A new study has confirmed exercising before an operation will substantially improve your recovery.

Researchers at Otago University collated data from their own and other existing studies and found high intensity interval training can reduce the risk of surgery complications by 56 percent.

Lead researcher Dr Kari Clifford says even a brief four week programme makes a difference, while also giving patients agency at a time when they may not feel in control.

Clifford says it's something meaningful they can do before their surgery that will actually improve their outcome.

She adds getting people out of recovery sooner will alleviate pressure on the sector.
