DISCUSSION 



Hingerty : Are these differences in the intracellular water related to the 

 proportion of functional muscular tissue? Have you any comparative 

 data for women athletes, for example? 



Olesen : We have no measurements on muscle mass, but we assume that 

 there may be differences due to variations in muscle mass. 



Black: Have you analysed your subjects in terms of their occupation? 



Olesen: We have not investigated that, but it could probably be done. 

 I have the impression that muscular females have higher exchangeable 

 potassium relative to body weight than the fat ones. 



Kfecek : Babies of six months have the highest total body water. Have 

 you seen any relationship to the weaning of these babies at this period? 



Olesen : I have no data on this question. 



Widdowson : Dr. Olesen, can you tell us approximately at what age the 

 fat-free body tissue of the baby becomes adult, or chemically mature, as 

 regards its intracellular-extracellular relationships?
