Starting exercise in healthy adults to help prevent hypertension:
According to the American College of Sports Medicine (ACSM) and the American Heart Association (AHA), older adults need moderate-intensity (between 5-6 on a 10-point scale) aerobic endurance activity for a minimum of 30 min which can be achieved in short 10 minute sessions on five days each week or vigorous-intensity aerobic, (rated a 7-8 on a 10-point scale) activity for a minimum of 20 min on 3 days each week (19,20).
Exercise cardiac stress testing in patients before exercise:
Exercise cardiac stress testing should be conducted in patients with suspected or known coronary artery disease, typical and atypical angina or have had prior heart attack. In healthy people, without symptoms, those with multiple heart risk factors (high cholesterol, high blood pressure, family history, obese, diabetes mellitus) or concurrent chronic diseases or those in a high-risk occupation for example pilots, firefighters, law enforcement officers, and transit operators should undergo exercise stress testing. Stress testing is also recommend for men over age 40 and women over age 50 who have been inactive but plan to start vigorous exercise. Evaluation of exercise capacity in patients with heart disease involving one or more of the valves of the heart, those with heart rhythm disorders, and those with pacemakers is also necessary. (21)
