(a) The basal blood pressure (mmHg) in control (■) and exercising (□) animals. Data are expressed as means S.E.M., –18. (b) The effect of recreational physical exercise on ST segment changes (measured in a lead II standard surface ECG; expressed in mV) following intravenous injection of epinephrine (10.0 μg/kg) and 30 s later phentolamine (15.0 mg/kg). Data are shown as means S.E.M, –18. Statistical significance: as compared with the control group.
