Alternative sugars containing isomaltulose were investigated to confirm the hypothesis that isomaltulose ingestion affects endurance capacity due to slow rates of hydrolysis and absorption rate at the intestine. A swimming time of the control group tends to decrease, but the group administrated with low glycemic index (GI) sweeteners tend to increase gradually. Fructo‐oligosaccharide (FOS) and inverted sugar (IS), contained isomaltulose, groups showed a significant difference of change in blood glucose and lactic acid level than control group (p < .05). Serum creatine phosphokinase (CPK) and serum lactate dehydrogenases (LDH) of PAL100 were significantly lower than that of the control group (p < .05). IS showed a significant difference in glutathione peroxidase (GSH‐Px) compared to Con and PAL20 (20% isomaltulose) group (p < .05). Consuming FOS seems to increase an endurance capacity since fructose and FOS based in isomaltulose contained syrup showed low absorption rate and GI level. PRACTICAL APPLICATIONS: Sugar is a major energy source for exercise, but it causes excessive intake because of the short duration of sweetness, which causes diseases such as obesity, diabetes, and skin aging. An alternative sugar complex containing isomatulose was found to be a sugar substitute for athletic performance. Athletic performance is not just for athletes or active people. In general, elderly people with low muscle mass have low mobility. Alternative sugars can be a good source of supplements to help them perform smoothly with less intake. Therefore, an endurance test with alternative sugars is and important study for energy supplements industry.
