 note = {From 1960’s, sports activities, such as Junior Sport Clubs Association and private sports club for elementary school age has been expanded. The purpose of this paper was to clarify the impact on junior high school extra-curricular club activities caused by the expansion of sports activities among elementary school age. Through analyzing the data acquired from questionnaire survey for junior high school teachers, we got the following results. 1. When looking at the athletic club as a whole, the clubs with few experienced students account for about 30 to 40%. However, there are about 20% of the clubs where almost all of them are made up of experienced students. And the clubs consisted by more experienced students practice more frequently and the participation frequency of practice games tend to be overheated. 2. The number of experienced people depends on the kind of sports, and there are many experienced students especially in baseball and soccer. There are few experienced players in badminton, tennis, “track and fields” and table tennis. The sports in which the more experienced students participate is likely to practice more frequently. From this result, it can be inferred that the expansion of sports opportunities at the elementary school level has increased the number of people already skilled at the time of entering junior high school, which has led to overheating. 3. However, even in the kind of sports with few experienced people, some clubs have many experienced students. As long as there are a lot of experienced people, there is a tendency to participate in high-level competitions. However, only in the case of baseball and soccer, practice time and practice game frequency correlate with the percentage of experienced players. In other kind of sports, there is no correlation between the number of experienced students and the time of activity or practice game frequency. For baseball and soccer, it is more common to experience in elementary school and then continue it in the junior high school sports club. This may have increased the impact of elementary school level experience not only on competition results but also on practice time or practice game frequency. Based on the above results, the importance of focusing on the continuity of sports from elementary school level to junior high school level was discussed.},
