ACUTE EFFECTS OF ENERGY DRINK INTAKE ON HYDRO-ELECTROLYTIC PARAMETERS DURING THE EXERCISE ON A TREADMILL

Listed in DataCite

ABSTRACT This work compares the effects promoted by energy drinks with diferente nutricional compositions on the hydro-electrolytic balance of resistance runners.

Description

Twelve men participated in this double blinded, randomized crossover study, ingesting 3mg*Kg-1 of a conventional energy drink with caffeine or sugar-free, and a placebo 40-minutes before tests on thermoneutral environment. The duration of the session was 60 minutes with constant intensity between 65 and 75% of VO2max, followed by a sprint corresponding to 100% of VO2max until exhaustion.

There were evaluated body weight (BW), absolute and relative dehydration, urine density, sweating rate and Na+, K+ and hematocrit levels. During the exercise, the participants drunk only water every 15 minutes. Changes in urine density levels were observed before and after exercise for all procedures (p <0.05).

There was no significant difference on the levels of Na+, K+ and hematocrit between the drinks (p> 0.05), remaining within normal levels. It is concluded that different types of energy drinks do not affect the hydro-electrolytic balance of resistance runners during the exercise.
