Abstract

Background: Physical preparation in basketball is essential but often limited by training time and prior focus on tactical and technical skills. While postural stability is known to assist injury prevention and performance, its specific impact on game-related performance remains unclear. With the development of motion analysis systems, the numerical values of external and internal loads measured during matches have become measurable. This study aimed to examine the relationship between postural stability and game-related performance and introduce a method for visualizing key competencies.

Method: Twenty-three U16 female basketball players (age = 15.22 ± 0.82 years, mass = 66.3 ± 8.85 kg, high = 174.0 ± 8.2 cm) participated from the Hungarian first league. Postural stability was assessed via plank test and one minute dynamic standing balance tests, while game-related performance was monitored through match-derived internal and external load values measured by WIMU PRO™ System, alongside statistical data derived from the official box scores. After the postural stability measurements, we monitored an official basketball match, which was conducted according to official International Basketball Association (FIBA) rules. For clear and comprehensive presentation, we combined the game-related performance indicators using Principal Component Analysis (PCA).

Results: A moderate correlation (0.5 < r < 0.8, p < 0.05) was found between the game-related performance and postural stability variables. However, plank test indicators showed no significant correlations with game-related performance variables, except for bad throws (r = 0.56, p = 0.037), the postural error (PE), a variable reflecting compensatory movement during fatigue in the plank test, correlated with balance indicators (r = 0.63, p = 0.014). Mediolateral balance control correlated with explosive game-related performace metrics, including maximum acceleration (r = -0.65, p = 0.01), deceleration (r = 0.56, p = 0.035), and steals (r = -0.52, p = 0.05). PCA proved effective in creating game competency scores, enabling a graphical representation of game-related performance.

Conclusion: Findings suggest that trunk endurance alone was not directly related to game-related performance, while dynamic balance metrics showed moderate correlations. The PE values provide deeper insights into the balance-trunk stability relation. The dynamic balance test could support player monitoring, and the PCA based method facilitates player profiling.

整合青年精英篮球运动员的躯干耐力,动态稳定性和比赛表现分析。
背景:篮球运动中的身体准备是必不可少的,但往往受到训练时间和先前对战术和技术技能的关注的限制。虽然已知姿势稳定性有助于预防伤害和表现,但其对比赛相关表现的具体影响尚不清楚。随着运动分析系统的发展,在比赛中测量的外载荷和内载荷的数值已经可以测量。本研究旨在探讨姿势稳定性与游戏相关表现之间的关系,并介绍一种可视化关键能力的方法。方法:来自匈牙利第一联赛的23名U16女子篮球运动员(年龄= 15.22±0.82岁,体重= 66.3±8.85 kg,身高= 174.0±8.2 cm)。姿势稳定性通过平板测试和一分钟动态站立平衡测试来评估,而游戏相关的表现则通过由WIMU PRO™系统测量的源自比赛的内部和外部负荷值来监测,以及来自官方盒子分数的统计数据。在姿势稳定性测量之后,我们监控了一场官方篮球比赛,比赛是根据国际篮球协会(FIBA)的官方规则进行的。为了清晰而全面的呈现,我们使用主成分分析(PCA)结合了游戏相关的性能指标。结论:研究结果表明,躯干耐力本身与游戏相关表现没有直接关系,而动态平衡指标具有中等相关性。PE值可以更深入地了解balance-trunk的稳定性关系。动态平衡测试可以支持玩家监控,基于PCA的方法有助于玩家分析。
