肌肉毛细血管供应的分析通常依赖于估计毛细血管与纤维的比率或毛细血管密度。这两个指数是规模依赖性的，即它们随纤维大小而变化，我们已经研究了基于单个毛细血管的解剖供应面积的替代方法的使用，其允许基于面积而不是纤维数量计算局部毛细血管与纤维的比率或密度。结果表明，在人体骨骼肌，毛细血管供应主要是根据纤维大小缩放，是相对独立的纤维类型。
Analysis of muscle capillary supply usually relies on estimating either the numerical capillary to fibre ratio or capillary density. Both indices are scale dependent, i.e. they vary with fibre size, We have examined the use of an alternative approach based on the anatomical supply area of individual capillaries, which allows the calculation of a local capillary to fibre ratio or density based on area, rather than number of fibres. The results suggest that, in human skeletal muscle, capillary supply is primarily scaled according to fibre size, and is relatively independent of fibre type.
