Abstract

The knowledge of muscle function plays a major role in bodybuilding training and makes big difference for bodybuilders.Muscle monitoring is of great interest in areas such as clinical assessment, and sport science. Understanding, ideally quantifying, when a muscle state has changed in relation to whole body motion can assist in physical training and muscle conditioning.There are lot of different methods to gain muscle mass and improve weak parts; bodybuilders been using those methods for decades such: dropset, rest-pause, super-set, tri-set, giant sets, contrast time, multi hold pump set, intra set load contrast, regressive range of motion, iso dynamic contrast. Our method is based on scientific work; our main goal is to improve bodybuilder’s weak muscles and increase muscle mass in very short period of time, to asses our work we used electromyography (EMG) to assess the skeletal muscles activity and ultrasonography (US) to measure muscle thickness.

Bodybuilding is the use of progressive resistance exercise to develop the musculature, is the process of developing muscle fibres through the combination of weight training, increased caloric intake, and rest. Bodybuilding decreases risk of developing diseases, Improve Mental Health, simply Weight training exercise, aerobic exercise and right nutrition have beneficial effects for strong mind and body. Muscle hypertrophy is a term for the growth and increase of the size of muscle cells. Hypertrophy is, by definition, the enlargement of an organ or tissue from the increase in size of its cells. Not to be confused with hyperplasia, the process of increasing the number of cells, hypertrophy is the process of increasing the size of the cells that are already there.By that a hormonal response is triggered, so a release of growth factor, cortisol, and testosterone. Growth factors help stimulate muscle hypertrophy while testosterone increases protein synthesis. This process makes satellite cells multiplying and their daughter cells go to the damaged tissue. To build muscle through weightlifting, you need to have both mechanical damage and metabolic fatigue. When you lift a heavy weight, the contractile proteins in the muscles must generate force to overturn the resistance provided by the weight
