“…Then, there were the inspection of nutritional biochemical indicators: in the early morning of the diet survey, venous blood was drawn from athletes before breakfast, and blood routine, serum total protein, serum albumin, serum globulin, ferritin, and other indicators were tested. Among them, we used flow cytometry to detect blood routine [ 25 ] (SYSMEX2100XE, 5 classification), biuret method to detect total protein (Olympus AU2700, Japan), and bromocresol green to detect serum albumin [ 26 ] (Olympus AU2700, Japan), using immunochemiluminescence method to detect serum ferritin (Beckmen automatic immunochemiluminescence instrument, USA).…”
