ABSTRACT We performed a randomized, controlled trial to analyse the effects of resistance training (RT) on cognitive and physical function among older adults. Fifty participants (mean age 67 years, ~60% woman) were randomly assigned to an RT program or a control group. Participants allocated to RT performed three sets of 10-15RM in nine exercises, three times per week, for 12-weeks. Control group did not perform any exercise. Variables included cognitive (global and executive function) and physical function (gait, mobility and strength) outcomes. At completion of the intervention, RT was shown to have significantly mitigated the drop in selective attention and conflict resolution performance (Stroop test: -494.6; 95%CI: -883.1; ?106.1) and promoted a significant improvement in working memory (digit span forward: -0.6; 95%CI: ?1.0; ?0.1 and forward minus backward: -0.9; 95% CI: ?1.6; ?0.2) and verbal fluency (animal naming: +1.4, 95%CI 0.3, 2.5). No significant between-group differences were observed for other cognitive outcomes. Regarding physical function, at completion of the intervention, the RT group demonstrated improved fast-pace gait performance (?0.3; 95% CI: ?0.6; ?0.0) and 1-RM (+21.4 kg; 95%CI: 16.6; 26.2). No significant between-group differences were observed for other mobility-related outcomes. In conclusion, RT improves cognitive and physical function of older adults. 相似文献

Self‐efficacy pertains to individuals’ belief about their capability to accomplish a task; consequently, school counselors’ positive self‐efficacy is a theoretically based prerequisite for their facilitation of school‐based interventions. In addition, school counselor‐led interventions and comprehensive, developmenta l guidance programs benefit students’ personal social, academic, and career development. Therefore, this investigation examined the contribution of practicing school counselors’ (N = 693) self‐efficacy in relation to the frequency of their programmatic service delivery. The findings indicate that participants’ self‐efficacy scores contributed to the frequency of their programmatic service delivery (48% of the variance explained). Implications for school counselors, supervisors, and educational researchers are discussed. 相似文献

This paper provides a history of academic development by examining how a South African institution coped with the potent social forces confronting it before the collapse of apartheid. Theoretically, it draws on the framework of Pierre Bourdieu and engages with a paper written a decade ago by Naidoo, who also used Bourdieu to understand institutional change in South Africa in the late 1980s. Through contrasting the habitus of two professors, it is argued that academic development helps to preserve the autonomy of the university field by refracting forces impinging on it from the economic and political realms. 相似文献
