(C;C) 2.2 Better performing muscles. Likely sprinter.
(C;T) 2.1 Mix of muscle types. Likely sprinter.
(T;T) 2.2 Impaired muscle performance. Likely endurance athlete.

Normal for white people. One working and one defective copy of the gene for alpha-actinin-3 in fast-twitch muscle fibres. This genotype may indicate somewhat impaired muscles,[PMID 18043716] however many sprinters and some endurance athletes have this.
