Static muscle exercise tests consisting of one-third maximum voluntary contraction of the forearm for 5 min was carried out in a group of older (mean age 46.8 yr) and younger men (mean age 25.3 yr). The mean hemodynamic changes in the two groups were quite comparable with increases in heart rate (31.3 and 38.4 beats/min), systolic pressure (74.3 and 63.2 mmHg), and diastolic pressure (58.1 and 47.3 mmHg) in older and younger groups, respectively. There was a prompt postexercise increase in mean total plasma catecholamine level in older males with a rapid decline over the next 15 min; the increase …
