The primary outcome for the multidisciplinary rehabilitation programme will be a change in functional capacity as measured by aerobic capacity. Secondary measures of functional capacity will include a stair climbing test, hand grip and physical activity. Body composition will also be measured by bio impedance analysis. The secondary outcomes that will be assessed are nutritional status, dietary quality and healthy related quality of life (QOL). Inflammatory profiles, measures of energy metabolism and gut hormones are unlikely to be influenced by the proposed rehabilitative intervention and therefore will not be measured. Assessments will be completed at, programme completion and three months post programme completion. Assessments take place at the Welcome Trust-HRB Clinical Research Facility St. James's Hospital. The rehabilitation programme will consist of three main components; 1. Exercise session, 2. Dietary sessions and 3. Education sessions. The intervention outlined below is devised based best evidence, pilot data and clinical expertise. The design final design will be informed form the results of the feasibility study and from needs identified in Phase I.
