许多青少年足球运动员经历下腰痛(LBP)。然而，还没有关于青少年足球运动员经历下腰痛的踢球运动的研究报告。本研究旨在明确青少年足球运动员在有无下脚点的情况下的踢球动作。我们招募了42名青少年足球运动员，根据有无LBP将他们分为两组(LBP组，n=22)和不存在LBP组(NBP组，n=20)。我们使用三维运动分析系统实时测量踢球运动。我们在每个解剖地标上放置了65个球形标记，并计算了腰椎角度、全身质心(COM)和支撑足的位移。我们使用未配对的t检验来比较两组之间的数据。与NBP组相比，LBP组的COM出现侧移，这增加了踢球运动的持续时间。LBP的存在影响了支撑脚的后位，并限制了球员的腰椎横向弯曲。在踢腿运动中，COM的侧移和腰椎较大的旋转可能会对腰椎造成压力。因此，教练员和教练员应注意足球运动员踢球时的腰椎旋转和COM移位。这对于预防青少年足球运动员患上腰痛很重要。
Many adolescent soccer players experience low back pain (LBP). However, there are no reports studying the kick motion of adolescent soccer players experiencing LBP. This study aimed to clarify the kick motion of adolescent soccer players in the presence and absence of LBP. We recruited 42 adolescent soccer players and divided them into two groups according to the presence of LBP (LBP group, n = 22) and absence of LBP (NBP group, n = 20). We measured real-time kick motion using a three-dimensional motion analysis system. We placed 65 spherical markers on each anatomical landmark and calculated the angle of the lumbar spine, center of mass (COM) of the whole body, and displacement of the support foot. We used an unpaired t-test to compare the data between the groups. Compared with the NBP group, the LBP group showed a lateral shift in COM, which increased the duration of kick motion. The presence of LBP affected the posterior positioning of the support foot and restricted the player's lumbar spine from bending laterally. A lateral shift in COM and larger rotation of the lumbar spine could stress the lumbar spine during kick motion. Therefore, coaches and athletic trainers should pay attention to soccer players' lumbar spine rotation and the COM shift during kick motion. This would be important for preventing LBP in adolescent soccer players.
