摘要

本研究的目的是比较篮球比赛中各季度的最高外部强度。8名半职业男性球员使用加速度计进行监测。对于所有季度，使用15秒、30秒、1分钟、2分钟、3分钟、4分钟和5分钟的样本持续时间，通过PlayerLoad/分钟(PL·min-1)的移动平均来确定峰值强度。使用线性混合模型和效应大小(ES)来比较每个样本持续时间的季度之间的峰值强度。在第1季度和第4季度之间，所有样本持续时间的峰值PL·min-1都有小幅下降(ES = 0.21-0.49)。在第1季度和第2季度之间，样品持续时间为30秒、1分钟和3分钟时，峰值PL·min-1明显下降(ES = 0.24-0.33)，在第3季度和第4季度之间，样品持续时间为2-5分钟时，峰值PL·min-1明显下降(ES = 0.20-0.24)。在篮球比赛中，随着比赛的进展，峰值强度在每个季度都会下降，这为练习者制定特定比赛的训练和战术策略提供了有用的见解。

Peak External Intensity Decreases across Quarters during Basketball Games

The purpose of this study was to compare peak external intensities across game quarters in basketball. Eight semi-professional male players were monitored using accelerometers. For all quarters, peak intensities were determined via moving averages for PlayerLoad/minute (PL·min-1) using sample durations of 15 s, 30 s, 1 min, 2 min, 3 min, 4 min, and 5 min. Linear mixed models and effect sizes (ES) were used to compare peak intensities between quarters for each sample duration. Small decreases in peak PL·min-1 occurred between Quarters 1 and 4 for all sample durations (ES = 0.21-0.49). Small decreases in peak PL·min-1 were apparent between quarters 1 and 2 for 30-s, 1-min, and 3-min sample durations (ES = 0.24-0.33), and between quarters 3 and 4 for 2-5-min sample durations (ES = 0.20-0.24). Peak intensities decline across quarters with game progression in basketball, providing useful insight for practitioners to develop game-specific training and tactical strategies.
