چکیده

Background: this study was developed to establish whether betaine was present in the sweat of females and to determine any correlations with other sweat components.methods: sweat patches were placed on eight trained adolescent highland dancers (age = 13.6 ± 2.3 yr),who then participated in a dance class for 2 hours. patches were removed,and the sweat recovered via centrifugation. the sweat was subsequently analyzed for betaine,choline,sodium,potassium,chloride,lactate,glucose,urea and ammonia.results: betaine was present in the sweat of all subjects (232 ± 84 μmol·l-1),which is higher than typically found in plasma. the concentration of several sweat components were correlated,in particular betaine with most other measured components.conclusion: betaine,an osmoprotectant and methyl donor,is a component of sweat that may be lost from the body in significant amounts. © 2010 craig et al; licensee biomed central ltd.
