Postexercise Myostatin and Activin lib mRNA Levels: Effects of Strength Training.

The article presents a study regarding the effects of strength training (ST). The study examined whether post exercise gene expression at the transcriptional level is different in the trained and untrained state. Using novel longtidunal setting, the study determined muscle growth and regeneration-related mRNA expression in response to a single resistance exercise (RE) before and after a strength-training period. The study results indicate that RE-induced alterations in myostatin mRNA expression may have a role in ST-induced muscle hypertrophy.
