The Effect of Inspiratory Muscle Training on Respiratory Parameters, Balance, Trunk Endurance and Trunk Isokinetic Muscle Strength in Wrestling Athletes

Title: The Effects of Inspiratory Muscle Training on Respiratory Parameters, Balance, Trunk Endurance, and Trunk Isokinetic Muscle Strength in Elite Female Freestyle Wrestlers Objective: This experimental study aims to investigate the effects of inspiratory muscle training on respiratory functions, trunk muscle strength, endurance, and balance in elite female freestyle wrestlers. Methods: This randomized controlled trial will include 30 elite female freestyle wrestlers aged between 16 and 22. Participants will be randomly assigned to either an intervention group or a placebo control group using a simple randomization method. The intervention group will receive progressive inspiratory muscle training with the POWERbreathe Plus device, 5 days per week for 4 weeks. The training load will increase weekly. The control group will undergo low-resistance inspiratory training set at 15% of their baseline maximal inspiratory pressure (MIP), serving as a placebo. Pre- and post-intervention assessments will be conducted by a blinded evaluator.
