Physiological Cross Sectional Area, combined with muscle parameters

specimen #4_r



 


Description:

Blank entries in the columns indicate that data were not available.

PCSA = Physiological Cross-Sectional Area. PCSA was estimated in three different ways; dependent on mass, dependent on volume and pennation angle and ignoring the pennation angle. When pennation angle was smaller than 15°, PCSA(1) and PCSA(2) have been estimated with a = 15°. (see the Introduction for an explanation of the methods)

r = muscle density = 1060 kg/m3 (Cutts & Seedhom, 1993).
