RESUMEN

The risk and prevalence of Type 2 Diabetes (T2D) has dramatically increased over the past decade. The aim of this study was to develop, implement and evaluate a physical activity intervention to improve aerobic and muscular fitness among adults at risk of, or diagnosed with T2D. A 20-week, assessor blinded, parallel-group randomized controlled trial (RCT) was conducted at the University of Newcastle (June-December 2015). Adults were randomized to the intervention (n=42) or wait-list control group (n=42). The theory-based intervention included: Phase 1 (weeks 1-10) integrated group sessions (outdoor physical activity and cognitive mentoring), and the eCoFit smartphone application (app). Phase 2 (weeks 11-20) only included the eCoFit app. Participants were assessed at baseline, 10weeks and 20weeks. Linear mixed models (intention-to-treat) were used to determine group-by-time interactions at 10weeks (primary time-point) and 20weeks for the primary outcomes. Several secondary outcomes were also assessed. After 10weeks, significant group-by-time effects were observed for aerobic fitness (4.5mL/kg/min; 95% CI [1.3, 7.7], d=0.68) and muscular fitness (lower body) (3.4 reps, 95% CI [2.7, 4.2], d=1.45). Intervention effects for secondary outcomes included significant increased physical activity (1330steps/week), improved upper body muscular fitness (5 reps; arm-curl test), improved functionality (-1.8s; timed-up and go test) reduced waist circumference (2.8cm) and systolic blood pressure (-10.4mmHg). After 20weeks, significant effects were observed for lower body muscular fitness and health outcomes. eCoFit is an innovative lifestyle intervention which integrates smartphone technology, social support, and the outdoor environment to improve aerobic and muscular fitness.

RESUMEN

BACKGROUND: Despite the health benefits of regular physical activity, most children are insufficiently active. Schools are ideally placed to promote physical activity; however, many do not provide children with sufficient in-school activity or ensure they have the skills and motivation to be active beyond the school setting. The aim of this project is to modify, scale up and evaluate the effectiveness of an intervention previously shown to be efficacious in improving children's physical activity, fundamental movement skills and cardiorespiratory fitness. The 'Internet-based Professional Learning to help teachers support Activity in Youth' (iPLAY) study will focus largely on online delivery to enhance translational capacity. METHODS/DESIGN: The intervention will be implemented at school and teacher levels, and will include six components: (i) quality physical education and school sport, (ii) classroom movement breaks, (iii) physically active homework, (iv) active playgrounds, (v) community physical activity links and (vi) parent/caregiver engagement. Experienced physical education teachers will deliver professional learning workshops and follow-up, individualized mentoring to primary teachers (i.e., Kindergarten - Year 6). These activities will be supported by online learning and resources. Teachers will then deliver the iPLAY intervention components in their schools. We will evaluate iPLAY in two complementary studies in primary schools across New South Wales (NSW), Australia. A cluster randomized controlled trial (RCT), involving a representative sample of 20 schools within NSW (1:1 allocation at the school level to intervention and attention control conditions), will assess effectiveness and cost-effectiveness at 12 and 24 months. Students' cardiorespiratory fitness will be the primary outcome in this trial. Key secondary outcomes will include students' moderate-to-vigorous physical activity (via accelerometers), fundamental movement skill proficiency, enjoyment of physical education and sport, cognitive control, performance on standardized tests of numeracy and literacy, and cost-effectiveness. A scale-up implementation study guided by the RE-AIM framework will evaluate the reach, effectiveness, adoption, implementation, and maintenance of the intervention when delivered in 160 primary schools in urban and regional areas of NSW. DISCUSSION: This project will provide the evidence and a framework for government to guide physical activity promotion throughout NSW primary schools and a potential model for adoption in other states and countries.

RESUMEN

Numerous studies have identified a positive association between fundamental movement skill (FMS) competency and physical activity in children; however, the causal pathways have not been established. The aim of this study is to determine if changes in FMS competency mediated the effect of the Supporting Children's Outcomes using Rewards, Exercise and Skills (SCORES) intervention on physical activity and cardiorespiratory fitness in children. Eight primary schools (25 classes) and 460 children (aged 8.5 ± 0.6, 54% girls) were randomised to the SCORES intervention or control group for the 12-month study. The outcomes were accelerometer-determined moderate-to-vigorous physical activity (MVPA) and cardiorespiratory fitness. The hypothesised mediators were actual FMS competency and perceived sport competence. Mediation analyses were conducted using multilevel linear analysis in MPlus. From the original sample, 138 (30.0%) and 370 (80.4%) children provided useable physical activity and cardiorespiratory fitness data at post-test assessments. There were significant treatment effects for locomotor skills and overall FMSs. Changes in MVPA were associated with changes in object-control skills, overall FMSs and perceived competence. The overall FMSs had a significant mediating effect on MVPA (AB = 2.09, CI = 0.01-4.55). Overall FMSs (AB = 1.19, CI = 0.002-2.79) and locomotor skills (AB = 0.74, CI = 0.01-1.69) had a significant mediating effect on cardiorespiratory fitness. The results of this study conclude that actual but not perceived movement skill competency mediated the effect of the SCORES intervention on physical activity and cardiorespiratory fitness.

RESUMEN

BACKGROUND: Although previous studies have demonstrated that children with high levels of fundamental movement skill competency are more active throughout the day, little is known regarding children's fundamental movement skill competency and their physical activity during key time periods of the school day (i.e., lunchtime, recess and after-school). The purpose of this study was to examine the associations between fundamental movement skill competency and objectively measured moderate-to-vigorous physical activity (MVPA) throughout the school day among children attending primary schools in low-income communities. METHODS: Eight primary schools from low-income communities and 460 children (8.5 ± 0.6 years, 54% girls) were involved in the study. Children's fundamental movement skill competency (TGMD-2; 6 locomotor and 6 object-control skills), objectively measured physical activity (ActiGraph GT3X and GT3X + accelerometers), height, weight and demographics were assessed. Multilevel linear mixed models were used to assess the cross-sectional associations between fundamental movement skills and MVPA. RESULTS: After adjusting for age, sex, BMI and socio-economic status, locomotor skill competency was positively associated with total (P=0.002, r=0.15) and after-school (P=0.014, r=0.13) MVPA. Object-control skill competency was positively associated with total (P<0.001, r=0.20), lunchtime (P=0.03, r=0.10), recess (P=0.006, r=0.11) and after-school (P=0.022, r=0.13) MVPA. CONCLUSIONS: Object-control skill competency appears to be a better predictor of children's MVPA during school-based physical activity opportunities than locomotor skill competency. Improving fundamental movement skill competency, particularly object-control skills, may contribute to increased levels of children's MVPA throughout the day.

RESUMEN

INTRODUCTION: Type 2 diabetes mellitus (T2DM) is a global public health concern. Aerobic physical activity (PA) and resistance training (RT) play significant roles in the prevention and management of T2DM. The aim of this pilot trial is to determine the preliminary efficacy and confirm feasibility of referral to exercise physiologists, psychologists, and provision of a technology-based behavior change support package to promote aerobic PA and RT in school teachers 'at risk' of or diagnosed with T2DM. RESEARCH DESIGN AND METHODS: The SMART (Support, Motivation and Physical Activity Research for Teachers') Health pilot study will be evaluated using a three-arm randomized controlled trial. The intervention will be guided by Social Cognitive Theory, Health Action Process Approach Model and Cognitive Behavioral Therapy strategies. The participants will be randomly allocated to one of three study groups: Group 1: wait-list control group; Group 2: 5 face-to-face visits with a psychologist and exercise specialist over 3 months; and Group 3: same as Group 2 plus technology-based behavior change support package for an additional 6 months. Assessments will be conducted at baseline, 3-, 9- (primary time-point) and 18-months post-baseline. The primary outcome will be PA measured with pedometers. DISCUSSION: SMART Health is an innovative, multi-component intervention, that integrates referral to exercise specialists, psychologists and provision of a technology-based behavior support package to promote PA and RT in adults diagnosed with T2DM or 'at risk' of T2DM. The findings will be used to guide future PA interventions and to develop effective community-based diabetes prevention and treatment programs.

RESUMEN

INTRODUCTION: The prevalence and risk of Type 2 Diabetes (T2D) has dramatically increased over the past decade. Physical activity (PA) has significant benefits for the treatment and prevention of T2D. The aim of this study is to develop, implement and evaluate a community-based PA intervention to improve aerobic and muscular fitness among adults at risk of, or diagnosed with T2D. RESEARCH DESIGN AND METHODS: The eCoFit pilot intervention will be evaluated using a randomized controlled trial (RCT) design. The 20-week (Phases 1 and 2) multi-component intervention was guided by Social Cognitive Theory, Health Action Process Approach Model, and Cognitive Behavior Therapy strategies. Phase 1 (Weeks 1-10) includes: i) 5 group face-to-face sessions consisting of outdoor training and cognitive mentoring; and ii) the use of the eCoFit smartphone application with a description of where and how to use the outdoor environment to be more physically active. Phase 2 (Weeks 11-20) includes the use of the eCoFit smartphone application only. Assessments are to be conducted at baseline, 10-weeks (primary end-point) and 20-weeks (secondary end-point) post-baseline. Primary outcomes are cardio-respiratory fitness and muscular fitness (lower body). Secondary outcomes include physical, behavioral, mental health and quality of life, and social-cognitive outcomes. DISCUSSION: eCoFit is an innovative, multi-component intervention, which integrates smartphone technology, social support and the outdoor physical environment to promote aerobic and resistance training PA among adults at risk of, or diagnosed with T2D. The findings will be used to guide future interventions and to develop and implement effective community-based prevention programs.

RESUMEN

PURPOSE: Physical activity (PA) declines dramatically during adolescence, and activity levels are consistently lower among children living in low-income communities. Competency in a range of fundamental movement skills (FMS) may serve as a protective factor against the decline in PA typically observed during adolescence. The purpose of this study was to evaluate the effect of a 12-month multicomponent PA and FMS intervention on children attending primary schools in low-income communities. METHODS: The Supporting Children's Outcomes using Rewards, Exercise, and Skills intervention was evaluated using a cluster randomized controlled trial. The sample included 25 classes from eight primary schools located in low-income communities. Participants were 460 children (54.1% girls) age 8.5 ± 0.6 yr. Primary outcomes were objectively measured PA (ActiGraph GT3X and GT3X+ accelerometers), FMS competency (Test of Gross Motor Development 2, six locomotor and six object control skills), and cardiorespiratory fitness (20-m multistage fitness test) assessed at baseline, midprogram (6-months), and at posttest (12 months). Linear mixed models, adjusted for sex, age, body mass index z-score, socioeconomic status, ethnicity, and school class as a random factor, were used to assess the effect of the intervention. RESULTS: At midprogram, there were no significant intervention effects for any of the outcomes. At posttest (study's primary time point), there were intervention effects for daily moderate-to-vigorous PA (MVPA) (adjusted mean difference, 12.7 min·d of MVPA; 95% confidence interval (CI), 5.0-20.5), overall FMS competency (4.9 units; 95% CI, -0.04 to 9.8), and cardiorespiratory fitness (5.4 laps; 95% CI, 2.3-8.6). CONCLUSIONS: A school-based multicomponent PA and FMS intervention maintained daily MVPA, improved overall FMS competency, and increased cardiorespiratory fitness among children attending primary schools in low-income communities.

RESUMEN

BACKGROUND: Fundamental movement skill (FMS) proficiency is positively associated with physical activity and fitness levels. The objective of this study was to systematically review evidence for the benefits of FMS interventions targeting youth. METHODS: A search with no date restrictions was conducted across 7 databases. Studies included any school-, home-, or community-based intervention for typically developing youth with clear intent to improve FMS proficiency and that reported statistical analysis of FMS competence at both preintervention and at least 1 other postintervention time point. Study designs included randomized controlled trials (RCTs) using experimental and quasi-experimental designs and single group pre-post trials. Risk of bias was independently assessed by 2 reviewers. RESULTS: Twenty-two articles (6 RCTs, 13 quasi-experimental trials, 3 pre-post trials) describing 19 interventions were included. All but 1 intervention were evaluated in primary/elementary schools. All studies reported significant intervention effects for ≥ 1 FMS. Meta-analyses revealed large effect sizes for overall gross motor proficiency (standardized mean difference [SMD] = 1.42, 95% confidence interval [CI] 0.68-2.16, Z = 3.77, P < .0002) and locomotor skill competency (SMD = 1.42, 95% CI 0.56-2.27, Z = 3.25, P = .001). A medium effect size for object control skill competency was observed (SMD = 0.63, 95% CI 0.28-0.98, Z = 3.53, P = .0004). Many studies scored poorly for risk of bias items. CONCLUSIONS: School- and community-based programs that include developmentally appropriate FMS learning experiences delivered by physical education specialists or highly trained classroom teachers significantly improve FMS proficiency in youth.
