2011 대구세계육상선수권대회 남자 장대높이뛰기경기우수/준우수선수 경기기술의 운동학적 요인 비교 분석 = Kinematical Analysis of 2011 Daegu IAAF World Championships Men`s Pole Vault Event

다국어 초록 (Multilingual Abstract)

The purpose of the study was to investigate the relationship between the different kinematical variables with respect to the records and techniques performed by the participants during the 2011 Daegu IAAF World Championships Men``s Pole Vault Event. Subjects chosen for the study were 8 male athletes who were selected for men’s pole vault finals (highly skilled group) and 7 athletes who scored lowest record (skilled group) from the men’s pole vault qualifying round. Personal best record of the each subjects were chosen to perform two dimensional (2D) and three dimensional (3D) video analyses. The data were obtained at 60 Hz with the use of five video cameras and digitizing was performed. Kinematical variables were calculated after smoothing the data using 2nd order Low-Pass Butterworth filter at cut-off frequency of 10 Hz and Independent samples t-test was performed to test any differences between two subject groups. The results: during the run-up stage, the horizontal velocity rate of the number of steps and run-up phase was obtained higher in highly skilled group than skilled group. During the take-off phase, deceleration in the horizontal velocity rate was observed in highly skilled group than skilled group. Distinct technical characteristics of distant and lower take-off of the take-off angle (angle of pole support) were also observed in highly skilled group than skilled group. During the pole bending and releasing phase, horizontal velocity was generally higher in highly skilled group than skilled group. It is considered that highly skilled group was able to jump higher as the vertical velocity during the pole bending as well as release phase was much higher in comparison to the skilled group.
