Following post-surgery testing, patients in the exercise group will resume the exercise programme. The duration of the sprints will restart at 10 seconds in the first week, 15 seconds in the second week, and 20 seconds in the remaining weeks. The exercise routine will be continued until follow-up treatment or for a period of up to 6 weeks. Before or after one of the 3 weekly exercise sessions, patients will receive a 30/40-minute face-to-face session with a psychologist. The aim of these sessions will be to reduce emotional distress, improve mental adjustment, promote a sense of personal control over current experience, develop effective coping strategies for dealing with cancer-related difficulties, and open expression of emotion. If patients cannot attend psychological support sessions then they will be offered the opportunity to catch up through a session over the phone.
