The Hip Stability Isometric Test (HipSIT) is a practical clinical assessment of posterolateral hip muscle performance. There is no information regarding the validity of the HipSIT in participants exposed to high-intensity training, such as CrossFit®.
The purpose of this study was to investigate the Hip Stability Isometric Test (HipSIT) concurrent validity with the isokinetic assessment in CrossFit® participants. A secondary purpose was to characterize posterolateral hip muscular performance with HipSIT according to sex and lower limb dominance in athletes who participate in CrossFit®.
Cross-sectional.
One-hundred and eleven CrossFit® participants were evaluated. The posterolateral hip muscles were evaluated using the HipSIT with a hand-held dynamometer. The hip extensors and abductors' peak torque and maximum work were assessed with the Biodex System® 4 Pro isokinetic dynamometer at 60º/s. Concurrent validity between measurements was assessed with the Spearman correlation coefficient and Bland-Altman analyses. The comparison of results between sexes and between limbs was also performed.
Spearman analyses indicated a significant positive correlation with medium effect size between HipSIT and isokinetic variables ( = 0.36 to 0.49). Bland-Altman analyses showed that most measures were within the 95% limits of agreement. The HipSIT was greater in males than females (p < 0.001) and greater in the dominant than non-dominant limb (p = 0.03).
The findings support using HipSIT in the clinical assessment of CrossFit® participants. Clinicians can use the data as reference values for athletes who participate in CrossFit® and should consider the difference between sexes and lower limbs.
髋关节稳定性等长测试（HipSIT）是一种对髋关节后外侧肌肉功能进行的实际临床评估。目前尚无关于高强度训练参与者（如参与CrossFit®训练者）中HipSIT有效性的相关信息。
本研究旨在调查CrossFit®参与者中髋关节稳定性等长测试（HipSIT）与等速测试的同时效度。第二个目的是根据参与CrossFit®训练的运动员的性别和下肢优势，用HipSIT来描述髋关节后外侧肌肉功能。
横断面研究。
对111名CrossFit®参与者进行评估。使用手持测力计通过HipSIT评估髋关节后外侧肌肉。使用Biodex System® 4 Pro等速测力计在60°/s时评估髋伸肌和外展肌的峰值扭矩和最大功。测量之间的同时效度通过Spearman相关系数和Bland-Altman分析进行评估。还进行了性别和肢体之间结果的比较。
Spearman分析表明，HipSIT与等速变量之间存在显著的正相关，效应量中等（r = 0.36至0.49）。Bland-Altman分析表明，大多数测量值在95%一致性界限内。男性的HipSIT值高于女性（p < 0.001），优势肢体的HipSIT值高于非优势肢体（p = 0.03）。
研究结果支持在CrossFit®参与者的临床评估中使用HipSIT。临床医生可以将这些数据用作参与CrossFit®训练的运动员的参考值，并应考虑性别和下肢之间的差异。
