National and international experts discussed the latest uses of bioimpedance to classify hydration.

Monitoring hydration levels of the human body could help detect serious health problems early. This was one of the findings of a study presented at the panel 'hydration and body composition: health, and role models’ del 10th International Symposium on Body Composition, held in Cascasi, in Portugal, and organized by the Faculty of Human Movement (FMH) University of Lisbon.

As explained by Professor Henry C. Lukaski, researcher in the Department of Kinesiology and Health Education at the University of North Dakota, in United States, "Bioimpedance can monitor changes in the hydration of dialysis patients and anticipate future complications. You can also identify individuals with fluid retention and breathlessness. In other cases it may help to identify individuals with excess moisture associated with acute heart failure”.

The expert also noted that “other positive uses bioimpedance can lead to proper identification of alterations in hydration among the most vulnerable populations. Through this method it is possible to identify individuals who have inadequate hydration and may be at risk in terms of mental function or having complications with certain dose of medicine”.

Bioimpedance method assesses the percentage of fat, lean and hydration in the human body and to calculate ideal weight range for the individual subject by sex and age. "The future of bioimpedance ranking hydration is promising. Numerous applications in medicine and the detection of possible risk groups like the elderly and children can be targets for further investigation”, the researcher concludes.

In addition to Professor Henry C. Lukaski, The symposium featured presentations by Professor Dale Schoeller, University of Wisconsin, and Dr. Diana Thomas, Montclair University, both in the United States.The Dr. Dale Schoeller presented the results of its investigation into the adequacy of the energy balance equation. According to this expert, “determine the relationship between body weight and the amount of food we eat is fundamental to understanding the excess weight gain as we age, and losses during the treatment of obesity. This relationship is complicated, because our body is divided into two main components: fat-free mass, which is composed mainly of water, more protein components and minor, and fat mass, which is entirely fat. ".

As explained Schoeller, “water is the most important nutrient for life and constitutes almost half to two-thirds of the body weight. The measurement of body changes is not easy. Is still recent development of methods for measuring body water and its two main intra and extracellular components that allow measurements in clinical situations general”.
