This study aims to determine whether a 12-week Personal Activity Intelligence (PAI) e-health Program is feasible and acceptable for improving physical activity levels, fitness and health in people from the Defence community who have undertaken cardiac rehabilitation.

Exercise is a vital component of cardiac rehabilitation, but adherence to self-directed exercise is low and this impacts long-term health outcomes.

PAI (pronounced pi) is a new fitness metric based on an individual's personal profile and the heart rate data collected during physical activity to provide a PAI score.

In this study, participants will undertake a range of health measures including vascular function, body composition, wellbeing and cardiometabolic risk. Volunteers will participate in four 2-hour sessions at the UQ St Lucia campus under the supervision of an accredited exercise physiologist. They will be given different types of exercises to reach the weekly PAI goal of 100 and can participate in the PAI e-health community. After 12 weeks we will assess the impact of the program on their health and how they found the e-health program.
