What is hypertrophy? How Muscle Hypertrophy Helps Build Up Size.

You may have heard that big boys at the gym whirl the word "hypertrophy" when talking about their lift targets – but what does that mean? ean Are the principles behind the term just a sketchy science, a passing fitness fashion or real, laboratory-tested and proven physiology? By definition, hypertrophy is the enlargement of an organ or tissue by the enlargement of its cells. Not to be confused with hyperplasia, the process of increasing the number of cells, hypertrophy is the process of increasing the number of existing cells.

This happens through a physiological process that leads to an increased number of contractile proteins (actin and myosin) in each muscle fiber. With the right training program you can catalyze this process – but it helps to understand the science behind it.

Building larger things

The body has the amazing potential to adapt to its environment. This involves building more force when repeated loading of the fabric indicates that the new higher loads must be absorbed. That's exactly what the strength training process does.

When it comes to building muscle, hypertrophy does not happen by itself. It must be triggered by a physiological need. Hypertrophy can be considered as thickening of the muscle fibers. This happens when the body has been stressed so much that there are larger muscles that can tolerate this new, increased load. This need causes a cellular response of that causes cells to synthesize more materials.
