What Does an Exercise Physiologist Do?
An exercise physiologist prescribes and supervises exercise for people managing chronic health conditions, injury, disability or recovery from surgery. The job is to work out what dose of movement is appropriate for a particular body on a particular day, then adjust it as that body changes. Less glamorous than it sounds, and more technical.
If you've been referred to one and aren't sure what you're walking into, this covers the qualification, the scope, and what actually separates the role from a gym trainer.
The qualification
In Australia the recognised credential is Accredited Exercise Physiologist, or AEP, issued by Exercise and Sports Science Australia (ESSA). It requires a four-year university degree covering anatomy, physiology, biomechanics, exercise prescription and the pathophysiology of the conditions AEPs work with, plus a minimum of 500 hours of supervised practicum. Most of those hours are spent with clients who have diagnosed conditions rather than healthy gym-goers.
AEPs are recognised providers under Medicare, the NDIS, DVA, workers compensation schemes and most private health extras policies. Exercise physiology sits outside AHPRA registration, with ESSA handling accreditation and continuing professional development requirements.
What exercise physiologists work with
The common referrals fall into a few groups.
Metabolic and cardiovascular conditions. Type 2 diabetes, prediabetes, high blood pressure, high cholesterol, obesity, and cardiac rehabilitation after a heart event or procedure. Exercise prescription here is about intensity, frequency and monitoring, with attention to medication timing and blood glucose for people on insulin or sulfonylureas.
Musculoskeletal conditions. Osteoarthritis, osteoporosis, persistent low back pain, tendinopathy, and the long tail of a rehab program after a physiotherapist has handled the acute phase.
Neurological and disability-related needs. Stroke, Parkinson's disease, multiple sclerosis, cerebral palsy, acquired brain injury. Much of this comes through NDIS plans, where goals are framed around function and participation rather than diagnosis.
Ageing and deconditioning. Falls risk, sarcopenia, recovery after a hospital admission, and the general loss of capacity that follows a few months of doing less.
Mental health. Exercise is sometimes included as part of a broader management plan for depression and anxiety, coordinated with the GP or psychologist managing care.
How this differs from a personal trainer
Personal trainers are trained to work with apparently healthy people. A good one can coach technique, build training programs and keep you accountable, and plenty of people with stable conditions do fine in that setting.
An AEP's training is aimed at the complications. What happens to blood pressure during isometric work in someone on beta blockers. Why a client with peripheral neuropathy needs different footwear and different balance progressions. When post-exertional malaise means the standard progression model is the wrong tool. How to load a tendon that's been grumbling for eight months. How to build a strength program around osteoporosis without avoiding load altogether, since avoiding load is part of what causes the problem.
The other difference is documentation. AEPs report back to the referring GP or specialist, write progress notes against plan goals, and work inside funding frameworks that require evidence of what was done and why.
What a program actually looks like
An exercise physiologist starts with assessment: history, medications, relevant test results, and objective measures such as a 30-second sit-to-stand, gait speed, balance testing, grip strength and blood pressure response to effort.
From there the program specifies variables rather than vague advice. How many days a week. Which exercises. How many sets and repetitions. What load. How hard each set should feel, usually described using rate of perceived exertion or repetitions in reserve. What to do if something flares.
Progression is where the clinical reasoning shows. Adding load too fast creates flare-ups; never adding it means nothing changes. The adjustment might be a kilogram on a dumbbell, a set added, a chair removed from a balance exercise, or ten seconds taken off a rest period. For people in persistent pain, the starting point is often lower than they expect and the build is slower, because a setback in week two tends to cost more than the gains it chased.
Sessions are frequently a mix of supervised work in the clinic and a home program, with the home program doing most of the volume.
How to get started
You can see an exercise physiologist privately without a referral. For subsidised access, the main routes are a GP chronic condition management plan under Medicare, an NDIS plan with relevant capacity building funding, a DVA referral, or an approved workers compensation or CTP claim. Private health extras cover varies by fund and policy.
If you have a diagnosed condition and the advice you've been given amounts to "try to exercise more", an exercise physiologist is the person who turns that into a specific plan you can follow.
You're welcome to book an initial assessment at the Five Dock clinic, or ask about a home visit if getting to the clinic is difficult.
