Dextrose 10 drink is superior to sodium-dextrose drink in increasing blood glucose and sprint speed in soccer players: A double-blinded randomized crossover trial study

摘要

Objectives. - This study aimed to examine the effect of dextrose drink (D) on blood glucose, VO2max, and sprint speed compared with Sodium-Dextrose drink. Equipment and Methods: We conducted a double-blinded crossover study of 22 young male (19 +/- 1.1 years) soccer players, consumed either Dextrose drink or Sodium-Dextrose drink. We compared pre- and post-data of Blood Glucose, VO(2)max, and sprint speed between the dextrose and sodium-dextrose drinks groups. The primary outcome was differences in Delta Blood Glucose between D and Sodium-D group. Secondary outcomes were differences in Delta VO(2)max and Delta sprint speed between D and Sodium-D group. Results. - The mean BG level was higher in D compared with Sodium-D group [136 +/- 22.9 mg/dl vs. 118 +/- 21.5 mg/dl] (P = 0.009). Mean differences of Delta BG of D (mean before and mean after) compared with Delta BG Sodium-D (mean before and mean after) is 16.8 mg/dl (P = 0.001). The mean of sprint speed is faster in the D group [15.2 +/- 1.25 sec vs. 15.9 +/- 1.61 sec] (P = 0.019), but we found no significant differences in VO(2)max between both groups [42.1 +/- 3.44 ml/min/kg vs. 42.3 +/- 3.98 ml/min/kg] (P = 0.834). Conclusion. - The present study demonstrated that dextrose drink without added sodium has a large influence on increasing blood glucose level and sprint speed. (C) 2021 Elsevier Masson SAS.
