Water deficit after training in judo athletes submitted to different training intensities with and without hydration

The electrolytic balance is an important condition in the maintenance of homeostasis during exercise; however in practice of judo is not commonly occurs regular breaks during practice to occur rehydration. Therefore, in this study, we proposed to check the water deficit (DH) after training in judo underwent three training intensities with and without hydration during training and further analyze the effectiveness of a specific rehydration. The study included 14 athletes with a mean of 22.8 (+/- 4.58) years. Initially, it was conducted a physical examination and a test of specific capacity of modality for athletes to group together according to the physical and technical capabilities. Then the application of training protocols was done. The athletes had a BMI of 2.9 (+/- 2.64) kg/m(2) a fat percentage of 14.5% (+/- 6.92) and a HRmax of 198.2 (+/- 3.29) BPM. The mean values of DH post workout without rehydration, were 1,1L/h; 1.2 L/h and 1.6 L/h, the intensities, moderate and high, respectively. The values of DH medium with rehydration were proposed: 0.4 L/h; 0.3 L/h and 0.4 L/h and also the respective intensities. Significant difference when comparing the DH in both situations (p<0.05). In conclusion, the protocol used proven effective rehydration, since the athletes had a water loss after less than 1% practice.
