IRCT20230622058558N1 IRCT 2023-09-02 Razi University The effect of caffeine on anaerobic performance and fatigue caused by it The effect of different doses of caffeine consumption on EMG activity variables and muscle fatigue index in response to maximal anaerobic test in healthy women 2023-07-22 anticipated 16 Complete https://irct.ir/trial/70926 interventional Randomization: N/A, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Supportive, Blinding description: In each test session, two subjects are present in the laboratory and tablets containing different doses of caffeine in the same dimensions and shapes are given to the subjects by a person other than the subjects and the researcher who knows the dose of the tablets, and the number It records the session and dosage of each subject with date and time. Then, by performing the test protocol, the information is collected and recorded by the researcher. After the completion of all four test sessions and data analysis based on session number and date, each data is attributed to its respective dose. 1-2 This study is conducted on healthy women. Intervention 1: Intervention group: Intervention group: In this research, all the subjects will complete three test sessions (with ten days intervals) in the laboratory by consuming three doses of low, medium and high caffeine. The test protocol is completely similar in all sessions, and each subject is required to perform three 30-second test sessions with 4-minute rest intervals. During the test, the amount of muscle contractions of the right thigh muscles and the lateral width of their upper leg is measured and recorded by an electromyography device. Also, after performing the three-step Wingate test, the maximum voluntary contraction of the muscles mentioned above is measured with rest intervals of 5, 10, 15 and 30 minutes. Intervention 2: Control group: In this research, all the subjects participate in a control session with a pill containing a placebo in addition to the three intervention sessions. All the details of the implementation of the protocol in the control mode will be similar to the intervention mode, with the difference that in the control mode, a tablet containing an ineffective substance (dextrose) will be given to the subjects. Yes - There is a plan to make this available What will be shared: All data can be shared after de-identifying subjects. When: 3 months after printing the results To whom: All people upon official request Conditions: Requesting access to data for any purpose is permitted.
