Isoenergetic drinks intake effects during swimming training

Abstract

The purpose of this study was to verify the influence of the isoenergetic drinks intake on the athletes performance during a high intensity swimming interval training session. The sample embraced six 15-20-year-old male athletes. They performed three training sessions, one with no liquid intake, a second one with Marathon intake, and a third one ingesting placebo. The training session was performed in a 10 x 100 meters series with maximum intensity and a four-minute interval between each series. The following variables were analyzed: body weight, heart rate, blood glucose level, and swimming time. The results showed significant differences in favor of the treatment with Marathon concerning the glucose level variable. The heart rate was significantly higher during the training session. The weight loss with no liquid intake was significantly higher when compared to the other treatments.
