Energy for muscle activity comes from both glucose and fat. We are constantly using our fat stores for energy at rest. However, glucose is the main source of energy for high intense activities. But the storage form of glucose (glycogen) runs out quickly and needs to continually be replaced. To increase glycogen stores just before intense activities, we look to carbohydrates. Carbohydrates stay in the stomach a shorter time than protein or fat and are easily digested. The glucose then enters the bloodstream quickly for energy to exercise.
Eating more carbohydrates applies to just prior to, or during activity. Studies have shown, “Athletes who train while consuming relatively high fat diets may increase their body’s ability to use fatty acids for energy formation during prolonged exercise. So, bottom line…. The rest of your child’s diet needs to be balanced! Carbohydrates do not provide a sufficient amount of zinc, iron, vitamin B 12 or other nutrients. Balance is necessary to build up the storage of fat for energy, as well as provide adequate protein for muscles building and repair.
And of course, Hydrate, hydrate, hydrate!
So Amy, I wouldn’t hesitate to send a bag of cereal, to school with your kids to eat afterward, or even a few pancakes. The pancakes wouldn’t be so bad even eaten dry and cold!
Anyone else have ideas of transportable high energy snacks, resources, websites or books on sports nutrition??
