      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Prevention, Randomization description: After stratified random matching, individuals will be divided into two groups of intervention (Tribulus terrestris supplementation and physical activity; 17 persons) and control (maltodextrin supplementation and physical activity; 17 persons) based on gender and VO2max using RAS software, Blinding description: The intervention group and the control group will consume two capsules of Tribulus terrestris (500 mg) and two capsules of maltodextrin (500 mg) each day respectively for two weeks, which is accompanied by high-intensity interval training. Supplement and placebo will be coded with codes 1 and 2. Until the release of the patient study results, the researcher and data analyzer will not be aware of the assigned codes.</study_design>

      <i_freetext>Intervention 1: Intervention group: The intervention group will consume two capsules of Tribulus terrestris (500 mg) each day, which is accompanied by high-intensity interval training. One of the capsules would be taken after breakfast and the other one would be taken after lunch. To ensure the supplement consumption and follow up the recreational runners' problems, the delivery of unused capsules will be requested at the end of each week. Study subjects will be asked to report any problems too. To apply the exercise protocol, the study subjects will do high-intensity interval training for five days each week (during two weeks). Intervention 2: Control group: The control group will consume two capsules of maltodextrin (500 mg) each day, which is accompanied by high-intensity interval training. One of the capsules would be taken after breakfast and the other one would be taken after lunch. To ensure the supplement consumption and follow up the recreational runners' problems, the delivery of unused capsules will be requested at the end of each week. Study subjects will be asked to report any problems too. To apply the exercise protocol, the study subjects will do high-intensity interval training for five days each week (during two weeks).</i_freetext>
