There were 2 parts in the experiment in the first part, a camera was used to film the clear, drop, and smash shots performed by a player of international level, and a optical motion capture system was used to collect the kinematics of movements. For the second part, there were 2 groups of participants including 5 expert players and 5 college students of physical education major. Both groups of participants watched 20 clips of the film which were edited to right before the shuttlecock contacting the racket and judged the type of shots made. In addition, both groups of participants also performed clear, drop, and smash shots ten times each for movement analyses. The results show that expert players were superior to the physical major for judging the different types of shots for the forehand stoke performances, both groups demonstrated clear kinematic characteristics at the elbow joint in the preparatory phase of the drop shots for the duration of preparatory phase, there was no significant difference among the three kinds of shots for the expert group whereas the significant effect was found in the group of physical education majors. One general strategy in playing high level badminton game is to withhold the intention of each stroke until the last minute, the skilled player therefore tend nor to reveal any clues for their strokes. The results of study provide further evidence that high level badminton players not only are more sensitive in detecting relevant information, but also perform different types of stroke more consistently during the preparatory phase.
