Geno	Mag	Summary
(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.
