The present study examined changes in running speed, step length, step width, step frequency and lower limb joint movements to clarify the footwork maneuver involved in running quickly during tennis groundstrokes for professional female tennis players. The results were summarized as follows: 1) Professional female tennis players reached the hitting point in almost three steps when chasing a tennis ball quickly from the center mark of the tennis court. 2) The increase in running speed from 1st to 3rd step was the result of step length increase. 3) Further development of running speed in each step required improvement of step length and step frequency. 4) Hip extension and leg swing movement were important for running quickly during tennis groundstrokes. 5) The player with high running speed produced high kicking forces by stepping the toe to the outside of the running direction, and as a result, was able to develop step length and running speed.
