The AlterG treadmill is a piece of physical therapy equipment that is a highly effective athletic conditioning tool for both recreational and competitive athletes by allowing the user to train longer, run faster, gain additional strength, and enhance cardiovascular performance while minimising impact and stress on their joints.

Available to all! Bookings with front desk. For your first appointment, you will be given a detailed run down of how to use the machine.

High Performance

The AlterG has many benefits for our local running and triathlon community. Running in an off-loaded environment reduces the load on the lower extremities which has several benefits:

  • Increased mileage without the injury risk
  • Return to activity sooner after an injury
  • Increase top speed
  • Maintain speed/intensity, even when injured, without worsening the condition

The AlterG at The Sports Clinic is the medical rehabilitation model with technology developed at NASA and further developed by AlterG for fitness and sports performance training.


Working in conjunction with your physiotherapist, the Alter G will literally help you get back on your feet sooner.
The Alter G reduces your body weight by up to 80%, therefore reducing the load on your lower extremity. Patients find they can return to activity sooner without the pain experienced with full body loading.
The benefits of this are twofold: loading the affected area safely (e.g. in hip replacements where patients are asked to walk as soon as practical) whilst maintaining normal gait patterns (which is the first goal of rehab).

Typical scenarios include:

  • Post orthopaedic surgery
  • Neurological conditions including loss of balance and stroke
  • Post injury
  • Restoration of normal gait

The Alter G uses a sealed system so is a safe environment for clients who aren’t as mobile, or need assistance with their balance. A great confidence booster!

Weight Loss

The enclosed nature of the AlterG provides for a safe environment for all. The AlterG may be a suitable alternative to increasing aerobic conditioning, without the negative consequences of high impacts and loading during normal running.

NB: there is a maximum weight allowance of 180 kg.
