Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Exercise programme, three times per week lasting for 1- 1.5 hours after school for 12 weeks. The moderate intensity exercise sessions will be run by two post-graduate Health Science and Exercise and Sports Science students. The intervention will use the principles of motivational interviewing and involve games and exercise routines designed by the post-graduate students with advice from the Sports and Exercise supervisor and in consultation with students. A healthy snack (e.g. fruit and milk/water) will be offered at each session. The post-graduate students will discuss achieving recommended levels of physical activity in every-day life and setting physical activity goals.
