The Genetics of Muscle Growth
article detailing research from the Institute for Aging Research (IFAR) at Hebrew SeniorLife (HSL) provides us with a better understanding about the genetics behind muscle growth. They focused on the genetics of "lean body mass" which is made up of mostly muscle (which is what gives one that massive but chiseled look that body builders have). Unfortunately, heredity plays a big part in growing muscle. This is why one person can work out for years and not achieve the results that another person (who has better genetics) can accomplish within a month of working out. A related article called The Truth About Body Building Genetics delves more into the specific genes that allow for some to gain muscle more easily than others. This research may help us better understand the process of aging and a condition called sarcopenia which results in decreased muscle mass at older age. Isolating the genes responsible for building lean muscle mass may help those affected with this condition so its possible to develop a treatment plan - or even help out the local scrawny gym rat who's frustrated at not being able to make gains like the big guys.
