Digital Home-Based Prehabilitation Before Surgery

"* Nutritional optimization: A nutritionist will perform a structured interview, comprehensive nutrition assessment, and provide personalized dietary advice. The main goal is to ensure optimal protein intake to support exercise-induced anabolism. A daily protein intake of 1.2-2.0 g/kg will meet needs as outlined in surgical nutrition guidelines.~* Exercise: Based on current guidelines and instructed by a dedicated physiotherapist, for 1 hour per day preoperatively to increase muscle strength, aerobic capacity and physical endurance. Intensity will be based on the rate of perceived exertion using the Borg scale, a 15-graded scale ranging from very light to very hard. Resistance exercises will target upper/lower body, and abdominal muscles.~* Psychological coaching and support: Performed as one interview during inclusion, followed by weekly phone calls by a study nurse coordinator during the preoperative intervention."
