The benefits of ethnic activity group participation on older immigrant well-being and host country adjustment     

《Int J Intercult Relat》2020

Drawing on acculturation and social identity literatures, the present research extends on initial work on social group connectedness among older immigrants to examine in a quasi-experimental study the well-being benefits of participating in heritage culture groups. Older immigrant clients (N = 66) of six aged-care agencies in Australia were given diary booklets in which to complete a set of measures on selected days when they did or did not attend the agencies’ heritage culture group activities, over a 2-month period. Results showed that heritage group participation reduced loneliness and increased well-being. Future research should replicate and extend these findings to assist our understanding of how heritage culture group participation aids first-generation older immigrants with aging successfully in a foreign land.  相似文献

松果腺切除对长期游泳12月龄小鼠肝脏某些抗氧化物质的影响     

熊开宇  赵峰 《北京体育大学学报》2003,26(1):40-42

为了解长期游泳运动老龄小鼠肝脏抗氧化能力的增强与松果腺释放褪黑素的关系,观察了在运动抗衰老机制中褪黑素的作用。结果表明:1)雄性非手术组中GSH-px、SOD活性仅在60min游泳+3%负荷组中明显高于手术同负荷组。雌性小鼠,非手术60min组GSH-px、SOD活性升高,与手术同负荷组相比也有显著差异(P<0.001)。而在60min+3%负荷组,手术组高于非手术组(P<0.05)。2)GSH的表现各组之间差异很大,同负荷组间比较,GSH-px高的组则GSH较低;若GSH-px低则GSH较高。表明长期运动训练使机体抗氧化能力增加,交感神经兴奋性升高刺激松果腺内褪黑素的合成和释放,对GSH-px和SOD的活性有一定作用;如果运动负荷不当,会对松果腺机能产生抑制,对机体抗氧化能力产生负面影响。  相似文献   

太极拳对老年人NK细胞的影响   总被引：14，自引：0，他引：14  

王晓军 《北京体育大学学报》2004,27(5):644-645

人类进入老龄化社会,对衰老机制的研究越来越引起人们的重视.许多研究表明,运动是延缓机体衰老的有效手段之一.通过城镇老年妇女(55～65岁)每天习练太极拳,观察太极拳对老年人NK细胞的影响.结果发现:经过6个月的太极拳练习,老年人血液中NK细胞的含量增加;一次性太极拳练习,可明显提高血液NK细胞的百分含量,表明太极拳运动可能提高机体的免疫机能,增强老年人抗疾病的能力.  相似文献

AI赋能公共图书馆适老化阅读服务研究--以杭州市为例     

李熠煜  朱彤 《新世纪图书馆》2022,(1)

杭州市图书馆运用人工智能等技术,在中心馆-总分馆体系下构建了全市共享的图书馆适老化服务,为老年人在数字环境下提供阅读服务。通过对杭州市公共图书馆的自助转借系统、无障碍服务和设施开发、数字服务平台、“悦借”网络渠道、多元服务方式的分析,肯定了AI赋能下杭州市公共图书馆适老化阅读服务的成效。同时指出,杭图的适老化服务存在对老年人心理层面的关注不够,高层次智慧馆员缺乏等不足。有效提升图书馆适老化服务需要满足老年读者的需求,利用智能设备提高服务效能,加强老年人阅读素养。  相似文献   

政府与公共图书馆——关于图书馆制度的一种规范分析   总被引：21，自引：1，他引：21

公共图书馆是一种典型的公共产品。它的高度正外部性特征,决定了市场提供的非效率性。公共图书馆只能由政府提供,政府必须履行公共图书馆投资主体的责任。为解决公共图书馆的拥挤性和地域性问题,政府必须承担普及公共图书馆的责任,并提供投资保障。图4。参考文献9。  相似文献   

Maximal heart rate declines linearly with age independent of cardiorespiratory fitness levels     

Cemal Ozemek  Mitchell H. Whaley  W. Holmes Finch  Leonard A. Kaminsky 《European Journal of Sport Science》2017,17(5):563-570

There have been many conflicting observations between the linear or curvilinear decline in maximal heart rate (HR_max) with age. The aim of this study was to determine if linear or curvilinear equations would better describe the decline in HR_max with age in individuals of differing cardiorespiratory fitness (CRF) levels. Treadmill cardiopulmonary exercise test (CPX) results from participants (1510 men and 1134 women; 18–76 years) free of overt cardiovascular disease were retrospectively examined using cross-sectional and longitudinal study designs. Participants completing ≥2 CPX with ≥1 year between test dates were included in the longitudinal analysis (325 men and 150 women). Linear and quadratic regressions were applied to age and HR_max for the whole cohort and respective CRF groups (high, moderate, and low, relative to age and gender normative values). To test for differences among linear, quadratic, and polynomial equations, the change in R² (cross-sectional analysis) and Bayesian information criterion (BIC) (longitudinal analysis) from the linear to the more complex models were calculated. The quadratic or polynomial regression in the cross-sectional analysis, marginally improved the variance in HR_max explained by age compared to the linear regression for the whole cohort (0.2%), moderate fit group (0.3%), and low fit group (0.8%). With no improvements in the high fit group. BIC did not improve for any CRF category in the longitudinal analysis. In conclusion, the minimal differences among linear, quadratic, and polynomial equations in the respective CRF groups, emphasizes the use of linear prediction equations to estimate HR_max.  相似文献

ABSTRACT

This research adapted the Life Skills Scale for Sport (LSSS) into Portuguese and provided evidence for its construct validity. Study 1 included four translators and five academics who developed a Portuguese version of the LSSS (P-LSSS). During this study, evidence for the content and substantive aspects of construct validity was provided using an expert panel and 25 sports participants. Study 2 included 413 participants that completed the P-LSSS. Within this study, evidence for the structural aspect of construct validity was provided via factor analyses. Study 3 included 134 participants who completed the P-LSSS and a measure of motivation. This study provided evidence for the external aspect of construct validity, with results showing more self-determined motivation had positive relationships with participant’s life skills development. Overall, our findings provided evidence for the construct validity of P-LSSS scores. Researchers and practitioners can use the P-LSSS to assess life skills development within sports participants.  相似文献
