The effects of an exercise program on total daily energy expenditure

For insufficiently active adults aged between 18 and 60 years, does participating in the 40-day physical activity program extensive exercise group compared to the 40-day physical activity program moderate exercise group or no intervention have an effect on energy expenditure, physical activity patterns or resting metabolic rate?

Brief summary

The University of South Australia is conducting a research project looking at the effects of a physical activity program on adults aged between 18 and 60 years who exercise for less than two and a half hours each week. This study is interested in finding out how people change their daily activity patterns and energy expenditure when they are involved in a structured exercise program.’

Interventions

Group A: 40-day physical activity program extensive exercise group (method: 3x60min monitored group sessions and 4x30min self directed sessions per week, duration: 40 days, mode of administration: half monitored group sessions, half self-directed). Group B: 40-day physical activity program moderate exercise group (method: 3x60min monitored group sessions per fortnight, 2x30min self directed sessions per week, duration: 40 days, mode of administration: half monitored group sessions, half self-di

Group A: 40-day physical activity program extensive exercise group (method: 3x60min monitored group sessions and 4x30min self directed sessions per week, duration: 40 days, mode of administration: half monitored group sessions, half self-directed). Group B: 40-day physical activity program moderate exercise group (method: 3x60min monitored group sessions per fortnight, 2x30min self directed sessions per week, duration: 40 days, mode of administration: half monitored group sessions, half self-directed) The type of exercises completed in group A and B will involve a range of activities, which may include walking, aerobic circuits, core stability and flexibility sessions, sports, beach activities, swimming, dancing and kite-surfing. The difference between group A and B is how often these activities are completed.
