1. Out of the three time points, Max was the most dehydrated immediately after exercise.
2. The two parameters that can be used to determine Max’s hydration status is color and and pH. It is not specific gravity (SG) because Max’s SG is 1.035 which is within normal range. It is also not protein because in the lab manual it says that a trace amount of albumin in Max’s urine is normal.
3. If ADH levels increase, water reabsorption by the DCT/collecting ducts increases and the resulting urine excreted is concentrated.
4. Max’s ADH levels are the highest immediately after exercise. The reason for this is because the color of his urine is dark yellow. According to the lab manual, concentrated urine can be observed with a darker
