下肢肌力不對稱對運動表現與運動傷害的影響──以文獻回顧的方式進行探討

The Impact of Lower Limb Muscle Strength Asymmetry on Athletic Performance and Sports Injuries: A Literature Review

目的：以文獻回顧的方式，統整並說明下肢肌力不對稱的定義、測量方式以及突顯可能對運動員造成的影響。方法：以下肢肌力不對稱為關鍵詞在Web of science, Pubme, Google scholars, PEDro, Cochrane library及中國知網等資料庫中進行搜尋，整理下肢肌力不對稱有關之重要資訊及其測量方式與對運動表現及造成運動傷害機轉之國內、外文獻，使讀者瞭解下肢不對稱可能導致的嚴重性。結果：男性相較於女性有更高的機率有下肢不對稱的問題，同時若下肢肌力不對稱性達到10-15%以上，則非接觸的運動傷害機率會上升。結論：下肢肌力不對稱性過高可能導致運動傷害的風險提高，運動員應定期檢測是否有下肢不對稱的問題，藉此評估並降低可能發生的機率。

Purpose: Through a literature review approach, this study aims to consolidate and elucidate the definitions, measurement methods, and highlighted potential impacts of lower limb muscle strength asymmetry on athletes. Methods: A systematic search was conducted using the keywords ''lower limb muscle strength asymmetry'' in databases including Web of Science, PubMed, Google Scholar, PEDro, Cochrane Library, and CNKI. Relevant literature concerning important information related to lower limb muscle strength asymmetry, its measurement methods, and its effects on athletic performance and injury mechanisms were compiled from both domestic and foreign sources, with the intention of informing readers about the severity of lower limb asymmetry. Results: There is a higher likelihood of lower limb asymmetry in males compared to females. Additionally, if lower limb muscle strength asymmetry exceeds 10-15%, the probability of non-contact sports injuries increases. Conclusions: Elevated levels of lower limb muscle strength asymmetry may increase the risk of sports injuries. Athletes should undergo regular assessments to detect lower limb asymmetry, allowing for evaluation and mitigation of potential risks.
