It is well documented that exercise-induced muscle damage (EIMD) decreases muscle function and causes soreness and discomfort. Branched-chain amino acid (BCAA) supplementation has been shown to increase protein synthesis and decrease muscle protein breakdown, however, the effects of BCAAs on recovery from damaging resistance training are unclear.

There is very little specific validated information available in relation to the human metabolic pathways of both amino acids and whole proteins in regard to NNU, gluconeogenesis, catabolism and effects upon body composition. The pathway of substrate metabolism often affects hormonal levels and responses in a cascade or matrix manner rather than a simple linear action/reaction scenario that is often assumed supplemental and pharmaceutical preparations.

Considerable debate has taken place over the safety and validity of increased protein intakes for both weight control and muscle synthesis. The advice to consume diets high in protein by some health professionals, media and popular diet books is given despite a lack of scientific data on the safety of increasing protein consumption. The key issues are the rate at which the gastrointestinal tract can absorb amino acids from dietary proteins (1.3 to 10 g/h) and the liver’s capacity to deaminate proteins and produce urea for excretion of excess nitrogen.
