Description
Summary:It is well established that carbohydrate solutions can improve the performance in prolonged exercise. The aim of this study was to compare the impact of sugar and glucose solutions on exercise performance of swimmers. Twelve male teenager elite Iranian swimmers aged 12-17 years from Waterpolo Team of Ahvaz Oil Industry participated in a double-blind cross-over trial. They consumed three oral 6% purified carbohydrate solutions as glucose, sugar or placebo (aspartame) formulas in three non-consecutive days. In each day the swimmers undertook a 2×200-meter incremental swimming by 15 minutes time interval. Before starting the second course, subjects consumed their solutions. Blood glucose levels and time elapsed in two phases were recorded. Longer Swimming time significantly caused by sugar solution in the second course. Blood glucose level was increased by sugar and glucose solutions higher than the placebo before starting the second swim (p
