We will be comparing urine output, urine osmolarity, urine pH, and presence of urinary glucose between subjects that have ingested water ad libidum, water at 7.5 mL/kg body weight, water at 16 mL/kg, cola at 7.5 mL/kg, sports drink at 7.5 mL/kg, and diet cola at 7.5 mL/kg body weight. 1. Which of these groups would you expect to have the highest urine output? Why? 2. Which of these groups would you expect to have the highest urine osmolarity? Why? 3. Do you expect to see any alteration in urinary pH in any of the groups? Why or why not? 4. Would you expect to see the presence of glucose in the urine for any of these groups? Why or why not?
