May associate endurance training with blunted renin-angiotensin activation during exercise; hypothesis-generating and should not yet alter practice.
Does endurance training alter plasma levels of renin, angiotensin II, and 6-ketoprostaglandin F1 alpha during graded exercise in healthy males?
Endurance athletes exhibit lower plasma renin activity and a blunted rise in angiotensin II during exercise compared to nonathletes, without differences in blood pressure or prostacyclin metabolites.
Fagard et al. (1985) studied this question.
