ADVERSE EVENT, EVENTS
Adherence to the training intervention was measured as the number of attended training sessions out of the maximum possible, and compliance was measured as the number of training sessions meeting a minimum of 4 min above the 90% threshold for HIIT. Compliance with the nutritional intervention was measured as the percentage of the ingested protein at the preoperative testing. No predefined measure of compliance or adherence to the medical optimization was conducted. Adverse events during the training intervention were defined as any condition arising during the preoperative phase needing medical attention or treatment. Expected events such as muscle soreness were not registered. Compliance with ERAS was measured by urinary catheter removal, initiation of normal diet and postoperative day of full mobilization defined by achieving baseline mobility. Length of stay was estimated from day of surgery until day of discharge, and by days alive and out of hospital (DAOH-30)
