That makes sense from an evolutionary perspective, Lindholm said. They took nine months off, then returned to repeat the training, but this time with both legs. "Your nerves have learned in which order to activate your muscles in order to perform a certain movement," she said. A few hints suggested that training may have induced some lasting epigenetic changes, or changes in chemical markers on the genes that affect how they are expressed, but the results were too tentative to say for sure. The team took muscle biopsies (which involves anesthetizing the skin and using a needle to extract muscle cells) both before and after both exercise training periods, and analyzed which genes were active in the muscle tissue in each leg. The research has important implications in how athletes train, recover from injury, and also has potentially far-reaching consequences for athletes caught cheating. Further research will be important to understand how different exercise programmes can help activate these muscle memory genes.”, “If an elite athlete takes performance-enhancing drugs to put on muscle bulk, their muscle may retain a memory of this prior muscle growth.

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. "If … “If an athlete’s muscle grows, and then they get injured and lose some muscle, it may help their later recovery if we know the genes responsible for muscle 'memory’. A new study suggests that muscle memory may not really exist. Periods of skeletal muscle growth are ‘remembered’ by the genes in the muscle, helping them to grow larger later in life. "If an athlete's muscle grows, and then they get injured and lose some muscle, it may help their later recovery if we know the genes responsible for muscle 'memory'. IE: If an elite athlete takes performance-enhancing drugs to put on muscle bulk, their muscle may retain a memory of this prior muscle growth," says Seaborne. or, by Keele University. part may be reproduced without the written permission. More research using drugs to build muscle, rather than exercise used in the present study, is required to confirm this.".

That may be both good news and bad news for people, said study co-author Malene Lindholm, a molecular exercise physiologist at the Karolinska Institute in Stockholm. When you start exercising, "you can adapt just as well as people who have trained," she said.
Your opinions are important to us. And, over the longer term, if people continue to work out, the body starts making more proteins and that leads to more long-term adaptations. 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. March 18 2013.
The research, published in Scientific Reports - Nature, 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. Muscle tissue does not have a "memory" of past exercise training, new research suggests. "It's a cost to keep up really metabolically active muscles or a big muscle mass, and there is no reason for the body to expend energy on that if we don't need to use the muscle," Lindholm said.

Known as epigenetic modifications, these 'markers' or 'tags' tell the gene whether it should be active or inactive, providing instructions to the gene to turn on or off without changing the DNA itself.
