Hydration status and performance comparation through of rehydration with sports drink and flavor water during kangoo jump class

Abstract

Kangoo Jump is a gymnastics modality with moderate volume that can cause loss of fluids and the need to replace them. The aim of this study was to compare parameters of hydration and performance after rehydration with sports drink or water during a Kangoo Jump class. Materials and Methods: 12 female volunteers, experienced Kangoo practitioners participated. Four sessions were conducted throughout the study. In the first visit the body composition evaluation and an anamnesis was applied. In the second visit, a Kangoo class was performed without hydration and, in the 3rd and 4th visits, the experimental classes (with the replacement of sports drink or water) were evaluated. Hydration parameters (Sweat rate, % hydration, sweat volume, color and specific gravity of urine, subjective sensation of thirst and heat) and performance parameters (HR, Borg, auricular temperature). The statistical package SPSS 23.0 was used and a significance level of p<0.05 was used: The dehydration level was lower in the rehydration sessions (p = 0.003), but there was no difference between beverage types (p = 0.241). The heart rate was higher in the dehydration session compared to the rehydration sessions (p = 0.030), but no difference between the beverage types (p = 0.435). The auricular temperature was not different between the sessions (p = 0.859), nor did it change during the classes (p = 0.201). Conclusion: A Kangoo Jump class causes dehydration and rehydration strategies are necessary, however both water and sports drinks are sufficient for adequate rehydration.
