Abstract

Angiotensin-converting enzyme (ACE) is a component of the circulating renin–angiotensin system, which influences circulatory homeostasis through the degradation of vasodilator kinins and the generation of vasopressor angiotensin II. Various phenotypic characteristics such as diseases and human performances could be associated with genetic polymorphisms within the ACE gene. To date, one of the most well-studied genetic polymorphisms that has been shown to be associated with athletic performance is that of the ACE gene. Previous studies investigating the influences of polymorphisms and various phenotypic characteristics have produced inconsistent findings due to inter-ethnic variations in the distribution of the different ACE alleles. For example, some studies showed that the I allele was associated with fatigue resistance in skeletal muscle and endurance performance while the D allele had been associated with power or sprint performance. Nevertheless, controversy still exists regarding the above conclusion as related studies reported that the I allele was associated with a better power or sprint performance rather than with athletic endurance abilities. This article discusses the inter-ethnic variations of the distribution of the different ACE alleles in several ethnic groups such as in European, African, American, and Asian populations. Additionally, the influences of the ACE ID polymorphism on human physical fitness performances in European and other populations are discussed.
