This study used computer simulations to analyze the motion of a ball in a ladder getter setup, using a Lagrangian formulation to determine how variations in ladder installation distance and target bar height influence the ball's ability to hang on the ladder. The findings demonstrate that performing the ladder getter is a complex motor task with specific release conditions that must be met for the ball to successfully hang on the bar, requiring adjustments in the throwing technique. The results showed significant differences in the number of successful trials under different target conditions, with closer ladder installation and higher ladder placement leading to an increased number of successful attempts. The number of successful trials for each variable varied for each target condition, suggesting that the combination of variables in the interquartile range facilitated more successful throws. Analyses of median differences revealed significant main and interaction effects of ladder distance and bar height on the release position, initial velocity, projection angle of the ball, and string angle, with significant differences observed across all target conditions. Additionally, the number of successful projection angle combinations tended to decrease as the ball's initial velocity increased in each target condition. These results indicate that the ball's ability to hang is significantly influenced by its initial velocity and projection angle at the time of release, making the adjustment of these factors critical for throws targeting specific ladder distances and bar heights. Based on these findings, it is suggested that providing participants with support that clarifies specific ball release conditions and allows them to observe actual successful trials would effectively enhance their understanding and help them experience the most enjoyable aspects of the ladder getter as soon as possible.
