Abstract
Purpose : The purpose of this paper is to figure out the effects of the Powerball exercise on grip strength, tip pinch and key pinch. Methods : Twenty subjects participated in this experiment. Spin right wrist counterclockwise for five minutes holding Powerball after making main joint of right hand -predominant hand- into elbow flexion and forearm pronation. Results : 1. Before and after Powerball exercise, when we compared the grip strength of men and women, there was a significant difference. 2. Before and after Powerball exercise, when we compared tip pinch of men and women, there was a significant difference. 3. Before and after Powerball exercise, when we compared key pinch of men and women, there was a significant difference. 4. Before and after Powerball exercise, there was no significant difference between men and women. Conclusion : From what using Powerball exercise influenced grip strength, tip pinch and key pinch positively, we assume that it will be considered a great expectation to improve grip strength, tip pinch and key pinch in the future and it would be better to conduct this experiment in depth to a lot of people.
