This study aimed to determine the risk of anterior cruciate ligament (ACL) injury in female college students according to sleep quality and use this information to prevent injury.
Twenty-six female university students were recruited for the present study. Participants underwent assessments for sleep quality, landing error scoring system (LESS), and electromyographic (EMG) activity for imbalances by comparing the muscle activity of the left and right rectus femoris (RF-to-RF) and biceps femoris (BF-to-BF) muscles.
The good sleep group exhibited significantly lower LESS scores (good sleep group: 5.13 ± 1.46, poor sleep group: 7.09 ± 1.38, p = 0.004). Additionally, the EMG activity of the RF-to-RF (good sleep group: 20.82 ± 20.29, poor sleep group: 41.74 ± 24.76, p = 0.019) and the EMG activity of the BF-to-BF (good sleep group: 27.09 ± 25.40, poor sleep group: 109.92 ± 93.43, p = 0.001) were significantly lower in the good sleep group. In all participants, a positive correlation was found between the PSQI total score and EMG activity of BF-to-BF (r = 0.446, p < 0.05), as well as the LESS score and EMG activity of BF-to-BF (r = 0.601, p < 0.01).
This study demonstrated the relationship between sleep quality and ACL injury risk factors among female university students. We strongly recommend that these students improve their sleep quality to reduce and prevent ACL risk.
本研究旨在根据睡眠质量确定女大学生前交叉韧带（ACL）损伤的风险，并利用这些信息预防损伤。
本研究招募了26名女大学生。参与者接受了睡眠质量评估、落地误差评分系统（LESS）以及通过比较左右股直肌（RF-to-RF）和股二头肌（BF-to-BF）肌肉的肌电活动来评估失衡的肌电图（EMG）活动。
良好睡眠组的LESS评分显著更低（良好睡眠组：5.13±1.46，睡眠不佳组：7.09±1.38，p = 0.004）。此外，良好睡眠组的RF-to-RF肌电活动（良好睡眠组：20.82±20.29，睡眠不佳组：41.74±24.76，p = 0.019）和BF-to-BF肌电活动（良好睡眠组：27.09±25.40，睡眠不佳组：109.92±93.43，p = 0.001）显著更低。在所有参与者中，PSQI总分与BF-to-BF肌电活动之间存在正相关（r = 0.446，p < 0.05），以及LESS评分与BF-to-BF肌电活动之间存在正相关（r = 0.601，p < 0.01）。
本研究证明了女大学生睡眠质量与ACL损伤风险因素之间存在关联。我们强烈建议这些学生改善睡眠质量以降低和预防ACL损伤风险。
