What does the bioelectrical impedance analysis do?

What does the bioelectrical impedance analysis do?

Bio-electrical Impedance Analysis or Bioimpedance Analysis (BIA) is a method of assessing your body composition: the measurement of body fat in relation to lean body mass. It is an integral part of a health and nutrition assessment. Research has shown that body composition is directly related to health.

How do you calculate bioelectrical impedance?

The equation (the squared value of height divided by impedance measurements of the right half of the body) showed a correlation coefficient of 0.92 with total body water. This equation, Hoffer proved, is known as the impedance index used in BIA.

What is a healthy bioelectrical impedance?

A healthy body fat range is 15 to 25 percent of the body for women and 10 to 20 percent of the body for men. Your bioimpedance analysis results can help you and your doctor determine diet, exercise and lifestyle changes, if needed, to move toward a healthy body fat to lean muscle ratio.

How accurate is bioimpedance analysis?

We found that the MF8 BIA device (InBody 370) was relatively accurate for estimating body fat percentage (mean difference from reference of −1.1% ± 2.8%) in obese and severely obese children; however, the SF4 BIA device (Omron Portable Fat Analyzer) produced estimates of body fat percentage that were systematically 5.5 …

What is a good impedance score?

The scale is from 1-24, where 12 is the average so you want to be 12 or higher. You can improve this by improving your ratio of Muscle to Fat. Visceral Fat: This is the fat in and around your organs, the scale goes from 1-59 and the healthy range is 1-12.

What are the advantages and disadvantages of bioelectrical impedance analysis?

advantages: this method of body composition analysis is very simple and quick to perform, and if you have the right equipment can be done at home. disadvantages: The equipment is relatively expensive (units on the low end of the scale are available for about $100), with prices ranging up to thousands of dollars.

What are the advantages of bioelectrical impedance?

The advantages of BIA include its portability and ease of use, relatively low cost, minimal participant participation required, and safety (not recommended for participants with a pacemaker), thus making it attractive for large-scale studies.

What are the advantages and disadvantages of bioelectrical impedance?

What is biomedical impedance analysis?

Biological Impedance Analysis. Biological impedance analysis, or bio-electrical impedance analysis (BIA), is a method of assessing your body composition—the measurement of body fat in relation to lean body mass.

How does a scale measure BMI?

Your BMI is equal to your weight in kilograms divided by your height in meters squared. In American measurements, a conversion factor is used, so the equation reads: BMI = weight in pounds / (height in inches x height in inches) x 703. A BMI scale has this formula embedded in its programming.

What does bioelectrical mean?

Medical Definition of bioelectrical. : of or relating to electric phenomena in living organisms human cortical bioelectrical activity.
