A 29 year old, 55kg, 161cm, female marathon runner averages five 1-2 hr training sessions during the week, and a 2-3 hr easy run on Saturdays. She has some blood work done and completes a 3-day diet record. She has a serum ferritin value of 28 ng/ml and a transferrin saturation of 22%. Her average daily intake of the following vitamins and minerals is: iron, 13mg; calcium, 800 mg; Vitamin E, 15 mg; Vitamin C, 100 mg. Her average caloric intake is 2500 kcal, of which 50% is CHO, 20% is PRO, and 30% is fat. Her sweat rate during training is typically 1.4 L/hr.

Based on these values, is this athlete in negative, positive, or neutral energy balance? What is her status for these particular vitamins and minerals? What are some potential problems associated with these deficiencies in these particular vitamins and minerals, and how would you suggest she rectify any deficiencies, if necessary, without using supplements?

What is her daily CHO consumption in g/kg/day? Based on her training status, is this value in line with the current recommendations? If not, what should her CHO intake range be, and how would you recommend she address the situation?

What is her PRO consumption in g/kg/day? Based on her training status, is this value in line with the current recommendations? If not, what should her PRO range be? Describe a PRO intake strategy that would allow her to achieve her overall daily number in g/kg, while ensuring she maintains protein synthesis throughout the day.

Develop a pre, during, and post-training feeding and hydration plan for this athlete based on current recommendations (be mindful of ways to reduce gastric distress).
