背景:下腰痛(LBP)是青少年运动员常见的主诉。虽然不同的研究表明,在一般人群中,LBP与躯干肌厚度之间存在关联,很少有文章在青少年运动员身上研究过它。
目的:本研究的目的是比较腹部外侧肌肉的厚度和功能,在有或没有LBP的青少年足球运动员中,腰椎多裂(LM)的横截面积(CSA)。
方法:总共,有和没有LBP的28名青少年足球运动员,英超参加了这项研究。外斜的厚度,通过超声成像(USI)在休息和收缩时测量两侧的内斜肌和腹横肌以及L4水平的LM肌肉的CSA。此外,腿长差异,腿筋的灵活性,主动腰椎前屈,两组均测量躯干伸肌的等距肌耐力。(研究设计/设置:病例对照研究)。
结果:LBP组和非LBP组的平均(SD)年龄分别为14.0(1.1)和14.1(0.9)岁,分别。两组之间参与者的基线特征没有显着差异。结果显示,LBP和非LBP组之间的所有测量变量之间没有显着差异。
结论:获得的数据支持,青少年足球运动员腹部肌肉厚度与腰背痛的CSA和LBP之间没有相关性。这些发现表明,其他因素而不是深躯干肌肉的厚度可能在青少年足球运动员LBP的病因中起着更重要的作用。
BACKGROUND: Low back pain (LBP) is a common complaint amongst adolescent athletes. While different studies have shown association between LBP and trunk muscle thickness in the general population, few articles have studied it in adolescent athletes.
OBJECTIVE: The aim of this study is to compare lateral abdominal muscle thickness and function, and cross sectional area (CSA) of lumbar multifidus (LM) in adolescent soccer players with and without LBP.
METHODS: In total, 28 adolescent soccer players with and without LBP, from the premier league participated in this study. The thickness of external oblique, internal oblique and transversus abdominis and the CSA of the LM muscles at L4 level on both sides were measured at rest and contraction via ultrasound imaging (USI). In addition, leg length discrepancy, hamstring flexibility, active lumbar forward flexion, and isometric muscle endurance of trunk extensors were measured in both groups. (study design/setting:
case control study).
RESULTS: The mean (SD) age in LBP group and non-LBP group were 14.0 (1.1) and 14.1 (0.9) years, respectively. There was no significant difference in baseline characteristics of participants between groups. Findings showed no significant difference between LBP and non-LBP groups comparing all measured variables.
CONCLUSIONS: The data obtained support that there is not a correlation between abdominal muscle thickness and CSA of the lumbar multifidi and LBP in adolescent soccer players. These findings suggest that other factors rather than the thickness of deep trunk muscles may play a more significant role in the etiology of LBP in adolescent soccer players.
