When I was a teenager there was a younger boy who wanted to improve his positions in long-distance races so he trained more and harder. What do you think happened to him? Or the guy that blasted off in every race at the front with the eventual winners, only to fall back later because he had run out of breath? And what advice do you think I should give this lady whemaileded me? Should I tell her to run faster anshe'llll run faster times?
Here's the content of email: Clive, this is Leya from Miami, Florida. I am writing to you because I have been running now for almost 2 years, but there is no improvement, I still run the same route and I run the same time even though I have tried to improve, when I get treadmilled however, I have noticed that it is much easier, I can do a mile in 11 minutes at 6.0mph. Is there any book that you can recommend to me that would help me train, see, I have this dream of being able to enter a race some day before I turn 25 (I'm only 18) I know its a long time from now but training has become my passion, I just don't know how to train, I'm stuck, please help!!!! Thank you for your time!!! Hope you can help!! '
Exercise: After reading the contents of this article and answering a few more questions, I want you to write the rLeya'so Leya's letter. Have you go pen and paper ready to make a few notes? GI'll so I'll begin. Cardio-Vascularo-VasMusculard Muscualr Systems
As you know, when you run you breath in oxygen from the air and breath out carbon dioxide using the respiratory system. The lungs then interface with the heart and the oxygen intake is then transferred to the heart and mixes with the blood. You can feel your heart beat rises as your heart pumps the oxygenated blood to your muscles through the veins - using the circulatory system. The muscles have little black nodes inside them. These little black nodes combine oxygen with glycogen from carbohydrates to produce the energy to cause a muscular contraction and it is the repetition of these contractions that propels you forward a step. This is metabolism in the muscular system. Then the arteries take the waste product of this combustion back to the heart - the carbon dioxide, which is then transferred to the lungs and exhaled.
