Consideration of workload intensity and peak demands across different periods of basketball games contributes to understanding the external physical requirements of elite basketball players. Therefore, the aim of this study was to investigate the average intensity and peak demands encountered by players throughout game quarters. PlayerLoad per minute and PlayerLoad at three different time samples (30 s, 1 min, and 3 min) were used as workload metrics. A total of 14 professional elite male basketball players were monitored during 30 official games to investigate this. A linear mixed model and Cohen's d were employed to identify significant differences and quantify the effect sizes among game quarters. The results showed a significant, moderate effect in PlayerLoad per minute between Q1 vs. Q4, and a small effect between Q2 and Q3 vs. Q4. Furthermore, a small to moderate decline was observed in external peak values for PlayerLoad across game quarters. Specifically,, a significant decrease was found for the 3 min time window between Q1 and other quarters. The findings from the present study suggest that professional basketball players tend to experience fatigue or reduced physical output as the game progresses.
考虑到不同篮球比赛时期的工作量强度和高峰需求，有助于理解精英篮球运动员的外部身体需求。因此，本研究的目的是调查球员在整个比赛季度中遇到的平均强度和高峰需求。每分钟的球员负荷（PlayerLoad per minute）和三个不同时间样本（30 秒、1 分钟和 3 分钟）的球员负荷（PlayerLoad at three different time samples）被用作工作量指标。共有 14 名专业精英男性篮球运动员在 30 场正式比赛中接受了监测，以调查这一点。线性混合模型和科恩的 d 用于确定比赛季度之间的显著差异和量化效应大小。结果表明，在 PlayerLoad per minute 方面，Q1 与 Q4 之间存在显著的中等效应，Q2 和 Q3 与 Q4 之间存在较小的效应。此外，PlayerLoad 在比赛季度之间的外部峰值呈小到中等程度的下降。具体来说，在 3 分钟的时间窗口中，Q1 与其他季度之间存在显著下降。本研究的结果表明，随着比赛的进行，职业篮球运动员往往会感到疲劳或体力输出减少。
