No exercise physiologists work in Tasmanian hospitals and it's the only state, along with the Northern Territory, where this is the case.

Launceston-based exercise physiologist Matthew Fulton said he was surprised by the situation in Tasmania.

"There's no job description for us in the Tasmanian health system," he said.

"Because of the increasingly older population here in Australia and what we deal with as exercise physiologists is chronic disease, there's been a big call for exercise interventions to manage the chronic disease burden."

Mr Fulton said if exercise physiologists were employed in hospitals they could help people recover quicker, remain independent and avoid further hospitalisations.

"We basically help people manage their chronic conditions... we keep them out of hospital with our interventions," he said.

"You won't be seeing as many on waiting lists, with some of our interventions we can delay the need for things like joint replacements and those type of surgeries."

The organisation representing professionals like Mr Fulton, Exercise and Sports Science Australia, is advocating for change.

Exercise and Sports Science Australia's senior policy advisor Leanne Evans says more than 200 exercise physiologists work in hospitals across Australia.

She said a survey of the organisation's members revealed no exercise physiologists were working in public hospitals in Tasmania and the Northern Territory.

"It's not just the public system...we are not aware of any exercise physiologists being employed in the private hospital system in Tasmania as well," Ms Evans said.

"Exercise physiologists in other states work in a variety of roles and they range from cardiac rehab units to respiratory clinics.

"We've got many exercise physiologists working in mental health units."

Exercise physiologists also help people with diabetes and those recovering from cancer, living with disability and residing in aged care facilities

"A lot of our exercise physiologists in private practice are picking up the burden, certainly when it comes to Medicare and the chronic disease management care plans," Ms Evans said.

"For every dollar invested there's a minimum return of between $2 and $8 per dollar of expenditure, depending on the level of condition."

Ms Evans said the lack of exercise physiologists in Tasmanian hospitals was "disappointing and frustrating".

"I understand there is some movement in Tasmania and some of our members are actively in discussions with the Tasmanian Chief Allied Health Officer and people within the hospital system to try and rectify that," she said.

A Tasmanian Health Service spokesman said allied health professionals, including physiotherapists, were employed by the service to help manage patients' medical conditions.

"In many cases, the treatment of chronic conditions is led by primary health, and GPs are able to refer patients to exercise physiologists should they believe there is a clinical need for their specialist expertise," the spokesman said.
