Which type of carbohydrate is more beneficial immediately before a high-intensity workout?

Simple sugars are particularly beneficial immediately before a high-intensity workout because they are rapidly digested and absorbed into the bloodstream, leading to a quick increase in blood glucose levels. This fast-acting source of energy is crucial during high-intensity exercise, where the body relies on readily available glucose to support performance.

Complex carbohydrates, while they provide longer-lasting energy due to their gradual digestion, may not offer the immediate boost needed right before intense activity. This slower release can lead to delayed energy availability, which is not optimal when quick bursts of power and speed are required.

Fiber-rich carbohydrates and whole grains, although nutritious and part of a well-rounded diet, can also slow digestion due to their higher fiber content. This can result in potential discomfort during exercise, making them less suitable for consumption immediately before a workout where quick energy is desired.

Therefore, simple sugars serve as the most effective choice for athletes looking to maximize their performance in a high-intensity workout scenario due to their quick energy-release properties.
