摘要：

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 that there might be notable exceptions to the concept that ACTN3 is the "gene for speed''.
