Craig is a college junior who is on the college cross-country team. He has been training hard to make the top seven runners. He feels comfortable with his training plan but is confused about how to nourish his body to maximize his performance in daily practice runs, time trials, and competitions. He has found it difficult to eat enough throughout his busy school day and at the same time eat the
right foods that don't upset his stomach. Craig makes an appointment with a registered dietitian to learn what he can do to improve his competitive edge. In the first appointment with the dietitian Craig goes over his typical dietary intake for the week. He discovers that he is not eating enough before or after his workouts and that this is the likely reason he is not recovering between workouts. He also has his body fat and body water measured. The dietitian discovers that his body water is low, which means he is dehydrated, and that his body fat percentage is 2.5%. The dietitian encourages Craig to monitor his weight before and after his workouts to determine how much fluid he needs to replace. After his hour-long weekend training run Craig discovers that he lost 3 lbs and he drank 8 ounces during his run. What is his sweat rate? A) 8 ounces B) 16 ounces C) 48 ounces D) 56 ounces
