Body Composition Analysis

Body Composition Tests are an effective way to assess what you’re made of on the inside (e.g. muscle mass, body fat), and to gauge if you’re on track with your fitness and health goals.

Our conversations on wellbeing often focus on the amount of weight that we want to gain or lose. What traditional measures (scales, fat calipers, BMI etc) fail to consider is that two people of the same sex and weight may look completely different from each other because they have a different body composition. Body composition is what our unique body is made up of - the amount of muscle, bone, fat and water in the body. Measuring your body composition will give you a snapshot of your unique makeup, allowing you to focus on true measues of health, rather than outdated, and often inaccurate assumptions; assisting you to make better decisions to optimise your wellbeing. 

SOZO is a bioimpedance spectroscopy (BIS) device used by therapists, sports scientists, researchers, and nutritionists for measurement and tracking of body composition and fluid. By using 256 frequencies from 3kHz to 1000kHz to measure the reactance and resistance of the body tissue to calculate fat mass, fat free mass, extracellular fluid, intracellular fluid and total body water unlike manual techniques which are subject to human error and bioimpedance analysis which use 1-11 frequencies.


SOZO is easy, painless and efficient, delivering results in less than 30 seconds. The test is non-invasive - all you need to do is stand on our machine in light clothing (there’s no poking, prodding or pinching). 

A single SOZO measurement provides critical patient data, including:

  • L-Dex lymphedema analysis

  • Total body water (TBW)

  • Extracellular fluid (ECF)

  • Intracellular fluid (ICF)

  • Fat-free mass (FFM)

  • Fat mass (FM)

  • Skeletal muscle mass (SMM)

  • Protein and minerals

  • Basal metabolic rate (BMR)

  • Hy-Dex® hydration analysis

  • Phase angle

  • Body mass index (BMI)


If you’ve had breast surgery and/or had lymph nodes removed or damaged, you may be at risk of lymphoedema. If diagnosed and treated early, lymphoedema can be controlled and reduced. Early treatment can prevent infection, improve range of movement and enhance your wellbeing.

Our Physiotherapist and Lymphoedema Therapist Kate McNabb uses the SOZO to get an L-Dex reading enabling identification of very small changes in fluid in the affected limb over time.  The SOZO uses noninvasive bioimpedance spectroscopy (BIS), which is capable of detecting fluid changes as small as 2.4 tablespoons (36ml) and takes less than 30 seconds to complete.

Tracking physical progress and monitoring overall health

SOZO, the world’s most advanced, noninvasive bioimpedance spectroscopy (BIS) device, offers a fast, simple, noninvasive way to measure the impact of physical activity on healthy patients. SOZO assesses multiple fluid compartments and body composition at the same time — without labour-intensive measuring or underwater weighing techniques — to quantify improvements in skeletal-muscle mass or decreases in fat mass.

Our Dietitian Shona Collins and Personal Trainer Holly Philpott are able to use the SOZO as a complementary assesment during your consultation. It is recommended that readings are taken at least 4 weeks apart and under similar circumstances (e.g. same time of day).
