Abstract：
UNASSIGNED: This study aims to explore the variations in external and internal loads on a quarter-by-quarter basis among professional Chinese basketball players. It emphasizes the crucial impact of these variations on optimizing athletic performance and match strategies.
UNASSIGNED: An observational longitudinal study design was employed, involving sixteen male players from the National Basketball League during the 2024 season in China. Data collection was facilitated through the use of Catapult S7 devices for measuring external loads and session ratings of perceived exertion (sRPE) for assessing internal loads. Linear mixed-effects models were utilized for the statistical analysis to identify differences in workload intensities across game quarters based on player positions. The Pearson correlation coefficient was used to examine the relationship between external and internal load throughout the game.
UNASSIGNED: The analysis uncovered significant positional differences in workload intensities across game quarters. Guards were found to have a higher PlayerLoad™ (PL) per minute in the first quarter, while centers demonstrated an increase in high-intensity accelerations and jumps in the fourth quarter. Furthermore, a significant moderate correlation between sRPE and PL was observed across all game quarters, indicating a link between physical exertion and athletes\' perceptions of effort.
UNASSIGNED: The study offers new insights into the dynamic physical demands faced by basketball players and the importance of using both objective and subjective measures for a comprehensive assessment of athlete performance and wellbeing. The findings underscore the interconnectedness of physical exertion and athlete perception, providing a foundation for future research and practical applications in the field of basketball science.

摘要：
■本研究旨在探讨中国职业篮球运动员在季度基础上的外部和内部负荷的变化。它强调了这些变化对优化运动表现和比赛策略的关键影响。
■采用了观察性纵向研究设计，在2024赛季期间，来自中国国家篮球联赛的16名男性球员参与其中。通过使用弹射器S7设备测量外部载荷和评估内部载荷的会话等级（sRPE），可以促进数据收集。线性混合效应模型用于统计分析，以根据玩家位置确定游戏季度的工作量强度差异。皮尔逊相关系数用于检查整个游戏中外部和内部负荷之间的关系。
■分析揭示了游戏区工作量强度的显着位置差异。在第一季度，发现卫兵每分钟的PlayerLoad™（PL）较高，而中锋在第四季度表现出高强度加速度和跳跃的增加。此外，在所有游戏季度中观察到sRPE和PL之间存在显著的中等相关性，表明体力消耗和运动员对努力的看法之间的联系。
■这项研究为篮球运动员所面临的动态身体需求以及使用客观和主观措施对运动员表现和健康进行全面评估的重要性提供了新的见解。这些发现强调了体力消耗和运动员感知之间的相互联系，为篮球科学领域的未来研究和实际应用奠定了基础。
