Answer:
Marathons
Step-by-step explanation:
Carbohydrate loading (aka. carbo-loading) is beneficial to individuals who take part in sports, more specifically marathons.
Carbohydrates are a very good source of energy, this means that when a carbohydrate is broken down into carbon dioxide and water, it releases a lot of energy with it. Energy is needed for day to day life, and without it we would die, however for individuals who participate in marathons, they usually carbo-load before a big race to get a lot of carbohydrates stored in their body for when they need the energy in the race.
