SIQUEIRA, Luciano de Oliveira et al. Analysis of carbohydrate supplementation and isotonic solution hematological and biochemical parameters on professional soccer players in real training. Rev. Bras. Ciênc. Esporte [online]. 2012, vol.34, n.4, pp.999-1016. ISSN 0101-3289.  http://dx.doi.org/10.1590/S0101-32892012000400014.

The aim of this study was evaluate the effect of supplementation with carbohydrate sports drinks and laboratory parameters in athletes on the football field, in a real training. 10 ml of venous blood and 50 ml of urine were collected at rest and 15 minutes after training. The results show that intense exercise caused a variable degree of urinary stasis and electrolyte changes caused by a marked decrease in serum sodium, potassium, magnesium, phosphorus and glucose (p <0.05), which was not modified by any type of supplementation protocol under the conditions proposed in this study. The proposed electrolyte supplementation was shown to be limited to prevent electrolyte variations and that the recovery must be evaluated in light of an environmental and training context.

Palavras-chave : Electrolytes; water-electrolyte balance; dehydration; dietary supplements.
