Young Athletes’ ACTN and PPAR Genes Help Performance, Too

The presence of Actin (ACTN) and Peroxisome proliferator-activated receptor (PPAR) gene families is frequently mentioned in literature reports and news articles. This extends to young athletes as well: Boys with ACTN3 RR genotype tended to swim faster (25m and 100m) (34) regardless of training status. The R allele was also associated with better 40m sprint performance … Continue reading Young Athletes’ ACTN and PPAR Genes Help Performance, Too
