It is often a problem that a lot of pitching is imposed on baseball players in high school age. In this research, we focused on the interval between consecutive pitching, and compared the impact on pitching performance by pitching tasks with different pitching interval. As a result, it was able to suppress to decreasing of the ball velocity significantly between first pitching and second pitching compared the 2 rest days to 1 or no rest day. On the other hand, in all three conditions, the average ball velocity in the second pitching was decreased significantly than one in the first pitching. Therefore, it was suggested that it is necessary to set a rest day at least 2 days after pitching to maintain pitching performance.
