From: Specific fibre composition and metabolism of the rectus abdominis muscle of bovine Charolais cattle
Principal Component Analysis on muscular properties in RA, TB and LT muscles. A: RA muscles of 153 Charolais heifers. B : TB muscles of 19 Charolais steers. C: LT muscles of 153 Charolais heifers. PCA 1, PCA 2 : proportion of variance explained by axes 1 and 2. The PCA was established only on the muscular properties studied in the three muscles; MyHC I, IIa, IIx : proportions of myosin heavy chain isoforms I, IIa and IIx; LDH: Lactate Dehydrogenase activity; ICDH: Isocitrate Dehydrogenase activity; COX: Cytochrome-c-Oxidase activity; Area : mean fibre cross-sectional area.
