• Monitor hydration

o Urine color: first morning urine is best indicator of hydration status. Dark colored urine (apple juice, ice tea) is sign of dehydration. Urine may change colors after taking vitamin supplement - not an indicator of hydration status.

o Body weight: monitoring weight after first urine is best time to monitor weight. May be less effective in females due to menstrual cycle.

o Sweat loss: measure body weight before and after exercise

• Fluid losses are increased by

o Air temperature

o Exercise intensity and duration

o Body size and gender (men)

o However, if you are more likely to drink more fluids due to taste of sports drink, that is better than nothing
