Due to the lack of any comparative study related to effect of different hydration processes, this study aimed to compare the effectiveness of coach encouragement and hydration education in maintaining hydration status in child judo athletes
Forty-seven athletes participated in a four-day training camp, during which hydration status was assessed before and after training sessions under three different conditions: no intervention (control), coach-guided fluid intake encouragement, and pre-training brief one-time hydration education. Athletes were unaware of the intervention conditions assigned to each day, and the educational session was delivered without emphasizing its experimental nature. To minimize potential carryover effects, the sequence of interventions was fixed. Hydration status was objectively monitored using urine specific gravity (USG) and urine color (UC) measurements.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
This arm did not receive any intervention. They completed the training session without any encouragement related to fluid intake.
During this intervention, athletes were encouraged by their coaches to consume fluids during the training.
Behavioral: Hydration-Coach Encouragement
During this interventio, athletes were given a brief hydration education before the training session.
Behavioral: Short Hydration Informative Session
Athletes were encouraged by their coaches to consume fluids during the training session.
Also known as: Encouragement
Athletes were given a brief educational session related to importance of hydration before the exercise session.
Also known as: A brief hydration education
hydration status (i.e., urine specific gravity and urine colour)
A urine sample was taken from each athlete one hour before and immediately after the exercise sessions. The samples were placed in plastic cups and USG was determined with a digital refractometer (ATAGO PAL-10S, Japan) in the training hall by the same researcher each time. USG measurements were carried out after the urine samples were refrigerated to temperature of 20° and UC was classified under LED light condition. As soon as the urine samples were analyzed for USG and classified for urine colour (UC), they were immediately disposed. USG was classified according to suggestion by National Athletic Trainers' Association as hydrated (USG \<1.020) and hypohydrated (USG≥1.020).

Ran from Feb 2025 to primary completion in Feb 2025, 0 months.
Of 65 non-industry interventional studies with no phase under Dehydration, half reached primary completion within 8 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 18. This study's 0 months is below that.
Counting every sponsor, half of 73 studies reached it within 9 months; a quarter within 5 and three quarters within 18.
