title: [Prevention by physical activity. The relevance of physical fitness].
abstract: Regular physical activity is now recognized as an important and very effective step to prevent many diseases, especially those of the cardiovascular system. Many studies within the last 20 years have also shown that exercise capacity or fitness is an important prognostic factor in healthy subjects and patients with cardiovascular diseases for both mortality and morbidity. Physical fitness, which is mainly determined by regular physical activity or training, can be analyzed by maximal exercise testing using the treadmill or cycle ergometry. In addition, fitness is also based on genetic factors. There are some methodological criticisms concerning self-reported questionnaires of physical activity, MET (metabolic equivalent) calculations and exhaustion during maximal voluntary stress testing. However, the results of both approaches are valid and reliable for daily use. Accordingly, every physician regardless of his or her discipline should encourage all patients at every visit to follow a healthy lifestyle, including regular exercise and physical activity. This also applies to older patients, who especially benefit from exercise and physical activity.
