What laboratory test is the best predictor of end times for a race of 100 km (62 miles or more than twice as far from a marathon)? A study from Yokohama, Japan suggests that the device is an ECG to the size of the left ventricle, ventricular action (British Journal of Sports Medicine, Volume 40, 2006), which, how much blood the heart pumps with each beat. This would be expected to predict how fast you can run for short distances inYou so fast that the limiting factor is the lack of oxygen to move. This study is surprising given that most athletes believe that the major limiting factor for the implementation of very long distances, the amount of fuel is your muscles, you can store.
Now we know that the limiting factors for ultra-endurance competitions to those for shorter distances are similar: the time it takes to move oxygen from the blood into the lungs to your muscles. This is how much blood the heart determinedPump and can carry as much oxygen your blood. Since 98 percent of the oxygen in the blood is carried by the hemoglobin in red blood cells, the higher your red blood cells, the more oxygen you can run. However, it is an important factor in how fast your heart can pump blood into the muscles, and this is determined by the strength of your heart muscle. The longer and harder you train, by you, the stronger the heart, and this is a fat means the left ventricle. TheRunners, the most miles in the heart of the training was the strongest and the best end times. So if you are in any sport requires extreme endurance competition, you have to spend a lot of time, you also need to strengthen training and intense exercise once or twice per week on your heart.
