PURPOSE/BACKGROUND: Lower extremity injuries such as Anterior Cruciate Ligament (ACL) tears remain a concern in collegiate female athletes. Core endurance and hip strength reportedly influence ACL and lower extremity injury risk. Good neuromuscular control, as measured by the Star Excursion Balance Test (SEBT) test is associated with decreased lower extremity injuries. The exact relationships between core endurance, hip strength, and balance (SEBT scores), and how they impact one another in the female collegiate athlete remain unclear. Thus, the purpose of this study was to investigate relationships between core endurance, hip strength, and balance in collegiate female athletes.
Forty collegiate female athletes (19.6±1.1yrs, 163.1±7.8cm, 61.3±6.5kgs) performed the SEBT in anterior, posterolateral, and posteromedial directions bilaterally (% leg length), McGill's anterior, posterior, and left and right plank core endurance tests (seconds), and hip abductor, flexor, extensor, and external rotator isometric strength tests bilaterally (N) using handheld dynamometry. Pearson's product moment correlations examined relationships between core endurance, hip strength, and balance. A linear regression analysis examined whether core endurance and hip strength influenced balance (p≤0.05).
Anterior SEBT scores were fairly positively correlated with hip flexor and extensor strength. Posterolateral SEBT scores were fairly positively correlated with hip abductor, extensor, and flexor strength (p=0.02-to-0.004; r=0.26-to-0.45). Fair positive correlations existed between posterior core endurance and hip extensor strength bilaterally (right: p=0.02, r=0.37; left: p=0.003, r=0.47). Core endurance and SEBT scores were not correlated (p>0.05). Core endurance and hip strength did not influence SEBT scores (p=0.47).
Overall, hip strength, but not core endurance was related to SEBT scores in collegiate female athletes. Females with greater hip flexor, extensor, and abductor strength also had better anterior and posterolateral SEBT scores. Having females participate in hip muscle strengthening programs may help improve their SEBT balance scores, as a measure of their neuromuscular control and influence their ACL and lower extremity injury risk.

目的/背景：前交叉韧带（ACL）撕裂等下肢损伤仍是大学女运动员关注的问题。据报道，核心耐力和髋部力量会影响ACL及下肢损伤风险。通过星标偏移平衡测试（SEBT）测量的良好神经肌肉控制与下肢损伤减少相关。核心耐力、髋部力量和平衡（SEBT分数）之间的确切关系，以及它们在大学女运动员中如何相互影响仍不清楚。因此，本研究的目的是调查大学女运动员的核心耐力、髋部力量和平衡之间的关系。
40名大学女运动员（19.6±1.1岁，163.1±7.8厘米，61.3±6.5千克）双侧进行前、后外侧和后内侧方向的SEBT（腿长百分比）、麦吉尔前、后及左右平板支撑核心耐力测试（秒），以及使用手持测力计进行双侧髋外展肌、屈肌、伸肌和外旋肌等长力量测试（牛顿）。皮尔逊积差相关分析核心耐力、髋部力量和平衡之间的关系。线性回归分析核心耐力和髋部力量是否影响平衡（p≤0.05）。
前侧SEBT分数与髋屈肌和伸肌力量呈中等正相关。后外侧SEBT分数与髋外展肌、伸肌和屈肌力量呈中等正相关（p = 0.02至0.004；r = 0.26至0.45）。双侧后核心耐力与髋伸肌力量之间存在中等正相关（右侧：p = 0.02，r = 0.37；左侧：p = 0.003，r = 0.47）。核心耐力和SEBT分数无相关性（p>0.05）。核心耐力和髋部力量不影响SEBT分数（p = 0.47）。
总体而言，在大学女运动员中，髋部力量而非核心耐力与SEBT分数相关。髋屈肌、伸肌和外展肌力量较强的女性，其前侧和后外侧SEBT分数也较好。让女性参加髋部肌肉强化计划可能有助于提高她们的SEBT平衡分数，作为衡量其神经肌肉控制的指标，并影响她们的ACL及下肢损伤风险。
