Question

Emma is a 19-year-old national level elite triathlete, and she trains about 25 hours per week with 5 hours as strength exercises. Her BMI is 20, and her percent body fat is 15%. She eats a varied diet but does not like fruits and vegetables and tends to focus on carbohydrate-rich foods and meat and cheese, but because of her schedule, she eats irregularly and eats out a lot, tending towards sandwiches and wraps.

Given Emma competes in long endurance events, she should:
Increase fat intake before an event to spare glycogen
Increase carbohydrate intake before and during the events
Increase protein intake to twice the average intake for sedentary Canadians
Decrease fat intake as much as possible
Increase carbohydrate intake only during the events

Emma would benefit from carbohydrate loading which would:
Increase efficiency of glucose and ATP utilization
Increase muscle glycogen stores so they last longer
Increase glycogen use and spare fat stores
Increase fat oxidation enzymes for more efficient fat use during exercise
Increase fat stores and spare glucose use
