BACKGROUND
Lower extremity (LE) injuries are common across many sports. Both core strength (including hip strength) deficits and poor postural stability have been linked to lower extremity (LE) injury. The relationship between these two characteristics is unknown.
PURPOSE
To explore the relationships between hip strength, static postural stability, and dynamic postural stability.
STUDY DESIGN
Descriptive Cross-Sectional Study.
METHODS
162 Division I student-athletes (111 males and 51 females) participated in this study. Isometric hip strength was measured using a hand-held dynamometer and both single-leg static (eyes open EO and eyes closed EC) and dynamic postural stability were assessed with a force plate. Pairwise correlations were calculated to examine the relationship between the hip strength variables and the postural stability scores for all subjects and separately for males and females.
RESULTS
There were no significant correlations between hip strength and dynamic postural stability for any of the pairwise correlations. Significant, albeit minimal, correlations between EO and EC static postural stability and each of the hip strength variables for all subjects and male subjects (correlation coefficients ranged from -0.19 to -0.34). However, there were only two significant correlations between hip strength and EC static postural stability (hip internal/external rotation) and one for hip strength and EO postural stability (hip internal rotation) found for female subjects (correlation coefficients ranged from -0.28 to -0.31).
CONCLUSION
There was no relationship between isometric hip strength and dynamic postural stability; whereas, there were some relationships between the strength measures and static postural stability. These significant, but minimal correlations were observed in more of the comparisons within the male cohort potentially demonstrating a sex difference.

背景
下肢损伤在许多运动项目中都很常见。核心力量（包括髋部力量）不足和姿势稳定性差都与下肢损伤有关。这两个特征之间的关系尚不清楚。
目的
探讨髋部力量、静态姿势稳定性和动态姿势稳定性之间的关系。
研究设计
描述性横断面研究。
方法
162名一级院校学生运动员（111名男性和51名女性）参与了本研究。使用手持测力计测量等长髋部力量，并用测力板评估单腿静态（睁眼EO和闭眼EC）和动态姿势稳定性。计算所有受试者以及男性和女性受试者的髋部力量变量与姿势稳定性得分之间的成对相关性，以检验它们之间的关系。
结果
在任何成对相关性中，髋部力量与动态姿势稳定性之间均无显著相关性。所有受试者和男性受试者的睁眼和闭眼静态姿势稳定性与每个髋部力量变量之间存在显著相关性，尽管相关性较小（相关系数范围为-0.19至-0.34）。然而，女性受试者中仅发现髋部力量与闭眼静态姿势稳定性（髋部内/外旋）之间有两个显著相关性，以及髋部力量与睁眼姿势稳定性（髋部内旋）之间有一个显著相关性（相关系数范围为-0.28至-0.31）。
结论
等长髋部力量与动态姿势稳定性之间没有关系；而力量测量与静态姿势稳定性之间存在一些关系。在男性队列中的更多比较中观察到了这些显著但较小的相关性，这可能表明存在性别差异。
