Key result
ACTN3 R577X polymorphism shows no link to explosive leg muscle power in volleyball players or controls.
Why the study?
The influence of the ACTN3 R577X polymorphism on explosive leg muscle power in elite volleyball players was unclear.
Does the ACTN3 R577X polymorphism influence explosive leg muscle power in elite volleyball players?

Null ACTN3 R577X association with jump power in volleyball players; leaves open its relevance for other performance or injury phenotypes.
Ruiz et al. (2010) conducted a case-control in Healthy (Elite volleyball players and non-athletic controls) (n=400). ACTN3 R577X polymorphism (rs1815739) vs. Different genotypes (RR vs RX+XX, RR+RX vs XX) was evaluated on Explosive leg muscle power performance (vertical squat and counter-movement jump tests) (p=>0.05). The ACTN3 R577X polymorphism did not influence explosive leg muscle power in elite volleyball players or non-athletic controls (all P>0.05).
