Effective utilization of genetic information for athletes and coaches: focus on ACTN3R577X polymorphism

Naoki Kikuchi and Koichi Nakazato. Effective utilization of genetic information for athletes and coaches: focus on ACTN3R577X polymorphism. JENB., Vol. 19, No. 3, pp.157-164, 2015 [Abstract] Training variants (type, intensity, and duration of exercise) can be selected according to individual aims and fitness assessment. Recently, various methods of resistance and endurance training have been used for muscle hypertrophy and VO2max improvement. Although several genetic variants are associated with elite athletic performance and muscle phenotypes, genetic background has not been used as variant for physical training. ACTN3R577X is a well-studied genetic polymorphism. It is the only genotype associated with elite athletic performance in multiple cohorts. This association is strongly supported by mechanistic data from an Actn3-knockout mouse model. In this review, possible guidelines are discussed for effective utilization of ACTN3R577X polymorphism for physical training. [Key words] Genotype, physical training, trainability, muscle phenotype, endurance performance
