Question

Quizplus · Accepted Answer

To maintain his body weight while in training and during a race, Lance needs to consume a significant amount of calories to compensate for the energy expended during his aerobic training. For someone weighing 80 kg and training aerobically for at least 90 minutes daily, a rough estimate of daily caloric needs including basal metabolic rate (BMR) and the calories burned during exercise would be around 4000 kilocalories. This accounts for his BMR (which can be roughly estimated at around 2000 kilocalories for an active male of his weight) plus the additional calories burned during his intensive training sessions.
