The research field of motor skills has become wider and wider. This paper, based on different organization levels; took 107 students from Inner Mongolia Normal University as research subjects for two events, Wushu and swimming. The research result shows that the motor skills maintenance curve for Wushu comes in “M” shape with its relatively low organization level, while the curve for swimming is in “W” shape, for its relatively high organization level. And as to the acquisition of motor skills of different organization levels, the group with a high learning level maintains much better than group with a medium or a low learning level, and the discrepancy is quite apparent.
