Groin injuries are common in soccer and often cause time-loss from training. While groin injuries have been linked to full effort kicking, the role of inside passing is unclear. Therefore, the purpose of this study was to investigate hip joint kinematics and muscle force, stress and contraction velocity for adductor longus and gracilis during inside passing. 3D kinematics of ten soccer players (23.4 yrs; 77.5 kg; 1.81 m) were captured with a motion capture system inside a Footbonaut. Muscle force and contraction velocity were determined with AnyBody Modelling System. Gracilis muscle forces were 9% lower compared to adductor longus (p = 0.005), but muscle stress was 183% higher in gracilis (p = 0.005). Contraction velocity reveals eccentric contraction of gracilis in the last quarter of the swing phase. Considering the combination of eccentric contraction, high muscle stress and the repetitive nature of inside passing, gracilis accumulates high loads in matches and training. These results indicate that the high incidence of groin injuries in soccer could be linked to isolated pass training. Practitioners need to be aware of the risk and refrain from sudden increases in the amount of pass training. This gives the musculoskeletal system time to adapt and might avoid career threatening injuries.  相似文献

优秀游泳运动员中肩部疼痛是常见现象,但其发病机理仍不完全清楚。冈上肌肌腱炎可能是导致肩部疼痛的主要病因,训练的强度和持续时间均能使肌腱增厚,产生撞击综合症,引发肌腱炎,导致疼痛,其发生机制可能与重复性应力刺激激活了蛋白激酶表达,使得细胞凋亡增加,导致肌腱炎和最终的退行性病变。  相似文献

Abstract

Cartilage oligomeric matrix protein is a structural protein of the extracellular matrix, while thrombospondin-2 is a matricellular protein involved in cell–matrix interactions. Recent studies have shown that genetic variation is a significant risk factor for Achilles tendinopathy, and the genes encoding cartilage oligomeric matrix protein (COMP) and thrombospondin-2 (THBS2) were identified as good candidate genes for association with Achilles tendinopathy. This study aimed to test the association of sequence variants within these candidate genes with the risk of Achilles tendinopathy in participants from South Africa (SA) and Australia (AUS). Three-hundred and forty (133 SA; 207 AUS) control participants with no history of Achilles tendinopathy and 178 (94 SA; 84 AUS) participants clinically diagnosed with Achilles tendinopathy were genotyped for five single nucleotide polymorphisms within the COMP and THBS2 genes in this case-control study. There was no difference in genotype distributions between control and tendinopathy groups for either the THBS2 variants rs9505888, rs6422747 and rs9283850, or the COMP variants rs730079 and rs28494505 in the SA and AUS populations. As the selection of COMP and THBS2 as candidate genes was hypothesis driven, based on biological function, the possibility that other variants within these genes are associated with Achilles tendinopathy cannot be excluded.  相似文献

目的:评估体外冲击波联合肌内效贴治疗跟腱腱病的临床疗效。方法:选取20名研究对象,随机分成单纯冲击波治疗(ESWT)组和体外冲击波联合肌内效贴共同治疗(ESWT+KT)组,每组各10人。分别于治疗前、治疗后1个月、治疗后3个月对所有患者采用VISA-A跟腱腱病评分表进行评分。在治疗后3个月时采用6点Likert评分表对患者主观满意度进行评价,在治疗前和治疗后3个月用高频彩超对比跟腱纤维形态变化。结果:(1)VISA-A评分:ESWT、ESWT+KT两组治疗后VISA-A评分与其治疗前比较存在显著的统计学差异(P<0.01);ESWT+KT组治疗后各时间点与治疗前的VISA-A评分差值与ESWT组相比存在统计学差异(P<0.05)。(2) 6点Likert评分:ESWT+KT组的患者满意率为100%,高于ESWT组(80%)。(3)高频彩超:ESWT、ESWT+KT两组治疗后的跟腱肿胀比治疗前都有缓解,且ESWT+KT组的肿胀改善程度优于ESWT组。结论:体外冲击波治疗跟腱腱病和联合肌内效贴共同治疗跟腱腱病都能够改善症状,患者满意程度高,且联合治疗组的疗效要优于单独治疗组。  相似文献

目的:采用磁共振(MRI)超短回波时间序列(UTE)评估冈上肌腱的病变程度,探讨UTE序列在游泳运动员冈上肌腱腱病中的诊断价值。方法:纳入2016年3月-2017年2月于复旦大学附属华山医院运动医学科就诊的肩痛游泳运动员共10名(病变组),并招募健康志愿者10名(对照组)。对所有受试者肩关节行MRI常规序列和UTE序列,对冈上肌腱病变进行分级,测量UTE-T2*值后做两组间的比较及病变组内不同分级病例间的比较。结果:所有受检者的常规MRI图像均无明显的肩袖撕裂征象。磁共振常规序列显示对照组中0级4例,1级6例;而病变组中0级3例,1级7例,两组之间结果没有显著差异(P>0.05)。磁共振UTE序列结果显示病变组冈上肌腱整体区域及止点区域T2*值均显著高于对照组(P<0.05);病变组0级病例止点区域T2*值与1级病例之间没有显著差异(P>0.05)。结论:UTE序列能够定量评估冈上肌腱情况,这有助于游泳运动员肩关节疼痛的早期发现与准确诊断。  相似文献
