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.
研究了含有异麦芽酮糖醇的替代糖，以证实以下假设：摄入异麦芽酮糖醇会影响耐力，因为其在肠道中的水解和吸收速度较慢。对照组的游泳时间有下降趋势，但摄入低血糖指数（GI）甜味剂的组则呈逐渐上升趋势。含有异麦芽酮糖醇的低聚果糖（FOS）和转化糖（IS）组，与对照组相比，血糖和乳酸水平的变化有显著差异（p<0.05）。PAL100组的血清肌酸磷酸激酶（CPK）和血清乳酸脱氢酶（LDH）显著低于对照组（p<0.05）。与对照组和PAL20（20%异麦芽酮糖醇）组相比，IS组的谷胱甘肽过氧化物酶（GSH-Px）有显著差异（p<0.05）。摄入FOS似乎能提高耐力，因为基于异麦芽酮糖醇的糖浆中的果糖和FOS吸收速率和GI水平较低。实际应用：糖是运动的主要能量来源，但由于甜味持续时间短，会导致过量摄入，进而引发肥胖、糖尿病和皮肤老化等疾病。发现含有异麦芽酮糖醇的替代糖复合物可作为运动表现的糖替代品。运动表现不仅仅适用于运动员或活跃人群。一般来说，肌肉量低的老年人活动能力也低。替代糖可以是很好的补充剂来源，有助于他们在摄入量较少的情况下顺利活动。因此，对替代糖进行耐力测试对能量补充剂行业来说是一项重要研究。
