目的：本研究确定阻力训练与跑步训练相结合是否能提高大腰肌的横截面积（CSA），即髋屈肌，从而提高长跑运动员的表现。方法：以8名训练有素的男性长跑运动员为研究对象。5000米赛跑的个人最好成绩是15分10秒（0分20秒）。每名受试者每周进行两次阻力训练和跑步训练，持续12周。作者使用了3种阻力训练方案来训练髋屈肌。训练强度最多为10次重复。前4周训练3组× 10次，后8周训练4组× 10次。作者使用磁共振成像测量了大腰肌的CSA，并在长跑运动员训练前（前）和训练后（后）使用等速跑步测试测量了长跑运动员的表现。结果：组合训练显著（P< 0.01,d= 0.34）提高了大腰肌CSA（训练前：16.2 [1.5]cm2，训练后：16.7 [1.4]cm2），显著（P< 0.01,d= 1.41）提高了等速跑测试持续时间（训练前：500 [108]s，训练后：715 [186]s）。此外，多元回归分析显示，恒速运动前后持续时间的变化与大腰肌CSA的变化显著相关。结论：大腰肌阻力训练配合跑步训练与长跑运动员成绩的提高有一定的相关性。
Purpose:The study determined whether the increase in the cross-sectional area (CSA) of psoas major, which is known as a hip-flexion muscle, by resistance training combined with running training improves the performance of long-distance runners.Methods:Subjects were 8 well-trained male long-distance runners. The personal best time in a 5000-m race was 15:10.0 (0:20.5) (mean [SD]). Each subject performed resistance training twice per week with running training for 12 weeks. The authors used 3 resistance training regimens that would train the hip flexor muscles. Training intensity was a maximum of 10 repetitions. The training amount was 3 sets × 10 times during the first 4 weeks followed by 4 sets × 10 times during the last 8 weeks. The authors measured the CSA of psoas major using magnetic resonance imaging and the performance of long-distance runners using a constant velocity running test before (pre) and after (post) the training term.Results:The combination training significantly (P< .01,d= 0.34) increased the CSA of psoas major (pre: 16.2 [1.5] cm2, post: 16.7 [1.4] cm2) and significantly (P< .01,d= 1.41) improved the duration of the constant velocity running test (pre: 500 [108] s, post: 715 [186] s). Moreover, multiple regression analysis showed that the pre to post change in the duration of the constant velocity exercise was significantly correlated with the change in CSA of the psoas major.Conclusion:The authors suggest that resistance training of psoas major with running training is correlated with an improvement in the performance of long-distance runners.
