: The aim of this study was to analyze the relationship between physical preparation, training sessions (TS) and friendly matches' (FM) demands, and playing status during European Championship (EC). : Twelve under-16 (U-16) basketball players performed physical (jumping, agility, aerobic fitness, and lower limb asymmetry index [ASI]) tests prior to attending the national team training camp. External training load was assessed using the WIMU PRO System put in place during TS (n = 19) and FM (n = 3), integrating the national team preparation. Perceptual response (RPE), muscle soreness (DOMS), and game-related statistics were also collected. Playing status during the U-16 EC (starters vs nonstarters) were taken into consideration to analyze the between-subjects differences across all variables. A stepwise discriminant analysis was computed to identify the construct that best differentiated the players' playing status (starters vs nonstarters) during the EC. : The starters were characterized by lower movement demands in both TS (ES: -0.02 to -1.26) and FM (ES: -0.03 to -1.94), however, outscored nonstarters in most FM-related statistics (ES: 0.10 to 3.62), with exception to blocks and rebounds. The number of high-intensity decelerations during FM (p ≤ .05), but also training DOMS, number of steals, efficiency, minutes during FM, and countermovement jump (CMJ) (p ≤ .01) substantially discriminated the playing status over the course of the EC. : Game-related statistics obtained in FM seem to be a determinant aspect that increases the probability to be the starter during the EC.
: 本研究旨在分析身体准备、训练课（TS）和友谊赛（FM）的需求以及在欧洲锦标赛（EC）期间的比赛状态之间的关系。12 名 16 岁以下（U-16）篮球运动员在参加国家队训练营前进行了体能（跳跃、敏捷、有氧健身和下肢不对称指数[ASI]）测试。使用 WIMU PRO 系统在 TS（n = 19）和 FM（n = 3）期间评估外部训练负荷，整合了国家队的准备工作。还收集了感知反应（RPE）、肌肉酸痛（DOMS）和与比赛相关的统计数据。考虑到 U-16 EC 期间的比赛状态（首发球员与非首发球员），分析了所有变量的受试者间差异。进行逐步判别分析以确定最佳区分 EC 期间球员比赛状态（首发球员与非首发球员）的构建。首发球员在 TS（ES：-0.02 至-1.26）和 FM（ES：-0.03 至-1.94）中的运动需求较低，但在大多数 FM 相关统计数据（ES：0.10 至 3.62）中得分高于非首发球员，除了盖帽和篮板。在 FM 期间的高强度减速次数（p ≤.05），以及训练 DOMS、抢断次数、效率、FM 期间的分钟数和下蹲跳（CMJ）（p ≤.01）在整个 EC 过程中都能很好地区分比赛状态。FM 中获得的比赛相关统计数据似乎是一个决定性的方面，它增加了在 EC 中成为首发球员的可能性。
