      <study_design>Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: The samples studied in this study will be randomly assigned to patients in the studied groups (sport intervention and electrical stimulation intervention). Samples were assigned to randomly assigned random sampling block permutation to the two groups of study. Thus, the study will continue until the number of samples has been completed. To implement this randomization method, the following procedure is performed:
1. The total sample size and sample size ratio were determined in the groups.
2- Single digit numbers between 0 and 9 will be selected from random numbers table.
3- For studies with 2 groups, the numbers from 0 to 9 will be divided into two equal blocks, with the probability of allocating one to each block will be 0.5. Block 4-0 for the first group and block 9-5 for the second group will be used. Based on the selected numbers from the random number table and the determination of the blocks, it will be determined which group to be included in the study.</study_design>
