IRCT20221102056381N1 IRCT 2023-06-24 Shahrekord University Comparison of the effect of exercise training on bone metabolism in adolescent boy Comparison of the effect of 12 weeks of plyometric and HICT training on serum levels of FGF23, KLOTHO, and Some markers related to bone metabolism in adolescent boy 2023-04-30 anticipated 63 Complete https://irct.ir/trial/66701 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Prevention, Randomization description: To reduce the influence of maturity, and to maximize the balance and homogenization of the groups, 63 selected subjects of this research (selected based on the inclusion criteria) were also examined in terms of biological maturity status. Considering the importance of biological maturity in the present research and with the aim of relatively balanced distribution of the subjects in groups, first we stratified the subjects based on the status of biological maturity and using the age of peak height velocity (aPHV) formula. Random allocation software is also used for randomization. In addition to simple randomization, these random sequence generation softwares are capable of generating a random sequence using the block method,that from each block, three subjects were placed in the control group, three subjects in the intervention group 1, and three subjects in the intervention group 2, so that the number of subjects Each group reached 21 people.The advantage of this method is that the distribution of the subjects is done in a more balanced and favorable manner, and it will not be the case that most of the subjects of one group have a significantly higher biological age than other groups. N/A Bone Density. Intervention 1: Intervention group 1: HICT exercise protocol is performed three days a week for 12 weeks. The intensity of the exercises will be gradually increased by using the methods of increasing the training pressure. Intervention 2: Intervention group 2: plyometric exercise protocol is performed three days a week for 12 weeks. The intensity of the exercises will be gradually increased by using the methods of increasing the training pressure. Intervention 3: Control group: They do not receive any kind of training. No - There is not a plan to make this available Justification or reason for not sharing IPD is There is no further information
