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   

Ghosts as rhetorical devices in children's fiction     

Judith Armstrong 《Children‘s Literature in Education》1978,9(2):59-66

The relationship of past and present and the linking of characters through time and place are themes that underlie the work of many writers for children. This article considers the use of the Ghost as a literary device to allow the exploration of what is, what has been, and what might have been, particularly in the 1973 Carnegie Medal Winner,The Ghost of Thomas Kempe, by Penelope Lively.Judith Armstrong was brought up in Lancashire. She has travelled widely, and taught young children in England and Ethiopia. She is currently working on themes associated with the supernatural in children's books.  相似文献   

Submaximal exercise and maturation in 12-year-olds     

Armstrong N  Welsman JR  Kirby BJ 《Journal of sports sciences》1999,17(2):107-114

The aim of this study was to examine the maturation responses of young people to submaximal treadmill exercise. Body mass was controlled using both the conventional ratio standard and allometric modelling. Ninety-seven boys and 97 girls with a mean age of 12.2 years completed a discontinuous, incremental exercise test to voluntary exhaustion. We measured peak oxygen uptake (VO2peak) and VO2 when running at 8, 9 and 10 km x h(-1). Sexual maturation was assessed visually using Tanner's indices of pubic hair. Peak VO2 was significantly higher in boys (P<0.001); this was still the case when the influence of body mass was covaried out. During submaximal exercise, no significant differences in absolute VO2 were observed between the sexes (P>0.05); however, values of VO2, expressed both in ratio with body mass and adjusted for body mass using allometry, were significantly greater in boys than in girls (P<0.001). For absolute VO2, significant main effects (P<0.05) were seen for maturity at each exercise stage. With the influence of body mass controlled using either the ratio standard or allometry, no significant main effects (P>0.05) for maturity were observed. Our results indicate that boys are less economical than girls while running at 8-10 km x h(-1) and that, independently of body mass, maturation does not influence the VO2 response to submaximal exercise.  相似文献

Effects of cooperative vs individualistic learning experiences on interpersonal attraction between learning-disabled and normal-progress elementary school students     

Barbara Armstrong  David W. Johnson  Bruce Balow 《Contemporary educational psychology》1981,6(2):102-109

The effects of cooperative and individualistic learning experiences were compared on (1) interpersonal attraction between nonhandicapped fifth- and sixth-grade elementary school students and learning-disabled peers and (2) achievement. Students participated in a language arts class lasting 90 min a day for 17 days. The results indicate that greater interpersonal attraction between the learning-disabled and normal-progress students and higher achievement resulted in the cooperative than in the competitive condition.  相似文献   

Thinking it through: a study of how pre-service teachers respond to children who present with possible mental health difficulties     

David Armstrong  Deborah Price  Tim Crowley 《Emotional and Behavioural Difficulties》2013,18(4):381-397

Teachers are key professionals in responding to children and adolescents with possible mental health difficulties and who exhibit social, emotional or behavioural difficulties in the classroom. Health and education policy increasingly positions teachers as vital agents in connecting mental health services with affected young people. A growing corpus of research, however, questions practitioners’ capacity to undertake this important role, particularly given the limited space afforded to content around mental health in pre-service teacher education. This paper reports on a qualitative case study, conducted in an Australian context, investigating pre-service teacher responses to five vignettes of young people presenting behaviours indicative of possible mental health difficulties. In light of educator expectations to identify and appropriately respond to mental health difficulties, this study discloses the need for explicit, structured mental health guidance which form a discrete, core ‘knowledge base’ of teacher education. Patterns in data, analysed in light of policy literature, also suggest the value inherent in advocating open-minded, non-judgemental and collegial professional responses. Further research opportunities highlighted include a systematic review of current provision around mental health in pre-service teacher education programmes.  相似文献
