Mr Schmidt said before the surgery he had not been able to walk very far or play bowls for a year.
"But now I can start playing bowls again for the season. The secret to a quick recovery is exercise and I would encourage anyone preparing for an operation or recovering from one to exercise and walk in the pools," he said.
Candace Sixtus from the Whanganui District Health said other people who would benefit from Green Prescription include those at risk of arthritis, those with type 2 diabetes or pre-diabetes, and those with weight issues, high blood pressure or high cholesterol.
A Green Prescription may include group fitness classes, strength and balance classes, water-based exercise, or walking groups.
Mrs Sixtus said 95 per cent of Green Prescriptions are issued by a GP or practice nurse, with the remainder coming from midwives or hospital specialists. The Whanganui District Health Board contracts Sport Whanganui to deliver the Green Prescription programme.
"If Green Prescriptions can help people increase the level of exercise they do to improve their health and quality of life, it's a win-win for them and our health system," Mrs Sixtus said.
