In order to study the response of plasma trace minerals during exercise in cold water at varying temperatures, three groups of ten male Wistar rats each were forced to swim until exhaustion in water at different constant temperatures (10, 20 and 32 degrees C), while another 3 groups were kept at rest in water at the same temperatures and another group at rest out of the water, at room temperature (21 degrees C). Rectal temperature (RT) was measured before and after the exercise. Samples of arterial blood were obtained under anaesthesia (pentobarbital) from the abdominal aorta after the exercise, and serum concentrations of Cu, Zn, Mg and Ca were determined by flame atomic absorption spectrophotometry (FAAS). The swimming time (ST) decreased in cold water, the values obtained at 10 and 20 degrees C being 3.3% and 8.5%, respectively, of those observed at 32 degrees C. The RT of the animals swimming at 32 degrees C was 32.5 +/- 1.8 degrees C (mean +/- SD) and fell to 25.0 +/- 2.0 and to 19.1 +/- 1.5 degrees C in those swimming, respectively, at 20 and 10 degrees C. The concentrations of Mg, Cu and Ca were significantly higher (+50%, +36% and +7%, respectively) in animals subjected to exercise with respect to the control groups in water, although there were no differences among the three groups. On the contrary, Zn rose progressively with the increase of WT (+32% at 10 degrees C, +60% at 20 degrees C and +76% at 32 degrees C).(ABSTRACT TRUNCATED AT 250 WORDS) |
