"What’s exciting about this comparison is that both of these products have been highly heralded and hyped in their respective arenas. Surge in its exact formulation doesn’t have any peer-reviewed research behind it. However, Berardi et al reported that a solution of similar construction to Surge (33% whey hydrolysate, 33% glucose and 33% maltodextrin) was slightly superior for glycogen resynthesis at 6 hrs postexercise compared to a 100% maltodextrin solution. Effects on muscle protein flux were not measured.
Chocolate milk has thus far had an impressive run in the research examining its applications to various sporting goals [2,3]. It has performed equally well for rehydration and glycogen resynthesis compared to carb-based sports drinks, and it has outperformed them (and soy-based drinks) for protecting and synthesizing muscle protein. A standout study in this area was a comparison of chocolate milk, Gatorade, and Endurox R4 (a sports drink with a 4:1 carb to protein ratio) . Chocolate milk was equally effective as Gatorade for total work output and prolonging time to exhaustion. Interestingly, both of the latter products outperformed Endurox R4 in both tests. The researchers speculated that the use of maltodextrin rather than sucrose (yes, you read that correctly) as the dominant carbohydrate source was the Achilles heel of Endurox R4. More on the virtues of sucrose instead of straight glucose for exercise applications will be covered."
