If a student frequently gets tired midway through aerobic fitness, what dietary change could they make?

Increasing the number of complex carbohydrates in a student's diet can significantly enhance their aerobic fitness performance. Complex carbohydrates are a key source of energy, providing sustained fuel for endurance activities like aerobic exercise. They are broken down slowly, leading to a gradual release of glucose into the bloodstream, which helps maintain energy levels over longer periods.

When engaging in aerobic activities, the body primarily relies on carbohydrates for fuel, especially during sustained exercise. If a student frequently experiences fatigue midway through their workouts, it may indicate that their energy reserves are being depleted too quickly, which can be addressed by consuming more complex carbohydrates such as whole grains, fruits, and vegetables. These foods not only provide energy but also contain essential nutrients and fiber, supporting overall health and performance.

In contrast, decreasing protein intake or increasing fatty foods may not provide the immediate energy boosts needed for aerobic activities and could hinder performance. Limiting hydration can lead to dehydration, further exacerbating feelings of tiredness and reducing physical capability during exercise. Therefore, adjusting dietary habits to include more complex carbohydrates is a practical strategy for improving endurance and overall fitness levels.
