Clenbuterol acutely increases energy expenditure and fat metabolism
Next to the effects of clenbuterol on blood pressure, heart rate, energy expenditure, and plasma substrates after 14 days of treatment, we also investigated the acute effects of clenbuterol administration. Thus, on day 1 of each treatment arm, blood pressure, heart rate, energy metabolism, and plasma substrates were determined over the course of 4 hours upon acute clenbuterol (20 µg) versus placebo administration. Systolic- and diastolic blood pressure remained unaffected during the 4 hours following acute clenbuterol administration (20 µg) as compared to placebo (treatment effect:
