What is Sarcopenia?

If you are looking for a way to increase the amount of muscle that you have you may be looking for a way to learn how to get protein for your diet.The fact of the matter is that most people do not get enough protein in their diet on a daily basis. There is actually a way that you can determine how much protein you need to stay healthy. As a general rule you need about 1 g of protein in your diet for every pound of body weight that you have. If you weigh close to 200 pounds of body weight, it may be difficult for you to get this much protein in your diet from natural sources. However, there are other sources of protein that you can get that are healthy for your body that are not from natural sources. One of the best ways that you can get protein for your diet is by taking a protein supplement. One of the best protein supplements is that GNC protein supplement. This is an extremely healthy protein supplement because it is made of 100% whey formula. You should never take a protein supplement that is not made of whey formula. The reason for this is that many of these other protein supplements contain hormones that can be harmful to your

If I were a seventy year old man I would need to increase my intake of all food groups except the high fat and cholesterol. I would need lean meats and fish to avoid the cholesterol increasing foods. Depending on kidney function I would eat large amount of protein as well to keep the healing process available for the aging body. According to the

Leucine is commonly regarded as being the most important amino acid in the BCAA supplement combination. For this reason, some BCAA supplements contain an 8:1:1 or even 10:1:1 ratio of leucine to other amino acids. However, it is important to note that a higher leucine content does not necessarily boost muscle growth better than supplements with a low-leucine-to-other-amino-acid ratio. In fact, one study shows that the BCAA capsules that were most effective were the ones with a mere 2:1:1

The biological value in whey protein enhances the body’s ability to absorb essential amino acids after resistance training decreasing the athlete’s recovery time. When athletes combine whey protein and creatine monohydrate they expect “a greater increase in lean tissue mass and muscular strength than supplementations with whey protein alone” (Burke, Chilibeck, Davison, Candow, Farthing, & Smith-Palmer 2001, p 350). Exogenous Cr supplementation increases the body’s Cr levels until saturation occurs. This saturation of Cr increases the PCK shuttle continuum allowing training intensity, volume, and duration of the exercise the athlete is performing to continue at a maximum rate. Any excess Cr in the blood is cleared through sweat, urination or renal filtration. Measurements in strength and peak torques of athletes supplementing with whey protein and creatine monohydrate (WC), whey protein (W), and a placebo (P) were taken. According to Burke et al, (2001) “repeated measure analysis of variance was used to assess changes in body composition, strength, and peak torque for the three groups (WC vs. W vs. P) across time” (p. 354). A twelve week strength training program was constructed and consisted of a “4-day split routine involving whole body musculature” (Burke et al, 2001. p 352). Subjects used detailed training logs to compare progress over the 12 week experiment. The end result from this experiment shows that subjects who “supplemented with both creatine and whey

Apart from protein supplementation, consume the diet enriched with protein such as meat, eggs, skimmed milk, and fish as they contain the essential amino acid which are also added in a trace form into some of very famous muscle building supplements.

For everyone, especially active athletes and bodybuilders, natural proteins are the best source for someone who is interested in accelerating muscle growth. Protein is a nutrient used for the maintenance and repair of a person's body. You can find natural proteins in the foods we eat and therefore consume high protein foods.

. Skeletal muscle make up 50% of total body protein, a compelling loss of skeletal muscle mass deteriorates metabolism, immunocompetence and strength. (Muller et al.) Muscle mass is age dependent, after the age of 50 it is expected that

With a scientifically formulated combination of amino acids, designed to promote muscle growth and energy production, prepare to tackle training with unmatched

As humans grow older, both muscle mass and bone density decrease. This deterioration of muscle mass, also known as sarcopenia, is often accompanied by a loss of function and strength. This significant loss of muscle that occurs with aging can impair functional ability for the elder population, which can include everyday tasks such as opening a jar, walking down stairs, or bending down to pick an item up. The most practical approach to combat deteriorated muscles is to incorporate some type of strength or resistance training into the daily schedule. One of the strength methods tested was explosive-type heavy resistance training, which may alter kinetics and neuromuscular activity during stair ascent in elderly women (Holsgaard-Larsen, Caserotti,

More and more people each year die of an age related disease. One of these diseases is as simple as aging. But what people don’t realize is that no matter what diet they have, exercise is extremely essential for developing healthy muscles as the years go by. The amount of skeletal muscle fibers that people have as kids, and/or young adults can degenerate as people age and lack/decrease in exercise/weight training. The healthy human muscle has the ability to flex and contract and is not very easy to break opposed to an unhealthy human muscle with low muscle fiber levels.

One topic that has grown great interest in the health field is a disease known as sarcopenia. Sarcopenia is a complex disease and is defined as a loss in skeletal muscle due to aging. Since this disease is associated with biological aging, it is found in the elderly. It is expected to triple in people who are over the age of 60 in the next 50 years, which is why it has sparked an interest in research. There are multiple factors that can cause this muscular dystrophy in aging adults which will be discussed in this paper as well as, understanding homeostasis of skeletal muscle mass, treatments for sarcopenia, and the individuals who are at risk of forming sarcopenia.

Oxidation of these amino acids occurs in skeletal muscles. Though BCAAs are not used as a source of energy in the body under normal conditions, they do contribute to energy generation during heavy and strenuous exercise. The subsequent breakdown of these amino acids for energy generation during heavy exercise leads to muscle damage and tear. Therefore, restoring them with the help of protein supplements is extremely necessary to make up for the loss of proteins.

According to Cooke, Rybalka, Stathis, Cribb, and Hayes (2010), there are many benefits of whey protein, such as providing nutrients, repairing muscles, and assisting in packing on muscle mass. Whey protein is fueled with a plentiful source of amino acids. Branched chain amino acids (BCAA’s) are in full effect whenever muscle synthesis begins the muscles growth process. One of the main branched chain amino acids is Leucine. Leucine is required in whey protein for optimal repairing and growth of muscles. Amino acids are plentiful in protein due to muscles putting off acid in post workout activity. Consuming whey protein will play a major role in replenishing the acid lost due to excessive muscle building (p. 1-8). (Cooke et al., 2010) stated that, “Stimulating protein synthesis and minimizing protein breakdown (proteolysis) are the two cellular processes

Branched Chain Amino Acids (BCAAs) are composed of three essential amino acids including leucine, isoleucine, and valine. They are unique in that they are predominantly metabolized outside of the liver in the skeletal muscle. BCAAs make up 35-40% of the amino acid pool in the body and exist in high concentrations in skeletal muscle tissue (Shimomura et al, 2006). While the supplemental dosage is dependent upon on the type of exercise,, body composition, and dietary intake, a standard dosage of the combination of BCAAs is 20g, of leucine, isoleucine, and valine. Other ratio combinations are available as well as individual supplement products of leucine and isoleucine. BCAA supplementation is often taken before, during, and after exercise. It has been observed that BCAAs potentiate the effects of exercise by their anabolic processes on protein metabolism by increasing the rate of muscle protein synthesis and decreasing the rate of muscle protein breakdown (Karlsson et al., 2004). Moreover, it has been theorized that BCAAs may improve performance, reduce muscle fatigue, and feelings of muscle soreness.

The RDA for protein for seniors is 12-14% of the diet.  Protein is needed to build and maintain body tissues, and these needs increase for individuals during illness and after surgery (8).  Although fat digestion decreases with age, a small amount of fat is still necessary since it is a concentrated energy source and transports vitamins.  No more than 30% of total calories should be from fat.  Carbohydrates should make up 50% of daily calories, and 25-35 grams of fiber should be eaten to prevent GI stress.  Overall, caloric needs decrease with age, generally a 10% reduction between the ages of 51-75 and up to a 15% reduction after age 75 (8).  These needs are not exact; they are dependent on both activity level and body composition.
