Protein addition to sport drinks not advantageousAdding protein to sport drinks is not beneficial in any way, as per findings from researchers at the McMaster University.

It was highlighted through the findings that protein addition to a carbohydrate-electrolyte sports drink did not enhance cycling time trial performance when compared with the drink alone. It was suggested that the reason why sport drinks are considered beneficial is because of carbohydrate content that provides the fuel for working body muscles and sodium that promotes maintenance of fluid balance.

From News-Medical.Net:

“Previous studies that suggested protein was beneficial used ‘ride to exhaustion’ tests that do not resemble normal athletic competition. In addition, the subjects in those studies received less than the optimal recommended amount of carbohydrate,” says Gibala. “Our study shows that protein confers no performance benefit during ‘real life’ exercise when athletes consume sufficient amounts of a sports drink.”

The study, which was funded by Gatorade, comes at a time when the sports drink industry is under pressure to create new products by adding ingredients that might further enhance performance. Some companies have heavily marketed protein-laced sports drinks as the next magic bullet, but Gibala’s research disputes such claims.

These findings were revealed by Martin Gibala, an Associate Professor of Kinesiology at McMaster, who remarked that there is nothing to suggest that athletes need protein during exercise sessions though a small amount of protein before exercises is good for repairing damaged muscles and promotion of training adaptations.
