The Effect of Oral Ingestion of Drinks Containing Either Fructose or Glucose on Post-Exercise Hypotension
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.39 Vol.39】
ABSTRACT
The aim of present study was to examine the effects of ingestion of either glucose or fructose beverage following moderate bicycle exercise on central and peripheral hemodynamic responses. Seven healthy male subjects ingested orally 350 cc drink containing either glucose (G trial), fructose (F trial), or water (C trial) as a control, just15min after the cessation of 30 min exercise at 65% of VO₂max and kept rest for 2 hours. During the protocols, heart rate (HR), mean blood pressure (MAP), the blood flow (BF) and its vascular conductance (VC) in superior mesenteric (SMA) and femoral artery (FA) were measured. In the G trial, MAP was significantly decreased against prior-exercise baseline value, but not changed in the F trial. VCSMA were significantly greater for G trial than those for F and C trials at 30 and 60 min after ingestion of drink. Our results suggest that the ingestion of fructose beverages after exercise blunted the post-exercise hypotension due to insufficient visceral vascular vasodilation.
