It reduces all-cause mortality 1,2 and the risk of many diseases, including cardiovascular disease, 3 some types of cancer, 4 diabetes mellitus, hypertension, obesity, and depression. The recommended intensity, frequency, and duration of the physical activity varies, depending on whether the target is health promotion, primary or secondary cardiovascular prevention, rehabilitation, or weight control, among others. On the basis of new scientific evidence, the ACSM and the American Heart Association AHA have recently adapted their recommendations to combine the duration, frequency and intensity of activity and now recommend that "all healthy adults aged 18 to 65 years need moderate-intensity aerobic physical activity for a minimum of 30 minutes on 5 days each week or vigorous-intensity aerobic activity for a minimum of 20 minutes on 3 days each week. Leisure-time physical activity LTPA refers to exercise, sports or recreation that is not related to regular work, housework, or transport activities. However, information on adherence to these guidelines in Mediterranean populations of Southern Europe, such as Madrid, is lacking.
