Groin pain is one of the common problems in multidirectional sports. It seems that abnormal muscular activity and improper movement strategy led to prolongation and high rate of this injury. Therefore, the aim of this study was to Comparing the Average amplitude of Electromyography (AEMG), co-contraction ratio (CCR) of selected thigh and thoracic muscle during turning in individuals with chronic groin pain and healthy individuals.
Surface electromyography was collected from the internal oblique/transversus abdominis (IO/TrA), multifidus (MF), adductor Longus (AL) and gluteus Medius (GM) for AEMG and CCR analyzed in 16-males with LSGP and 16-controls in four motion phases during 11 cycles of gait coupled with turning.
Results revealed that in the AEMG apart from the third phase in the muscle of the IO/ Tr. A muscle and in the second phase in the MF muscle in the trunk and in the third phase in the muscle of the AL and the fourth phase in the GM foot Left There was a significant difference in other phases. There was a significant difference in the CCR, except in the second phase of the trunk and the fourth phase of the left foot in the rest of the phases.
It seems that in athletes with LSGP, have selective muscular activation and CCR have during turning, that may be resulting in compensatory strategies and movement control defects, which may be a useful tool to predict LSGP occurrence in players with a history of groin pain.
腹股沟疼痛是多向运动中的常见问题之一。似乎异常的肌肉活动和不当的运动策略导致了这种损伤的延长和高发生率。因此，本研究的目的是比较慢性腹股沟疼痛患者和健康个体在转身时大腿和胸部肌肉的平均肌电图幅度（AEMG）和协同收缩比（CCR）。
对 16 名 LSGP 男性和 16 名对照组男性在 11 个步态周期结合转身的 4 个运动阶段中，从内部斜肌/横腹肌（IO/TrA）、多裂肌（MF）、长收肌（AL）和臀中肌（GM）采集表面肌电图，用于 AEMG 和 CCR 分析。
结果表明，在 AEMG 中，除了躯干中 IO/Tr. A 肌肉的第三阶段和 MF 肌肉的第二阶段以及左足的 AL 肌肉的第三阶段和 GM 肌肉的第四阶段外，其他阶段均存在显著差异。在 CCR 中除了躯干的第二阶段和左足的第四阶段外，其他阶段也存在显著差异。
似乎患有 LSGP 的运动员在转身时存在选择性肌肉激活和 CCR，这可能导致代偿策略和运动控制缺陷，这可能是预测有腹股沟疼痛史的运动员 LSGP 发生的有用工具。
