Protein For Exercise And Recovery: Where Do We Stand? One of the leading researchers on the effects of protein intake on exercise performance, fitness adaptations and recovery is Richard Kreider at Texas A&M University. Kredier has authored a new review of research in his area of expertise summarizing what we know. Here's the abstract of his paper: "Dietary protein is required to promote growth, repair damaged cells and tissue, synthesize hormones, and for a variety of metabolic activities. There are multiple sources of proteins available; however, animal sources of protein contain all essential amino acids and are considered complete sources of protein, whereas plant proteins lack some of the essential amino acids and are therefore classified as incomplete. There is a significant body of evidence to indicate that individuals who are engaged in intense training require more dietary protein than sedentary counterparts (i.e., 1.4-2 g/kg/day). For most individuals, this level of protein intake can be obtained from a regular and varied diet. However, recent evidence indicates that ingesting protein and/or amino acids prior to, during, and/or following exercise can enhance recovery, immune function, and growth and maintenance of lean body mass. Consequently, protein and amino acid supplements can serve as a convenient way to ensure a timely and/or adequate intake for athletes. Finally, adequate intake and appropriate timing of protein ingestion has been shown to be beneficial in multiple exercise modes, including endurance, anaerobic, and strength exercise." For years post-exercise nutrition for athletes was all about carbohydrates. However, within the last 10-15 years leading exercise physiologist have come together to formulate sports nutrition products based on the very latest science and as a result companies like PacificHealth Labs (Accelerade) and now Gatorade (G-series) have developed products that are a combination of carbhydrate and protein formulated to significantly enhance hydration, increase endurance, reduce exercise-related muscle damage and accelerate post-exercise muscle recovery. However, for athletes, nothing beats a balanced diet of carbohydrate, protien, fat, vitamins, minerals and fiber in the correct proportions. Remember sports nutrition supplements are just that supplements - although they may aide in your training they are not intended to replace a proper diet.
