Plain English summary of protocol
Background and study aims
Many children do not do enough physical activity. Girls are less active than boys. Getting low-active girls to do more physical activity would improve their hearts, lungs, and mental well-being. There is a lack of studies that focus on ways to help girls to be physically active. Dance is an activity that appeals to many girls and could engage low-active girls in physical activity. The Bristol Girls Dance Project (BGDP) is a study that aims to examine; a) whether participating in an after-school dance programme positively affects the physical activity levels of Year 7 girls, and b) the cost-effectiveness of this approach.
Who can participate?
The study will take place in 18 state maintained secondary schools in the greater Bristol area. We aim to recruit up to 33 Year 7 girls from each school to take part in the study.
What does the study involve?
To determine how well the programme works on children, there will be nine schools that receive the after-school dance programme (intervention schools), and nine schools that do not (control schools). The schools will be randomly allocated to the 'intervention' or 'control' group of the study. The dance programme will be led by expert dance instructors, and there will be 2x75 minute sessions per week in each of the nine schools (40 sessions overall). We will examine whether the intervention results in higher levels of physical activity at the end of a 20-week dance programme. We will also assess if this effect is maintained once the programme has ended. We will monitor all financial expenditure against a formal checklist.
What are the possible benefits and risks of participating?
The main potential risk is that a girl may develop a minor sport injury
Where is the study run from?
18 state maintained secondary schools in the greater Bristol area

| Study acronym | Active7 |
| Study objectives | The main hypothesis is that participating in an after-school dance intervention will increase the physical activity levels of Year 7 girls, and that these effects will be maintained a year after the baseline measures have been taken - when the intervention has been removed. |
