How is energy made?
Energy is made in every cell of the body from the oxygen, food and water transported in the blood and pumped around the body by the heart.
Whats different if i have half a working heart?
Children and Young people with a single ventricle heart (half a working heart) have less energy than their peers because they may have less oxygen in their blood and only have one of the two pumps needed to drive blood around to every cell. Doctors who have researched this say that most heart healthy teenagers run at 100% energy level at rest and are able to increase that to 500% on activity. Young people with half a heart run on a normal energy level of between 50% and 75% which can only rise to 200% when active.
