The purpose of this study was to analyze the attacking actions of world elite Taekwondo contestants in Beijing 2008 Olympic Games. The attacking actions and the contestants' backgrounds were categorized and analyzed to determine if there were differences of attacking actions among Taekwondo contestants in this study. The subjects of the study included the 62 contestants who were in the female weight divisions of -49kg, female -57kg, male -58kg, and male -68kg. Video Observation Analysis was utilized to analyze all the attacking actions of the 62 contestants. All the data of the attacking actions recorded by the 3 professional international Taekwondo coaches were verified by internal consistency method. Then the descriptive statistics and Pearson's chi-square test were employed to analyze the statistics to find out the differences of influencing attacking actions. The results of showed that first, there were significant differences (p <.05) between the competitors’ attacking types and their gender/height/age/region; second, the attacking actions of male contestants were more diverse than the attacking acts of female contestants; third, the contestants that were shorter in height relatively to their opponent, tended to use defensive attacking actions, employed more short-distance attacking actions than contestants that were relatively taller in height than their opponents; forth, the roundhouse kicks of the contestants among 18-20 years old were used about 66% of the time; fifth, European contestants employed the greatest variety of attacking actions while Asian contestants employed the smallest variety of attacking actions. We concluded that height was a factor in determining attacking actions and that males employed a greater number of strategies. Regarding regional differences it is possible that Asian traditions require perfecting attacking strategies evidenced by the use of fewer types of attacking actions as opposed to Europeans developing a greater range of attacking actions but perhaps not as proficiently which should be a topic of future research.
