Groin pain in soccer players arises from various causes, most commonly kicking, and as such can significantly affect performance. A new form of exercise, the cross-motion swing exercise (CMS), may help prevent groin pain but is untested.
To evaluate the effectiveness of the CMS in preventing groin pain in high school soccer players.
Randomized controlled trial; Level of evidence, 1.
This study involved 135 male high school soccer players <18 years from 4 teams competing in a high school soccer league in Japan. Teams were randomly assigned to an intervention group (2 teams; n = 65 players) or a control group (2 teams; n = 70 players). The intervention group performed the CMS in addition to their usual warm-up, emphasizing coordination and kicking movements, while the control group continued their usual warm-up exercise. The intervention period lasted 16 weeks, with compliance monitored weekly. Data were collected through weekly Google form surveys. The primary outcome was the incidence of groin pain at any time during the study period.
The intervention group had a significantly lower incidence of groin pain (9.4%) compared with the control group (23.1%). Cox proportional hazards regression analysis indicated a significantly reduced risk of groin pain in the intervention group (hazard ratio, 0.309; 95% CI, 0.108-0.880; = .028). The number of injuries was 6 in the intervention group and 18 in the control group, and injuries due to the kicking motion were 0 in the intervention group (0%) and 7 in the control group (38.9%).
The CMS significantly reduced the incidence of groin pain in high school soccer players. This suggests that coordination-based exercise, closely mimicking the appropriate sports-specific movement, was effective in reducing injury. The study supports incorporating the CMS into regular training to reduce the incidence of groin pain in male high school soccer players.
This study has been registered as a clinical trial with the Universal Medical Information Network (UMIN) under the registration number UMIN000051311.
足球运动员腹股沟疼痛由多种原因引起，最常见的是踢球，因此会显著影响运动表现。一种新的运动形式，即交叉运动摆动练习（CMS），可能有助于预防腹股沟疼痛，但尚未经过测试。
评估CMS对预防高中足球运动员腹股沟疼痛的有效性。
随机对照试验；证据等级，1级。
本研究纳入了来自日本一个高中足球联赛中4支球队的135名18岁以下的男性高中足球运动员。球队被随机分为干预组（2支球队；n = 65名球员）或对照组（2支球队；n = 70名球员）。干预组除了进行常规热身外，还进行CMS练习，重点是协调和踢球动作，而对照组继续进行常规热身运动。干预期持续16周，每周监测依从性。数据通过每周的谷歌表单调查收集。主要结局是研究期间任何时间腹股沟疼痛的发生率。
干预组腹股沟疼痛的发生率（9.4%）显著低于对照组（23.1%）。Cox比例风险回归分析表明干预组腹股沟疼痛风险显著降低（风险比，0.309；95%CI，0.108 - 0.880；P = 0.028）。干预组受伤人数为6人，对照组为18人，干预组因踢球动作导致的受伤人数为0（0%），对照组为7人（38.9%）。
CMS显著降低了高中足球运动员腹股沟疼痛的发生率。这表明基于协调的练习，紧密模仿适当的特定运动动作，在减少损伤方面是有效的。该研究支持将CMS纳入常规训练，以降低男性高中足球运动员腹股沟疼痛的发生率。
本研究已在通用医学信息网络（UMIN）注册为临床试验，注册号为UMIN000051311。
