IRCT20180626040244N1 IRCT 2020-11-21 Allameh Tabataba'i University effects of 6-week corrective-plyometric training with and without visual feedback on dynamic knee valgus effects of 6-week corrective-plyometric training with and without visual feedback on lower extremity Biomechanics and dynamic balance in junior female athletes with dynamic knee valgus 2020-10-13 anticipated 26 Complete https://irct.ir/trial/51244 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Prevention, Randomization description: After screening, by simple randomization participants will be divided into 3 groups of control (8 participants), exercise (8 participants), and feedback (10 participants). The randomization is going to be done by random numbers chart, by considering numbers between 0 to 8 for control group, 8 to 16 for exercise group, and 16 to 26 for feedback group. The researcher will choose one of the numbers and move through a previously determined direction and register the number and give it to the related group, Blinding description: In this study, the assessor (who is the researcher) is blinded to the participants' information (single blinding), and the results of participants tests are analyzed based on participants' given number and without knowing their names. That information includes participants names, and weight, height, and age information. N/A Dynamic knee valgus. Intervention 1: Intervention group 1: This group will practice 6 weeks of plyometric-exercises with visual feedback during the exercises from a mirror in a sports gym. Each week includes 3 sessions of practice which takes 30 minutes. Exercises include squats, balance training, and jump-landing exercises. Intervention 2: Intervention group 2: This group will practice 6 weeks of plyometric-exercises without any visual feedback during the exercises, in a sports gym. Each week includes 3 sessions of practice which takes 30 minutes. Exercises include squats, balance training, and jump-landing exercises. Intervention 3: Control group: This group will not receive any exercises from the assessor and continues their daily routine activities. Yes - There is a plan to make this available What will be shared: After publication, the data which will be also presented in the article, will be given to the researchers in Excel format which includes the pre and post interventions' results of landing tests' biomechanical analysis and dynamic balance, for future studies like meta-analysis studies. When: After publication To whom: The published data of the current study will be accessible for the researchers in the academic institutes and universities, and also people who work in the industry. Conditions: After publishing the article, the data will be used in future researches, like meta-analysis or other types of researches.
