A Review of Bioelectrical Impedance Analysis As a Means To Calculate Body Composition

Gauges and weighs always enough for those who want more data on the rate at which you burn fat and build muscle. People use various techniques to obtain information on the composition of your body and bioelectrical impedance analysis or BIA is one of the most common methods in this regard. To understand the advantages and disadvantages of this technology, we must first discuss what it is.

BIA is based on the fact that muscle tissue allows your body to retain water, whereas adipose tissue contains little water. A person with more muscle instead of fat, also has more water because water is an excellent conductor of electric current, the tissues of a muscular person will have less electrical resistance of an obese person. BIA devices using send a very small electric current through the human body and to estimate the percent body fat based on electrical resistance.

In most devices that depend on the BIA, the conductivity of tissue is not the only variable in the calculation of body fat percentage. The generally weak electric current passes through the legs and the proportion of fat stored in the body is lower in women than in men. For this reason, you often have to manually enter information about your gender, age and scales to help make more accurate estimates of the composition of tissues height.

The main advantage of the BIA is their scales of applications available for the home. While professional athletes often have the finances and motivation to pay for expensive services monitoring body composition in special schools, lay want a solution that takes less time and money. Body fat scales with BIA technology to meet this demand. They are available at a scale comparable to that of a simple bath and allow to obtain useful information about how diet affects your body without having to visit the doctor's office or gym price.

Although there is a growing interest in the balance of body composition, a considerable number of consumers questioned the reliability and accuracy of these devices. Honestly, there is some merit to your questions. BIA technology depends heavily on the ability of water in the body to conduct electricity and the variation in hydration level can lead to large fluctuations in the calculation of body composition. That is why people often is a radical difference between the calculated body composition before and after exercise. Cardio or weight training alter the level of fluid in the body quickly enough. The same happens when you eat or drink. Long story short, you must consider how you're hydrated before entering a body fat scale to obtain an accurate reading.

In conclusion, an impartial review of bioelectrical impedance technology reveals which has advantages and disadvantages. What we can say with certainty is that it is the best choice for domestic applications.
