Isometric and Isotonic Hand Strengthening in Competitive Female Badminton Athletes

Effects of Targeted Isometric and Isotonic Hand Strengthening on Hand Function, Dexterity, Grip Strength and Grip Endurance in Competitive Female Badminton Athletes

This randomized clinical trial aims to determine the effects of targeted isometric and isotonic hand strengthening exercises on hand function, dexterity, grip strength and grip endurance in competitive female badminton athletes aged 18-30 years. Participants will be randomly allocated into two groups receiving either isometric or isotonic hand strengthening exercise programs performed three times per week for six weeks. Outcome measures will be assessed at baseline, 3rd week and 6th week using Michigan Hand Outcomes Questionnaire (MHQ), Purdue Pegboard Test or Nine-Hole Peg Test, Hand Dynamometer Test and Sustained Grip Test.
