Key result
ACTN3 genotypes were not significantly associated with power or body composition-related phenotypes in Rugby Union players compared to controls.
Why the study?
Is there a relationship between ACTN3 genotypes and power output or body composition in Rugby Union players?
Population
Rugby Union players (n=102) and a control group (n=110)
Comparison
ACTN3 genotyping vs Control group and within-group comparisons
Design

No ACTN3 link to power or body composition in rugby players; leaves open broader genotype-phenotype associations in elite athletes.

Is there a relationship between ACTN3 genotypes and power output or body composition in Rugby Union players?
ACTN3 genotypes do not significantly correlate with power or body composition phenotypes in Rugby Union players.
Bell et al. (2011) conducted a case-control in Rugby Union players (n=212). ACTN3 genotypes vs. Controls was evaluated on Relationship between ACTN3 genotypes and power and body composition phenotypes. ACTN3 genotypes were not significantly associated with power or body composition-related phenotypes in Rugby Union players compared to controls.
