Protein and amino acids are among the most common nutritional supplements taken by athletes. This review evaluates the theoretical rationale and potential effects on athletic performance of protein, purported anabolic amino acids, branched-chain amino acids, glutamine, creatine, and hydroxymethylbutyrate HMB. Two books, 61 research articles, 10 published abstracts, and 19 review articles or book chapters. Dietary supplementation of protein beyond that necessary to maintain nitrogen balance does not provide additional benefits for athletes.

Ingesting carbohydrate with protein prior to or following exercise may reduce catabolism, promote glycogen resynthesis, or promote a more anabolic hormonal environment. Whether employing these strategies during training enhances performance is not yet clear. There is some evidence from clinical studies that certain amino acids e.
Branched-chain amino acids leucine, isoleucine, and valine and glutamine may be involved in exercise-induced central fatigue and immune suppression, but their ergogenic value as supplements is equivocal at present. Most studies indicate that creatine supplementation may be an effective and safe way to enhance performance of intermittent high-intensity exercise and to enhance adaptations to training.
Supplementation with hydroxymethylbutyrate appears to reduce catabolism and increase gains in strength and fat-free mass in untrained individuals initiating training; as yet, limited data are available to decide how it affects training adaptations in athletes.
Of the nutrients reviewed, creatine appears to have the greatest ergogenic potential for athletes involved in intense training. All supplements reviewed here need more evaluation for safety and effects on athletic performance.
Amino acids arealso involved in numerous metabolic pathways that affect exercisemetabolism. Consequently, it has been suggested that athletesinvolved in intense training require additional protein in the dietor that they should supplement their diet with specific amino acids. I review here the rationale and the evidence for the potentialergogenic effect of short-term supplementation with protein and aminoacids and the evidence for the potential anabolic effect oflonger-term use when supplementation is combined with training.
Ideal first with protein, then with the amino acids under thefollowing headings: These additional references arereviewed elsewhere Kreider, ; Kreider, ; Williams et al.

This protein intakeis about 1. On the other hand, ingesting more proteinthan necessary to maintain protein balance during training e. Thesefindings indicate that athletes typically do not need to supplementtheir normal diets with protein, provided they ingest enough qualityprotein to maintain protein balance.
More recently, there has been interest in determining the effectsof pre- and post-exercise carbohydrate and protein feedings onhormonal responses to exercise Cade et al.
Consequently, ingesting protein and carbohydrate prior toexercise may serve as an anti-catabolic nutritional strategy Carli et al.

Summary of Branched Chain Amino Acids Primary Information, Benefits, Effects, and Important Facts. Branched Chain Amino Acids (BCAAs) refers to three amino acids: leucine, isoleucine, and valine. For people with low dietary protein intake, BCAA supplementation can promote muscle protein synthesis and increase muscle growth over time.

Amino acids are the building blocks of protein, and are found in many food sources. Some amino acids can be made by your body, but others, known as the "essential amino acids," must be obtained through food or supplements.
