High Intensity PreHab Before Major Abdominal Surgery

The risk for major cardiac cardiovascular events (MACE) within the first 30 day after surgery is nit only associated to the patient relate risk factors but also to the kind of surgery. Surgical interventions can be distinguished infield risk (MACE \<1%), moderate risk (MACE 1-5%) and high risk (MACE \> 5%). In addition with patient related risk factors it can raise to values of 40%. The preoperative aerobic fitness \[oxygen uptake (VO2) at the ventilatory anaerobic threshold (VAT) \<11 mL/kg/min\] has been shown of particularly interest in identifying patients at increased risk of postoperative complications. In the last decade major interest was put in the question whether a preoperative personalised physical training may have beneficial effect on the preoperative fitness and on the occurrence of postoperative complications. In some small studies this benefit has been shown for abdominal and thoracic surgery. However some of those studies are controversially discussed because of missing randomisation and methodical issues. Also most of the studies needs a four week training period. This may lead to ethical and logostical problems oncologic patients. The aim of this study is to assess the effect of a personalised, high intensity trains program of two weeks on the preoperative fitness.
