説明

The purpose of this study was to develop the useful statistical data indexes to evaluate the team performance of attack and defense during handball match. The subject of analysis in this study were 216 matches of Japan Handball League in 2017-2018 and 2018-2019 seasons and 145 matches of Handball-Bundesliga in 2018-2019 season. We calculated the ratio of goal, free throw, turnover against the possessions to make an index of expected goal (xG)，expected received free throw (xRTF) and expected turnover (xTO) in attack phase. Similar, expected opposing goal (xL), expected taken free throw (xTTF) and expected opposing turnover (OppxTO) were calculated in defense phase. Also, shot efficiency (%G) and opposing shot efficiency (%L) were calculated. As a results of multiple regression analysis, we found that %G, xTO and xRTF in attack phase and %L, OppxTO and xTFT in defense phase were important variables to evaluate the team performance. In conclusion, %G, xRTF and xTO in the attack phase and %L, xTTF and OppxTO in the defense phase are important indexes for evaluating the team performance and these are very useful statistical indexes for real-time analysis during the match.
