The purpose of this study was to identify the typical motor patterns of Basic Vaulting-Box movement (straddle-vault) for elementary school children based on observational evaluation, and to discuss the teaching points according to their proficiency levels. The subjects were 453 children (220 boys, 233 girls) from the 3rd-6th grade. They performed a straddle-vault and then motions were recorded from the left and front side. The motions were scored by the evaluation criterion made from descriptions in prior researches and movements of elementary school children and university students. Latent Class Analysis (LCA) was used to extract characteristic motions based on the response patterns to the criterion.
The results were summarized as follows:
1 ．The observational evaluation criterion of straddle-vault comprised 30 items was created from consideration of the motion causality.
2 ．Children's straddle-vault motions were categorized into five patterns: Failure vaulting, Arm dependent vaulting, Landing unstable vaulting, Stable vaulting and Strong push-off vaulting.
3 ．From the viewpoint of success or failure of the vault, achievement rate rises as the grade increases.
4 ．From the viewpoint of performance of the technique, it can not be said that high proficiency movements will increase with progress of grade.
