摘要

背景:本研究旨在探讨16名高训练大学生篮球运动员在20场正式比赛中的幸福感、恢复状态、比赛负荷和比赛表现之间的关系。了解这些因素如何相互作用对于优化竞技篮球的性能和工作量管理至关重要。方法:主成分分析(PCA)确定了影响表现的六个关键成分:PC1(负载)占总方差的50%,PC2(幸福感)占11%,PC3(跳跃)占8%,PC4(高强度跳跃)占6%,而PC5(恢复)和PC6(每分钟PlayerLoad)各占2%。应用广义线性混合效应模型来评估这些成分与关键绩效指标(包括绩效指数评级(PIR)和球员总贡献(PTC))之间的关联。结果:比赛负荷与PIR呈负相关(β=-1.22, 95% CI=-2.33至-0.12)。结论:高强度的体育活动,特别是跳跃,对提高篮球成绩至关重要,而过度的比赛负荷会对结果产生负面影响。幸福和恢复的有限影响表明,它们的影响可能在较长时期或在不同情况下更为明显。未来的研究应该集中在优化游戏负载和高强度动作之间的平衡,以提高性能。

Integrating subjective assessments and wearable-derived metrics: decoding in-game load-performance relationships in collegiate basketball players.

Background: This study aimed to investigate the relationships between well-being, recovery state, game loads, and game performance across 20 official games involving 16 highly trained collegiate basketball players. Understanding how these factors interact is essential for optimizing performance and workload management in competitive basketball.

Methods: Principal component analysis (PCA) identified six key components contributing to performance: PC1 (loads) accounted for 50% of the total variance, PC2 (well-being) explained 11%, PC3 (jump) captured 8%, PC4 (high-intensity jump) explained 6%, while PC5 (recovery) and PC6 (PlayerLoad per minute) each explained 2%. Generalized linear mixed-effects models were applied to assess the associations between these components and key performance indicators, including Performance Index Rating (PIR) and Player Total Contribution (PTC).

Results: Game loads showed a negative association with PIR (β=-1.22, 95% CI=-2.33 to -0.12, P<0.05). In contrast, high-intensity jumps were positively associated with both PIR (β=1.08, 95% CI=0.39 to 1.77, P<0.01) and PTC (β=0.99, 95% CI=0.34 to 1.64, P<0.01), explaining 43.86% of the variance in PIR and 40.17% in PTC. The effects of well-being and recovery were limited.

Conclusions: High-intensity physical activities, particularly jumps, are crucial to enhancing basketball performance, while excessive game loads can negatively impact outcomes. The limited influence of well-being and recovery suggests that their effects may be more evident over longer periods or under different contexts. Future research should focus on optimizing the balance between game loads and high-intensity actions to improve performance.
