Citius and longius (faster and longer) with no alpha-actinin-3 in skeletal muscles?

British journal of sports medicine - 1 Sept 2007

Abstract excerpt

The muscle protein alpha-actinin-3 (ACTN3) is normally thought to be expressed in type II muscle fibres and to be necessary for high-power, high-velocity muscle contractions, such as those typically seen in speed/power athletes. The authors report the case of a Spanish elite long jumper (two times Olympian, personal best of 8.26 m) whose genotype for the ACTN3 gene is 577XX (ACTN3 deficient). These data suggest...
