The first passageway is known as phosphagen and it has a fast rate of ATP production and utilizes creatine phosphate which is also used to restore ATP after it breaks down to supply and release energy. Second energy passageway is anaerobic glycolysis and this passageway is dependent on the energy that develops from glucose and uses this energy to form ATP and also does not compel the use of oxygen. This energy passageway takes part in the cytoplasm and breaks down the glucose into pyruvate. Third energy passageway is known as aerobic glycolysis. This energy pathway requires and uses oxygen to create ATP and to burn carbohydrates and fats. It occurs in the mitochondria and utilizes sustained energy production.
In the phosphagen passageway there is merely a limited amount of power for the muscles to contract because of the small amount of CP and ATP. Exercises for this need to be at a high intensity in a short amount of time. These exercises can include sprinting or weight lifting. With anaerobic glycolysis exercise or activities require a high intensity of energy in a somewhat long period of time. The time span can range from 30 seconds to 3 minutes maximum. The activities that use anaerobic glycolysis could be gymnastics or hockey. With aerobic glycolysis it involves a stagnant rate of ATP production and is practiced more during less vigorious activities in a longer amount of time. These activities can include a marathon or swimming.
If I were training to participate in a marathon the pathway that would be my central focus while training would be aerobic glycolysis. This is because marathons require to be able to sustain energy for a sustained amount of time. The type of activities I would incorporate for my marathon training would include running for 3 days a week, then adding in some form of cross-training exercises for the days that I do not run, and taking at least 2 days to rest. I would use these activities for the reason that running for 3 days can help train and prepare my body for the long race. Cross-training will also be beneficial because not only does it help increase your endurance but it also helps to train many different muscle groups in your body. Comprehending an understanding of the energy pathways can be very beneficial to your future training endeavors due to all activities and sports requiring different types and quantities of training and training the correct way can lead to success.
