Urinary mineral excretions were measured on five healthy 19-years-old female students in domestic sciences course of a woman's college and five healthy 18-19-years-old female students in physical training course, during the training camp of ski events. The examination for the female students in domestic sciences course was done on 22 December as of ordinary time at school and on 23-25 December 1969 in training camp of ski event at a skiing ground. For the female students in physical training course the examination was done on 9-13 January 1970 in training camp at the same skiing ground and on 3-5 February 1970 in ordinary time at school. Every three hours urine was collected during the examination periods. (1) Whole urine volume per 24 hours decreased in training camp in comparison with that in ordinary school time, while the excretion increased after the physical exercise and decreased during the sleeping hours. (2) Creatinine excretion per 24 hours increased in the training camp and diurnally the excretion increased after the physical exercise. (3) Decrease of Na excretion and increase of K excretion were observed in the students of domestic sciences course in training camp. Increase pattern of Na and K excretion with diurnal variation in training camp was observed with physical exercises. (4) Urinary excretion of Ca and Mg increased by the female students of physical training course in training camp. On the diurnal pattern, the increase of Ca and Mg excretion caused by physical exercise showed some time lag of the peak compared to that of Na and K. (5) Phosphorus excretion increased both in the students of domestic sciences course and of physical training course in training camp. The decrease of P excretion in the daytime and the increase in the sleeping hours was commonly observed for both groups.
