Purpose: The purpose of the study is to investigate the impact of differing delivery schedules of computer-tailored physical activity modules on engagement and physical activity behaviour change in a web-based intervention targeting breast cancer survivors. Methods: Insufficiently active breast cancer survivors (n = 492) were randomly assigned to receive one of the following intervention schedules over 12 weeks: a three-module intervention delivered monthly, a three-module intervention delivered weekly or a single module intervention. Engagement with the website (number of logins, time on site, modules viewed, action plans completed) was measured using tracking software. Other outcomes (website acceptability, physical activity behaviour) were assessed using online surveys. Physical activity outcomes were analysed using regression models for both study completers and when applying intention-to-treat (using multiple imputation). Results: Completers allocated to the monthly module group rated the intervention higher (b = 2.2 95 % CI = 0.02–4.53) on acceptability and had higher levels of resistance-training (IRR = 1.88, 95 % CI = 1.16–3.04) than those in the single module group. When accounting for missing data, these differences were no longer significant. The completion of at least two action plans was higher among those allocated to the monthly module group compared to those in the weekly module group (53 vs 40 %, p = 0.02); though the completion of at least two modules was higher in the weekly module group compared to the monthly module group (60 vs 46 %; p = 0.01). There were no other significant between group differences observed. Conclusion: This study provides preliminary evidence that web-based computer-tailored interventions can be used to increase physical activity among breast cancer survivors. Further, there were some outcome differences based on how the tailored modules were delivere

© 2017, Springer-Verlag GmbH Germany. Background: Participating in regular physical activity is a recommended cancer recovery strategy for breast cancer survivors. However, tailored support services are not widely available and most survivors are insufficiently active to obtain health benefits. Delivering tailored programs via the Internet offers one promising approach. However, recent evaluations of such programs suggest that major improvements are needed to ensure programs meet the needs of users and are delivered in an engaging way. Understanding participants’ experiences with current programs can help to inform the next generation of systems. Purpose: The purposes of this study are to explore breast cancer survivor’s perspectives of and experiences using a novel computer-tailored intervention and to describe recommendations for future iterations. Methods: Qualitative data from a sub-sample of iMove More for Life study participants were analysed thematically to identify key themes. Participants long-term goals for participating in the program were explored by analysing open-ended data extracted from action plans completed during the intervention (n = 370). Participants negative and positive perceptions of the website and recommendations for improvement were explored using data extracted from open-ended survey items collected at the immediate intervention follow-up (n = 156). Results: The majority of participants reported multi-faceted goals, consisting of two or more outcomes they hoped to achieve within a year. While clear themes were identified (e.g. ‘being satisfied with body weight’), there was considerable variability in the scope of the goal (e.g. desired weight loss ranged from 2 to 30 kg). Participants’ perceptions of the website were mixed, but clear indications were provided of how intervention content and structure could be improved. Conclusions: This study provides insight into how to better accommodate breast cancer survivors in the f

Current physical activity and fitness levels among adolescents are low, increasing the risk of chronic disease. Although the efficacy of high intensity interval training (HIIT) for improving metabolic health is now well established, it is not known if this type of activity can be effective to improve adolescent health. The primary aim of this study is to assess the effectiveness and feasibility of embedding HIIT into the school day. A 3-arm pilot randomized controlled trial was conducted in one secondary school in Newcastle, Australia. Participants (n = 65; mean age = 15.8(0.6) years) were randomized into one of three conditions: aerobic exercise program (AEP) (n = 21), resistance and aerobic exercise program (RAP) (n = 22) and control (n = 22). The 8-week intervention consisted of three HIIT sessions per week (8–10 min/session), delivered during physical education (PE) lessons or at lunchtime. Assessments were conducted at baseline and post-intervention to detect changes in cardiorespiratory fitness (multi-stage shuttle-run), muscular fitness (push-up, standing long jump tests), body composition (Body Mass Index (BMI), BMI-z scores, waist circumference) and physical activity motivation (questionnaire), by researchers blinded to treatment allocation. Intervention effects for outcomes were examined using linear mixed models, and Cohen's d effect sizes were reported. Participants in the AEP and RAP groups had moderate intervention effects for waist circumference (p = 0.024), BMI-z (p = 0.037) and BMI (not significant) in comparison to the control group. A small intervention effect was also evident for cardiorespiratory fitness in the RAP group.

© Springer-Verlag Berlin Heidelberg 2014. Purpose To explore demographic, health, social-cognitive and behavioural correlates of resistance training among post treatment breast cancer survivors. Methods A sample of 330 post-treatment breast cancer survivors recruited from across Australia completed a mailed questionnaire. A multivariate logistical regression model was used to test associations between independent variables and meeting the resistance training guidelines. Results Less than a quarter of the participants were meeting the resistance training guidelines of at least two sessions of resistance training per week. Higher task self-efficacy for resistance training (p<0.01) and greater goal-setting behaviour (p<0.05) were identified as significant predictors of meeting the resistance training guidelines, with a one unit increase in task self-efficacy and goal setting, increasing the odds of meeting the resistance training guidelines by a factor of approximately 1.2 (odds ratio (OR) task self-efficacy=1.23, 95% confidence interval (CI)=1.05–1.43; goal-setting OR= 1.20, 95% CI=1.04–1.38). No other variables significantly predicted meeting the resistance training guidelines in the multivariate analysis. Conclusions Strategies targeting task self-efficacy and goal-setting behaviours are likely to be important intervention components in resistance training interventions for breast cancer survivors. Implications for cancer survivors The findings of this study will be useful for informing the development of evidence-based interventions aiming to promote resistance training among this group.

BACKGROUND: Like many other countries, Australia is facing an inactivity epidemic. The purpose of the Australian 2014 Physical Activity Report Card initiative was to assess the behaviors, settings, and sources of influences and strategies and investments associated with the physical activity levels of Australian children and youth. METHODS: A Research Working Group (RWG) drawn from experts around Australia collaborated to determine key indicators, assess available datasets, and the metrics which should be used to inform grades for each indicator and factors to consider when weighting the data. The RWG then met to evaluate the synthesized data to assign a grade to each indicator. RESULTS: Overall Physical Activity Levels were assigned a grade of D-. Other physical activity behaviors were also graded as less than average (D to D-), while Organized Sport and Physical Activity Participation was assigned a grade of B-. The nation performed better for settings and sources of influence and Government Strategies and Investments (A- to a C). Four incompletes were assigned due to a lack of representative quality data. CONCLUSIONS: Evidence suggests that physical activity levels of Australian children remain very low, despite moderately supportive social, environmental and regulatory environments. There are clear gaps in the research which need to be filled and consistent data collection methods need to be put into place.
