Resumo
[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 o
f 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 a
nd 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 eu
hydrated. 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 traini
ng 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 conditi
ons 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
persis
tent state of fluid deficit on physical and health related state.
