The Challenges of Evidence-based Prehabilitation in a Real-life Context for Patients Preparing for Colorectal Surgery

"Patients performed physical exercise training and/or received dietary counseling for five weeks, provided by a trained physiotherapist and dietitian (both \>15 years experience). The physical exercise training consisted of high-intensity interval training (HIIT) three times a week and functional strengthening exercises. Patients visited the hospital two times a week and performed home exercise training five times a week on a stationary cycle ergometer (Corival Home+, Lode BV, Groningen, The Netherlands).~The dietary intervention consisted of optimization of energy and protein intake, optimization of timing of eating protein-rich products, and if necessary additional protein and vitamin supplements. Individual protein requirements were set at 1.5-1.9 g/kg fat free mass. Patients used the eiFIT-application or a food diary to track their protein intake."
