Exercise is a stimulus for Anti-diuretic hormone (ADH)secretion. Osmoreceptors detect the increase in blood concentration (decreased dilution of blood due to water loss). This information is then integrated in the hypothalamus which then stimulates the posterior pituitary via nerve signals to release ADH. ADH works on the kidneys, making them reasborb and conserve water - this decreases the volume of urine produced. A small volume of concentrated urine is produced - a sign of dehydration - which is why its important to keep hydrated and drink lots of water after exercising.

When we sweat we compensate by making a smaller volume of urine. The urine appears darker in color because it is more concentrated.

I guess that's why we have to drink water, otherwise we'll be dehydrated.
