How can you use the results of bioelectrical impedance analysis?
The present review shows that BIA is a valid and precise method for predicting body composition under controlled conditions in healthy subjects. BIA can be used to estimate fat and lean mass, both of which associate linearly with morbidity and mortality in contrast to BMI where a U-formed association is found.
What is a good BIA 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.
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.
Is bioelectrical impedance expensive?
BIA is a safe, noninvasive, and rapid means of assessing body composition; however, its validity is influenced by sex, age, and disease state. The associated equipment is fairly portable and easy to operate, although relatively expensive.
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.
How accurate is a BIA test?
How accurate are the results? BIA has a 3-4% chance of error under optimal testing conditions. Thus if your result indicates 30% body fat, this could mean you have 26-34% body fat. You can expect this same level of accuracy with other practical body composition testing procedures.
Which are considered cons for using the bioelectrical impedance scale?
Conclusions: BIA can provide running-relevant information about muscle and fat content….
- Pros: Ultrasound methodologies do not need to pinch folds.
- Cons: The biggest obstacle is finding a club, physician or physical therapist that uses this device.
What do you need to know about bioelectrical impedance analysis?
Bioelectrical impedance analysis (BIA) BIA is a method for estimating body composition. The principle of BIA is to determine the electric impedance of an electric current passing through the body . The electrical impedance (Z) consists of two components, resistance (R) and reactance (Xc).
How is body fat related to bioelectrical impedance?
Many equations are available to estimate TBW and FFM as a function of impedance, weight, height, gender, and age. In actual use, however, BIA calculations of an individual’s body fat may vary by as much as 10 percent of body weight because of differences in machines and method ologies used.
When did bioelectrical impedance analysis begin in frog?
The values for the range of standard body composition are presented in [ ]. Bioelectrical Impedance Analysis has a long history and dates back all the way to 1786, when the Italian physicist Galvani experimented with tissue structures in a frog and observed the influence electrical current had on it.
What is bioelectrical impedance vector analysis ( Biva )?
Bioimpedance vector analysis (bioelectrical impedance vector analysis, or BIVA) is a human health assessment technique based on the absolute measurement of bioimpedance.
