Summary

Colorectal and thoracic surgical patients are susceptible to poor postoperative outcome including complications, mortality and increased length of stay. Preoperative physical fitness is protective against poor postoperative outcome in intra-abdominal and thoracic surgery.

The current colorectal/thoracic pathway from diagnosis to surgery is about 2 weeks and therefore interventions of longer duration are not feasible. Clinicians may be presented with a difficult choice in delaying surgery to perform prehab or cancel the pre-op intervention.

To create greater improvements in aerobic fitness, participants are required to exercise at high levels of VO2peak (e.g. ≥80% VO2peak). High intensity interval training (HIIT) requires participants to exercise at high levels of VO2peak (≥80% VO2peak) for short periods (e.g. 15 seconds) followed by a recovery (active or passive) and typically continue this pattern for 30 minutes or until exhaustion.

HIIT programmes are safe and a recent meta-analysis noted that HIIT produced a more pronounced incremental gain in participants' mean VO2peak when compared with continuous moderate intensity exercise (+1.78mL/kg/min, 95% CI: 0.45-3.11).

HITT has not been investigated as a preoperative intervention to either optimize fitness prior to surgery or reduce post-surgical complications. Preoperative HIIT is an intense intervention which will require significant participant adherence. The safety, cost and clinical application of such a programme needs to be performed. This feasibility study aims to assess the ability of HIIT to improve aerobic fitness two weeks prior to surgery and determine its feasibility.

High Intensity Interval Training Exercise programme

High intensity interval training (HIIT) requires participants to exercise at high levels of VO2peak (≥80% VO2peak). Participants exercise for short periods (e.g. 15-30 seconds) followed by periods of rest (active or passive) and typically continue this pattern for a set time period or until exhaustion.
