Abstract Purpose/ Background Prehabilitation aims to improve physical condition in the preoperative period and, therefore, decrease the loss of cardiopulmonary capacity postoperatively, with the aim of reducing complications and promoting an early recovery. This study aims to evaluate the impact of home-based prehabilitation on the physical condition of patients treated surgically for colorectal cancer. Methods A prospective and randomized clinical study was conducted in 60 patients during two periods, October 2018 - September 2020, in a single university hospital. Patients were randomized into two study groups (30 per group): prehabilitation vs standard care. Changes in physical condition, measured at diagnosis, the day before surgery, and at 6-8 weeks after surgery using Cardiopulmonary Exercise Test (CPET) and the 6-minute walk test (6MWT) were evaluated. Results Prehabilitation reduce postoperative complications (17.4% vs 33.3%, p=0.22) and hospital stay (5.74 vs 6.67 days, p=0.30). 6MWT showed a significant improvement in prehabilitation group (+78.9 meters). Six weeks after surgery, prehabilitation showed a significant improvement in the 6MWT (+ 68.9 meters vs - 27.2 meters, p=0.01). Significant differences were also observed in the ergospirometry between the diagnosis and postoperative study (+ 0.79 METs vs - 0.84 METs, p=0.001). A strong correlation was observed between CPET and 6MWT (0.767 (p
