Sažetak
The ability to punch with both hands is regarded as a desirable skill in high level taekwondo athletes ; however, most athletes display a dominance of one side of the body relative to another. Therefore, the two main objectives of this study are presented: 1) to determine whether there is a difference in maximum punch velocity between dominant and non-dominant hand, and 2) to determine whether there is a difference in the punch accuracy between dominant and non-dominant hand. Forty- two taekwondo athletes were measured by Punch system which is specially designed to measure the velocity and accuracy of a punch. Differences between the punch accuracy of a left and right hand, and difference between punch velocity of a left and right hand were determined by univariate analysis of variance. The average punch velocities were 8.08 m/s (± 2.39) and 6.73 m/s (± 1.67) for the right and left hand, respectively. Average punch lengths, as a measure of an accuracy, were 50.81 cm (± 3.74) and 51.24 cm (± 5.11) for the right and left hand, respectively. By univariate analysis of variance it was determined that there was a difference in punch velocities (F1, 82 = 8.85, p < .01) between right and left hand. There was no difference between the punch accuracy of a left and right hand (F1, 82 = 0.19, p = .662). The findings of this study suggest that each limb is specialized in controlling various features of the movement: the dominant side to control the punch velocity, while the non- dominant side is responsible for controlling the position of the limb, i.e. the focus of the punch.
