Carbohydrate consumption is particularly important during endurance training lasting 45 minutes or longer because these activities rely heavily on glycogen stores for energy. As the body engages in prolonged exercise, especially at moderate to high intensities, the demand for quick energy increases, and carbohydrates serve as the primary fuel source.

When engaging in endurance activities, the body can deplete its glycogen reserves, which are stored primarily in muscles and the liver. If glycogen stores are not replenished, performance can diminish significantly, leading to fatigue and reduced exercise capacity. Therefore, consuming carbohydrates during such endurance events can help maintain energy levels, enhance performance, and delay fatigue.

High-intensity interval training also benefits from carbohydrate intake, but the need is less critical in lower duration activities compared to extended endurance training where glycogen depletion is more pronounced. Strength training involves shorter bursts of effort and can utilize different energy systems, making carbohydrate needs less critical. Static stretching does not significantly require carbohydrate fuels since it does not demand high energy expenditure, thus making the carbohydrate intake less relevant in that context.
