Improving cognitive and physical function through 12-weeks of resistance training in older adults: Randomized controlled trial

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.     

The Hand of God,the Hand of the Devil: a sociological interpretation of Maradona’s hand goal

Based on the moral problem of Maradona’s goal, known as the ‘Hand of God’, this essay presents a theoretical discussion using the perspective of figurational sociology of how game rules and moral rules are related. It does not aim to solve the moral dispute occasioned by actions like the ‘Hand of God’, but concentrates on a much more limited discussion (appealing to far fewer people) in which we strive to reach a proper sociological understanding. Indeed, we believe that the ‘Hand of God’ is a paradigmatic event for sociological reasoning. This is not to claim that sociology can give any final answers, but to suggest the opposite, namely that an understanding of the value of ‘hand goals’ can be very important for understanding the limits of sociological reason.     

Effects of cold water immersion on the recovery of physical performance and muscle damage following a one-off soccer match

The aim of this study was to assess the effects of a single session of cold or thermoneutral water immersion after a one-off match on muscular dysfunction and damage in soccer players. Twenty-male soccer players completed one match and were randomly divided into cryotherapy (10 min cold water immersion, 10°C, n = 10) and thermoneutral (10 min thermoneutral water immersion, 35°C, n = 10) groups. Muscle damage (creatine kinase, myoglobin), inflammation (C-reactive protein), neuromuscular function (jump and sprint abilities and maximal isometric quadriceps strength), and delayed-onset muscle soreness were evaluated before, within 30 min of the end, and 24 and 48 h after the match. After the match, the players in both groups showed increased plasma creatine kinase activity (30 min, 24 h, 48 h), myoglobin (30 min) and C-reactive protein (30 min, 24 h) concentrations. Peak jump ability and maximal strength were decreased and delayed-onset muscle soreness increased in both groups. However, differential alterations were observed between thermoneutral water and cold water immersion groups in creatine kinase (30 min, 24 h, 48 h), myoglobin (30 min), C-reactive protein (30 min, 24 h, 48 h), quadriceps strength (24 h), and quadriceps (24 h), calf (24 h) and adductor (30 min) delayed-onset muscle soreness. The results suggest that cold water immersion immediately after a one-off soccer match reduces muscle damage and discomfort, possibly contributing to a faster recovery of neuromuscular function.     

Curriculum stasis: the disconnect between music and technology in the Australian curriculum

Technology is a dominant mediating factor impacting on current human behaviour and social change, which both acts on and is acted upon by other phenomena. This changing social landscape, along with new expectations and requirements, drives our educational priorities and curriculum agenda. There is no denying the prevalence of technology found in the statements and guidelines of the national Australian Curriculum. Further, the National Review of School Music Education identified the importance of technology in school music education in 2005. The curriculum guidelines illustrate an understanding of technology in Music and the Arts that is both vague and limiting. In 2015 we are at a point of curriculum stasis, an equilibrium that highlights a disconnect between music, technology and Australian music education. This article investigates current secondary school Years 7–10 (ages 11–15 years) Music and Arts curriculum statements concerning the use of technology and compares this to the general capability information and computer technology (ICT) curricula. There is wide recognition that digital technology is essential in teaching and learning, but this is not reflected in contemporary Australian Arts and Music curricula.     

Preschool children's exposure to story grammar elements during parent–child book reading

Twenty‐three preschool‐age children, 3;6 (years; months) to 4;1, were videotaped separately with their mothers and fathers while each mother and father read a different unfamiliar storybook to them. The text from the unfamiliar storybooks was parsed and coded into story grammar elements and all parental extratextual utterances were transcribed and coded for (1) their relationship to the story grammar elements found within the storybook, and (2) the natural strategies parents used to direct their children's attention to these elements. Children's overall exposure to story grammar elements during book reading was also explored for its relationship to their language abilities. Results indicated that parents focused significantly more on the resolution, attempt, and consequence compared to the initiating event and plan, and most frequently used the text and pictures as strategies for recruiting their children's attention to the story grammar elements within the book. In addition, the frequency of parental utterances related to story grammar elements was negatively correlated with children's language abilities. This study did not examine the complexity or depth of parental utterances related to story grammar elements. These findings provide initial evidence that children may derive their understanding of story grammar at least in part through their parents' extratextual discussions during parent–child book reading.     

The policy problem: the National Disability Insurance Scheme (NDIS) and implications for access to education

This paper explores the changing terrain of disability support policy in Australia. Drawing on a critical disability framework of policy sociology, the paper considers the policy problem of access to education for people with disabilities under recent reform by means of the National Disability Insurance Scheme (NDIS), which commenced full roll-out across the country from July 2016. The paper reviews NDIS reports, legislation and associated literature to consider how eligibility to scheme participation and education services are shaped, and how education is positioned in the development and implementation of the NDIS. The analysis highlights tensions that exist for people with disabilities and their families who both access the scheme and who might draw on its provision to support their education, because of the way the policy is oriented towards pathological categorisation, standardised outcomes and service delineation rather than integrated support and informed involvement. The paper concludes by arguing that despite the policy priority across Organisation for Economic Co-operation and Development countries of increasing lifelong learning opportunities, fragmented NDIS policy in Australia prevents people with disabilities from achieving this ideal.     

The Role of Parents and Community in the Education of the Japanese Child

In Japan, there has been an increased concern about family and community participation in the childs education. Traditionally, the role of parents and community in Japan has been one of support and less one of active involvement in school learning. Since the government commenced education reforms in the last quarter of the 20th century, a more active role for parents and the community in education has been encouraged. These reforms have been inspired by the need to tackle various problems that had arisen, such as the perceived harmful elements of societys preoccupation with academic achievement and the problematic behavior of young people. In this paper, the following issues are examined: (1) education policy and reform measures with regard to parent and community involvement in the childs education; (2) the state of parent and community involvement at the eve of the 20th century.     

Elementary Teacher’s Conceptions of Inquiry Teaching: Messages for Teacher Development

This study explored practicing elementary school teacher’s conceptions of teaching in ways that foster inquiry-based learning in the science curriculum (inquiry teaching). The advocacy for inquiry-based learning in contemporary curricula assumes the principle that students learn in their own way by drawing on direct experience fostered by the teacher. That students should be able to discover answers themselves through active engagement with new experiences was central to the thinking of eminent educators such as Pestalozzi, Dewey and Montessori. However, even after many years of research and practice, inquiry learning as a referent for teaching still struggles to find expression in the average teachers’ pedagogy. This study drew on interview data from 20 elementary teachers. A phenomenographic analysis revealed three conceptions of teaching for inquiry learning in science in the elementary years of schooling: (a) The Experience-centered conception where teachers focused on providing interesting sensory experiences to students; (b) The Problem-centered conception where teachers focused on engaging students with challenging problems; and (c) The Question-centered conception where teachers focused on helping students to ask and answer their own questions. Understanding teachers’ conceptions has implications for both the enactment of inquiry teaching in the classroom as well as the uptake of new teaching behaviors during professional development, with enhanced outcomes for engaging students in Science.
