The relationship between dynamic postural control, functional mobility and team handball throwing performance, velocity and accuracy, is largely unknown. The hand reach star excursion balance test (HSEBT) is a full kinetic chain assessment tool of these factors. Specifically, L135 and R135 (extension) reaches elicit joint movement combinations similar to the cocking and acceleration phase, while the L45 and R45 (flexion) reaches elicit joint movement combinations similar to the follow-through. The purpose of this study was to determine if specific HSEBT reach measures correlate with team handball throwing performance. Eleven elite female team handball players (21.7 ± 1.8 years; 71.3 ± 9.6 kg; 1.75 ± 0.07 m) executed selected HSEBT reaches before performing five valid step-up overhead throws (1x1m target) from which throwing velocity (motion capture) and accuracy (mean radial error) were quantified. Significant relationships between HSEBT measures and mean radial error, but not throwing velocity were established. Specifically, extension composite scores (L135+R135) for the dominant (150.7 ± 17.4cm) and non-dominant foot (148.1 ± 17.5 cm) were correlated with mean radial error (p < 0.05). Also, specific reaches on the dominant (L135: 87.4 ± 5.6 cm; R135: 63.4 ± 11.8 cm) and non-dominant (R135: 87.0 ± 6.1 cm) foot were correlated with throwing error (p < 0.05). The lack of significant findings to throwing velocity might be due to a ceiling effect of both L135 and R135 and of throwing velocity. We conclude that while there may be other reasons for handball players to train and test functional mobility and dynamic postural control as measured in the HSEBT, no beneficial effect on throwing performance should be expected in an elite group of handball players.
动态姿势控制、功能性移动能力与团队手球投掷表现、速度和准确性之间的关系在很大程度上尚未可知。手 reach 星偏移平衡测试（HSEBT）是这些因素的完整动力链评估工具。具体来说，L135 和 R135（伸展）的触及引出类似于扣球和加速阶段的关节运动组合，而 L45 和 R45（弯曲）的触及引出类似于跟进阶段的关节运动组合。本研究的目的是确定特定的 HSEBT 触及测量是否与团队手球投掷表现相关。11 名精英女性团队手球运动员（21.7 ± 1.8 岁；71.3 ± 9.6 公斤；1.75 ± 0.07 米）在执行五次有效的单足抬高过头投掷（1x1m 目标）之前执行了选定的 HSEBT 触及，其中投掷速度（运动捕捉）和准确性（平均径向误差）进行了量化。在 HSEBT 测量与平均径向误差之间建立了显著的关系，但与投掷速度无关。具体来说，优势脚（150.7 ± 17.4cm）和非优势脚（148.1 ± 17.5cm）的伸展综合得分（L135+R135）与平均径向误差相关（p<0.05）。此外，优势脚（L135：87.4 ± 5.6cm；R135：63.4 ± 11.8cm）和非优势脚（R135：87.0 ± 6.1cm）的特定触及与投掷误差相关（p<0.05）。与投掷速度无显著关系的原因可能是 L135 和 R135 以及投掷速度的上限效应。我们的结论是，虽然手球运动员可能有其他原因需要训练和测试 HSEBT 中测量的功能性移动能力和动态姿势控制，但在精英手球运动员群体中，不应期望对投掷表现产生有益影响。
