When coming off the blocks at the start of a sprint running race, the athlete accelerates from a static state to maximum sprinting speed. Therefore, knowing how to increase power off the starting block is important. In the present study, the forces applied to starting blocks by sprinters were measured. From starting blocks, six sprinters did the "starting dash" as is done in a sprint running race, and the forces applied to the right and left starting block as well as to the ground during the first step were measured with force plates. As a result, no large difference was observed between the sprinters in terms of the force applied to the back block. However, the force applied to the front block differed between the sprinters, suggesting that the force applied by the front foot possibly affects performance during the "starting dash". Moreover, the force applied to the ground during the first step indicated that there is a possible relation between the forces of the first step and the force applied to the starting block by the front foot. In addition, it was observed that the sprinters applied a force in the right or left direction when the foot struck the ground. Considering these results, further investigation of the effects of step width is necessary.
