Brief summary: An aneurysm is a permanent and localized dilatation of an artery usually more than 50% of its normal diameter. Abdominal Aortic Aneurysms (AAA) is an aneurysm of the main artery of abdomen and affects 5% of men aged 65-74 years. Rupture of an aneurysm is the 10th leading cause of death in white men over 65 years of age in industrial countries. Treatment of asymptomatic AAA is considered when the diameter of an AAA reaches 5.5 cm. There are two treatment options available: conventional open surgical repair or endovascular repair, which is a less invasive mode of treatment. After the operation heart and lung complications are significant in patients undergoing major abdominal surgery. The commonest causes of death are due to heart problems. There are various studies which have shown benefits of pre operative exercise training in patients undergoing orthopaedic, lung and heart bypass surgery. Currently, there is no data available with regards to the effect of pre-operative (before operation) supervised exercise in patients undergoing surgery for an AAA.

The main aim of this study will be to determine whether a pre-operative supervised exercise programme improves post-operative (after operation) outcome, compared to standard treatment.

Patients will be entered in the study once a decision to repair their AAA has been made by the consultant. They will undergo pre-operative assessment and will be divided randomly into two groups. One group will have exercise training for 4-6 weeks before surgery and the other will not. After the operation they will be followed during the post-operative period to determine the presence or absence of complications. It is anticipated that complications will be less in the group which has undertaken exercise training before operation.
