Branched Chain Amino Acid Product Description Consumption of branched chain amino acids (BCAA) leucine, isoleucine, and valine before, during, and following endurance exercise has been demonstrated to prevent or decrease the net rate of protein degradation and stimulate recovery of muscle protein synthesis.
BCAA supplementation may reduce the muscle damage associated with endurance exercise. Supplementary BCAA have been shown to decrease serum concentrations of the intramuscular enzymes CK (creatine kinase) and LDH (lactate dehydrogenase) following prolonged exercise. These enzymes are used as clinical markers of muscle fiber damage. Intense training can also impair immune system function, often leading to increased risk of illness/infection following periods of high intensity, long duration exercise. (BCAA) supplementation has been shown to recover the ability of immune cells to mobilize in response to infection after a long distance intense exercise.
Additionally, the BCAA leucine, serves as an important signal on it’s own to enhance or amplify protein synthesis, following both endurance and strength training. Studies feeding BCAA soon after exercise suggest that post-exercise consumption of amino acids stimulates recovery of muscle protein synthesis. In fact BCAA, when added to protein supplementation, has been shown to have a enhanced effect on the stimulation of protein synthesis immediately following resistance/strength training.
Consumption of BCAA before or during endurance exercise may prevent or decrease the net rate of protein degradation, may improve both mental and physical performance and may have a sparing effect on muscle glycogen degradation and depletion of muscle glycogen stores
Furthermore, BCAA supplementation in combination with moderate energy restriction has been shown to induce significant and preferential losses of visceral adipose tissue and to allow maintenance of a high level of performance. The recommended dietary intake of BCAA’s is a minimum of 7 g/day for sedentary individuals (150lb individual), and more for those participating in intensive training in order to optimize rates of whole body protein synthesis.
