AB  - BACKGROUND: Exercise training is known to increase fat utilization during 
      exercise. Diets containing antioxidants and branch chain amino acids (BCAAs) are 
      also reported to have potential effects on fat utilization. Cashew apple juice 
      (CAJ) comprises many nutritional components including vitamin C and BCAAs. This 
      study aimed to investigate the effect of CAJ supplementation on substrate 
      utilization during high-intensity exercise in trained and untrained subjects. 
      METHODS: Ten trained and ten untrained men were randomly supplemented with either 
      placebo (PLA) or CAJ at 3.5 ml/kg body mass (BM) /day for 4 weeks with a 4-week 
      washout between treatments in a randomized cross-over design. Before and after 
      the 4-week supplementations all subjects performed cycling exercise at 85% of 
      maximal oxygen consumption for 20 minutes. At rest, before, and immediately after 
      the exercise, venous blood samples were taken to determine glucose, insulin and 
      lipid concentrations. Expired air was collected during the 20 minutes of exercise 
      to calculate substrate utilization. RESULTS: During the exercise in both trained 
      and untrained groups, there were lower carbohydrate (CHO) and higher fat 
      oxidation rates and contributions to total energy expenditure after the CAJ 
      supplementation compared to the PLA supplementation (p<0.05). These values were 
      greater in the trained group than the untrained group except CHO oxidation rates 
      (p<0.05), which were not significantly different. Moreover, in both trained and 
      untrained groups, resting plasma vitamin C concentrations were significantly 
      higher after the CAJ supplementation compared to the PLA supplementation, without 
      any change after the PLA supplementation. These values were greater in the 
      trained group than the untrained group (p<0.05). There were no significant 
      differences in glucose, insulin or lipid concentrations between the groups' blood 
      samples. CONCLUSION: The findings of this study suggest that CAJ supplementation 
      enhanced fat oxidation during exercise may enhance endurance performance, but 
      specific studies are needed to assess this possibility.
