This study was carried out to compare the nutrient intake, urinary excretion of mineral (Na, K, Ca, Mg, Zn, Fe, Cu), and the ratios of creatinine (Cr), body mass index (BMI) and basal metabolic rate (BMR) to the amount of mineral in 24-hour urine between both the male university students with few exercise (non-exercisers) and male university distance runners. The propriety of ratios of Cr, BMI and BMR was also examined in order to estimate intake of mineral for the male university distance runners. There were no significant differences in the intakes of energy, protein and carbohydrate between the both groups of subjects, and those major nutrients were at reasonable levels for the both groups of subjects. On the other hand, neither the intake levels of VB_6, Ca, Mg, and Cu in the non-exercisers, nor niacin, Mg and Cu in the male university distance runners reached the level of Recommended Dietary Allowance for the Japanese. The intakes of retinol, VB_1, VB_6 and Ca were higher in the male university distance runners than in the non-exercisers. The urinary excretion and excretion ratio to intake of Zn, excretion ratio of Na, ratios of Cr, BMI and BMR of Zn, and Cr ratio of Na were higher in the non-exercisers than those in the male university distance runners. So as to achive the same levels of Cr ratios of Ca and Zn as the non-exercisers, the male university long distance runners should take larger amounts of those minerals than the non-exercisers. It was suggested that the ratio of BMR rather than that of Cr ratio to urinary excretion of mineral would be suitable for the estimation of a desirable intake level of mineral for the male university distance runners.
