Influence of exercise and quiet rest on state anxiety and blood pressure.

A series of investigations was performed in which Ss rested quietly for 40-min and performed aerobic exercise on separate occasions. Blood pressure (BP) and state anxiety were assessed prior to and following the conditions. In the first experiment, 15 normotensive Ss were assessed during the 3-h following the treatments. The results revealed that state anxiety and BP were reduced following both conditions. The exercise-induced BP reductions remained significant for 2 to 3 h (P less than 0.05), whereas the BP reductions returned to baseline within 20-min following cessation of quiet rest. The second experiment involved an evaluation of the effects of exercise and quiet rest on 15 pharmacologically controlled hypertensive Ss. A significant reduction in systolic BP (P less than 0.05) was observed following exercise and quiet rest. State anxiety was reduced following quiet rest and exercise (P less than 0.05). It is concluded that exercise and quiet rest have similar effects on state anxiety, and both conditions are followed by a transitory reduction in blood pressure. These anti-anxiety effects, however, are sustained for a longer period following exercise.
