Postural Stability and Trunk Strength in Wrestlers

The goal of this observational study is to evaluate the relationship between sagittal plane isokinetic trunk strength and dynamic postural stability in elite wrestlers compared to healthy sedentary volunteers (males, aged 18-30). The main questions it aims to answer are: Is there a significant correlation between maximal concentric isokinetic trunk torque/power values and dynamic postural stability variables in elite wrestlers? How do the agonist/antagonist (flexion/extension) ratios and core strength profiles of elite wrestlers differ from those of a sedentary control group. Comparison Group: Researchers will compare elite wrestlers (with at least 5 years of professional experience) to a healthy sedentary control group to see if professional wrestling training leads to superior trunk muscle integration and enhanced dynamic balance control.Participants will:Complete a demographic data form and a health screening to ensure they meet the inclusion/exclusion criteria (e.g., no history of spinal surgery or acute back pain).Perform a standardized warm-up session on a cycle ergometer at 55-60 rpm.Undergo dynamic postural stability testing to measure balance control and center of gravity displacement.Perform isokinetic trunk strength testing (flexion and extension) to measure peak torque, total work, and power values relative to body weight (PT/BW).
