This study was designed to explore the variation of reaction time of the sportsmen engaged in different sports items by using different sports items by using different response parts to manipulate the stimulus-response compatibility. The experiment participants (N=41) were all those who are used to using right hands. There were three groups inclusive of Experiment Group I, Experiment Group Ⅱ, and Control Group. The reaction time of each participant was measured by suing the TAKE’I’s “Discrimination Reaction Test of Multiple performance Type”. The experiment data was statistically examined by the mixed design of 3-Way Analysis of Variance (one independent sample and two dependent samples). The result state below: 1. Sports items, compatibility and response parts all made an influence on reaction time. These three variances interact with one another. In terms of the left-hand RT in Experiment Group I and Experiment Group II, those containing compatibility were superior to the ones without compatibility. And in terms of the left hand RT and the right hand RT in the Control Group, those containing compatibility were superior to the ones without compatibility. In regard to the right hand RT of compatibility and the left hand RT without compatibility, Experiment Group I is superior to Experiment Group II. In terms of RT, the groups without compatibility was slower than Group I, Group II, and control Group, which all have left hand compatibility. And in the same way, in terms of RT, the Control Group containing right hand compatibility was faster than those without compatibility. In addition, regarding Experiment Group I and Experiment Group II containing no compatibility, the right hand RT was faster than that of left hand. 2. The existence of compatibility in different sports items and response parts (in different sports items) both influence reaction time; however, both posses had no interaction relation. 3. The existence of compatibility and different response parts both influence reaction time, and interact with each other. The left hand RT of compatibility was faster than the right hand RT without compatibility. And left hand RT of compatibility was faster than the right than that of left and right hand without compatibility. 4. Different sports items and response parts made no significant difference in terms of their influence on reaction time. 5. The existence of compatibility made a significant influence on reaction time. The average RT of those with compatibility was faster than that without compatibility.
