This is what everyone thinks, but they are not necessarily correct. The most important thing that your body needs during running any amount is oxygen, that’s where VO2max comes into play. VO2max is “the volume of oxygen a person can consume in one minute as he or she exercises at maximum exertion” (paragraph 4). With Team NOVA, their VO2max levels were measured before and after their nine months of training; and they were dramatically better after. It’s not the VO2max levels that help with receiving enough oxygen when running, it is merely an indicator. The amount of red blood cells present in your body help with your oxygen intake, as their primary job is to transport oxygen to the tissues of your body. The more red blood cells, the more effective your body is at transporting oxygen. Lastly, the main thing that helps your body with oxygen flow that, in turn, makes you physically ready for a marathon, is your heart. “Elite endurance athletes have extraordinarily powerful, and often unusually large, hearts…with sweat and perseverance, all of us can strengthen our hearts” (paragraphs 16, 17). A healthy heart means more oxygen flow, and eased breathing when running. In the instance of Team NOVA, after only nine weeks into their training, their hearts became more efficient, pumping more blood with less beats. Their arteries and veins became more elastic, easing blood flow, and they had more tiny capillaries and mitochondria, and they were
