Background: Lifestyle modifications including, physical activity can reduce obesity‑related morbidity and subsequent cardiovascular disease in youth. This study will investigate the efficacy of a culturally‑sensitive, non‑contact, boxing‑orientated training program on obesity and related cardio‑metabolic conditions in Māori and Pasifika adolescents. Details of the methodological aspects of recruitment, inclusion criteria, randomization, cultural sensitivity, intervention program, assessments, process evaluation, and statistical analyses are described.

Methods: This study will be a community based, New Zealand, randomized control trial (RCT). Male and female obese (body mass index >95th percentile) Māori and Pasifika adolescents aged 14‑16 years will be recruited and the sample size will be confirmed through a feasibility study. Combating Obesity in Māori and Pasifika Adolescent School‑children Study (COMPASS) is a 6‑month, theory‑based program, conducted 3‑times/week in a culturally appropriate setting. Each session includes 40 min boxing‑orientated training and 30 min resistance training. Assessments will be made at baseline, 3‑months, 6‑months, 12‑months, and 24‑months. Main outcomes include abdominal obesity, endothelial function, and insulin resistance. Other outcomes include arterial stiffness, lipid profile, inflammatory biomarkers, well‑being, and aerobic fitness. Control measures include physical activity, sleep behavior, and dietary intake. Analysis will by intention to treat

Results: As a protocol paper there are no specific results to present, our purpose is to share our RCT design with the scientific community.

Conclusions: COMPASS will be used to provide direction for exercise prescription policy in at‑risk Māori and Pasifika adolescents.
