At the onset of exercise (first 60 seconds) which Energy system activates is first to full capacity
ATP-PC system
Which energy system dominates between 30sec to 2 minutes
Glycolysis system
Do all energy systems(ATP-PC system, Glyscolsis systems, Aerobic Metabolism System) turn on at the same time, or do they turn on at different times
Same time
Aerobic metabolism system just takes a bit longer to get to full capacity
Which energy system dominates from 5 minutes onward
Aerobic Metabolism System
Are the ATP-PC system and Glycolysis system, Aerobic or Anaerobic system
Anaerobic systems
what is the end product of glycolysis
Lactic Acid
what is the concentration of Lactic Acid in the blood at rest
1 mM (mili molar)
What is the ideal concentration of Glucose within the blood
5mM
what is O2 deficit and O2 debt (refer to page 24)
O2 Deficit: O2 deficit refers to the initial period of exercise when oxygen consumption (VO2) is not sufficient to meet the increased energy demands of the muscles. When you start an activity, there is a lag between the onset of exercise and the point at which your oxygen consumption matches the energy requirements of the exercise. During this phase, the body relies on anaerobic energy systems to produce ATP (adenosine triphosphate), which is the primary energy currency in cells. This means that the muscles are not receiving enough oxygen to fully support aerobic (oxygen-dependent) energy production.
O2 Debt: O2 debt, also known as excess post-exercise oxygen consumption (EPOC) or the “afterburn,” refers to the additional oxygen consumption that occurs after exercise to help the body recover from the oxygen deficit created during intense physical activity. During exercise, the body uses anaerobic processes, such as glycolysis, to generate ATP. These processes produce byproducts like lactic acid, which need to be metabolized and cleared from the body. Additionally, other post-exercise processes, such as restoring oxygen levels in muscles, replenishing glycogen stores, and regulating body temperature, also require energy and oxygen.
