我们进行了一项前瞻性研究，以确定在前交叉韧带重建后的前16周内引入低负荷肌肉训练并适度限制血流量的效果。44例受试者，平均年龄29岁（18-52岁），随机分为限制血流训练组（R组，n = 22）和不限制血流训练组（n组，n = 22）。两组都遵循相同的训练计划。术前和术后16周对膝关节伸肌和屈肌扭矩的评估显示，R组肌肉力量较n组显著增加。术后16周，R组膝关节伸肌横截面积术前/术后16周的比值较n组有统计学意义的增大。股外侧肌1、2型纤维短径R组（n = 8）大于n组（n = 8），但差异不显著。这些发现表明，在适度限制血流的情况下进行低负荷阻力肌肉训练是前交叉韧带重建后早期肌肉训练的有效运动。
We performed a prospective study to determine the effects of introducing low-load muscular training with moderate restriction of blood flow during the first 16 weeks after reconstruction of the anterior cruciate ligament. 44 subjects (average age 29 (18-52) years) were randomized into a group that trained restriction of blood flow (group R, n = 22) and a group that trained without restriction (group N, n = 22). Both groups followed the same training schedule. Evaluations of knee extensor and flexor torques before surgery and 16 weeks after it showed a significant increase in muscular strength in group R as compared to group N. The preoperative/16-week postoperative ratio of the cross-sectional area of the knee extensor muscles showed a statistically significant enlargement in group R as compared to group N. 16 weeks after surgery, the short diameters of type 1 and type 2 fibers of M. vastus lateralis tended to be larger in group R (n = 8) than in group N (n = 8), although the differences were not significant. These findings show that low-load resistance muscular training during moderate restriction of blood flow is an effective exercise for early muscular training after reconstruction of the anterior cruciate ligament.
