Top Techniques To Measure Body Fat
The four major methods of measuring body fat include the Navy Method, Home Body Fat Scales, Skinfold Calipers and Hydrostatic Weighing. For this article however; we will concentrate on the three most commonly used.
Lets discuss Home Body Fat Scales. Bio metrical Impedance is used to measure body fat using a small electrical charge. The charge is passed through the body and the resistance is measured. Your body fat can be determined when the result of the measurement is compared to your weight.
There are many factors that can affect the outcome of this test. This is the most error prone of the tests in this article. The electrical currents from the heart and the skeletal muscles can affect the results; as can water in the body. Skin temperature and physical activity can also have a direct impact on the test readings. Exercise should be avoided for at least 12 hours before the test as well as food for 4 hours before.
The most commonly used method for determining body fat is the Skin Fold Caliper test. It is possible to do this yourself if you have an easy to use caliper and follow the direction closely. The Accumeasuer Caliper is probably the best choice if you do it yourself. It is highly recommended that you have this test done by a professional to get accurate results. A set of body fat calipers is used to take several measurements on different body parts. When these measurements are plugged into a formula your body fat can be determined.
Hydrostatic Weighing- Hydrostatic weighing; also known as under water weighing is the most accurate way to calculate body fat. That is if you can find a hydrostatic weighing tank. How is it used? First you need to understand the Archimedes Principle. If you took physics in school, you will understand this better. But if you did not, I will explain it now. You or the examiner calculates your body density by measuring the amount of water you displace when you immerse yourself in water. The Archimedes principle reasons that the amount of water displaced when an object is partially or totally immersed in water, is proportional to the weight of that object. In this case you are the object. Then a formula is used to calculate body fat based on your body density. The problem is finding a hydrostatic weighing tank! This is too sophisticated for most people; but it remains the most accurate.
Does it really matter if you keep track of your body fat? Most people would say its way too much trouble. With all the different exercise programs and diets out there; knowing what your body fat is can help determine what program you should choose. It should be a vital part of your weight loss plan. Fat loss is just as important as limiting calories and losing pounds. If you want to track your diet or exercise plan progress, then body fat measurement is the most objective way to do this. When trying to lose weight, always remember to set realistic goals and don\’t give up!
