A new study in middle-aged men has shown that the impact of low physical capacity on risk of death is second only to smoking. Lead author Per Ladenvall of the University of Gothenburg said 'The benefits of being physically active over a lifetime are clear. Low physical capacity is a greater risk for death than high blood pressure or high cholesterol.' The study included 792 men from the 'Study of Men Born in 1913' a representative sample of 50 year old men in Gothenburg recruited in 1963. The study was designed to investigate risk factors for cardiovascular disease and mortality.
