Study type
Interventional
Description of intervention(s) / exposure
Following baseline assessments, participants were randomly allocated to intervention or control. (The change from a three arm trial to a two arm trial was made during participant recruitment due to difficulty in recruiting adequate sample size)
The participants in the intervention group were encouraged to attend three training sessions per week over four weeks. The sessions comprised various small-sided games including soccer, basketball, volleyball, touch rugby, cricket and other non-conventional games such as ‘chain tag’, ‘rob the nest’ and ‘bullrush’. Each session lasted 45 minutes and included a 10-minute warm-up period and regular rest periods. The sessions were supervised and conducted by the three sports and exercise postgraduate students. Basic technical advice was given to the participants for safety reasons.
Participants in the control group were offered 4 weeks gym membership at the end of the trial.

Summary
Brief summary
A disproportionate number of Pacific people in New Zealand have impaired glucose tolerance and type II diabetes, potentially leading to cardiovascular disease and other complications. While a variety of lifestyle interventions are recommended to reduce these risks, to date there is insufficient research that has compared the benefits of differing types of physical activity. Individuals who engage in regular exercise demonstrate lower incidence of diabetes, improved metabolic control, reduced cardiovascular risk and fewer health problems overall. Thus exercise presents a therapeutic, non-pharmacological option for the prevention of diabetes and reduction of cardiovascular disease (CVD) amongst other health benefits. However, the benefits of differing types of physical activity in a Pacific community are largely unknown. While there is some research showing the benefits of aerobic and/or strength type exercise within the general population, there is no research that has compared these modalities of exercise to team-sport activities that are often performed in Pacific communities during organised sport and play.
Therefore, for the first time, we will compare effects of gym based activities versus small sided games to a non-exercising control group.
Encouraging results could have implications for future larger scale trials and government funded health initiatives.
