To verify the association of the isometric strength of the shoulder external rotators (ER) and serratus anterior (SA) with the performance of functional tests CKCUEST, SMB-T, and USSP-T in overhead athletes.
Cross-sectional study.
Eighty overhead athletes with no history of surgery in the upper and lower limbs and trunk in the past year, and no painful symptoms in the upper body during the physical assessment were included.
Preseason assessment included isometric strength of shoulder ER and SA, and performance of the CKCUEST, SMB-T, and USSP-T. Multiple linear regression analysis was performed to identify if the isometric strength of the shoulder ER and SA could explain the performance during the tests after controlling for sex.
The isometric strength of SA was associated (p < 0.05) with the SMB-T and USSP-T with 4% of explain. The isometric strength of the SA was not associated (p > 0.05) with the CKCUEST. The isometric strength of the ER was not associated (p > 0.05) with any of the tests.
The isometric strength of the SA predicted the SMB-T and USSP-T performance. Isometric strength of SA and shoulder ER was not associated with CKCUEST results in athletes overhead.
验证肩外旋肌（ER）和前锯肌（SA）等长力量与 overhead 运动员的 CKCUEST、SMB-T 和 USSP-T 等功能测试表现之间的关联。
横断面研究。
80 名 overhead 运动员，过去一年无上下肢和躯干手术史，身体评估时无上半身疼痛症状。
赛季前评估包括肩 ER 和 SA 的等长力量以及 CKCUEST、SMB-T 和 USSP-T 的表现。进行多元线性回归分析，以确定在控制性别后，肩 ER 和 SA 的等长力量是否可以解释测试中的表现。
SA 的等长力量与 SMB-T 和 USSP-T 相关（p<0.05），解释率为 4%。SA 的等长力量与 CKCUEST 不相关（p>0.05）。ER 的等长力量与任何测试均不相关（p>0.05）。
SA 的等长力量预测了 SMB-T 和 USSP-T 的表现。在 overhead 运动员中，SA 和肩 ER 的等长力量与 CKCUEST 结果无关。
