Design outcomes

Primary

MeasureTime frame
Feasibility primary outcomes: 1. Recruitment (how many Y7 pupils opt-out/how many are available to participate, how many Y12/13 pupils consent to participate) measured using opt-out forms returned compared with forms given out at baseline 2. Retention (how many pupils are still involved at the end of the intervention, how many attend each session) measured using registers at baseline and week 8 3. Acceptability (do Y7 pupils and Young Leaders enjoy the sessions, did teachers find the timing/format acceptable, did they notice any changes in the pupils) measured using focus group discussions at week 9

Secondary

MeasureTime frame
1. Change in physical fitness measured using the 20 m shuttle run test, handgrip strength, standing long jump, and sit-and-reach test at baseline and week 9 2. Change in physical activity measured using data collected by the Actigraph accelerometer at baseline and week 9 3. Change in body composition measured using a BMIz-score from height and weight at baseline and week 9 4. Changes in the Y7 questionnaire assessed at baseline and week 9: 4.1. Health-related quality of life measured using KIDSCREEN-27 4.2. Participation in sports clubs measured using the Youth Sports Survey 4.3. Self-efficacy measures using the self-efficacy for physical activity scale 4.4. Enjoyment measured using the physical activity enjoyment scale 5. Changes in Young Leaders measured using a questionnaire on health-related quality of life, sports participation, and an adapted version of the Coaching Efficacy Scale at baseline and week 9 6. Exercise intensity measured in approximately half the Y7 pupils using a wrist-worn heart rate monitor to check that the intensity of the exercise is high enough during the HIIT sessions 7. Perceived exertion measured using the children’s OMNI scale during the HIIT sessions, again to check intensity
