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. 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.
Getting On Track Assessing Body Composition Webinar Q Amp A
Effect of hydration on body fat measurement. This is especially significant after completing a vigorous workout routine. At present obesity and overweight are major public health concerns. Thus the aim of this study was to examine the effect of hydration status on. In recent years it has been suggested that water intake could have important implications for weight management. A reading below 69 may indicate dehydration and result in a fat weight reading that is 3 5 too high. Water is an essential component of living organisms and in adult mammals the fraction of fat free body mass ffm as water is remarkably stable at 073.
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. That means that your changing level of hydration can have a significant effect on the body fat reading that you get. Your body fat is pretty water dense so dense in fact that body fat is comprised of about 10 water. For an adolescent it is expected to be slightly higher. For an adult body water is expected to be 69 74 of lean body weight. Their classical determinants do not sufficiently explain the current situation and it is urgent to investigate other possible causes.
Hydration status can be useful when reviewing the results of a body composition test. The stability of ffm hydration is a corner.
