Fig. 1. The alteration of the staining intensities of dihydropyridine (DHP; A,B)
and ryanodine (Ry; C) receptors in white (A) and red (B,C) muscle sections of
salmon. Sections were incubated in 20 nmol l-1 high affinity
(-)-enantiomer of dihydropyridine labelled with orange fluorophore and in 0.5
µmol l-1 high affinity (-)-enantiomer of ryanodine labelled with
green fluorophore. Exercise protocol: three different swimming velocities, 1,
1.5 and 2 BL s-1, and three different training periods, 2,
4 and 6 weeks. Difference between control and trained group significant at
*P<0.05,
P<0.01 or
P<0.001. CL, control level.
