传统武术套路训练对大学生武术运动员膝关节软骨影响的T2-mapping功能磁共振成像研究

A T2-mapping fMRI Study of the Effects of Traditional Wushu RoutineTraining on Knee Cartilage in College Wushu Athletes

目的:本研究旨在通过T2-mapping功能磁共振影像学技术对大学生武术运动员膝关节软骨进行定量评估,探究传统武术套路训练对大学生武术运动员膝关节软骨的影响。方法:选取9名年龄介于18~25岁之间的大学生武术运动员作为实验组,同时选取18名普通健康的大学生作为对照组。在相同条件下,对两组分别进行右膝关节的T2-mapping磁共振检查,并将膝关节软骨分为股骨内侧髁、胫骨内侧髁、髌软骨、股骨外侧髁及胫骨外侧髁5个感兴趣区,比较实验组与对照组之间T2值的差异,分析各组膝关节软骨不同感兴趣区T2值的变化。结果:(1)不论性别,实验组和对照组各个膝关节面软骨感兴趣区的T2值均未见显著性差异(P>0.05);(2)男性对照组、女性对照组以及女性实验组的膝关节各感兴趣区T2值两两之间均无统计学差异(P>0.05);(3)男性实验组膝关节股骨外侧髁与胫骨内侧髁、髌软骨的T2值差异具有统计学意义(P<0.05)。结论:T2-mapping技术可通过无创手段定量评估传统武术套路训练对大学生膝关节软骨的影响。在长期传统武术套路训练后,男性大学生武术运动员的膝关节出现了异质性改变,因此在训练过程中应该注意调整方案,以实现针对性保护。

Objective:The aim of this study was to quantitatively assess the knee cartilage of college wushu athletes by T2-mapping functional magnetic resonance imaging technique,and to investigate the effect of traditional wushu routine training on the knee cartilage of college wushu athletes.Methods:Nine college wushu athletes between the ages of 18 and 25 were selected as the experimental group, while 18 normal healthy college students were selected as the control group. Under the same conditions, T2-mapping magnetic resonance examination of the right knee joint was performed for both groups, and the knee cartilage was divided into five regions of interest: medial femoral condyle, medial tibial condyle, patellar cartilage, lateral femoral condyle and lateral tibial condyle. The differences in T2 values between the experimental group and the control group was compared, and the changes in T2 values of different regions of interest of the knee cartilage of the respective groups was analyzed. Results: (1) Regardless of gender, no significant difference was found in the T2 values of the cartilage regions of interest in the knee joint surfaces between the experimental group and the control group ( P >0.05). (2) There was no statistically significant difference in the T2 values of the knee joints of the male control group, the female control group, and the female experimental group in each of the regions of interest of the knee joint ( P >0.05). (3) There were statistically significant differences in T2 values between the lateral femoral condyle, medial tibial condyle, and patellar cartilage in the male experimental group ( P <0.05). Conclusion: The T2-mapping technique can be used to quantitatively assess the effects of traditional wushu set training on the knee cartilage of college students by non-invasive means. The knee joints of male college wushu athletes showed heterogeneous changes after long-term traditional wushu routine training, so attention should be paid to adjusting the program to achieve targeted protection during training.
