The Genetics of Muscle Building

      Genetics are accountable for each person's stature, muscle fibers. and how well the body responds to different kinds of training. A lot of hard work, a specific diet, and smart training is of course an important factor in how much muscle a person gains as well. However, in response to training each person's body can react differently and genetics can provide an explanation for these differences. This is why it is important for a person to dedicate themselves if they are aspiring to make changes to their body. A lot of trial and error and learning is incorporated into training due to the fact that every person must train differently. Results seen in the gym have a correlation to the efficacy of satellite cell-mediated myonuclear cells (Conteras, 2011). Mechanogowth factor, Myogenin, and IGF-IEa are indicator genes that effect the way muscles respond as well (Conteras, 2011).

  1. I think that this article is very interesting because we are able to see that some people have different genes coding for how they build muscle. If two genetically different people worked out together and underwent the same training, they most likely would have a much different build in muscle.

  2. This article is super interesting, especially because I personally love to go to the gym and get involved in sports/physical activities. Having this knowledge can benefit from understanding which muscle is being focused on at the gym, as well as what genes allow the muscles to respond in this way.

  3. almost seems unfair that some people are more predisposed to acquiring a desirable physique, but i guess that is just the unbiased actions of genetics and biology at work so we'll just have to hit the gym and deal with it.
