In Soccer penalty shootouts, it has been shown that the success rate of kicks varies depending on environmental factors such as the order of kicks and the prestige of the competition. In this study, we focused on the influence of such environmental factors and examined the possibility that leading or not leading situation influenced the success rate. We also attempted to elucidate the background against which this influence occurred. The results did not support the hypothesis that the success rate varied depending on the leading or not leading situation, but revealed that kickers were more likely to aim for the lower goalmouth in situations where they were assumed to feel strong pressure due to environmental factors. It was also confirmed that the success rate was higher when aiming at the upper goalmouth. These results suggest that environmental factors may influence the success rate through which zone (upper or lower) to target.
