Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The exercise intervention will involve 12 weeks of exercise training involving aerobic and resistance modalities. Training will be performed for approximately one hour, three times a week. Initial sessions will be supervised by an exercise physiologist/physiotherapist and then the participant will exercise independently at a community gymnasium. Aerobic exercise will commence at 50% of the baseline VO2peak and progress to 70% of the VO2peak by the end of the intervention period. Resistance exercise will commence at 50% of the one-repetition maximum and progress to 70% of the one repletion maximum by the end of the intervention period.

Summary
Brief summary
This study will investigate the effects of exercise training in adults with congenital heart disease. Thirty patients with congenital heart disease will be randomised to either a 12 week exercise training program, or control group who will mainatin their usual activities, to review the effect on vascular function, cardiorespiratory fitness, muscle strength and quality of life.
