Figure 2Skeletal muscle enzyme activities (assayed at 28°C) in adult zebrafish (Danio rerio) after exposure to cold (18°C, T) for 2 and 4 weeks and after 4 weeks of exercise training (Ex) at 28°C, compared to 28°C controls (C)
Values are presented for A, citrate synthase (CS) B, cytochrome oxidase (COx), C, β-hydroxyacyl-CoA dehydrogenase (HOAD), D, lactate dehydrogenase (LDH) and E, pyruvate kinase (PK) All measurements are from group 1 n= 10, except HOAD from group 2, n= 5. *Significantly different from controls (P < 0.05). U, μmol min−1. Error bars represent s.e.m.
