title: The ACE I/D polymorphism and human physical performance.
abstract: The D allele of the angiotensin-converting enzyme (ACE) I/D polymorphism is associated with elevated levels of serum and tissue ACE, increased production of the vasopressor angiotensin II and a reduction in the half-life of the vasodilator bradykinin. Several cardiac and renal conditions appear to have a worse prognosis in subjects homozygous for the D allele, whereas the I allele has been associated with enhanced endurance performance in elite distance runners, rowers and mountaineers. The nature of the gene-environment interaction between ACE I/D polymorphisms and physical training, an overview of recent findings and a discussion of possible underlying mechanisms is the subject of this review.
