The effects of Core Stabilization Vs. Balance-Training Programs on knee proprioception and dynamic balance in healthy female athletes 2022-03-09 anticipated 20 Complete https://irct.ir/trial/61446 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: According to the number of participants in each group, the type of training is written on a piece of paper as " core stability training" or " balance training" and placed in envelopes. Randomly removes one of the envelopes and practice the participant based on the type of the training specified in it. And the envelops are mixed again, Blinding description: The study will be double-blinded. The participants will be blind to the type of intervention in relation to their training group as well as the researcher who must enter the data into the relevant checklist. N/A Healthy female athletes. participants will be randomized to one of two training groups. 1) core stability training group 2) balance training group. The protocol for the core stabilization training program is 3 progressive levels of exercises focusing on strengthening the abdominal low-back, and pelvic muscles while maintaining neuromuscular control. The sets and repetitions and holding times for each exercise for each week are fixed at 3 sets of 20 seconds for isometric holding activities and 20 repetitions for activities with isotonic contractions. Subjects in the intervention group 2 perform a 5-phase balance training program..
