Abstract: This study assessed the effectiveness of three different sport drinks (PW, SP, GT), two brands of bottled coconut water (SX, CF) and one type of fresh coconut water (CC) as rehydration fluids, based on the electrolyte and sugar contents of the different samples. Furthermore, the differences between the production batches (L1 and L2) of the selected beverages were also analyzed. A Buck Scientific, 210 VGP, Atomic Absorption Spectrometer was used to measure the content of sodium, potassium, calcium and magnesium in all the samples. Chloride was quantified by the Mohr method and the sugar content by the Fehling test. All of the results showed excellent coefficients of determination, and statistical significance was found for the analyzed factors, meaning, beverages, batches and beverage-batch interaction. The sport drinks showed higher values than the coconut water regarding sodium content (55.81 mg/100 mL), but coconut water was much better in relation to the potassium (452.1 mg/100 mL), calcium (19.05 mg/100 mL), magnesium (19.49 mg/100 mL) and chloride (247.1 mg/100 mL) contents. Finally, there was no clear difference in the sugar content of commercial drinks and coconut water, because PW-L2 (6.68 g/100 mL) and fresh coconut water (6.33 g/100 mL) were statistically the same, which means that both beverages are effective as a source of carbohydrate recovery after exercise. Conclusively, coconut water is a good choice as natural sport beverage, although, it is recommended to compensate the sodium deficiency with a salt rich diet or by choosing the sodium richer variety and maturity stage of the coconut.
