Question

multiple choice question
carbohydrate loading has been found to ______ performance in single, high-intensity exercise tasks ranging up to one hour.

○ have little effect on
○ decrease
○ enhance

Explanation:

Carbohydrate loading is a strategy to increase glycogen stores. For single, high - intensity exercise up to an hour, research shows it has little effect on performance (longer - duration endurance activities are where it's more beneficial for enhancement). Decreasing performance goes against the purpose of carbohydrate loading. Enhancement is more for longer endurance, not short high - intensity up to an hour. So the correct option is the one stating it has little effect.

Answer:

A. have little effect on
