Abstract

GODOIS, Allan da Mata et al. Water loss and hydration practices in soccer players. Rev Bras Med Esporte [online]. 2014, vol.20, n.1, pp.47-50. ISSN 1517-8692.  https://doi.org/10.1590/S1517-86922014000100009.

INTRODUCTION:

Football players are subjected to great physiological stress during training. The characteristics of the activity, associated with unfavorable climatic conditions, can lead to intense dehydration resulting in a reduction in physical performance.

OBJECTIVE:

To estimate the percentage of dehydration in professional soccer players during training sessions in Cuiabá-MT, Brasil.

METHODS:

Data were collected in the team's training facility. The study included 17 male professional athletes (age = 21.53 ± 1.19 years; weight = 71.99 ± 7.66kg; stature = 1.76 ± 0.08m, BMI = 23.31 ± 1.69kg/m²). The pre- and post-training weighing in two non-consecutive days training (A and B) were obtained, and through the weight loss verified, we obtained the difference in body mass (ΔBM) and also noted all fluid intake. The recorded data were applied to the specific formulas for analysis.

RESULTS:

The ΔBM between the initial and final measurements was 1.08 ± 0.45kg in the training A, and training B was 0.85 ± 0.47kg, representing dehydration of 1.5 ± 0.63% and 1.19 ± 0.59%, respectively. The volume of fluid intake was 2,591 ± 440mL in the training A, and 926 ± 356mL in training B. The soccer practice reduced the body mass of athletes after training, indicating that there was dehydration.

CONCLUSION:

Despite the constant supply of water to the players, we found that ad libitum fluid replacement was not sufficient to maintain the hydration status of all athletes.
