Introduction
Scientists, coaches, and athletes have recognized that periodized strength training promotes increase in skeletal muscle size, increase in force, and increase of the regenerating capacity of the muscle cells.
Innumerous scientists confirm that nutrition and dietary supplementation can deeply affect molecular and cellular processes that occur in the body during the exercise and the recovery process. This brief review analyzes the potential for performance enhancement through protein supplementation ingestion, and the importance of nutrition education for sports supplement users.
Overview
According to the book “Understanding normal and clinical nutrition”, the Recommended Dietary Allowance (RDA) for protein intake is, 0.8g/kg of body weight for non-athletes; according to nutrition professionals this amount can be achieved through a healthy diet (Rolfes, Pinna, & Whitney, 2012). It is well known that athletes, due to their high energy expenditure, need to ingest a greater quantity of nutrients with the purpose of repairing and building muscle cells, besides reestablishing energy storage; The International Society of Sports Nutrition (2007) states that athletes and exercising individuals amount of protein to be consumed depends on the intensity of the exercise training sessions, the quality of the protein ingested in their whole foods diet, besides their carbohydrate intake. Meanwhile, athletes’ protein needs should be about 1.4 to 2.0 g/kg of body weight, and even though dietary supplements are a safe way to meet protein requirement, it would be healthier to obtain the necessary nutrients ingesting high quality foods as part of a daily diet (Campbell et al, 2007).
While dietary proteins have a very important function...

Creatine Monohydrate Supplementation Essay

- Creatine Monohydrate Supplementation Creatine is a metabolite that is produced naturally by the human body. It is found mainly in the red muscle tissue, but it is also present in the heart and brain. Normally, creatine is acquired through regular dietary intake of products such as meat and fish, which are high in protein. However, when dietary intake is low creatine can be produced from natural amino acids such as glycine, arginine, and methionine in the liver, kidneys, and pancreas. Creatine monohydrate is the synthetic form of creatine (http://creatine-info.com/ - Information on Creatine Monohydrate)....   [tags: Chemicals Anatomy Papers]

- ... 2001, p.358). Creatine increases muscular strength and lean tissue mass, but phosphocreatine absorption can limit the full effect of this ergogenic aid. Diets high in protein from red meat already have a high percentage of CP storage inside the muscle tissue. Vegetarians will benefit greatly from exogenous creatine supplementation because they lack consistent intake of Cr. In an article written by Rawson, Persky, Price, & Clarkson in 2004, “Effect of repeated creatine supplementation on muscle, plasma, and urine creatine levels,” they demonstrated muscle phosphocreatine increases through exogenous supplementation....   [tags: increasing sports performance]

Essay on Applications of Protein Purification

- Protein purification has a variety of applications in drug delivery, tissue engineering, and biointerface science. Elastin-like polypeptides can undergo protein purification so that a single type of protein can be isolated from a complex mixture. Because of the increased demands of peptide-based biomaterials for drug delivery and tissue engineering, efficient protein purification techniques must be used. Four techniques that will be discussed in this report are: Affinity chromatography, Centrifugation-based Inverse Transition Cycling (ITC), Microfiltration-based Inverse Transition Cycling, and finally protein purification by self-cleaving purification tags....   [tags: Protein purification, medical, ]

Protein F : A Protein From The Coffea Canephora Organism Essay

- Protein F is an uncharacterized protein from the Coffea canephora organism, more commonly known as Robusta coffee. Its sequence consists of 420 amino acids, and is coded for by the gene GSCOC_T000168740011. This protein appears to be an aspartate aminotransferase, or an enzyme that catalyzes a reaction of α-ketoglutarate and aspartate to oxaloacetate and glutamate2. Based on a UniProt BLAST search, it appears that the protein is conserved in the organism Theobroma cacao, or cocoa. After analysis of the sequence through an NCBI BLAST search, it can be predicted that Protein F is most likely mitochondrial, especially when compared to similar proteins....   [tags: Protein, Amino acid, Protein structure]
