Amino Vital® - The Science of Amino Acids in Sports Nutrition


AMINO ACIDS PREVENT MENTAL FATIGUE AND IMPROVE MENTAL CLARITY Blomstrand E., Amino acids and central fatigue. Amino Acids. 2001 Discussion of multiple studies in both animals and humans explaining the neurochemical properties of mental fatigue and how consuming amino acids positively influence it. HOW BRANCHED CHAIN AMINO ACIDS POSITIVELY INFLUENCE PROTEIN SYNTHESIS AFTER EXERCISE Blomstrand E. et al, Branched-chain amino acids activate key enzymes in protein synthesis after physical exercise, J Nutr. 2006. A study and detailed biochemical discussion demonstrating how BCAAs positively influence protein synthesis in human muscle and recovery after endurance exercise. HOW LEUCINE POSITIVELY INFLUENCES STRENGTH AND ENDURANCE IN EXERCISE Crowe MJ et al, Effects of dietary leucine supplementation on exercise performance, Eur J Appl Physiol. 2006. A study of 13 human subjects and detailed biochemical discussion of the positive effects of six-weeks of regular supplementation of leucine on exercise performance and endurance. HOW NUTRITION POSITIVELY INFLUENCES MENTAL FATIGUE IN EXERCISE Davis J et al, Possible mechanisms of central nervous system fatigue during exercise. Medicine & Science in Sports & Exercise: 1997. Detailed biochemical discussion describing the current facts and hypotheses of mental or central nervous system fatigue during and after exercise. Evidence suggests that decreases in specific neurotransmitters during prolonged exercise delays fatigue, and that certain nutritional supplements designed to minimize the synthesis of specific neurotransmitters during prolonged exercise improve endurance performance. THE POSITIVE INFLUENCE OF BRANCHED CHAIN AMINO ACIDS ON MUSCLE SORENESS AND RECOVERY AFTER EXERCISE Jackman SR et al, Branched-chain amino acid ingestion can ameliorate soreness from eccentric exercise. Med Sci Sports Exerc. 2009. Study involving 24 humans doing weight training that demonstrated how BCAA supplementation reduced muscle soreness. Detailed discussion of biochemical processes, study design and other results are included in the paper.		POSITIVE SYNERGY OF BRANCHED CHAIN AMINOS COMBINED WITH ARGININE AND GLUTAMINE Ohtani, M. et al, Amino Acid Mixture Improves Training Efficiency in Athletes. J. Nutr. 2006 A study of rugby players demonstrating the beneficial effects of the unique combination of leucine, isoleucine, valin, arginine and glutamine on the oxygen-carrying capacity of the blood, muscle function, fatigue, and recovery after heavy exercising. POSITIVE IMPACT OF BRANCHED CHAIN AMINO ACIDS ON MUSCLE SORENESS, FATIGUE AND RECOVERY AFTER EXERCISE Shimomura Y et al, Nutraceutical effects of branched-chain amino acids on skeletal muscle. J Nutr. 2006. Detailed biochemical discussion of BCAAs in muscle examining protein synthesis and muscle growth. Also, study involving humans doing squats demonstrating that BCAA supplementation decreased muscle soreness and fatigue even a few days after exercise. HOW MUSCLE DAMAGE AND FATIGUE IS PREVENTED BY AMINO ACIDS IN REPEAT EXERCISE Skillen RA et al, Effects of an amino acid carbohydrate drink on exercise performance after consecutive-day exercise bouts. Int J Sport Nutr Exerc Metab. 2008. A study of 12 cyclists and a detailed biochemical discussion of how the addition of amino acids to a carbohydrate drink improved performance, prevented damage and decreased fatigue after consecutive-day exercise. HOW AMINO ACIDS DURING EXERCISE AND AT REST ARE IMPORTANT FOR METABOLISM IN MUSCLES Wagenmakers AJ., Muscle Amino Acid Metabolism at Rest and During Exercise: Role in Human Physiology and Metabolism.1998 Highly detailed biochemical discussion illuminating the proposed and established processes of amino acids in exercise and at rest as a result of metabolism. The molecular by-products and chemical interrelationships that result from amino acid metabolism during exercise are also discussed.
