| 收集 CBA 联赛2019-2020赛季和2020-2021赛季中对阵相同的834场常规赛的13项篮球技术指标数据,采取 T 检验、多元线性回归等方法进行综合分析,研究空场比赛条件下 CBA 联赛各项技术指标的变化情况及其与比赛得分的相关性。结果显示,空场比赛会导致主场效应减弱甚至消失。与非空场比赛相比,空场比赛条件下有7项技术指标存在显著或极显著差异,其中降低的有罚球命中率、灌篮、得分和失分,提高的有助攻、失误、抢断。CBA 球队各项技术指标对球队得分的重要性在空场比赛时发生了变化,但最影响 CBA 球队得分的3项技术指标没有发生改变,依次为两分球命中率、三分球命中率和进攻篮板。分析认为,空场比赛条件下运动员的表现欲望和积极性不高, 导致比赛的激烈程度有所下降。建议对运动员心理进行更有效的调整和干预,使之能够很好适应空场比赛条件;及时根据空场比赛环境变化及影响球队得分的技术指标,科学制定应对策略;为创造良好的比赛氛围,还可考虑引入云观众、增强远程互动等措施。 |
