Effects of an isotonic beverage on autonomic regulation during and after exercise

Conclusions

We concluded that regardless of hydration status, the exercise protocol caused alterations in cardiac autonomic modulation, characterized by increased sympathetic and decreased parasympathetic activity. Although the isotonic solution administered (Gatorade, Brazil), containing carbohydrates (30 g), sodium (225 mg), chloride (210 mg) and potassium (60 mg) per 500 ml of the drink, generally produced lower alterations in HRV indices during exercise, it was not enough to significantly influence the changes in cardiac autonomic modulation. Throughout the recovery period, the hydration exercise protocol induced significant changes in cardiac autonomic modulation, promoting faster recovery of HRV indices, analyzed in the time and frequency domain.

Interesting, but I think a better protocol for the experiment would have been to add a category for drinking plain water for a third group, drinking at the same time the Gatorade group drank.

Alex, I think you're doing a great job by finding all these articles AND adding the conclusions for those of us who aren't able to read the whole article. Just thought to let you know!

Thanks Corina.
