- The graph shows changes in blood plasma glucose concentration before exercise, during exercise and during recovery with and without epinephrine (adrenaline) infusion. Epinephrine infusion was started 30 minutes into the exercise routine. [Graph displays plasma glucose levels over time with a spike following epinephrine infusion.]
