IntroductionScientists, coaches, and athletes have recognized that periodized strength training promotes increased skeletal muscle size, increased strength, and Increased regeneration capacity of muscle cells. Many scientists confirm that nutrition and dietary supplementation can profoundly affect the molecular and cellular processes that occur in the body during the exercise and recovery process. This brief review analyzes the potential for performance enhancement through the ingestion of protein supplements and the importance of nutritional education for users of sports supplements. OverviewAccording to the book "Understanding Normal and Clinical Nutrition", the Recommended Dietary Allowance (RDA) for protein intake is 0.8. g/kg body weight for non-athletes; according to nutrition professionals, this amount can be achieved through a healthy diet (Rolfes, Pinna and Whitney, 2012). It is well known that athletes, due to their high energy expenditure, need to ingest a greater amount of nutrients with the aim of repairing and building muscle cells, in addition to restoring energy storage; The International Society of Sports Nutrition (2007) states that the amount of protein consumed by athletes and exercisers depends on the intensity of physical training sessions, the quality of protein ingested in their diet complete, in addition to their carbohydrate intake. At the same time, the protein requirements of athletes should be around 1.4-2.0 g/kg body weight, and while dietary supplements are a safe way to meet protein requirements, it would be healthier to obtain necessary nutrients by ingesting high-quality foods as part of a diet program. daily regimen (Campbell et al, 2007).
