“…The multi-ingredient formula containing valine, isoleucine, leucine, β-alanine, creatine, l -carnitine, quercetin, and betaine was pre-mixed and then suspended in the 0.5% CMC-Na solution (CMC-Na: distilled water = 0.5:100, w / v ). The total daily dose of each component was 125 mg/kg, 125 mg/kg, 250 mg/kg, 182 mg/kg, 250 mg/kg, 200 mg/kg, 25 mg/kg, and 284 mg/kg body weight, corresponding to valine, isoleucine, leucine, β-alanine, creatine, l -carnitine, quercetin, and betaine, respectively, which was based on the available literature [ 4 , 10 , 11 , 12 , 13 , 14 , 15 ]. The formula was administrated twice a day at half the total daily dose via oral gavage at 8:00 am and 8:00 pm for 3 d and 7 d, respectively, after which an exhaustive treadmill test was performed to assess the acute effect of the formula on exercise performance, the volume of oral-gavage was 15 mL/kg body weight.…”
