To compare kinematic and ground reaction force (GRF) patterns between the dominant and non-dominant limbs in males and females conducting the closed kinetic chain upper extremity stability test (CKCUEST).
Descriptive.
Biomechanics laboratory.
Sixteen male and sixteen female healthy and physically active young adults.
Hand contact and flight times, peak and average vertical (vGRF) and medial-lateral (mlGRF) ground reaction forces, medial-lateral (ML) distance and ML velocity per repetition, three-dimensional (3D) distance and 3D velocity per repetition, and average number of touches per trial during the CKCUEST.
Only peak and average mlGRF were statistically different between limbs. Males and females were statistically different across every measured variable. ML and 3D velocities were the only variables strongly correlated to the number of touches achieved.
Both sexes were symmetrical between limbs in all but mlGRF; however, there were distinct differences in both kinematics and GRF patterns between sexes that may be attributed to differences in the testing position between males and females.
比较男性和女性在进行闭链上肢稳定性测试（CKCUEST）时，优势和非优势肢体的运动学和地面反力（GRF）模式。
描述性研究。
生物力学实验室。
16 名男性和 16 名女性健康且有运动能力的年轻成年人。
手接触和飞行时间、垂直（vGRF）和内外侧（mlGRF）地面反力峰值和平均值、重复的内外侧（ML）距离和 ML 速度、三维（3D）距离和重复的 3D 速度，以及在 CKCUEST 中每次试验的平均触球次数。
仅在肢体间的峰值和平均 mlGRF 存在统计学差异。男性和女性在所有测量变量上均存在统计学差异。ML 和 3D 速度是与触球次数密切相关的唯一变量。
除了 mlGRF 外，两性在所有肢体间都是对称的；然而，两性之间的运动学和 GRF 模式存在明显差异，这可能归因于男女测试姿势的差异。
