IRCT20200228046632N1 IRCT 2020-03-09 University of Tehran The effect of high intensity circuit training on two muscle growth factors Effect of High-intensity circuit training on serum Myogenin and Myostatin adolescents soccer players 2018-12-23 anticipated 21 Complete https://irct.ir/trial/46199 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Other, Randomization description: Randomization was performed in this study by a simple method, individually and by lottery method. In this study, subjects were randomly divided into experimental and control groups. Before the intervention, 22 adolescent boys aged 14 to 16 years were selected after completing a physical activity questionnaire and demographic data. The subjects' names were recorded on separate sheets and placed in a draw. After each time the cards were shuffled, one card was randomly assigned to the experimental group and the control group according to the number of each subject, with the individual numbers in the control group. Then, so that the odd numbers in the control group and the even numbers were put in the experimental group. To hide the subject grouping process, we informed each subject by a letter of their group status, Blinding description: In this study, subjects and evaluators of field and laboratory tests were kept blind to study groups. About the subjects, we informed each subject in the form of a confidential letter about all the tasks and their grouping requirements. We reported the status of the subject grouping through the code selected for each group (exercise group (1) and control group (2)) and no group names were recorded in the subjects' letters. Also the field and laboratory receiver tests did not know about the status of the subjects. N/A Impact of exercise protocol. Intervention 1: Exercise group: High-intensity circular exercises. This training protocol consists of 8 stations including 20m sweep, Swedish swim, Scott Jump, Planck Jack, Nordic, Climbers, high Knee, and Burpee. Between each station, the subjects rested for 1 minute in the first 2 weeks and 30 seconds in the following weeks. Subjects performed these exercises 3 times a week for 8 weeks. These exercises were performed in the first four weeks at 80% of the subjects' maximum heart rate. During the second four weeks, subjects were administered 85 to 90% of their maximum heart rate. Intervention 2: Control group: Control group subjects performed their normal football training routine. Subjects in this group, like the training group, performed their soccer training for 8 weeks, 3 sessions a week. Yes - There is a plan to make this available What will be shared: All information obtained from biochemical tests of each subject on the basis of individual numbers can be made available to valid researchers. When: 12 months after publication of research results To whom: Authentic academic researchers Conditions: For the purpose of follow-up, review and meta-analysis studies Where to obtain: University of Tehran - Dr. Mohammad Reza Kurdi How to obtain: First, the required documentation for teaching employment at one of the universities approved by the Ministry of Science and Technology of the Islamic Republic of Iran is sent to the following e-mail address: A.ziyaiyan74@ut.ac.ir. The candidate is sent to submit a brief report on how to conduct his / her research. Then, if the researcher in charge of this study, Dr. Mohammad Reza Kurdi agrees, all the information required in a file will be kept confidential, including the names, contact numbers, addresses, and personal information of the selected researcher. This process also takes a week. Comments:
