Abstract

The purpose of this study was to evaluate the effect of glycerol supplementation on aerobic and anaerobicexercise performance in sedentary subjects and athletes. The glycerol supplement treatments were as follows: 40volunteers were selected and divided into two groups, sedentary and exercise groups. These two groups were furthersubdivided into two groups. The first group, the placebo (S), only consumed water; the second group (GS) consumedglycerol followed by water. Neither of these groups did any exercise for 20 days. The third and fourth groups consistedof the exercise group subjects; they were required to perform a 20-m shuttle run test every day for 20 days. The thirdgroup’s subjects, the placebo (E), only consumed water. The last group (GE) consumed glycerol followed by water. TheAstrand Cycle Ergometer Test (ACET) was performed, and the Cosmed K4b2 portable gas analysis system was used todetermine the aerobic capacity, while the Wingate Anaerobic Power Test (WAPT) was performed to determine the levelof anaerobic power. The 20 Meter Shuttle Run Test (20MSRT) was performed after glycerol supplementationthroughout the 20 days, and the exercise periods and distances were recorded.The glycerol supplement was found to have an increasing effect on aerobic and anaerobic performance in GS, Eand GE. A similar effect was found for the covered distances and time in the same groups. However, an adverse effectwas found on body weight.
