Question

Quizplus · Accepted Answer

For an individual weighing 80 kg and engaging in significant aerobic activity such as training for a marathon bicycle race, the caloric needs are substantially higher than those of a sedentary person. The basal metabolic rate (BMR) for a man of this weight is roughly 2000 kcal/day. Aerobic exercise, especially at the intensity and duration described (at least 90 minutes daily), can easily require an additional 2000 kcal or more, depending on the intensity of the workout. Therefore, a total daily intake of at least 4000 kcal is a reasonable estimate to maintain body weight during intense training periods.
