초록
The purpose of this study was to investigate the kinematic characteristics of the 5^th and 6^th hurdle clearances during the final of the 100-m hurdles event at the IAAF World Championships, Daegu 2011. To this end, the hurdling motions of the top 4 ranked female hurdlers in the competition were analyzed. A total of 12 cameras were used to record their motions, with a sampling frequency of 120 Hz. The cameras were calibrated using 11 × 2 × 1 m control objects that covered all of the lanes (1^st~ 8^th lanes). After analyzing all the data, we arrived at the following results. For the take-off phase, a negative relationship between the take-off time (CT) and athlete's rank was found. In addition, the average distances from the hurdle to take-off (L1) were shown to be 2.23 m and 2.17 m for the 5^th and 6^th hurdles, respectively. For the distance from the hurdle to landing (L2), Pearson (1^st rank) and Carruthers(2^nd rank) showed inconsistent patterns whereas Harper (3^rd rank) and Porter (4^th rank) showed consistent patterns. All althetes revealed similar 3 steps patterns between hurdles, which consisted of a shorter 1^st step, longer 2^nd step and shorter 3^rd step.
