Endurance athletes needs protein + carbohydrates during exercise

Here is one for the endurance athletes out there. Traditionally endurance athletes have focused on consuming carbohydrate only sports supplements during their training. It seems to make sense that a sport were the bodies stores of carbohydrate are used that drinking carbohydrates will boost performance. The above study shows that a protein plus carbohydrate drink during exercise is more beneficial than a carbohydrate alone drink. The athletes involved reported lower fatigue levels and showed an increase fat oxidation. They also showed to maintain better time trial times and power output compared to the carbohydrate only group.
I feel a 2/1-3/1 ration carbohydrate/protein would be the most beneficial for athletes looking to increase performance during exercise.
