The research group followed up 469 junior high school students from the 1st grade to the 3rd grade, and the lowest and highest grades of physical fitness (whole body endurance), weak subjects, and academic performance of strong subjects (Japanese, math, science, social, and English). The change in value) was investigated.At that time, parents' educational background, household income, and after-school study time, which affect their academic performance, were statistically excluded.

　According to it, it was found that the improvement of physical fitness was not related to the change in the academic performance of the subjects that were good at, but the grades of the subjects that were not good at it were improved.It is not clear why the positive effect was produced only in the subjects that were not good at it, but the research group had a positive effect on the subjects that they were not good at and the negative effect on the subjects that they were good at. Focusing on the points that have not been released, we will continue the analysis.

　The relationship between physical fitness and academic performance of children has been actively studied over the past 15 years, but the views of each study are inconsistent, and no conclusion has been reached regarding the relationship between physical fitness improvement and academic performance.Therefore, the research group tried to clarify the relationship by analyzing the academic performance by dividing it into the subjects that it is good at and the subjects that it is not good at.
