World Health Organization statement on exercise:
According to the World Health Organization, the most benefit from physical activity is achieved with at least 2.5 hours of aerobic exercise of moderate intensity per week and by performing resistance exercises for muscle strengthening. Increased intensity, frequency and duration of exercise is associated with increased added health benefits. Regular exercise is recommended for not only all healthy individuals, but also those suffering from obesity, diabetes, hypertension, atherosclerotic cardiovascular disease, and cancer. (13)
Resistance training in those with health conditions or in chronically ill patients:
Exercise testing:
Exercise cardiac stress testing should be conducted in individuals who have 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 (patient’s whose heart valve does not open fully), those with heart rhythm disorders, and those with pacemakers is also necessary.
