Study Proves 'Muscle Memory' Exists at A DNA Level
Published:08 Feb.2018    Source:Science Daily
A study led by researchers at Keele University has shown for the first time that human muscles possess a 'memory' of earlier growth -- at the DNA level. Periods of skeletal muscle growth are 'remembered' by the genes in the muscle, helping them to grow larger later in life. The research, published in Scientific Reports, could have far-reaching implications for athletes caught using performance-enhancing muscle building drugs -- as the drugs could be creating long-lasting changes, making short-term bans inadequate.
 
Using the latest genome wide techniques, the researchers from Keele, along with the Universities of Liverpool John Moores, Northumbria and Manchester Metropolitan, studied over 850,000 sites on human DNA and discovered the genes 'marked' or 'unmarked' with special chemical 'tags' when muscle grows following exercise, then returns back to normal and then grows again following exercise in later life.
