The aim of the study was to determine the impact of boxing experience on shoulder internal rotators concentric and eccentric strength of amateur male boxers. Forty amateur boxing athletes participated voluntary in the study. Measurements of internal rotators concentric and eccentric strength of both shoulders were done under static conditions on a Kin-ComTM (Chattecx, Chattanooga, TN) dynamometer at angular velocities of 60, 120 and 180ο/sec. One way analysis of data revealed the following significant differences: At 60ο/sec: Between boxing experience and shoulder internal rotators concentric and eccentric strength both in dominant arm (p<0.001& p<0.03 respectively) and in non-dominant arm (p<0.03&p<0.04). At 120ο/sec: Between boxing experience and shoulder internal rotators concentric and eccentric strength of the dominant arm (p<0.001 and p<0.005). At 180ο/sec: Between boxing experience and shoulder internal concentric and eccentric contraction in dominant arm (p<0.016 and p<0.019). Post hoc corrections with bonferroni method revealed: At 60ο/sec: Boxers who had experience more than 10 y had greater shoulder internal rotators concentric and eccentric strength in dominant hand, in relation to athletes with experience 5 y (p<0.002 and p<0.04). Boxers who had experience more than 10 y had greater shoulder internal rotators concentric and eccentric strength in non-dominant arm, in relation to the athletes with experience 5 y (p<0.002 and p<0.005).At 120ο/sec: Boxers who had experience more than 10 y had greater shoulder internal rotators concentric and eccentric strength in dominant hand, in relation with the athletes with experience 5 y (p<0.001 and p<0.05).At 180ο/sec: Boxers who had experience more than 10 y had greater shoulder internal rotators concentric and eccentric strength in dominant hand, in relation with the athletes with experience 5 y (p<0.017). It is concluded that the boxing experience has positive effects on shoulder internal rotators concentric and eccentric strength of amateur male boxers.
