Salt Intake for Sports Women
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.3 Vol.3】
To investigate proper sodium intake for sports women, dietary sodium intake and urinary excretion were studied in students of physical exercise course. Sweat volume and sodium in perspiration under training were determined.
1) Sodium intake of physical exercise group was significantly larger than that of the reference group. But on urinary excretion, there was no remarkable difference.
2) The average perspiration volume of the group under 4 hours training was 1,937ml, and the total loss of sodium was suggested nearly 2,240mg (5.7g NaCl).
3) Sodium intake was strongly related to nutrition intake.
4) Proper standard of salt intake for the sports women will have to be considered in relation to nutrition intake. And further research about the sodium loss due to perspiration will be required.
