High-Intensity Interval Training Before Surgery May Improve Recovery Outcomes

Undertaking a short program of high intensity interval training (HIIT) before surgery may reduce postoperative complications, according to a study by the University of Otago. The study was published in the journal Surgery.

Cardiorespiratory fitness (CRF) is a measure of how well the body takes in oxygen and delivers it to the muscles and organs during prolonged periods of exercise. CRF is associated with better physical and cognitive function and a lower risk of cardiovascular disease, diabetes and cancer and fewer postsurgical complications. Growing evidence suggests that CRF can be increased preoperatively, improving postoperative outcomes. Postoperative complications occur in approximately 30% of patients, or up to 50% for frail patients.
