The purpose of this study was to identify the external demands during official under-18 basketball matches that included four quarters (Q1, Q2, Q3, Q4) and/or overtime (OT) periods. Variables included: 1) distance covered and distance covered within four intensity zones (standing-walking S-W, jogging JOG, running RUN, and high-speed running HSR); 2) explosive efforts per minute (EEs); 3) PlayerLoad (PL); 4) the number of jumps per minute; 5) the number of accelerations above 2 m·s2 (ACCs); and 6) the number of decelerations above -2 m·s2 per minute (DECs). The values for total distance, JOG, RUN, HSR, PL, ACC, and DEC were significantly smaller during periods Q2, Q3, Q4, and OT compared to Q1. In addition, the number of EEs during Q1 was significantly greater than during Q3, Q4, and OT. When comparing OT periods to Q2, there were significantly smaller values for total distance, RUN, and PL. Similarly, when comparing OT periods to Q3, significantly smaller values were found for PL. Furthermore, when comparing OT periods to Q4, significantly smaller values were achieved for total distance and PL. These findings indicate that players experienced a decrease in external physical demands as the match progressed to an OT period. This decrease may be indicative of player fatigue and/or strategic changes that should be considered by practitioners in the preparation and management of players for overall team success in junior basketball competitions.
本研究的目的是确定18岁以下官方篮球比赛期间的外部需求，该比赛包括四个小节（Q1、Q2、Q3、Q4）和/或加时赛（OT）时段。变量包括：1）在四个强度区域（站立-行走S-W、慢跑JOG、跑步RUN和高速奔跑HSR）内覆盖的距离和总距离；2）每分钟的爆发性动作次数（EEs）；3）运动员负荷（PL）；4）每分钟的跳跃次数；5）加速度超过2 m·s2的次数（ACCs）；以及6）每分钟减速度超过-2 m·s2的次数（DECs）。与Q1相比，在Q2、Q3、Q4和OT时段，总距离、JOG、RUN、HSR、PL、ACC和DEC的值显著更小。此外，Q1期间的EEs次数显著多于Q3、Q4和OT期间。将OT时段与Q2进行比较时，总距离、RUN和PL的值显著更小。同样，将OT时段与Q3进行比较时，PL的值显著更小。此外，将OT时段与Q4进行比较时，总距离和PL的值显著更小。这些发现表明，随着比赛进入OT时段，运动员所经历的外部身体需求减少。这种减少可能表明运动员疲劳和/或策略变化，在青少年篮球比赛中，从业者在为球队整体成功准备和管理运动员时应考虑这些因素。
