Abstract

Combat sports are very demanding in terms of physical fitness as well as the risk of injury. Elite athletes during daily training due to specific movements can develop significant muscle asymmetry that can affect injury. The aim of this study was to systematically review the existing literature with respect to total average value of hamstrings- to-quadriceps (H/Q) 60°·s-1 and H/Q 180°·s-1 in judo, karate, taekwondo and wrestling. We placed special emphasis on sex-based differences and possible asymmetries between legs in terms of isokinetic performance. This document was developed and reported in accordance with the Guidelines for Preferred Reports for Systematic Reviews and Meta-Analyzes (PRISMA). Web of Science, PubMed and Google Scholar were searched for the relevant studies. Studies were included in the review if they were original and written in English and had to have H/Q ratio measured as an outcome. In total, data from 243 athletes from eleven studies included studies was analysed. The Mean of H/Q 60°·s-1 for all sports were: 58.33% for the right leg and 58.91% for the left leg. Women had higher values: 59.38% vs. 57.42% for the right leg and 61.35% vs. 56.56% for the left leg. The Mean of H/Q 180°·s-1 for all sports were: 71.44% for the right leg and 71.35% for the left leg. Women had higher values: 75.76% vs. 69.04% for the right leg and 73.39% vs. 70.33% for the left leg. All these values, combined for all sports, and divided into subgroups according to gender, show that they are within the recommended values. Combined results for all included studies showed that there was no asymmetry between the left and right leg. According to the results of the balance of the mentioned agonists and antagonists, which are crucial for knee joint stabilization during dynamic muscle contractions, we can conclude that athletes in combat sports do not represent a risk group.
搏击运动中等速腿筋-股四头肌峰值扭矩比:系统回顾和荟萃分析
格斗运动对体能要求很高,也有受伤的风险。优秀运动员在日常训练中,由于特定的动作会产生明显的肌肉不对称,从而影响受伤。本研究的目的是系统地回顾现有文献中关于柔道、空手道、跆拳道和摔跤中腘绳肌-股四头肌(H/Q) 60°·s-1和H/Q 180°·s-1的总平均值。我们特别强调了基于性别的差异和腿之间在等速运动表现方面可能存在的不对称。本文件是根据系统评价和荟萃分析首选报告指南(PRISMA)编写和报告的。检索了Web of Science、PubMed和Google Scholar等相关研究。如果研究是原创的,用英语写的,并且必须测量H/Q比率作为结果,则纳入综述。总共分析了来自11项研究的243名运动员的数据。各运动H/Q 60°·s-1的平均值分别为:右腿58.33%、左腿58.91%。女性的数值更高:右腿59.38%比57.42%,左腿61.35%比56.56%。各运动H/Q 180°·s-1平均值分别为:右腿71.44%、左腿71.35%。女性的数值更高:右腿75.76% vs. 69.04%,左腿73.39% vs. 70.33%。所有这些数值,结合所有运动项目,并根据性别划分子组,表明它们在推荐值范围内。所有纳入研究的综合结果表明,左腿和右腿之间没有不对称。根据上述激动剂和拮抗剂的平衡结果,我们可以得出结论,搏击运动中的运动员并不代表一个危险群体,这对动态肌肉收缩期间的膝关节稳定至关重要。
