(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.

This genotype indicates better performing muscles, [PMID 18043716] particularly for sprinting and power sports. Fast-twitch muscle fibers are able to produce alpha-actinin-3. Professional sprinters usually have this, although it is less common for endurance athletes.
