Outline of Final Research Achievements

To date, over 200 genetic polymorphisms in both nuclear DNA and mitochondrial DNA (mtDNA) have been reported to be associated with physical performance and health-related fitness. However, most studies have been reported in European populations. In this study, we aimed to identify genetics polymorphisms that is associated with elite sporting performance, particularly in Asian populations. From genome-wide association studies, we identified several genetic polymorphisms that are associated with sprint/power or endurance performance as well as maximum oxygen uptake and muscle fiber type. We also identified several genetic polymorphisms that is associated with sprinting performance by using candidate gene approach. Moreover, we found sports performance-related polymorphisms, namely, ACTN3 R577X and ACE I/D, were associated with human muscle fiber composition.
