This study aimed to assess the effect of playing different pick-and-roll (PnR) defensive tactical options during small-sided games (SSGs) on external and internal loads in female basketball players.
Twelve female basketball players (age 28 [2] y; stature 175 [6] cm; body mass 65 [7] kg; playing experience 18 [4] y) belonging to a team competing in the Lithuanian second division were recruited for this study. Across 3 experimental sessions and in a randomized order, players performed 3 SSGs sharing the same features but using 3 defensive strategies on the middle PnR action: Switch, Trap, and Drop. External load was measured using PlayerLoad (PL); the number of accelerations, decelerations, and changes of direction, classified based on their intensities as low (<2.5 m·s-2), medium (2.5-3.5 m·s-2), and high (>3.5 m·s-2); and jumps categorized as low (<40 cm) and high (≥40 cm). Internal load was measured via rating of perceived exertion (RPE).
Higher PL values in SSGs including Trap defense were found compared with Drop (P < .001, ES = 0.69, moderate) and Switch (P = .001, ES = 0.60, moderate). Additionally, a higher number of accelerations was registered in Trap defense compared with Drop defense (P = .027, ES = 0.99, moderate). Trap defense also led to higher RPE compared with Switch (P = .003, ES = 1.49, large) and Drop (P = .004, ES = 1.42, large) defense.
Different defensive strategies on the middle PnR can influence the external and internal loads during SSGs, and female basketball coaches should consider the high demand of the Trap defense when designing SSGs.
本研究旨在评估在小场比赛（SSG）中采用不同的挡拆（PnR）防守战术选项对女性篮球运动员的外部和内部负荷的影响。
本研究招募了一支参加立陶宛乙级联赛的女子篮球队的 12 名女性篮球运动员（年龄 28[2]岁；身高 175[6]厘米；体重 65[7]公斤；运动经验 18[4]年）。在 3 个实验中，球员以随机顺序进行 3 个 SSG，这些 SSG 具有相同的特征，但在中间的 PnR 动作中使用 3 种防守策略：Switch（切换）、Trap（夹击）和 Drop（放掉）。使用 PlayerLoad（PL）测量外部负荷；根据其强度将加速度、减速和变向次数分类为低（<2.5 m·s-2）、中（2.5-3.5 m·s-2）和高（>3.5 m·s-2）；跳跃分为低（<40 厘米）和高（≥40 厘米）。内部负荷通过感知用力评分（RPE）进行测量。
与 Drop（P<0.001，ES=0.69，中度）和 Switch（P=0.001，ES=0.60，中度）相比，Trap 防守的 SSG 中的 PL 值更高。此外，与 Drop 防守相比，Trap 防守中记录到更多的加速（P=0.027，ES=0.99，中度）。与 Switch（P=0.003，ES=1.49，大）和 Drop（P=0.004，ES=1.42，大）相比，Trap 防守也导致更高的 RPE。
在中间的 PnR 上使用不同的防守策略会影响 SSG 中的外部和内部负荷，女性篮球教练在设计 SSG 时应考虑到 Trap 防守的高需求。
