Water is involved in virtually all body processes. It is the most essential element for our survival. Most important of all there are no calories in water. The body has two main water compartments. Intracellular Fluid (ICF) fluids within the cell and Extracellular Fluid (ECF) water outside of the cell. ECF includes blood plasma and the interstitial fluid that occupies the spaces between the various tissue components. The blood plasma serves as the common connection between the internal (ICF) and external (ECF) cellular environments. ECF includes lymph, saliva and eye fluids and joints, fluids secreted by glands and the intestine fluids that bathe the nerves of the spinal cord and excreted from the skin and kidney.

Almost 75% of a child’s Body Mass is water. In adults not only is there difference in Total Body Water due to variation in body composition (Lean vs. Fat Mass), but gender based. The water range of male is typically about 57-65% and female about 46-53% of Total Body Mass. The difference between the two genders is primarily attributable to the difference in body fat. Almost 65 to 75% of muscle weight constitutes water, whilst Body Fat has the least approximately 20 to 30%. Bone contains about the same amount of water as Body Fat.
Body Composition of individuals who are leaner and muscular has a larger content of water than their counterparts who are fatter, with the same body mass. With age the contents of the body’s water changes due to age related variations in body composition.
Generally the water content of the body normally remains relatively stable over time. In most cases the water output far exceeds water intake. However, the imbalance is quickly adjusted by the body with appropriate ingestion of fluids.
For sports and professional athletes, not only is low body fat desirable to optimize physical performance, but to have correct hydration status is important. Regular use of Maltron Body Composition Analyser will help provide information to estimate the optimal body weight.
For most of us a daily intake of water is less than half of our daily requirement. An adult with a sedentary lifestyle requires about 2.5 litres of water each day. Considerable variation may exist in total water due to the difference in the body composition and our food intake. The extent of the variation can be effected by the general environmental condition and participation in physical activity.
Liquids, foods and metabolism are the main three sources from where water can be obtained. In certain professional sectors water intake is deliberately restricted to lower or maintain body weight. Such practices are more common in some fields than in others. Some individuals on weight loss programs believe restricting fluid intake results in loss of body fat more rapidly.
The regular uses of Maltron Body Composition Analyser will help register changes in Body Mass before and after exercising. Athletes are normally weighed before and after practice. The weight loss is minimized by periodic water breaks during activity. The thirst mechanism is an imprecise guide to water needs. If dehydration was entirely our responsibility it would take us several days to re-establish fluid balance, especially after severe dehydration.
