IRCT20220417054556N1 IRCT 2022-07-27 Razi University The effect of transcranial direct current stimulation and dark chocolate on cyclists' athletic and cognitive performance Investigation of the effects of transcranial direct current stimulation and dark chocolate supplementation on athletic and cognitive performance in normobaric hypoxia after inducing mental fatigue in men cyclists 2022-07-23 anticipated 12 Complete https://irct.ir/trial/63130 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Crossover, Purpose: Prevention, Randomization description: In order to randomize the order of subjects' exposure to four different conditions, the Latin square method will be used. To do this, first using the site www.random.org, each subject will be randomly assigned a number between 1 and 12 as the identification code. Then, the English letters A, B, C, and D are assigned to the four intervention terms, and a Latin square with four rows and four columns is created. After creating the Latin square, participants 1 to 3 in the first row sequence, participants 4 to 6 in the second row sequence, participants 7 to 9 in the third row sequence, and participants 10 to 12 in the sequence Sequences will be placed in the fourth row, Blinding description: The subjects and the researcher will not be aware of the type of stimulation received in each session and this information will be available only to someone outside the research team until the end of the research. In order to conceal the order of receiving the stimulus from the researcher, all the steps related to randomly determining the order of receiving the stimulus in each subject will be performed by the same person outside the research team. Also, in order to hide the type of stimulation in each session of the subjects, the tDCS device is hidden from the subjects by a cover and the researcher will not be present in the laboratory during the installation of the electrodes and at the end of 20 minutes and the time of electrode separation. N/A Condition 1: Hypoxia. Condition 2: mental fatigue. Intervention 1: "Intervention group: 2: sham stimulation-dark chocolate, 1: anodal stimulation-dark chocolate." . In both groups of stimulation, after installing the electrodes, the subjects will receive anodal and sham electrical stimulation with a intensity of 2 mA crosswise in a sitting position and one session per week (for 4 weeks) for 20 minutes. Chocolate supplement Bitter (467 kcal of dark chocolate (Nestle-70%) will also be received cross-over each week for four weeks. Intervention 2: "Control group: 1:Anodal stimulation- White chocolate, 2:Sham stimulation-White chocolate." In both groups of stimulation, after installing the electrodes, the subjects will receive anodal and sham electrical stimulation with a intensity of 2 mA crosswise in a sitting position and one session per week (for 4 weeks) for 20 minutes. They will also receive white chocolate supplements ((487 kcal from Nestle white chocolate)) cross-over each week for four weeks.
