概要	This research studies optimal swimming movement, specifically it focuses on the optimal kick timing during dolphin style swimming. In the rule of Breast Stroke Style, it is allowed to hit one dolphin kick during underwater movement. Until December 2014, we couldn’t do dolphin kick before hands start to move. Now, dolphin kick can be performed at any time by the rule amendment. In this research, we modeled this style of movement and searched for optimum timing of dolphin kick. We used computational simulation model called SWUM (SWimming hUman Model). From the simulation results, we got the conclusion that we should do dolphin kick 0.4 seconds faster than hands move. In addition, we indicate the timing affects the body posture. These results agree with the current top swimmer’s timing.
