Your older sister is in training for a marathon (26 mile run), and she has been experiencing acute kidney dysfunction during some of her 15-20 mile training runs. She went to the doctor, and her laboratory tests showed elevated serum concentrations of K+, lowered serum concentrations of Na+, and a decrease in the GFR. Her doctor said she may be at risk of developing renal failure during her marathon race.

Explain why these symptoms and conditions may occur while running a marathon.
