Prolonged treatment with the β2-adrenoceptor agonist clenbuterol (1–2 mg · kg body mass−1 · day −1) is known to induce the hypertrophy of fast-contracting fibers and the conversion of slow- to fast-contracting fibers. We investigated the effects of administering a lower dose of clenbuterol (250 μg · kg body mass−1 · day−1) on skeletal muscle myosin heavy chain (MyHC) protein isoform content and adenine nucleotide (ATP, ADP, and AMP) concentrations. Male Wistar rats were administered clenbuterol ( n = 8) or saline ( n = 6) subcutaneously for 8 wk, after which the extensor digitorum longus (EDL) and soleus muscles were removed. We demonstrated an increase of type IIa MyHC protein content in the soleus from ∼0.5% in controls to ∼18% after clenbuterol treatment ( P < 0.05), which was accompanied by an increase in the total adenine nucleotide pool (TAN; ∼19%, P < 0.05) and energy charge [E-C = (ATP + 0.5 ADP)/(ATP + ADP + AMP); ∼4%; P < 0.05]. In the EDL, a reduction in the content of the less prevalent type I MyHC protein from ∼3% in controls to 0% after clenbuterol treatment ( P < 0.05) occurred without any alterations in TAN and E-C. These findings demonstrate that the phenotypic changes previously observed in slow muscle after clenbuterol administration at 1–2 mg · kg body mass−1 · day−1 are also observed at a substantially lower dose and are paralleled by concomitant changes in cellular energy metabolism.
