Changes in hematological parameters of athletes after receiving daily doseof a mixture of 12 amino acids for one month during the middle and long-distance running training

Previous studies have shown that a mixture of amino acids, consisting of 9 essential amino acids and 3 nonessential amino acids was effective in facil itating muscle recovery from athletic activities. In this study, the object ive was to determine whether this amino acid mixture improved the physical condition and associated blood parameters of athletes in training when admi nistered for a prolonged period. Thirteen college middle- and long-distance runners were placed in a 6-month experiment and received the amino acid mi xture at the dose of 2.2 g/day for one month, 4.4 g/day for one month, and 6.6 g/day for one month with washout periods between test periods. The phys ical condition was scored and blood samples were collected before and after each test period. When the subjects received 2.2 g of the amino acid mixtu re three times a day, the physical condition was significantly improved alo ng with increases in red blood cell count, hemoglobin, hematocrit, serum al bumin, and fasting glucose, and a decrease in creatine phophokinase (p<0.05 ), suggesting increased hematopoiesis and glycogenesis, and rapid alleviati on of muscle inflammation by the amino acid mixture.
