Source text - English Adding protein probably won't make you run faster or work out harder. But, some researchers say, it can be beneficial after exercise to help your muscles recover.
"Certain kinds of protein stimulate insulin release, which is important for muscle glycogen replacement" following exercise, said Martin Gibala, lead author and associate professor of kinesiology at McMaster University in Canada. But ingesting protein during activity doesn't appear to have the same effect, he said.
The current analysis consisted of a double-blind study of 10 experienced cyclists who rode in three 80-kilometer time trials on stationary bikes. In separate tests, the athletes were given a drink with 6% carbohydrate (as in traditional sports drinks), 6% carbohydrate and 2% protein, and an Aspartame-sweetened placebo drink providing no energy.
The carbohydrate-enhanced drink did improve performance over the placebo, but the addition of protein had no measurable effect. Athletes logged the slowest times when drinking the placebo.
Protein may not as easily be absorbed during exercise as carbohydrates, according to Dr. William O. Roberts, associate professor of family medicine at the University of Minnesota, and past president of the American College of Sports Medicine.

“Certos tipos de proteína estimulam a libertação de insulina, o qual é importante para repor o glicogénio no músculo” depois do exercício, disse Martin Gibala, autor principal e Professor Associado de Cinesiologia na Universidade McMaster no Canadá. Contudo, segundo ele, a ingestão de proteína durante a actividade não parece ter o mesmo efeito.
A actual análise consistiu num estudo duplamente cego de 10 ciclistas experientes que percorreram 80kms em três testes cronometrados em bicicletas estacionárias. Em testes separados, foi dado aos atletas uma bebida com 6% de hidratos de carbono (tal como nas bebidas desportivas comuns), 6% de hidratos de carbono mais 2% proteína e uma bebida placebo adocicada com Aspartamo que não proporciona energia.
A bebida enriquecida com hidratos de carbono melhorou o desempenho comparado com o placebo, mas a adição da proteína não teve nenhum efeito mensurável. Os atletas obtiveram os resultados mais baixos quando beberam o placebo.
Ao contrário dos hidratos de carbono, a proteína poderá não ser facilmente absorvida durante o exercício, de acordo com a opinião de Dr. William O. Roberts, Professor Associado de Medicina Familiar na Universidade de Minnesota e antigo presidente do Colégio Americano de Medicina do Desporto.
