Abstract excerpt
1. Salbutamol, a beta 2-agonist, increased the weight of the canine latissimus dorsi muscle. It also increased fusion frequency, and decreased time-to-peak tension, half-relaxation time, and total contraction time. These changes in twitch times and fusion frequency were associated with changes in the levels of proteins expressed in slow- and fast-twitch fibres. Salbutamol decreased the levels of the slow-twitch...
