Essay --

Lactic Acid had a pretty nasty repute up until recently. It was thought to cause muscle fatigue and muscle cramps in not only basal marathon runners and marathon runners, exactly in any sport. I had recently completed my first marathon and was sick somewhat the lactic acid buildup more than anything. Around the sixteenth greyback of the Atlantic City Marathon I felt the tiredness creep up from my toes into my hips. Right away, I thought nigh lactic acid. beforehand doing the research for this paper, anything I knew about lactic acid was told to me by my uplifted school cross country coach and my brother, who runs cross country and remains for Lock Haven College. When my legs would get tired during training, I was told to lay on the floor with my legs up against the wall so the lactic acid would drainage out of them. Who knew that everything I was told was a lie? I enjoy a lot of coaches that still believe that lactic acid is bad and decline to give up on that fact, but w ithout doing the research, they will never know the truth. When running persistent distances, the body uses two systems for energy the aerobic and the anaerobic energy systems. The aerobic energy system uses oxygen in the process, date the anaerobic energy system does not use oxygen. According to the American Running Association, adenosine triphosphate is a high-energy molecule and the main stemma of energy for muscle contractions. When we exercise aerobically, ATP is derived from the oxygen that we breathe in. Glucose and glycogen is nevertheless also required to convert this oxygen into energy. When the amount of ATP needed cannot be derived quickly enough with traditional oxygen intake and conversion to energy, the body then relies on the anaerobic energy system, which created as a byproduct, la... ...ned by the heart and the blood vessels. So if you carry on training a guy, you will not improve his aerobic capacity, but his performance will still improve because the lactate acid limen is not limited by the cardiovascular system---its determined by the quality of the muscles. This means that the more a runners muscles be adapted to this kind of running, the better they will be during a long run or ultra marathon (Cox). When I think about these men that have run ultra marathon after ultra marathon, it kind of inspires me to do one someday. After I think about it for a little bit though, I go back and immortalise what it felt like running 26.2 miles. I could never imagine what my legs and feet would tint like after running even 27 miles, let altogether 50 or more. People like this are so inspirational and what ever they put their mind to, they can accomplish it.
