Physical activity and cardiorespiratory fitness (CRF) (a measure of habitual aerobic physical activity) are related to a lower risk of cancer and cardiovascular diseases (CVDs). [ 1 Laukkanen J.A.

The effective delivery of a comprehensive programme is essential to ensure recovery after a CVD event. [ [4] Scherrenberg M. Zeymer U. Schneider S. Van der Velde A.E. Wilhelm M.

Evidence-based CR should be a multidisciplinary intervention, with control of cardiovascular risk factors, vocational support, psychosocial management, and the prescription of endurance, interval and strength exercise.
