コロナ禍における大学女子バレーボールチームを対象としたインカレ優勝までの過程

抄録

    The purpose of this study was to overview how the local university women's volleyball team was affected by the global outbreak of the COVID-19 infection and how they responded to it, and to clarify the process of winning the intercollegiate tournament.
    A single-case design adopted as the method, and game performance items were collected. The tau-u test was used for statistical processing, and the significance level was set at less than 5％.
    The results showed that the number of service ace (Tau-u＝0.64, p＝0.05) and reception return rate (AB) (Tau-u ＝0.82, p＝0.011) increased in the university.
    The university had been practicing with the intention of scoring and breaking down by serving. The university improved because they aimed to strengthen the serve and receive, which can be practiced with limited time and fewer people.
    Furthermore, the university showed an increase in the number of attack points (Tau-u＝0.69, p＝0.03), the total number of back attacks (Tau-u＝1.00, p＝0.00), and the number of back attack points (Tau-u＝1.00, p＝0.00), increased in the match phase compared to the baseline phase. The university realized on the first day of the reinforcement match (October 3) that using the back attack was effective, and implemented it the next day. This suggests that the number of back attack decisions and spike decisions increased by increasing the number of attackers and increasing the uncertainty of the opponent's defense.
