This study aimed to evaluate the technical-tactical, perceptual and mental demands of basketball small-sided games (SSGs). Twelve male semi-professional players participated in four half-court 3vs3 SSGs characterized by different tactical tasks (offensive; defensive) and training regimes (long-intermittent; short-intermittent). The SSGs were video-recorded to perform notational analysis of technical-tactical parameters. Ratings of perceived exertion (RPE, CR-100 scale), mental effort (ME) and e njoyment were collected after completion of each SSG. Before and after the SSGs, players reported their perceived mental fatigue (MF); for this indicator, the difference between post- and pre-SSG values was calculated (ΔMF). Notational analysis evidenced a higher volume of play (ball possessions, ball possessions per minute) [large effect size (ES)], dribbles and shot attempts (moderate ES) in short-intermittent regimes compared to long-intermittent. Two-way (tactical task; training regime) repeated-measures ANOVA showed an interaction effect for RPE (moderate ES). Players reported that playing the offensive task required higher mental effort compared to playing defence (moderate ES), while no differences for mental effort were found between regimes. Enjoyment did not differ between tasks or regimes. No effects were found for ΔMF, while this indicator was significantly correlated with RPE scores (= 0.50, large). This study suggests that, in basketball SSGs, shorter regimes induce higher technical demands, while tactical tasks influence perceived exertion responses and mental effort. Furthermore, perceived exertion appears significantly associated with variations of mental fatigue induced by training drills.
本研究旨在评估篮球小范围比赛（SSG）的技战术、感知和心理需求。12名男性半职业球员参与了4场半场3对3的小范围比赛，这些比赛具有不同的战术任务（进攻；防守）和训练模式（长间歇；短间歇）。对小范围比赛进行视频录制，以便对技战术参数进行记录分析。在每场小范围比赛结束后，收集主观用力程度（RPE，CR - 100量表）、心理努力程度（ME）和愉悦感评分。在小范围比赛前后，球员报告他们感知到的心理疲劳（MF）；对于该指标，计算小范围比赛后与比赛前数值的差异（ΔMF）。记录分析表明，与长间歇模式相比，短间歇模式下的比赛量（控球次数、每分钟控球次数）[效应量（ES）大]、运球次数和投篮尝试次数（中等ES）更多。双向（战术任务；训练模式）重复测量方差分析显示，主观用力程度存在交互效应（中等ES）。球员报告称，与防守相比，执行进攻任务需要更高的心理努力（中等ES），而不同模式之间在心理努力方面未发现差异。任务或模式之间的愉悦感没有差异。未发现ΔMF有影响，而该指标与主观用力程度评分显著相关（= 0.50，大）。本研究表明，在篮球小范围比赛中，较短的模式会带来更高的技术要求，而战术任务会影响主观用力程度反应和心理努力。此外，主观用力程度似乎与训练练习引起的心理疲劳变化显著相关。
