The latest research from the University at Buffalo in New York finds that drinking soda after exercise can cause dehydration and affect the kidney function.
For the study, 12 healthy and physically fit adults whose average age was 24 years were recruited by the scientists. The participants completed 30 minutes on the treadmill. After the exercise, they were completing tasks that mimicked the physical work on an agriculture site.
After physical activity of this kind, all of them relaxed for 15 minutes and received either high-fructose caffeinated soft drink or water. The researchers measured heart rate, body temperature, body weight, and pressure before, immediately after, and hours after the session of physical activity.
Analysis of the received data showed that participants who drank soft drinks were mildly dehydrated and had higher levels of vasopressin, a hormone that increases the blood pressure.
