The effect of antihypertensive medications on exercise performance: a review

This review describes the effects of antihypertensive drugs on the performance of aerobic exercise. All available antihypertensive drugs lower blood pressure both at rest and decrease the rate of increase during exercise. However, they differ in their effects on exercise performance. The ideal antihypertensive agent should not have significant depressant effects on the myocardium, should not promote arrhythmias, should preserve the distribution of blood flow to exercising muscle, and should not interfere with substrate utilization. Diuretics, one of the most commonly prescribed class of antihypertensives, have few deleterious effects on exercise performance but have adverse metabolic effects; beta blockers have many adverse effects on exercise performance. Agents which have the least potential for adverse effects on exercise performance and metabolic effects are the converting enzyme inhibitors, calcium channel blockers, and alpha blockers, and central alpha agonists. The literature concerning each of these drugs is reviewed and recommendations are made for prescribing for the hypertensive who wishes to engage in vigorous exercise.
