Pre-Workout Foods – Bananas

By Tom 0

Bananas are a great source of both carbohydrates and potassium. We require carbohydrates to fuel our muscles, to give us energy, especially when we’re working out. They’re accessible, tasty and nutritious. Due to their high potassium content, Bananas are fantastic for maintaining nerve and muscle function. The body doesn’t store too much potassium at a time so they’re a ideal source for a small hit, ready for your workout.

Furthermore, Bananas has a Glycaemic Index (GI) between 48 and 51, depending on how ripe they are. This means that they are a low GI food, resulting in a slower release of carbohydrates. We can also calculate the Glycaemic Load for a Banana which will indicate how much your blood sugar levels will actually rise.

The total amount carbohydrate in the average medium banana has approximately 27g. This will calculate the GL to be:

27 x 51 / 100 = 13.77

Best Consumed: In terms of the GL, this is seen as a medium impact and as such can be consumed no more than 30 minutes prior to exercise.

Tip: Add in 1/2 cup of Greek Yoghurt to increase your protein intake for the ultimate pre-workout snack.
