What sort of food would this athlete eat for energy? Task What sort of food would this athlete eat for energy?

Carbo-Loading The energy to run comes from food, and more specifically carbohydrates Carbo-Loading refers to boosting the amount of glycogen in the body before competition Knowledge of the nutrients of a balanced diet will help you understand how it works

Carbo-Loading Diet Plan Eating more protein in early part of week will help runners’ muscles to repair Eating high levels of carbohydrates later in the week, will increase glycogen stores in liver and muscles Important to take in food in the first 2 hours after competing or training. This will restock carbohydrates used during activity

Blood Flow During Exercise When exercise begins, blood is sent to the working muscles Less blood is therefore available to digest food in the gut, which can cause cramps The flow of blood from other areas into the muscle is known as blood shunting. This is why an exercise session should not start until 2/3 hours after the last meal
