ObjectivesDetermine if (a) a better trunk stability and endurance are associated with an improved whole‐body dynamic balance, and if (b) the assessment tests can be interchanged within each capability.MethodsSixty‐three physically active young males performed three trunk stability (i.e., the lumbopelvic stability, the unstable sitting and the sudden loading sitting tests), three trunk muscle endurance (i.e., the Biering–Sørensen, the side bridge and the front bridge tests) and four whole‐body dynamic balance (i.e., the tandem and the single‐leg stance, the Y‐Balance, and the single‐leg triple hop tests) tests two times. After assessing the reliability of the variables, a Pearson correlation analysis was performed.ResultsThe correlations between trunk stability and endurance tests with dynamic balance tests were non‐significant except for the unstable sitting test with both the tandem (r = 0.502) and the single‐leg stance (r = 0.522) tests. Moreover, no relationships were observed between the trunk stability and the trunk muscle endurance tests. Interestingly, no relationships were found between most tests within each capability (i.e., trunk stability, trunk endurance, and dynamic balance) except: (i) the front bridge stability test and the back (r = 0.461) and the side (r = 0.499) bridge stability tests; (ii) the two side bridge endurance tests (r = 0.786); (iii) the tandem and the single‐leg stance tests (0.439 ≤ r ≤ 0.463); (iv) the Y‐Balance and the single‐leg triple hop tests (0.446 ≤ r ≤ 0.477).ConclusionBetter trunk function does not seem to be a relevant factor for dynamic balance in young active males. In this population, specific measures are needed as the test interchangeability is questioned.

躯干稳定性和耐力是身体活跃的年轻男性全身动态平衡的决定因素吗？多维度分析

目标确定 (a) 更好的躯干稳定性和耐力是否与改善的全身动态平衡相关，以及 (b) 评估测试是否可以在每种能力内互换。 方法 63 名身体活跃的年轻男性进行了三项躯干稳定性测试（即、腰骨盆稳定性、不稳定坐姿和突然负荷坐姿测试）、三项躯干肌肉耐力（即 Biering-Sørensen、侧桥和前桥测试）和四项全身动态平衡（即串联和前桥测试）。单腿站立、Y 平衡和单腿三跳测试）测试两次。在评估变量的可靠性后，进行皮尔逊相关分析。结果除了串联（串联）测试的不稳定坐姿测试外，躯干稳定性和耐力测试与动态平衡测试之间的相关性不显着。r= 0.502）和单腿站立（r= 0.522) 测试。此外，没有观察到躯干稳定性和躯干肌肉耐力测试之间的关系。有趣的是，大多数测试之间没有发现每种能力（即躯干稳定性、躯干耐力和动态平衡）之间的关系，除了：（i）前桥稳定性测试和后桥稳定性测试（r= 0.461) 和边 (r= 0.499) 桥梁稳定性测试；(ii) 两侧桥梁耐久性测试（r= 0.786); (iii) 串联和单腿站立测试（0.439 ≤r≤ 0.463); (iv) Y 平衡和单腿三跳测试（0.446 ≤r≤ 0.477)。结论对于年轻活跃的男性来说，更好的躯干功能似乎并不是动态平衡的相关因素。在这一人群中，由于测试的可互换性受到质疑，因此需要采取具体措施。
