Higher levels of physical activity requires increased fluid intake due to increased water losses via sweating. PURPOSE: To determine the effect of physical activity on hydration status and water intake. METHODS: This study involved 8 visits to the Human Performance Laboratory over 22 days. Body weight and urine measurements were taken every visit. Physical activity was assessed by the International Physical Activity Questionnaire (IPAQ), water intake by the Water Frequency Questionnaire (WFQ), and hydration status by urine osmolality (UOsm), urine specific gravity (USG), and urine color (UC). From the IPAQ subjects were classified as low, moderate and high physical activity …
