Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Thirst evaluation questionnaire will be done at the beginning of the trial and after the end of the study period using the thirst evaluation questionnaire and visual analog scale (VAS) 10 cm self-rating, where zero means no desire to consume liquids and ten means It means extreme thirst.The volunteers' fatigue assessment questionnaire will be completed by the volunteers at the beginning of the trial (minute zero) and after the study period.The volunteers' urine samples will be taken at 0 (before the start of running), 45, 70, 95 and 120 minutes during the trial and will be collected in urine sample containers for analysis. The color and specific density of urine will be measured visually and using a digital refractometer at the mentioned time intervals. Timepoint: The test will be conducted in controlled conditions (temperature 35°C, relative humidity 30% and cooler temperature 26°C) on a treadmill for 45 minutes.Urine samples of volunteers will be taken at 0 (before the start of running), 45, 70, 95 and 120 minutes during the trial and will be collected in urine sample containers for analysis.Volunteers' blood samples will be taken at 0, 45, and 120 minutes during the trial, and blood analyzes will be performed including measurement of plasma volume and hematocrit.The heart rate of the volunteers will be measured at 0, 45, 70, 95 and 120 minutes during the trial period. Thirst evaluation questionnaire at the beginning of the experiment and after the end of the study period will be completed by the volunteers using the thirst evaluation questionnaire and the fatigue evaluation questionnaire of the volunteers at the beginning of the experiment (zero minute) and after the study. Method of measurement: Fatigue and thirst questionnaire, refractometer and blood tests to check the specific density of urine. | — |
