“The volunteers accomplished … a 30-minute treadmill exercise adopted by three totally different five-minute lifting, dexterity and sledgehammer swinging actions. After 45 minutes of train, the volunteers rested for quarter-hour … whereas ingesting 16 ounces of both a high-fructose, caffeinated gentle drink or water.
After the break, they repeated the cycle three extra instances for a complete of 4 hours. Earlier than leaving the laboratory, the volunteers got extra of their assigned beverage to drink earlier than consuming any additional fluids. The amount was both 1 liter or a quantity equal to 115 p.c of their physique weight misplaced by means of sweating, if that quantity was larger.”
Core physique temperature, coronary heart fee, blood strain, physique weight and markers of kidney harm have been measured earlier than train, instantly after and 24 hours later. Seven days later, the volunteers — which have been a mean age of 24 — underwent the identical trial once more, however switched teams, so those that obtained soda the primary time now obtained water, and vice-versa.
When volunteers drank soda, 75% of them had elevated ranges of creatinine of their blood, a marker for kidney harm. Solely 8% of contributors within the water trial had elevated creatinine. When ingesting soda, volunteers additionally had:
