Design outcomes

Primary

MeasureTime frame
The level of lactate dehydrogenase in a blood sample taken after an exhaustion test. Timepoint: The amount of lactate dehydrogenase will be measured in two stages: at the beginning of the study before starting the supplement after performing the exhaustion test, and at the end of the study after taking the supplement for one month and after performing the exhaustion test. Method of measurement: Blood samples for lactate dehydrogenase measurement will be collected after 10 to 12 hours of fasting. After blood sample collection, the tubes are placed at room temperature for 30 minutes to allow clot formation, then centrifuged at 3000 rpm for 10 minutes, and the serum fraction will be separated and stored in special microtubes at -80°C until analysis.;VO2max value for endurance runners. Timepoint: The VO2max value will be measured in two stages: at the beginning of the study, before starting the supplement, after performing the exhaustion test, and at the end of the study, after taking the supplement for one month and after performing the exhaustion test. Method of measurement: The VO2max test will be performed by performing a shuttle run test in the form of a 20-meter route using a recorded tape. The test ends when the person is 3 meters or more away from the lines or the line twice after hearing the beep. The test speed will be 8 km/h in the first stage and 9 and 9.5 km/h in the second and third stages. From now on, the speed will increase by half a kilometer per hour in each stage and from stage 21 to 23 the speed will be 18.5 km/h. Maximum oxygen consumption = age × speed × 0.1536 + age × 3.248 - speed × 3.238 + 31.025 Speed ??is the speed at which the test is completely completed and age will be in years.;Pain score after performing the exhausting test. Timepoint: Pain levels will be measured in two stages: at the beginning of the study, before starting supplement use, after performing a depletion test, and at the end of the study, after taking the supplement for on

Secondary

MeasureTime frame
Weight. Timepoint: At the beginning of the study and after 4 weeks of starting to take the sumac supplement. Method of measurement: The weight of patients without shoes and with minimal clothing is measured using a Seca scale with an accuracy of 0.1 kg.;Height. Timepoint: At the beginning of the study and after 4 weeks of starting to take the sumac supplement. Method of measurement: The height of the study subjects will be measured using a tape measure mounted on the wall with an accuracy of 0.1 cm.;Body Mass Index (BMI). Timepoint: At the beginning of the study and after 4 weeks of starting to take the sumac supplement. Method of measurement: Body mass index (BMI) will also be calculated based on the relationship between weight (kilograms) and height (meters) squared, i.e. the formula Weight(kg)/(height(m))².;Body composition. Timepoint: At the beginning of the study and after 4 weeks of starting to take the sumac supplement. Method of measurement: Body composition will be measured using a Tanita body analyzer.;Appetite. Timepoint: At the beginning of the study and after 4 weeks of starting to take the sumac supplement. Method of measurement: To determine appetite, a five-point questionnaire based on a Likert scale (with a response range from 0 to 10) whose validity and reliability have been previously determined will be used.;Waist circumference (WC). Timepoint: At the beginning of the study and after 4 weeks of starting to take the sumac supplement. Method of measurement: The participants' waist circumference will be measured using a anthropometric meter, midway between the lower edge of the lowest rib and the upper edge of the iliac crest, after exhalation.;Hip circumference (HC). Timepoint: At the beginning of the study and after 4 weeks of starting to take the sumac supplement. Method of measurement: The circumference of the hips will be measured using a anthropometric meter at the area of ??greatest curvature of the hips.;Energy received. Timepoint: At the be
