AB [EN] Despite  numerous  studies  related  to dehydration  there  is  still  a  lack  of  scientific  literature presenting hydration status and fluid intake of judo athletes during different periods. Therefore, the aim of this study was to investigate, fluid intake, hydration status and body weight changes of young judo athletes during  a  typical  day  of  training  in  preparation  period.  Twenty-two  young  judo  athletes  (age:  12  ±  0.7  y, experience: 3.5 ± 1.1) voluntarily participated in this study. Hydration status and weight were examined in the  morning,  before  and  immediately  after  the  training.  All  athletes  trained  90  min  and  they  consumed fluids ad libitum during the exercise. According to morning urine specific gravity (USG) values, 81.2% of the athletes   were   dehydrated   while   only   18.8%   of   the   athletes   were   euhydrated.   Pre-training   urine measurements  showed  that  63.64%  of  the  athletes  presented  dehydration  and  77.27%  of  the  athletes completed  the  training  in  dehydrated  condition  despite  fluid  availability  during  the  training.  Mean  body weight loss during training was -0.64 ± 0.66%. It can be concluded that young judo athletes presented high prevalence of dehydration as indicated by USG values. Most of the athletes were dehydrated during a typical training  day  and  completed  the  training  in  more  dehydrated  conditions  compared  to  pre  training  values despite ad libitum fluid intake. It is of great importance to evaluate hydration status of the athletes before training  to  refrain  from  common  practice  of  fluid  restriction  for  weight  loss  and  adverse  effects  of  a persistent state of fluid deficit on physical and health related state.
