About Testosterone & Muscle Growth

Function Testosterone is a member of a group of hormones known as androgens, which are responsible for starting and directing the growth and development of male sexual traits during puberty, though they also play a role in the growth and development of females. In adults androgen levels are related to muscle mass, sex drive and aggressiveness. Testosterone, in particular, plays a key role in regulating muscle mass and the body's response to exercise. However before this role can be understood we must explore how the body builds muscle in the first place. Background Resistance exercise and other strenuous physical activities trigger muscle growth by causing small amounts of trauma to the muscles themselves. In response to this stimulus, the body adapts by repairing the muscular tissue and increasing its strength and size by adding new protein strands to muscle fibers.This process is called protein synthesis, and it is modulated by a variety of hormones called growth factors, of which testosterone is one of the most important. Effects Testosterone directly effects muscle growth by binding to receptors on the surface of muscle cells and amplifying the biochemical signals in muscle tissue that result in protein synthesis. Testosterone also increases levels of another growth factor, called growth hormone, that the body releases in response to exercise. Like testosterone, growth hormone increases protein synthesis and can result in increased muscle growth. Orginal Article - http://www.livestrong.com/article/68797-testosterone-muscle-growth/

Quality protein is critical for muscle fiber growth and rejuvenation (Opinion)





What Constitutes High Quality Protein High quality protein is completely whole and non-denatured. It contains essential vitamins, minerals, enzymes and other natural co-factors. These components are very important for overall amino acid utilization and energy production. Protein digests to form an acidic ash. These co-factors help provide alkaline substances that maintain normal acid/base balance. There is a tremendous amount of processing that takes place to produce a protein isolate. It is completely unnatural. This processing strips out the natural proteolytic enzymes, minerals, & anti-oxidants. This reduces overall bioavailability and creates a highly acidic and inflammatory food product. Orginal Article - http://www.naturalnews.com/033934_protein_muscle_growth.html





Muscle Growth in Teenagers





Scientists in Australia believe they have found one of the molecular keys to a protein that promotes weight and muscle mass gain - without any exercise involved. Researchers have found that by blocking the function of Grb10 - nicknamed the 'Hulk' protein - while mice were in the womb, they were considerably stronger and more muscular at birth than normal mice. Mr Muscles: Getting toned like the Incredible Hulk will be a thing of the past if the protein discovered by scientists helps muscle growth in humans The study, published in the September issue of the respected FASEB Journal, has important implications for a wide range of conditions such as muscular dystrophy, Type 2 diabetes, and problems produced by muscle inflammation. One in a hundred children are 'psychopathic', warn researchers - and they say there is nothing parents can do to control them Grb10 seems to have a significant role in promoting muscle growth without any change in activity, diet, or adverse health effects, according to researchers. 'By identifying a novel mechanism regulating muscle development, our work has revealed potential new strategies to increase muscle mass,' said Lowenna J. Holt from the Diabetes and Obesity Research Program at the Garvan Institute of Medical Research in Sydney. Holt and her colleagues compared two groups of mice. One with the Grb10 gene and the other where it was blocked. Working out: No more gym work may be on the cards following tests on mice which showed the blocking of a protein helped muscle growth Researchers examined the properties of the muscles in both adult and newborn mice and discovered that the increase caused by the loss of Grb10 had mainly occurred during prenatal development. These results suggested that it may in future be possible to alter muscle growth and help faster healing, as the processes involved in muscle regeneration and repair are similar to those for the initial formation of muscle.

Death of the gym workouts? 'Hulk' protein discovered by scientists that could be behind huge muscle growth





The growth spurt accounts for about 20 percent of the full adult height in both sexes. Teens will gain approximately 50 percent of their ideal adult weight during puberty, including an increase in lean muscle mass. The skeletal will continue to increase into adulthood for males. Lean muscle mass will decrease for females after puberty, giving way to increased body fat. Want to get in great shape? Learn more about LIVESTRONG.COM's nutrition and fitness program! Causes Weight training is the most recommended method to increase muscle mass, lower body fat, improve strength and muscle tone and build bone density, according to Muscle and Strength. Young teenagers start out with moderately heavy weights, increasing the work load as they mature. The primary objective of the initial weight training is to build muscle mass. Simple exercises such as squats, bench presses and dead lifts train and strengthen large muscle groups. Orginal Article - http://www.livestrong.com/article/301122-muscle-growth-in-teenagers/
