The study compared the tactical behaviour and skill efficacy of young novice basketball players during small-sided games (SSGs) in situations of numerical equality (3vs.3), numerical superiority (3vs.2), and a non-scorer floater (3vs.3 + 1). A total of forty-five schoolchildren (11.55 ± 0.49 years) from both sexes with no previous experience in basketball participated in ten four-minute SSGs of each format for four 1-h sessions. The Game Performance Assessment Instrument was used to analyse tactical behaviour and skill efficacy. Friedman’s test, Dunn’s post hoc test, and r effect size were used to compare the variables between SSGs. Pass inefficacy (3vs.3 > 3vs.2; p = 0.004; large effect), rebound efficacy (3vs.2 > 3vs.3 + 1 and 3vs.3; p = 0.002; large effect), support (3vs.3 > 3vs.3 + 1 e 3vs.2; p = 0.002; medium effect), and guard/mark (3vs.2 > 3vs.3 and 3vs.3 + 1; p = 0.001; medium effect) showed significant differences between SSGs. The results support the hypothesis that an unbalanced SSG is less complex than an SSG with numerical equality, as the technical-tactical performance is higher in unbalanced SSGs.

篮球小场比赛中非得分手漂浮物和数值优势对新手战术行为和技术效能的影响

该研究比较了年轻篮球新手在小场比赛 (SSG) 中在人数相等 (3vs.3)、人数优势 (3vs.2) 和非得分手浮动 (3vs.3) 的情况下的战术行为和技能效果。 3 + 1)。共有 45 名以前没有篮球经验的男女学生(11.55 ± 0.49 岁)参加了每种格式的 10 次 4 分钟 SSG,为期 4 次 1 小时。游戏性能评估仪用于分析战术行为和技能效果。Friedman 检验、Dunn 事后检验和 r 效应大小用于比较 SSG 之间的变量。传球无效(3vs.3 > 3vs.2;p = 0.004;大效应),反弹效力(3vs.2 > 3vs.3 + 1和3vs.3;p = 0.002;大效应),支持(3vs.3 > 3vs.3 + 1 e 3vs.2;p = 0.002;中等效果),和守卫/标记(3vs.2 > 3vs.3 和 3vs.3 + 1;p = 0.001;中等效应)显示 SSG 之间的显着差异。结果支持不平衡 SSG 比具有数值相等的 SSG 更简单的假设,因为不平衡 SSG 的技战术性能更高。
