from the 2008 NHANES (National Health and Nutrition Examination Survey), used to represent the general population in the United States. Masters swimmer data were obtained from a one-time survey of all United States Masters Swimming (USMS) members. Both datasets included demographics, drug therapy, diseases and health status. Characteristics of swimming sessions as well as perceptions of impact of medications on exercise were also collected from the USMS respondents. Of 1346 completed surveys from USMS respondents, 15.8% self-identified as having hypertension while 36.2% participants in the NHANES survey suffered from hypertension (P < 0.001). The two groups were well matched for age and gender but the USMS group was primarily Caucasian, higher income, higher education, and reported higher health status. In the USMS group, not only was hypertension less prevalent but those who suffered from hypertension took fewer medications (P = 0.04) to manage their hypertension than in the NHANES group. Additionally, The USMS group suffering from hypertension considered themselves healthier (P < 0.001) than the NHANES group.  相似文献

Relationships between different instructional approaches and students' Classical Chinese reading comprehension and motivation     

Kit‐ling Lau 《Journal of Research in Reading》2019,42(3-4):523-540

Previous studies comparing teacher‐centred (TC) and learner‐centred (LC) instruction have presented a mixed picture of the effectiveness of these two instructional approaches. By examining the effectiveness of different types of instruction on students' Classical Chinese (CC) reading comprehension and motivation, this study aims to contribute to instructional research by elucidating the positive and negative aspects of TC and LC instruction when they are applied in the context of teaching CC reading. A total of 454 Secondary 4 students between the ages of 15 and 17 years agreed to participate in this study on a voluntary basis. They completed a CC reading comprehension test and a questionnaire that measured their CC reading motivation and perceived CC reading instruction. Relationships between students' perceived CC reading instruction, reading motivation and reading comprehension were examined by correlation and path analyses. The findings of the correlation analyses indicated that traditional TC instruction positively and significantly correlated with students' CC reading performance and extrinsic motivation. Motivating tasks, one type of LC instruction, positively and significantly correlated with all types of motivation but did not significantly correlate with CC reading performance. In the path analysis, TC instruction exhibited a significant positive effect on reading comprehension, whereas motivating tasks continued to exhibit a significant positive effect on intrinsic motivation after the effect of the examined schools' achievement level was controlled for. The findings highlight the essential role of teachers in instructing students who are weak in particular subjects. Instead of viewing TC and LC instruction as two contradictory approaches, the findings indicate that a combined approach of TC and LC instruction can more effectively facilitate students' learning in a difficult school subject.  相似文献
