Muscle Hypertrophy or Muscle growth or Bodybuilding is the intentional growth of targeted muscle tissue caused by resistance training.
Using a variety of training methods one is able to achieve muscle hypertrophy. Hypertrophy is an increase in the size of a muscle through an increase in the size of its component cells. Another effect called hyperplasia may be achieved, which refers to an increase in the number of cells or fibers.
A muscle can either grow in size by increasing the diameter of the muscle fibres, whilst the number of fibres remains constant. This is possible only if the muscle is strained beyond a normal performance level. Nerves will fire a growth stimulus, which causes protein deposits in the muscle tissue to increase. If the body responds to training with hyperplasia, it will build new muscle fibres altogether, which may also grow in size at a later stage.
Today one have access to a large variety of supplements in order to achieve faster and more efficient muscle growth and avoid unwanted muscle atrophy (shrinkage) caused by overtraining or poor nutrition.
Amino acids are particularly effective in growing and repairing muscle tissue, because it consists mainly of protein. A large number of natural nutrients are central to the building and maintenance of muscle strength and endurance. For this reason should bodybuilders and other athletes always make sure that they have a comprehensive and balanced diet?
In case of under supply of important nutrients the body will break down muscle tissue to use its components to repair tissue damaged during training. This will result in an unwanted reduction of overall muscle mass (atrophy).
A muscular body also has increased basic energy consumption and therefore needs more energy without actually exercising. Building muscle during when attempting to lose weight is therefore sensible, because larger muscles consume more energy also reducing the possibility of regaining fat afterwards.
