Multiple Choice

Refer to Scenario 3.1. The term "carbo loading" refers to eating excess carbohydrates over a period of several days before running long distances. Why is this practice beneficial to long distance runners?

A) Excess carbohydrates turn into fat, and fat stores energy.
B) Carbohydrates are complex chains of amino acids that take a lot of time to breakdown, therefore providing the necessary energy to run the body and muscles for a longer time.
C) Eating excess carbohydrates is equivalent to excess substrate concentration and slows the metabolic rate, providing more energy for longer time periods (like a long- distance run) .
D) Eating excess carbohydrates allows your body to utilize its proteins better to make your muscles stronger.
E) Eating excess carbohydrates over a period of time allows the excess carbohydrates to be stored as glycogen in your liver and muscles. During a race, the glycogen is converted to glucose and, therefore, the glucose can be utilized to provide the body with more energy.
