概要	This study aimed to examine whether an intervention providing immediate feedback on pitching errors during pitching practice improves pitching accuracy in male semi-professional or college-level pitchers. The research employed a randomized controlled trial involving 12 subjects. A two-way ANOVA was conducted using the immediate feedback of the pitching error as the independent variable and the 95% confidence ellipse area of the pitching error as the dependent variable. The analysis revealed a significant interaction effect. Within the intervention group, a significant simple main effect was observed, with the 95% confidence ellipse area post-experiment being significantly smaller than that pre-experiment.
