To evaluate external and internal training load (TL) and hormonal responses in basketball 3-versus-3 small-sided games (SSGs).
Randomized repeated-measures study.
Twelve male basketball players participated to four 3-versus-3 SSGs characterized by different tactical tasks (offensive; defensive) and training regimes (long-intermittent: three 4-min bouts with 2' rest in between; short-intermittent: six 2-min bouts with 1' rest in between). Variables measured were: PlayerLoad (PL); percentage of maximal heart rate (%HR); Edwards' TL. Before and after the SSGs, saliva samples were collected to measure cortisol (C) and testosterone (T). Two-way (task; regime) repeated-measures ANOVA was performed for PL and %HR; C concentrations were analysed with a three-way (task; regime; time: pre/post) repeated-measures ANOVA; non-parametric analyses were performed for Edwards' TL and T.
PL was moderately higher in offensive task (148.0±16.8 AU) compared to defensive (137.1±15.5 AU), and short regime (147.0±18.2 AU) compared to long (137.9±14.6 AU). %HR was moderately higher in offensive task (91.1±4.1%) compared to defensive: (88.7±5.4%), while it did not differ between regimes (long: 90.0±5.6%) (short: 89.8±4.2%); additionally, an interaction (task*regime) effect was found (ES: strong). Edwards' TL was moderately higher in offense-long SSG (56.6+2.4 AU) compared to defense-short (52.4+4.4 AU). C increased after the SSGs (ES: strong). T decreased after offense-short (ES: moderate) and increased after defense-long (ES: moderate) SSGs.
Tactical tasks and training regimes influence external and internal demands of basketball SSGs. Steroid hormones respond in SSGs.
评估篮球 3 对 3 小场比赛（SSG）的外部和内部训练负荷（TL）和激素反应。
随机重复测量研究。
12 名男性篮球运动员参加了 4 场 3 对 3 SSG，这些 SSG 的特点是战术任务（进攻；防守）和训练模式（长时间间歇性：3 个 4 分钟的回合，中间休息 2'；短时间间歇性：6 个 2 分钟的回合，中间休息 1'）不同。测量的变量包括：运动员负荷（PL）；最大心率百分比（%HR）；爱德华兹 TL。在 SSG 前后，采集唾液样本以测量皮质醇（C）和睾酮（T）。对 PL 和 %HR 进行了两因素（任务；模式）重复测量方差分析；使用三因素（任务；模式；时间：前后）重复测量方差分析分析 C 浓度；对爱德华兹 TL 和 T 进行了非参数分析。
与防守任务（137.1±15.5 AU）相比，进攻任务（148.0±16.8 AU）的 PL 略高，与长时间间歇模式（147.0±18.2 AU）相比，短时间间歇模式（137.9±14.6 AU）的 PL 略高。与防守任务（91.1±4.1%）相比，进攻任务的%HR 略高（88.7±5.4%），而模式之间没有差异（长时间：90.0±5.6%）（短时间：89.8±4.2%）；此外，还发现了任务*模式的相互作用（ES：强）。在进攻长时间间歇 SSG 中，爱德华兹 TL （56.6+2.4 AU）略高于防守短时间间歇 SSG（52.4+4.4 AU）。C 在 SSG 后增加（ES：强）。在进攻短时间间歇 SSG 后 T 降低（ES：中），在防守长时间间歇 SSG 后 T 增加（ES：中）。
战术任务和训练模式影响篮球 SSG 的外部和内部需求。类固醇激素对 SSG 有反应。
