Recent exercise activity. This equation hoffer proved is known as the impedance index used in bia.
Body Fat Body Composition Testing Dr Fitness Personal
Impedance body measurement. When it comes to weight body composition and your health using just scales dont tell you the whole picture. Dehydration may cause fat free mass muscle and bone to be underestimated. Depending on the electrode location the excitation frequency and the algorithm used to interpret the impedance measurement body composition such as the percentage of total body fat or the amount of body water to measure dehydration can be determined. The body fat percentage is a measure of fitness level since it is the only body measurement which directly calculates a persons relative body composition without regard to height or weight. Accuracy through multi frequency measurement. High intensity exercise may affect the accuracy of bia readings.
Actually your weight is less important than your percentage of body fat when it comes to appearance fitness and health. However the inbody accurately analyzes the total body composition by separately measuring impedance of the body trunk aka torso which accounts for as much as 50 of total body weight and has different cross sectional areas than the arms or legs. A number of methods are available for determining body fat percentage such as measurement with calipers or through the use of bioelectrical impedance analysis. Bioelectrical impedance analysis may be less accurate in obese people. The equation the squared value of height divided by impedance measurements of the right half of the body showed a correlation coefficient of 092 with total body water. Hydration level.
Guide to buying bioelectrical impedance body fat monitors. Fortunately there are body fat monitors which can help. In 1969 hoffer concluded that a whole body impedance measurement could predict total body water. Higher frequencies go beyond the cells and can measure the intracellular fluid.
