A 2013/14 New Zealand Health survey showed that 51% of adult New Zealanders met the New Zealand physical activity guidelines. Pacific adults were 10% less likely to be physically active, and were 2.5 times as likely to be obese as non-Pacific adults. Improving aerobic fitness levels and creating habitual physical activity behaviours, reduces the risk of cardiovascular diseases, colon and breast cancer, diabetes and depression. A physical activity intervention over four weeks or more is an important tool in the prevention and treatment of obesity. This feasibility study will look at a six-week exercise intervention within Pacific sedentary individuals participating in a group fitness exercise environment. The aim is to analyse the effects of the group exercise intervention on the individuals new to an exercise routine, comparing morphological, physiological and psychological variables at baseline, mid and post testing.
