<p>The purpose of this study was to examine the relationship between the levels of proficiency in the straddle and achievement in the squat vault in vaulting box exercise of elementary school children. Participants comprised 239 children (114 boys, 125 girls) in the 5th and 6th grades, each performing straddle and squat vaults while their movements were observed and videotaped from the left and front. The movements of the former were assessed using the observation criterion and proficiency identified through Latent Class Analysis. The level of achievement in the latter was evaluated over three stages: “can jump stably until landing (A),” “can jump over (B),” and “cannot jump over (C).” To determine whether achievement of the squat vault depended on proficiency in the straddle vault, a chi-squared (χ2) test was performed; if a significant difference existed, a residual analysis was conducted.<br>The conclusions of this research were as follows: <br>1.If the movements in the straddle vault consist of a weak takeoff and reliance on the arms to jump over the box, then the squat vault is difficult to achieve.<br>2.If the movements in the straddle vault are stable until landing, then stability is easily achieved in the squat vault.</p>
