Recent studies demonstrate the link between reduced hip abductor strength and increased risk for knee injury such as patellofemoral pain syndrome in women athletes. Meta-analytic reports indicate that the efficacy of integrative neuromuscular training (INT) is associated with compliance to the prescribed programming. Thus, the purpose was to investigate the compliance effects of a trunk and hip-focused INT exercises on hip abductor strength in young women athletes. In a controlled laboratory study design, 21 high school women volleyball players (mean age = 15.6 ± 1.4 years, weight = 64.0 ± 7.4 kg, height = 171.5 ± 7.0 cm) completed isokinetic hip abductor strength testing in pre- and postintervention, which consisted of 5 phases of supervised progressive trunk and hip-focused INT exercises twice a week for 10 weeks. The compliance effects were analyzed based on the changed hip abductor strength values between pre- and postintervention and 3 different compliance groups using 1-way analysis of variance and Pearson's correlation coefficients. The participants in the high-compliance group demonstrated significant hip abductor peak torque increases compared with noncompliance group (p = 0.02), but not between moderate-compliance and noncompliance groups (p = 0.27). The moderate correlation coefficient value (r = 0.56) was recorded between the isokinetic hip abductor peak torque changes and the 3 compliance groups. Because of the observed significant effects and moderate linear association, the effectiveness of a trunk and hip-focused INT protocol to improve hip abduction strength seems dependent on compliance. Compliance of trunk and hip-focused INT is an important aspect of increasing hip abductor strength increase in young women athletes.
最近的研究表明，髋关节外展肌力量减弱与女性运动员膝关节损伤（如髌股疼痛综合征）风险增加之间存在关联。荟萃分析报告表明，综合神经肌肉训练（INT）的疗效与对规定方案的依从性有关。因此，本研究旨在探讨以躯干和髋关节为重点的 INT 练习对年轻女性运动员髋关节外展肌力量的依从性影响。在一项对照实验室研究设计中，21 名高中女子排球运动员（平均年龄=15.6±1.4 岁，体重=64.0±7.4kg，身高=171.5±7.0cm）在干预前后完成了等速髋关节外展肌力量测试，干预包括 5 个阶段的监督渐进式以躯干和髋关节为重点的 INT 练习，每周两次，共 10 周。依从性效果根据干预前后髋关节外展肌力量值的变化以及 3 个不同的依从性组进行分析，使用单向方差分析和 Pearson 相关系数。高依从性组与非依从性组相比，髋关节外展肌峰值力矩显著增加（p=0.02），但中度依从性组与非依从性组之间无显著差异（p=0.27）。等速髋关节外展肌峰值力矩变化与 3 个依从性组之间的相关系数值为中度（r=0.56）。由于观察到的显著效果和中度线性关联，以躯干和髋关节为重点的 INT 方案改善髋关节外展力量的有效性似乎取决于依从性。以躯干和髋关节为重点的 INT 的依从性是增加年轻女性运动员髋关节外展肌力量增加的一个重要方面。
