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.

Summary
Brief summary
The aim of this pilot study is to test the feasibility of a group-based exercise program over 6 weeks, test research processes and explore effects on cardio-respiratory fitness (VO2max), insulin resistance, glycosylated haemoglobin (HbAlc), blood pressure, waist circumference, and physical activity levels in less-active Pacific and Maori adolescents at a local decile 1 secondary school.
Methods:
Study design: Before-after study
Setting: Community gym
Study population: Adolescents attending low decile college who are doing less than two organised exercise or sports sessions per week on a regular basis.
Intervention: 6 week exercise program, three times per week lasting for 1- 1.5 hours. The exercise sessions were run by post-graduate Health Science and Exercise and Sports Science students. The intervention used the principles of motivational interviewing and involved 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) was offered at each session. The post-graduate students discussed achieving recommended levels of physical activity in every-day life and setting physical activity goals.
Outcome measures were collected after informed consent and immediately before the start of the 6-week exercise program.
Primary outcome measures: (assessed at baseline and 6 weeks)
1. Cardio-respiratory fitness (VO2max): as assessed by the ‘1-mile walk test’.
2. Insulin resistance: calculated according to Homeostatic Model, using fasting blood glucose and insulin levels 2
Secondary outcomes: (assessed at baseline and 6 weeks)
1. Usual physical activity levels: using the short form of the international physical activity questionnaire (IPAQ)3, (and accelerometer and smart phone on a sub-sample)
2. Waist circumference
3. HbA1c
4. Blood pressure
5. Fasting lipid profile
Attendance at exercise sessions and any injuries was also recorded.
