背景:不同运动项目由于其运动方式的不同对身体所施加的机械负荷不同,对骨密度的影响也存在差异.目的:观察武术功力(单掌断砖)和网球两种不同运动方式腕骨受力部位结构的CT图像差异.方法:选择参加第四届全国武术功力大赛的男性运动员8名,主要靠掌腕部(右手)的高冲击力来击断砖块;专业男性网球运动员7名.对15名受试者腕骨进行螺旋CT扫描,并对其二维图像进行过滤、筛减、放大、增强、分割等处理,然后测量豌豆骨和三角骨的灰度和面积.结果与结论:武术运动员豌豆骨3个断面冠状面、横断面和矢状面的灰度均大于网球运动员(P<0.05),面积均小于网球运动员(P<0.05);武术运动员三角骨三个断面的灰度与网球运动员相比差异无显著性意义,而面积均小于网球运动员(P<0.01).证实功力运动员和网球运动员的腕骨结构存在差异,功力运动者部分腕骨的骨密度高于网球运动员,而面积则减小.

BACKGROUND:Different exercises exert varying mechanical load on body, which have diversity effects on bone mineral density. OBJECTIVE: To study the structure differences of the forced carpal bones in the two sports wushu gongli and tennis by use of a spiral CT. METHODS: Eight male wushu athletes and 7 tennis athletes were selected. The carpal bones of the wushu and tennis athletes were scanned by the spiral CT. And the two-dimensional images were filtered, screening reduced, enlarged, enhanced, and splited, then the gray and area of pisiform and triquetrum were measured. RESULTS AND CONCLUSION: The gray scale of coronal, horizontal and sagittal sections of the pisiform in wushu athletes were greater than that of tennis athletes (P < 0.05), with smaller areas (P < 0.05). There was no significant gray scale difference of three sections of the triquetrum between two groups, while the area in wushu athletes was less than that in tennis athletes (P < 0.01). The experiment showed that there were some structure differences of the carpal bones between gongli and tennis sports. The bone mineral density of some parts of the carpal in gongli was greater than that in tennis, but the area was reduced in gongli.
