Estimate the RER in different conditions.  On the graph below, you will find three lines that show how RER will change with increasing intensity during a maximal exercise test in the following conditions.     1. Which color represents the line, if an athlete begins the test in the morning after an overnight fast ? 2. Which color represents the line, if the athlete has eaten scrambled eggs and coffee for breakfast one hour before the test ? 3. Which color represents the line, if the athlete has eaten pancakes, strawberries, and orange juice one hour before the test ?
