Body measurements Info

Hydration affects the reading of these scales because the electrical signal will pass slower or faster through a fat free tissue depending on the concentration of electrolytes in that tissue concentration of electrolytes goes up in dehydrated tissue. By increasing the amount of water in your body youre effectively increasing your lean tissue amount and decreasing your body fat percentage. On the flip side it soars through fat free mass such as muscle which contains 70 to 75 percent water. This is especially significant after completing a vigorous workout routine. Body fat measurements of the subjects in the bod pod control group ranged from 173 to 46 table 7 and the average was 301 table 5. As you probably know the dxa scan categorizes all non bone and non fat matter as lean tissue including blood and other fluids.

Significantly different from normal hydration state measurement using biap 0001. Bioelectrical impedance is a method of tracking body fat that occurs by sending a low voltage electrical current through the body. As can be expected the majority of the waters effect is on lean tissue. It should be noted that one subjects body fat percentage increased by a small amount. Significantly different between bia and hw p 0017. Your body fat is pretty water dense so dense in fact that body fat is comprised of about 10 water.

No significant changes observed between hydration states for hw. Twelve active adult 18 29 years males exercised at 70 vo2max on a cycle ergometer in a thermal environment 30 c to induce a 25 reduction in body mass. The effects of superhydration on percent body fat comparing hydrostatic weighing hw and bioelectrical impedance bia. That means that your changing level of hydration can have a significant effect on the body fat reading that you get. The purpose of this study was to determine the effect of exercise and thermal dehydration and subsequent glycogen supercompensation on dxa based measurement of body composition. Average body fat percentage was 2855 on the normal setting and 2648 on the athletic setting table 4.

Now that youre aware of the importance of being well hydrated to gain lean body mass youre probably curious if your hydration status can also impact fat loss efforts. Your muscle is composed largely of water. Since water is a conductor of electricity the resistance the electrical signal experiences while traveling through the body will help determine what percentage of your body is fat. Flood your body and the device will give you a falsely low fat reading. In a study by published in annals of family medicine the researchers found out that people who are obese and have a higher body mass index or bmi although bmi has its own limitations are more likely to be inadequately.
