Abstract

Background: The presence of inter-limb asymmetry in the human body has traditionally been perceived to be detrimental for athletic performance. However, a systematic review addressing and comprehensively assessing the association of asymmetry between the lower limbs and middle- and long-distance running performance-related metrics is currently lacking.

Objective: The main purpose of this systematic review was to examine the relationship between lower inter-limb asymmetry and determinants of running performance in healthy middle- and long-distance runners. The secondary objective was to identify possible avenues for further research in this area.

Methods: PubMed, Web of Science and SPORTDiscus were systematically searched for studies investigating the relationship between lower inter-limb asymmetry and (determinants of) running performance in healthy and injury-free middle- and long-distance runners. The quality of studies eligible for inclusion was assessed using the Downs and Black Quality Index Tool.

Results: Out of 4817 articles screened, 8 studies were included in this review which assessed the association between functional, morphological, kinematic and kinetic asymmetry and running performance-related metrics. The quality score of the included research varied between 5/10 and 9/10. Our results revealed mixed findings, showing both significant negative (n = 16) and positive (n = 1) associations as well as no significant associations (n = 30) between inter-limb asymmetry and running performance-related metrics.

Conclusions: A high heterogeneity across study methods and outcomes was apparent, making it difficult to draw a straightforward conclusion. Our results indicate that the majority of metrics of functional, morphological, kinematic and kinetic inter-limb asymmetry are negatively or not associated with running performance (and/or its determinants). Thus, a more extensive high-quality body of research using standardised asymmetry magnitude metrics is essential to determine whether, and to what extent asymmetry between the lower limbs could affect middle- and long-distance running performance. Future studies should establish potential trade-off values to help practitioners develop evidence-based training programs.

Key points: In the majority of the metrics, the magnitude of lower inter-limb asymmetry was negatively or not associated with middle- and long-distance running performance. Coaches, athletes and researchers should be attentive of the task, time- and metric-specificity as well as the inter- and intra- individual variability of magnitude outcomes, when assessing inter-limb asymmetries.

健康人群肢体间不对称与中长跑成绩决定因素之间的关系:系统回顾
背景:人体肢体间的不对称历来被认为不利于运动表现。然而,目前还缺乏针对下肢间不对称与中长跑成绩相关指标之间关系的全面评估的系统性综述:本系统综述的主要目的是研究健康中长跑运动员下肢间不对称与跑步成绩决定因素之间的关系。次要目的是确定该领域进一步研究的可能途径:方法:系统检索了 PubMed、Web of Science 和 SPORTDiscus,以查找调查健康和无伤病的中长跑运动员下肢间不对称与跑步成绩(决定因素)之间关系的研究。采用唐斯和布莱克质量指数工具对符合纳入条件的研究进行了质量评估:结果:在筛选出的 4817 篇文章中,有 8 项研究被纳入本综述,这些研究评估了功能、形态、运动学和动力学不对称与跑步成绩相关指标之间的关联。所纳入研究的质量得分介于 5/10 和 9/10 之间。我们的结果喜忧参半,在肢体间不对称与跑步成绩相关指标之间,既有显著的负相关(n = 16)和正相关(n = 1),也有不显著的相关(n = 30):结论:不同研究方法和结果之间的异质性很明显,因此很难得出直接的结论。我们的研究结果表明,大多数肢体间功能、形态、运动学和动力学不对称指标与跑步成绩(和/或其决定因素)呈负相关或不相关。因此,要确定下肢间的不对称是否以及在多大程度上会影响中长跑成绩,就必须使用标准化的不对称幅度指标进行更广泛、更高质量的研究。未来的研究应确定潜在的权衡值,以帮助从业人员制定循证训练计划:在大多数指标中,下肢间不对称的程度与中长跑成绩呈负相关或不相关。教练员、运动员和研究人员在评估肢间不对称时应注意任务、时间和指标的特异性,以及幅度结果的个体间和个体内差异性。
