Galen Rupp: The Boston Marathon

Galen Rupp, an American marathon runner is looking to run the Boston Marathon. Not only being known for the history of the race but the distance preparation of the racers before is key to them being able to complete the race. This marathon has a distance of twenty-six miles or 42.195 kilometers from start until finish. Running this race will take a lot of energy and power of Rupp to finish so using the right energy system effectively is important. This starts with a breakdown of what physical activity generally does. All physical activity requires transfer of energy. This can be seen through bioenergetics. Bioenergetics is the conversion of foods like fats, carbs, and proteins into a chemically usable forms of transferring energy for biological

Creatine phosphate and adenosine diphosphate are put through an endergonic reaction (anabolic) to make ultimately adenosine triphosphate and creatine. This system is a very rapid production of ATP and usually occurs during short-term and high intensity activities on the muscles. A small amount of creatine phosphate and ATP are already stored in muscles, but the amounts needed for muscular contraction is larger so this process is necessary for Rupp is his start of the race. It is, however, instantaneously available and is essential at the onset of activity, as well as during short-term high-intensity activities. The second system the body uses isn 't as immediate but is short-term effect in producing ATP in activity. Anaerobic glycolysis is a system that doesn’t require oxygen but uses glucose to form ATP. This pathway occurs within the sarcoplasm through two separated phases: investment and generation. The investment phase give one energy of ATP to glucose to help break it down. The breakdown or net gain of glucose into components of two ATP and two pyruvate is generated in this generation phase. This second system of anaerobic glycolysis is very important for Rupp as his muscles will produce ATP somewhat rapidly during his exercise of running. This activity requires maximal amount of effort over a period of up to two minutes in length. So as Rupp starts his run his power must be at the max to push him through the race and keep his endurance up before switching to the third system prior to his steady-state ever being
