| The purpose of this study was to determine if differences exist between dominant and nondominant knee extension angular velocities for beginner, intermediate and advanced students performing the Taekwondo Front Snap Kick (FSK). Forty-two Taekwondo students were videotaped performing three right leg and three left leg chin-level FSK. Subjects were placed into three groups according to number of months of training: beginner (G1), n = 9, 3.0 ± 2.88 months, intermediates (G2), n = 9, 13.33 ± 3.39 months, and advanced (G3), n = 24, 56.21 ± 060.44 months. Subjects completed an Edinburgh Inventory to determine dominant side.;Video tapes were digitally encoded and manually digitized using a Peak Performance Technologies 2D motion analysis system. Raw data points were smoothed with a Butterworth digital filter set at 6 Hz. Maximum knee extension angular velocities were calculated for each kick. Average of right and left leg kicks were used for analysis. Results for the dominant side for G1, G2 and G3 were 956.49 ± 168.61, 996.93 ± 209.44, and 1086.62 ± 165.04 degrees per second, respectively. (Abstract shortened by UMI.). |
