For years people have been searching for answers on how to get massive hypertrophic gains and maintain them. Over the last several decades’ people have resorted to using anabolic steroids and large consumptions of protein to solidify their gains. Within the last few decades a new stain of protein part of the myokine family has recently been discovered that can give you all the gains your heart desires. Myostatin was first discovered in the late 1990’s by geneticists Se-Jin Lee and Alexandra McPherron who produced a strain of mutant mice that lacked the gene. These mice that they were working became known, as “might mice” because they had more than twice the muscle mass of a normal everyday mouse. This specific targeting of myostatin that was …show more content…
GDF8 in particular is responsible for the growth seen in muscle tissue. Myostatin has been found almost entirely in muscles used for movement such as your skeletal muscles, where it can be found in an active state both before and after birth. This protein has predominantly been known for its restraint of muscle growth, ensuring that muscles do not grow too large. Although myostatin is a fairy new discovery and we don’t know much about it there are a few things that we have learned. The MSTN (myostatin) gene can be found in virtually ever living mammal and is responsible for ensuring that the muscle does not grow to large but there have been some studies found where some have lacked the MSTN gene and have had significantly larger muscles than the average person. The mutation is caused when the gene responsible for making myostatin receives little to no signals or a change in the gene known as IVS1+5G>A, which leads to little or no production of the gene. The minimal production of this protein often leads to the overgrowth of muscle tissue but has not be known to cause any other medical
production. The patient could start seeing gains in lean body mass with only an increase of
Each form of muscular dystrophy is caused by a defect in a specific gene. In 1986, scientists discovered exactly which piece of genetic material is missing in Duchenne muscular dystrophy patients. They named it for Guillaume Benjamin Amand Duchenne(1806-1875), a French neurologist who was one of the first doctors to discover and study the disease. When functioning properly, the Duchenne gene carries instructions for assembling a muscle protein known as dystrophin. At about 2,500,000 nucleotides, dystrophin is one of the largest genes known. Dystrophin is largely responsible for reinforcing and stabilizing the sarcolemma. Dystrophin associates with the muscle fiber sarcolemma by interacting with the actin microfilaments and with a transmembrane protein complex linked to the extracellular matrix. This latter dystrophin-associated glycoprotein complex (DAGC) includes the extracellular proteoglycan, [Alpha]-dystroglycan, which binds to merosin in muscle fiber basal laminae, as well as a number of other integral and cytoplasmic membrane proteins: [Alpha]-dystroglycan; [Alpha]-, [Beta]- and [Gamma]- sarcoglycans (see Figure 1). The DAGC provides a physical link and, potentially, a signaling pathway between the extracellular matrix and the internal scaffolding of the muscle cells. Mutations in the Duchenne gene result in dystrophin deficiency, which constitutes the pathogenic basis of DMD. Dystrophin is either absent or severely deficient in a person with DMD. When dystrophin is lost through gene mutation, the muscle falls apart under the tension generated when it contracts. Without dystrophin, the muscle fibers also lose their ability to regenerate and are eventually replaced with adipose tissue and fibrous connective tissue (see Fig. 2 and Fig. 3).
(Chamberlain, 2002; Nowak, 2004) Nowak and Davies (2004) identified a number of promising treatment approaches which include “gene therapy […] using plasmids or viruses, [so that] mutations can be corrected using chimaeraplasts and short DNA fragments, [and] exon skipping of mutations can be induced using oligonucleotides and readthrough of nonsense mutations […] using aminoglycoside antibiotics. [Furthermore,] blocking the proteasome degradation pathway [as a way to] stabilize any truncated dystrophin protein, and upregulation of other proteins [to] prevent the dystrophic process. Muscle [could also] be repopulated with myoblasts or stem
Whey protein, which is a key ingredient in this supplement, can be found in common foods and it is unnecessary to only derive them from these outside supplements. For example, in order to gain the same results as taking the Muscle Milk supplement, one can consume a glass of chocolate milk immediately after exercising. Whey protein is found in milk and sugar in the chocolate, a ratio of 1 to 4, is the ideal combination to maximize protein synthesis (Girandola). This healthy alternative can be taken to avoid the potential side effects of consuming Muscle Milk while still gaining lean muscle mass. The overall results affirmed that Muscle Milk’s claims of gaining lean muscle mass and recovering from exercise are accurate, however, the side effects and possible consequences of the supplement are not worth the gain it would
Resistance training is hard work and requires a lot of energy and juices out of the human body, which cannot be replenished as fast as desired; however, there is a solution to the soreness and the slow path to gaining muscle mass: Weight-Training/Performance supplements. Athletes across the world take performance supplements every day typically in some form of protein supplement, whether it be whey protein or protein derived from vegetables or soy-based. The determination of whether such supplements that are not regulated by the FDA have more positive effects than negative is still a considerable debate; although, the effects cannot be denied after ingestion. The positive effects of supplement use is far more beneficial than not taking them at all because of the increased stimulation and maintenance of muscle growth when taking whey protein and other supplements.

MuscleTech’s philosophy is to be known as the world leader in sports nutrition and to support this they fund university research to better understand muscle metabolism, biochemistry, fat oxidation and performance. They want to be able to increase lean muscle mass and by so doing increase muscle strength. In fact, they have a multi-million dollar partnership with the University of Toronto to develop the MuscleTech® Metabolism & Sport Science Lab which is part of the 58 million dollar Goldring Centre for High Performance Sport. This science lab will be developing new ingredients for the sports arena by making use of new technologies and equipment. The lab will be open in the fall (2016). No doubt, the research produced in this arena will be far reaching not only for high performance sport enthusiasts
For this genetic disorder assignment, I chose Marfan Syndrome, which is a mutation in your connective tissue. Connective tissue holds our body together by holding the blood where it is suppose to be, the organs in place and keep our tissue in place. This connective tissue also helps you grow in height and go through the stages you need to. The disorder results in abnormally long and thin digits in your genes and also frequently in optical and cardiovascular defects. Our connective tissue is made up of many proteins and the protein that affects Marfan Syndrome would be fibrillin-1, which in this disorder is a defect in the body on how to make this protein. The Transforming Growth Factor Beta (TBF-β) protein takes

The supplement industry is a multi-billion-dollar industry that only continues to skyrocket. Due to the increase, the Food and Drug Administration (FDA) has found it hard to keep up with the ability to regulate. In turn, producers do not have to obtain authorization from the FDA when they want to market or sell any nutritional enhancements. Thus, I think it is important to be well informed on these products, as well as how they influence and affect our bodies. Nevertheless, while a supplement should essentially be safe to humans, the FDA's role in regulating muscle building, weight loss, and other nutritional enhancements is principally one based off of examination and supervision. In turn, When the FDA determines that a dietary supplement poses a health risk to people, it can issue a recall or take other actions to limit the product's use or sale. Nevertheless, it must reach that point. In turn, it is important to be well educated and monitor what we are putting into our
Because Muscular Dystrophy is a genetic abnormality causing lack of muscle proteins, the symptoms and treatment (or management) have an impact on everyday life.
Muscle development or myogenesis is a complex and regulated process, the end result of which is the formation of a multinucleated myofiber. Significant control of skeletal muscle development depends upon the muscle basic helix-loop-helix (bHLH) gene family known as myogenic regulatory factor (MRF), which includes MyoD, Myf-5, myogenin, and MRF4 (Parker M.H. et al., 2003) (Fig. 1), and the negative helix-loop-helix (HLH) regulators, Inhibitor of differentiation proteins (Ids) (Hasskarl J. and Munger K. 2002). MyoD and Myf5 serve as early myogenic regulatory factors and they mark the myoblast commitment to differentiation. It has been shown that expression of MyoD in non-muscle fibroblast cells can convert them to myogenic cells by activating

When most people hear the term ‘bodybuilding’ they think of massive, inhuman looking individuals, mostly males, who spend every waking minute in the gym lifting weights and injecting steroids. But that is not entirely true. Bodybuilding is much more complex than that, especially when it comes to nutrition. Bodybuilding is a lifestyle. There are many different factors that come in to play for professional bodybuilders, as well as the regular person who is looking to put on muscle mass or whatever their fitness goals might be. Some of those factors include nutrition, training, recovery, supplementation, as well as the controversial topic of drugs in the bodybuilding scene. Bodybuilding also has a unique history that should be addressed before diving into the topics of bodybuilding.
Proteins are extremely important in the growth of muscles, combined with weight training; protein can enhance muscle mass gain. Dependent on the athlete, the balance between weight lifting and protein intake will vary; a professional or trainer will measure the needed amount. Thought, all athletes will need a high protein diet, short track sprinters will not intake as much as much as a football player, for the sprinter would have a high carbohydrate diet. Resulting in instant energy opposed to the football players need for muscle mass and stored energy for long exercise periods.
A lot of people are trying to build muscles in their body by working out. They work out by lifting heavy weights. However, when working out to building muscle, one needs to consume healthy foods and more proteins. After finishing a workout, the muscles in the body have microscopic tears to form in the fiber and connective tissues. This will cause the muscles to be tired and damaged. To repair the muscle, consume healthy foods and more protein. When one get enough foods in the body, the muscles will use the nutrients from the foods consumed and slowly rebuild, resulting in muscles in the body to increase size, strength, and muscle capacity. When I was in grade 9, I started to lift weight and I was new to it. After a few days of working out my body was experiencing any change. I realized that the reason my body was not experiencing change is because of what I was eating. I was not eating much protein and healthy foods. Later I started to eat foods that contain high protein and then I started to experience change, my muscles were getting bigger and stronger. Foods that contain high in protein can help to build muscles such as cottage cheese, chicken breast, whole eggs, canned tuna, etc. So therefore, having enough protein is the main key in order to build
