Bio-Electrical Impedance Analysis Q & A

What is bioelectrical impedance analysis (BIA)?

Bioelectrical impedance analysis (BIA) is a safe and innovative tool that measures body composition. More specifically, it measures your body fat and lean muscle mass. 

Your primary health care provider may use your body mass index (BMI) to assess health. BMI is a mathematical equation that estimates body fat using your height and weight. Though BMI is an effective tool for assessing body composition, it may not accurately reflect your fat and muscle mass. 

Bodybuilders, for example, may have an elevated BMI but very little body fat. Conversely, a person with a normal BMI may have more body fat than lean muscle mass. 

Knowing your true fat to lean body mass ratio paints a more accurate picture of your health and wellness. 

How does bioelectrical impedance analysis (BIA) work?

BIA uses a low-level electrical current to measure your body composition. Your certified personal trainer places an electrode on your right hand and your right foot. 

The electrode sends an electrical current through your body, which you can’t feel. The flow of the current changes as it hits different types of tissue. It flows quickly through tissue that contains high amounts of fluid but slows down when it hits fat and bone. 

The BIA then uses a mathematical equation to measure your body fat and lean muscle mass percentage. 

How do I prepare for my bioelectrical impedance analysis (BIA)?

Your certified personal trainer at MPOWER Performance Institute provides specific instructions on how to prepare for your BIA so you get the most accurate results. 

The team recommends you:

  • Avoid alcohol for at least 24 hours before your analysis
  • Eat your last meal four or more hours before your appointment
  • Drink 16-24 ounces of water two hours before your BIA
  • Avoid caffeine at least four hours before your test
  • Exercise four or more hours before your analysis

The team also requests you not put any lotion on your hands or feet on the day of your BIA. 

What happens during bioelectrical impedance analysis (BIA)?

A BIA is a safe and painless test. During your analysis, your certified personal trainer has you lie on an exam table. They place the electrodes on your hand and foot and start the analysis, which only takes 30 seconds.

After your BIA, your personal trainer reviews the results with you. Together, you develop a plan to improve or maintain healthy body composition.

Your personal trainer repeats the BIA to track changes and keep you motivated.
