Analysis the Kinematic and Muscular Activities in Arm Wrestling: Role of Pectoralis Major and Flexor Carpi Ulnaris in Arm Wrestling

Abstract

The objective of this study was to facilitate a concrete review of the kinematic characteristics muscular activities performed in arm wrestling. In this analysis, 12 healthy male volunteers were recruited. Pectoralis major (PMJ) displayed slightly greater muscle activation in winning condition than in losing position (p=.039), had a substantial effect on the arm wrestling result (p<.01), but did not effect on the other three muscles. The flexixor carpi ulnaris (FCU) of the winners displayed higher muscle activation than the losers. Our research found that PMJ was an essential muscle in arm wrestling, FCU may play a crucial role in arm wrestling in order to obtain an advantageous place.
