Physical Activity and Energy Pathways Coursework

visible Activity and vigour Pathways - Coursework ExampleWhen I make healthy everyday exercise choices, I function to make better food choices. Fruits and vegetables replace candy bars and chips in my diet when I am making better food choices. In my mind, I feel exercise should not be sabotaged by poor food choices. This affects my social activities as well. Instead of going to the movie with friends and family, I chose to do more(prenominal)(prenominal) physical activities. For example, I will go bowling or skating. I like to be more active. This is all due to my effort to walk a couple of miles a day.The three fitness activities in which I have been involved and in which I will describe Energy Pathways will be running, swimming, and tennis. The three Energy Pathways are adenosine triphosphate-CP, LA, and O2. ATP-CP can be defined as Adenosine Triphosphate which is a chemical unite formed with the energy released from food and stored in all cells, particularly muscles. The ene rgy released by the breakdown of this complex can make the cells perform work. The breakdown of ATP produces energy and ADP. CP or Creatine Phosphate is a compound stored in the muscle, which when broken down aids in the manufacture of ATP. The combination of ADP and CP results in ATP. LA or Lactic Acid is a fatiguing metabolite of the lactic acid system cause by the partial breakdown of glucose. O2 is when in aerobic running ATP is produced from food mainly fat and sugar. This system produces ATP in abundance and is the prime energy source during endurance activities. When endurance running the Energy Pathways employ are 10% ATP-CP and LA, which occurs in the first 1-45 seconds. The LA-O2 Energy Pathways are used 20% in the 45-120 seconds. The O2 is used 70% for the rest of the activity. During swimming the Energy Pathways used are 10% ATP-CP and LA, which occurs in the first 1-45 seconds. The LA-O2 Energy Pathways are used 20% in the 45-120 seconds.
