Professional athletes train for hours every day and their dietary needs far surpass those of the typical exerciser. They have higher protein needs and require carb levels that will give them both short bursts of energy and long levels for endurance.
Gatorade, the company most well known for hydration beverages, has created a line of product for professional athletes called Gatorade G Series Pro. This line was created with elite athletes in mind, those who train for hours and face different nutritional hurdles than the rest of us. This line has different nutritional standards than the other lines Gatorade offers, the traditional Gatorade often referred to as G or G2 (the lower sugar version), the G Series Fit and the G Series Natural. G Series Pro is offered in the same three step line as the G Series Fit, with Prime, Perform and Recover. Prime was created for use an hour before training, Perform during and Recover for use within two hours after a workout.
