About this study
Official title: Çocuk Judocuların Antrenör Yönlendirmesi ve Eğitim Müdahalelerinin Hidrasyon Durumlarına Etkisi
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
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hydration-Coach EncouragementBehavioural
Also called Encouragement
Athletes were encouraged by their coaches to consume fluids during the training session.
Short Hydration Informative SessionBehavioural
Also called A brief hydration education
Athletes were given a brief educational session related to importance of hydration before the exercise session.
| Study group | Role | What they receive |
|---|---|---|
| No-intervention (Control) | No intervention | This arm did not receive any intervention. They completed the training session without any encouragement related to fluid intake. |
| Coach encouragement (Intervention 1) | Experimental | During this intervention, athletes were encouraged by their coaches to consume fluids during the training. Receives: Behavioral: Hydration-Coach Encouragement |
| Hydration education (Intervention 2) | Experimental | During this interventio, athletes were given a brief hydration education before the training session. Receives: Behavioral: Short Hydration Informative Session |
What is being measured
The primary outcome is the main question the study is designed to answer.
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).
Measured: 4 days
