Maple syrup (MAP) is derived from the inspissation of acer saccharum sap, and this main material is composed as a sucrose-like carbohydrate (CHO). This food substance has metabolic effects on mammalian cells and some animal models. We hypothesized MAP ingestion would enable athletes to carry out endurance exercise without inhibiting fat oxidation. Here we investigate the effect of MAP ingestion on fat oxidation during incremental exercise on a cycle ergometer in endurance athletes (n=10) who exercised after ingesting MAP or sucrose (SUC). We measured fat and CHO oxidation, blood glucose concentration, and blood lactate concentration of subjects during incremental exercise. Between MAP and SUC groups, average fat and CHO oxidation was significantly different (p<0.01 and p<0.001, respectively). Blood lactate concentrations in the MAP group were significantly lower than in the SUC group, -5, 0 min (p<0.05). In addition, blood glucose concentration in the SUC group at 24 min was significantly lower than at -5 min (p<0.05). Our results indicated that MAP ingestion promoted only slight fat oxidation and a slow increase in blood lactate concentration compared with sucrose ingestion.
