Abstract
Consumption of fruits high in anthocyanins, such as wild blueberries (WB)s, have been shown to influence lipolytic enzymes and increase fatty acid (FA) oxidation during rest. Purpose: Examine the effect of a WB drink on FA oxidation during moderate intensity exercise. Methods: Eleven aerobically trained males (26 ± 7.5 years, 74.9 ± 7.54 kg, 10.5 ± 3.2% body fat) completed an incremental cycling test to determine VO2peak (55.1 ± 7.5 ml/kg/min) followed by a washout diet avoiding foods high in anthocyanins. After two weeks, subjects completed a control cycling protocol at 65% of VO2peak for 40 minutes. Next, subjects consumed 375 g anthocyanins from WB powder for two weeks, and repeated the exercise protocol. Results: The WB trials increased FA oxidation by 19.7 (P = 0.049), 43.2 (P = 0.010), 31.1% (P = 0.012) at 20, 30 and 40 minutes, respectively. Carbohydrate oxidation rates were significantly lower by 10.1 (P = 0.024), 19.2 (P = 0.014) and 14.8% (P = 0.045) at 20, 30 and 40 minutes respectively, in the WB trials. Lactate was significantly lower at 20 (P = 0.005), 30 (P = 0.005) and 40 (P = 0.013) minutes in WB trial. Conclusion: Fourteen-day intake of WBs increased FA oxidation while decreasing carbohydrate reliance and lactate production during submaximal intensity exercise.
