摘　　要："拮抗肌离心峰力矩/原动肌向心峰力矩"常用于评价过肩运动项目运动员肩关节做旋转运动过程中拮抗肌离心力量与原动肌向心力量的均衡性,是近年来在国外运动医学文献中出现频度较高的一个专业术语。对肩关节做旋转等速测试时拮抗肌离心峰力矩与原动肌向心峰力矩比值的等速测试方法及其在评定肩关节旋转肌群肌力平衡中的应用进行综述。研究发现,拮抗肌离心峰力矩与原动肌向心峰力矩的比值是对肩关节进行旋转(外旋或内旋)等速测试过程中定量地诊断拮抗肌离心肌力与原动肌向心肌力的均衡性,比外旋肌群与内旋肌群向心峰力矩的比率能更客观地反映肩关节在做旋转运动过程中原动肌与拮抗肌的不同生理收缩状态以及不同收缩形式下肌力的均衡性;虽然国外研究者普遍认为"拮抗肌离心峰力矩/原动肌向心峰力矩"应大于1,但关于该比值的理想区间还没有取得一致的观点。Eccentric antagonist/concentric agonist strength ratios is widely used in evaluating balance between eccentric strength of antagonist and concentric strength of agonist during shoulder joint movement in the overhead athlete, and frequently found in the sport medical lit-eratures recently abroad. By the method of literature review, this paper reviewed the method of isokinetic testing, interpretation, significance, computation and application of the eccentric an- tagonist/concentric agonist strength ratios. The study found that the ratios between eccentric antagonist peak torque and concentric agonist peak torque of isokinetic shoulder rotation （ex-ternal or internal rotation） test was used for diagnosing the equilibrium between eccentric an-tagonist muscle strength and concentric agonist muscle strength, reflecting the different physio-logical contraction form between antagonist and agonist objectively than the ratios between ex-ternal rotators and internal rotation muscles concentric peak torque. Although foreign research-ers generally believed that eccentric antagonist/concentric agonist strength ratios should be greater than 1 when made isokinetic shoulder rotation test, the ideal interval on the ratio has not yet reached agreement.
