Values are means ± S.E.M. †Significantly different from pectoralis and hindlimb muscles in Weddell seal. *Significantly different from Weddell seal (P<0.05). ā(f), mean fiber cross-sectional area; QA(0), number of capillaries per fiber cross-sectional area; NN(c,f), capillary-to-fiber ratio; NCAF, average number of capillaries around a fiber. Dog data was previously reported in Kanatous et al., 2001.
