Short-term pre-operative high-intensity interval training does not improve fitness of colorectal cancer patients.

ABSTRACT:

Background

Pre-operative cardiorespiratory fitness (CRF) in colorectal cancer (CRC) patients has been shown to affect post-operative outcomes. The aim of this study was to test the feasibility of high-intensity interval training (HIIT) for improving fitness in pre-operative CRC patients within the 31-day cancer waiting-time targets imposed in the UK.

Methods

Eighteen CRC patients (13 males, mean age: 67 years (range: 52-77 years) participated in supervised HIIT on cycle ergometers 3 or 4 times each week prior to surgery. Exercise intensity during 5 × 1-minute HIIT intervals (interspersed with 90-second recovery) was 100%-120% maximum wattage achieved at a baseline cardiopulmonary exercise test (CPET). CPET before and after HIIT was used to assess CRF.
