HAGBERG, J.M., G.E. MOORE, and R.E. FERRELL. Specific genetic markers of endurance performance and V̇o2max. Exerc. Sport Sci. Rev., Vol. 29, No. 1, pp 15–19, 2001. Recent advances have revolutionized genetic studies of quantitative traits. Mitochondrial DNA and creatine kinase variations may influence V̇o2max. Other data strongly suggest that angiotensin-converting enzyme genotype affects V̇o2max and endurance performance capacity, but the mechanisms are unclear. A recent genome-wide scan study also has provided candidate loci requiring further study.
