Description of intervention(s) / exposure
The Wollongong Sport Physical Activity Program - is a multi-component intervention comprising a homework club and a group physical activity program. The program will run two afternoons a week (Monday and Wednesday for girls, Tuesday and Thursday for boys) between 3pm and 5pm for 30 weeks. It will be delivered on site at our local partner school; a public primary school in the Wollongong region. Participants will take part in a homework club for the first 30 minutes of each afternoon session, where they will complete their prescribed homework under the guidance of the facilitators. Children, who do not have homework, will be provided with worksheets that have been specifically developed for the target age group. A healthy afternoon snack will also be provided at this time. Participants will then participate in 90 min of moderate-intensity physical activity, based on age-appropriate, small-group, sport drills, games and recreational physical activities (themes include, for example, netball/basketball, dance, soccer, touch football). The program activities are designed with an educational focus, with the goal to be fun, engaging and inclusive. For the girls, a dance concert will be performed for parents, siblings and friends at the end of the program, while the boys will participate in a finale soccer match for family and other spectators.

Comparator / control treatment
Active Control will receive the Wollongong Sport
Healthy Lifestyle Program. This is a state-of-the-art information-based nutrition and health education intervention, delivered once a week from 3:00pm-5:00pm for 30 weeks. This program aims to promote healthy eating and physical activity and reduce time spent in small screen recreation. It will include best-practice information developed by our research centre and previously used in our community-based programs, along with information taken from national documents such as the Australian Guide to Healthy Eating, Dietary Guidelines for Children and Adolescents and Australia’s Physical Activity Recommendations for 5-12 year olds. Each session will also include 20-30 minutes of group physical activities.
Participants will also take part in a homework club for the first 30 minutes of each afternoon session. A healthy afternoon snack will also be provided at this time.

Weekly newsletters will send home for participants and their parents. The newsletters are a maximum of 2 x A4 pages and will focus on physical activity recommendations, small screen recreation guidelines and dietary information aimed at guiding healthy eating choices.

Primary outcome [2] 238302 0
Adiposity: (1) Height and weight (used to calculate Body Mass Index [BMI] [kg/m2] and BMI z-score) - Portable stadiometer, and portable electronic scales (BC-418MA Body Composition Analyser); BMI z-score will be calculated using lmsGrowth (Medical Research Council, United Kingdom), to adjust BMI for age- and sex-related changes in height and weight. (2) Wasit Circumference - non-extensible steel tape measure (measured at the level of the mid point between the lower costal border and the iliac crest). (3) Fasting blood tests will be taken by paediatric phlebotomists from a National Association of Testing Authorities (NATA) accredited pathology service to examine change in participants' fasting total cholesterol, High-density lipoprotein (HDL) cholesterol, Low-density lipoprotein (LDL) cholesterol, triglycerides, glucose and insulin. (4) Physical activity - Objective assessments of physical activity and sedentary behaviour will be measured over 8 consecutive days using the GT1M Actigraph accelerometer. (5) The Children's Leisure Activities Study Survey (CLASS) sedentary behaviour questionnaire will also be used in the study to assess time spent in specific small screen recreation activities. Parents will proxy-report their child's time spent watching television, DVDs and videos, and playing on the computer by filling in the CLASS questionnaire, which takes approximately 10 minutes. The CLASS questionnaire is culturally specific to Australian activities and has established validity in primary school children (Telford, Salmon, Jolley & Crawford, 2004). (6) Cardiorespiratory fitness - 20M shuttle run test (Leger & Lambert, 1982).

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Recruitment will commence in November 2009, prior to the program start date in March 2010.
Numerous recruitment strategies will be employed to enhance recruitment success.

Thirty girls and thirty boys, aged 8- to 11-years, will be recruited from our partner school and 10 local primary schools which have a high proportion of students from low-income neighbourhoods. (1) Advertisements will be placed in school newsletters and (2) an information session will be held at our partner school. (3) A Wollongong Sport hotline will be set-up for all enquiries (potential participants will be screened to see if they meet the eligibility criteria) and then information sheets and consent forms will be sent to the parents. (4) School teachers will also be asked to identify children with low perceived physical competence, enjoyment of physical activity or who are generally not active. (5) A ‘trial session’ will be offered to potential participants prior to the commencement of the program, which will allow children and parents to meet the program facilitators and trial the activities. This strategy was successful in the previous feasibility trials and will be supported by a presentation to parents, outlining the philosophy and goals of the program and the study.

Once written consent is received, participants will be randomized into either the intervention group (The Wollongong Sport Physical activity Program) or the control group (The Wollongong Sport Healthy Lifestyles Program). Allocation was concealed: central randomization by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be completed following baseline measurements to minimise withdrawal. Participants will be stratified by gender and randomised, using a computer-based random number-producing algorithm and the biased-coin method, to either the Wollongong Sport Program (WSP) intervention group or the active placebo group by the consultant statistician. To prevent allocation bias, the researcher recruiting participants will be kept blind to the allocation sequence.
