Fuente: WIPO "tomato" The present invention is a method to improve physical-sports performance, reduce fatigue, combat physical-sports aging, and to cure and prevent physical injuries, based on an effective dose of glycine, L-proline, L-lysine, L-aspartic acid (or L-aspartate, citric acid, or citrate), and vitamin C. The method is based on the limitations and subsequent conditions of the metabolism in three aspects: (1) the synthesis of ATP in mitochondria, dependent on the Krebs cycle; (2) the synthesis of proteins of the passive mechanical system (collagen and elastin); (3) the mechanism of muscle contraction in actin-myosin interaction cross-bridge cycles. while ensuring that the diet must contain a sufficient amount of protein.
