A controlled study was carried out in physical training school and non-physical-training school students. The results demonstrated that the SBP and DBP were significantly lower in physical training school students than control students, exercise may shift the entire blood pressure distribution of a population toward lower ranges,and the effects of exercise on DBP may be independent of other variables. Analyses of association between energy expenditure and blood pressure showed that there may be inverse...

A controlled study was carried out in physical training school and non-physical-training school students. The results demonstrated that the SBP and DBP were significantly lower in physical training school students than control students, exercise may shift the entire blood pressure distribution of a population toward lower ranges,and the effects of exercise on DBP may be independent of other variables. Analyses of association between energy expenditure and blood pressure showed that there may be inverse relationship between energy expenditure and blood pressure. These findings suggest that it is possible to prevent hypertension by exercise and that exercise may play an significant role in primary prevention of the cardiovasculardiseases.
