Exercise Physiology for Type 2 Diabetes, Five Dock

Exercise physiology for type 2 diabetes sits alongside your medication, your diet and your GP's monitoring as part of how the condition is managed. An accredited exercise physiologist's job is to work out what your body can currently handle, build a program around that, and adjust it as your strength, fitness and blood glucose readings change.

This matters because working muscle draws glucose out of the blood through a pathway that does not depend on insulin. Contracting muscle moves GLUT4 transporters to the cell surface, and glucose enters. That is why a walk after dinner can shift a post-meal reading, and why building muscle mass over months gives your body more tissue capable of taking glucose up in the first place.

What a first assessment covers

The initial appointment usually runs about an hour. Expect a detailed history before any exercise happens.

Your exercise physiologist will ask about your diagnosis date, your most recent HbA1c and how it has trended, your medications and their timing, and whether you are on insulin or a sulfonylurea such as gliclazide, both of which carry hypoglycaemia risk during and after exercise. They will ask about diabetes-related complications: peripheral neuropathy, retinopathy, kidney function, cardiovascular history, foot ulcers past or present. Each of those changes what the program should look like.

Objective testing typically includes resting blood pressure and heart rate, height, weight and waist circumference, a submaximal aerobic test such as a six-minute walk or a step test, strength testing through sit-to-stand and grip strength, and a look at your feet and footwear. If you have a meter or a continuous glucose monitor, readings before and after that first bout of exercise are useful information.

By the end you should have a written program, a clear picture of which sessions go where in your week, and a plan for what to do if a reading is unusually high or low.

Weekly targets and what the program includes

Exercise and Sports Science Australia's position statement on exercise and type 2 diabetes recommends a minimum of 210 minutes per week of moderate-intensity exercise, or 125 minutes of vigorous exercise, along with resistance training and no more than two consecutive days without activity. Those numbers are a destination rather than a starting point. If you are currently doing ten minutes a week, the program starts near ten minutes a week.

A typical program combines three elements.

Aerobic work builds the bulk of the minutes. Walking around Bay Run, a stationary bike, pool walking if your feet or knees complain, or intervals if your fitness and cardiovascular history allow. Intensity is often set by talk test and rating of perceived exertion rather than heart rate, since beta blockers and other medications blunt heart rate response.

Resistance training runs two to three days a week across the major muscle groups. Legs, hips, chest, back and arms, progressed by adding load rather than just repetitions. Muscle mass is the tissue doing the glucose uptake, so this part is not optional padding.

Breaking up sitting time is the third piece. Standing or walking for two to three minutes every half hour during a long stretch at a desk or in front of the television changes the glucose pattern of that period.

Managing the practical risks

If you take insulin or a sulfonylurea, carry fast-acting carbohydrate, know your hypoglycaemia symptoms, and test before exercising until you understand how your body responds. Glucose-lowering effects can persist for hours after a session, so an evening workout can influence overnight readings.

With peripheral neuropathy, check your feet daily and after exercise, since reduced sensation means a blister or pressure area can develop without you feeling it. Footwear choice becomes a clinical decision rather than a preference. With proliferative retinopathy, heavy straining and head-down positions are usually modified, and your ophthalmologist's advice guides that.

Your exercise physiologist will also ask you to hold off if blood glucose is very high with ketones present, and will refer back to your GP for anything that needs medical review.

Referral and funding

Your GP can refer you under Medicare's chronic condition management arrangements for up to five subsidised allied health services per calendar year, shared across all allied health you use. There is normally a gap payment.

Type 2 diabetes also has a separate Medicare pathway for group services. With a GP referral you can access one individual assessment plus up to eight group exercise sessions with an accredited exercise physiologist in a calendar year, and those sessions do not count against your five individual allied health visits. For people who want more supervised contact across a year, combining the two pathways stretches the support considerably further.

NDIS participants with type 2 diabetes alongside a primary disability can often fund exercise physiology through Improved Health and Wellbeing, depending on plan goals. DVA Gold Card holders can be referred by their GP.

When to book

Common triggers include a new diagnosis, an HbA1c result your GP is not happy with, a recent medication change, or a general sense that you have been meaning to get moving for two years and need someone to structure it. Pre-diabetes is also a reasonable point to start, before the diagnosis threshold is crossed.

Bring your most recent blood results, a current medication list, your meter or CGM data if you have it, and the shoes you actually walk in.
