Coronary heart disease and physical activity - a fresh look
AbstractIncidences of fatal coronary heart disease in White South African males increased significantly between 1951 and 1970. In those under 60 years of age, the incidence exceeds that in USA. Prevention lies in the early recognition of raised blood lipids and hypertension, and in stopping smoking. The role of physical inactivity is less certain. The physiological knowledge needed for determining the correct speed of walking and running is proposed.
