The purpose of this study was to investigate the effect of high fluid intake for the prevention of march-induced proteinuria and haematuria. Thirty-six male soldiers participated in two 25 km marches in a comfortable environment (outside temperature 13degreesC, cloudy weather), achieving a moderate average marching time of 3.5 h. Fluid intake during march 1 was not restricted (= habitual intake), whereas during march 2, the participants were asked to achieve a fluid intake of 1 L before and 2 L during the march. Urinary excretion of protein and albumin, haematuria, and various serum parameters were assessed before, during and after both marches. Unexpectedly, urinary albumin and protein excretion was higher during march 2 (with a high fluid intake), whereas haematuria was unaffected. The haemoconcentration, as judged from haemoglobin levels, was more intense in group 1 (with usual fluid intake) in accordance with the higher decrease of bodyweight during the march, and probably accounted for most of the serum creatinine concentration increases observed. A standardized (high) fluid intake of 2.5 L before and during a moderate exercise failed to confer any prevention against mild exercise-induced renal abnormalities.
