All of these factors are important for peak athletic performance. A good blood supply and system of delivery ensures that oxygen and nutrients can be delivered to the muscles efficiently. A well-developed respiratory system helps to provide the body with the oxygen it needs during exercise. Adequate numbers of muscle mitochondria are important because these organelles are responsible for producing ATP, the energy currency of the body. Finally, good supplies of nutrients are necessary to fuel muscle contractions and support recovery after exercise.
