Researchers found that during recovery periods between periods of exercise, it didn't matter what food was eaten.

 

Performance remained the same after resting for several hours, while levels of glycogen - used by muscles as 'fuel' - were actually slightly higher after fast food was eaten as a recovery food.

 

The research, published in the International Journal of Sport Nutrition and Exercise Metabolism¹, was led by University of Montana graduate student Michael Cramer.

 

In the study, 11 male athletes were asked to fast for 12 hours, before a 90-minute endurance² workout.

 

After this, half were fed hot cakes, hash browns and orange juice, followed by a burger, fries and a Coke two hours later.

 

However, the researchers said that the experiment included a fairly small sample, and the long-term effects on workout recovery of eating fast food over other, healthier sources of food are not known.
