Abstract
The purpose of this study was to investigate a manufacturer's claim that the Access Fat Conversion Activity Bar increases lipolysis and fat oxidation during prolonged exercise. Eight subjects completed two identical 120‐min bouts (58% of VO2Peak) after consuming either an Access bar or nothing. No significant difference between the two trials or trials x time were observed for the respiratory exchange ratio (RER) or plasma glycerol concentration (P > 0.05). Overall, the RER group mean value averaged 0.82 ±0.02 and 0.83 ±0.03 for the control and Access bar trials, respectively. The average group mean plasma glycerol concentration for the control and Access bar trials was 0.32 ±0.18 and 0.26 ± 0.07 mmol‐P1. Further, there were no differences between trials or trials x time for perceived exertion, blood glucose and lactate concentration. The Access bar was concluded not to influence lipolysis or fat oxidation during moderate intensity exercise.
