IRCT20190530043762N2 IRCT 2022-11-21 Shiraz University The effect of plyometric Training on the neuromuscular indicators of athletes The effects of plyometric training with and without additional loads on neuromuscular index and performance in male youth’s soccer player 2022-12-21 anticipated 39 Complete https://irct.ir/trial/65814 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Education/Guidance, Randomization description: Randomization method: Simple randomization Random unit: Individual Randomization Tool: Shuffle Cards Random Sequence Construction Method: The sample selection method will be available in this study and randomly divided into Three distinct groups. Prior to the implementation of the research, 39 young male soccer player (15-17years old) were selected after completing the health questionnaire in physical activity and obtaining personal data. The names of the subjects are recorded on individual cards (each subject has a special card). Then all the cards are thrown in the sphere and are thrown well. After each flipping, a card is removed from the sphere and according to the flipping sequence, they are placed in the control group or intervention 1 or intervention 2. The sequence is that the first card removed is assigned to the control group, the second card removed to intervention 1, and the third card removed to intervention 2. This process is repeated until all the cards are removed from the sphere and assigned to the studied groups. Then completing and registering names in their groups, to hide the process of grouping the subject, through a letter packed with their status in the study and their group will inform the subject. In this letter, the groups are marked with the number and the full description of each group's actions is mentioned. For example, in the closed letter, the first card that out of the ball, are cited the person's activities during the intervention, and the number of his group (group 1), Blinding description: Subjects, instructors, and experts evaluating are kept blind in this study. In relation to the participant, each subject will be informed about the necessary details of their duties as well as their group number in a closed letter. The letter does not mention the group name and only the group number. However, in order to respect the ethics and rights of the subject, all of the tasks and actions that are to be performed are described. People in the control group will be coded with code 1, people in intervention group 1 with code 2, and people in intervention group 2 with code 3. The information about conducting tests and interventions for each group is fully explained and explained and interpreted in a separate meeting for each group. In addition, in order to perform the research plane, 3 coaches were assigned by a closed letter, while explaining all the training and safety issues for each group. Neuromuscular function tests are also performed by technicians and examiners who are fully aware of how to perform the tests. None of the examiners had any information about the intervention status of the subjects. Therefore, in this study, none of the instructors, subjects, and examiners have any information about the status of the subjects (which group is the intervention group and which one is the control group), although the tasks and all the tests and safety aspects will be describe for them. N/A Neuromuscular performance of soccer players. Intervention 1: The intervention group of body weight plyometric training: for 8 weeks/ 2 sessions per week. Intervention 2: The intervention group of additional load plyometric training: for 8 weeks/ 2 sessions per week/ Applying additional load equal to 10% of body weight. Intervention 3: Control group: They will continue their usual football training routine in parallel with the intervention groups. Yes - There is a plan to make this available What will be shared: All the data collected in the present study about the neuromuscular indicators as well as the individual characteristics of the participants can be shared with researchers. When: Start accessing the data immediately after the results are published To whom: Academic researchers Conditions: For the purpose of follow-up or meta-analysis studies Where to obtain: Shiraz University, Department of Sports Sciences, Dr. ‪Maryam koushkie Jahromi How to obtain: Sending the application and providing the necessary documents for employment in one of the reputable scientific centers to the email address Koushkie53@yahoo.com.A response will be sent one week after submitting the request.

Timepoint: Before and after the intervention (Exercise training). Method of measurement: The maximum isokinetic force as well as the rate of force development will be measured using the Biodex isokinetic dynamometer when performing knee flexion and extension tasks. Neuromuscular efficiency. Timepoint: Before and after the intervention (Exercise training). Method of measurement: Using the surface electromyogram of the knee extensor and flexor muscles during the isometric maximum strength test of knee extension and flexion. Explosive power of lower body muscles. Timepoint: Before and after the intervention (Exercise training). Method of measurement: Using the Sargent vertical jump test on the Ergo-jump machine.
