中文摘要：

采用文献资料调研、专家访谈、测试和实验等方法对李妮娜膝关节前十字韧带重建术后15～32周进行了个性化康复性体能训练，根据她的实际情况和参赛要求制定了两个大阶段的康复性体能训练目标，实施了有针对性和实效性的康复性体能训练任务和训练方案。研究结果表明，通过术后15～32周康复性体能训练，使李妮娜完全康复并重返训练场，并在赛季中取得了优异成绩。术后33周，膝关节左、右侧最大屈伸力矩都有明显增长，伤侧膝关节屈伸最大力矩增长显著，屈伸最大力矩比值更趋于合理；术后37周，15项体能测试指标中11项达到伤前最好成绩，1项超过伤前最好成绩，3项接近伤前最好成绩，双腿对称度达到了98％，专项运动能力和身体机能达到了专项技术训练和比赛的要求。
