Outline of Final Research Achievements

The aim of the present study were 1) to investigate the association between the ACTN3 R577X genotype and elite athlete status in a large Japanese cohort of track and field athletes. 2) to investigate the effects of the MCT1 T1470A polymorphism on power-oriented performance and lactate concentration during or after cycling sprints in Japanese wrestlers. One-thousand fifty-seven Japanese track and field athletes (627 sprint/power athletes and 430 endurance athletes) and 810 Japanese controls in study 1 and 199 wrestlers in study 2 were genotyped for ACTN3 R577X genotype and e MCT1 T1470A genotype using the TaqMan Assay. The data obtained for track and field athletes served to confirm the association between the RR + RX genotype of the ACTN3 R577X polymorphism and elite sprint/power athlete status. The AA genotype of the MCT1 T1470A polymorphism is associated with athletic performance and lower blood lactate concentrations after 30s WAnT and during intermittent sprint tests.
