  • Begins as soon as exercise finishes. 
  • Process takes around 5-8l of oxygen to compete. 
    • During this time: 

    1. Lactic Acid is removed
    2.Some glycogen in replenished
    3.Gradual decrease in ventilation levels to maximize oxygen delivery
    4.Gradual decrease in heart rate to maximize oxygen delivery
    5.Elevate core body temperature.

    Glucose is broken down into Pyruvic acid and is then converted to lactic acid because no oxygen in present. The oxygen consumed in recovery helps to reverse this process returning the lactic acid to pyruvic acid.
    • 50-75% of the pyruvic acid is oxidized in Kreb’s cycle and the electron transport chain creating H2O and CO2.
       
      •10- 25% of the pyruvic acid is reconverted into glucose
       
      LACTIC ACID REMOVAL TAKES BETWEEN 1-2 HOURS BUT CAN TAKE UP TO 24 HOURS DEPENDING ON ORIGINAL EXERCISE INTENSITY, BUFFERING CAPACITY AND RECOVERY METHODS USED.

    2. restore oxygen stores in venous blood, skeletal muscle and myoglobin.

    During exercise, oxygen dissociates with haemoglobin in the blood stream and myoglobin in the muscle cells.

    This fuels the aerobic energy system.

    Within the first minute of EPOC, oxygen resaturates the blood stream associating with haemoglobin.

    The graph above displays oxygen consumption post exercise decreases rapidly  before returning to resting levels.

    EPOC is always present after exercise. However, the size of oxygen deficit depends on the intensity and duration of the exercise.]]>     2023-09-13 13:50:21 UTC https://padlet.com/mills8/ifyrmafk05q86fim/wish/2702141659     Ways in which lactic acid can be removed https://padlet.com/mills8/ifyrmafk05q86fim/wish/2702142071 1. oxidation into carbon dioxide and water in inactive muscles & organs

    ATP and PC stores are depleted during exercise by the ATP/PC system.

    During the first 3 mins of EPOC, aerobic energy production continues, therefore providing energy to resynthesise ATP and PC.

    To do this, you need muscle phosphagon (the P in PC) so you can restore ATP bonds.

    Restoration of muscle phosphagon takes 30 seconds for 50% and 3 minutes for 100%.

    With phosphagon restored as well as energy, you can restore ATP and PC

    Energy + P + ADP = ATP
    Energy + P + C = PC]]>     2023-09-13 13:57:07 UTC https://padlet.com/mills8/ifyrmafk05q86fim/wish/2702154316     Oxygen deficit https://padlet.com/mills8/ifyrmafk05q86fim/wish/2702156173 what occurs at the beginning of exercise in the time taken to reach steady state. This is when we consume the amount of oxygen needed to support the given intensity of our exercise. 
    During this deficit period where our energy requirements outweigh the amount of energy we can produce from oxygen, we must rely on our phosphocreatine reserves and anaerobic respiration.]]>     2023-09-13 13:58:05 UTC https://padlet.com/mills8/ifyrmafk05q86fim/wish/2702156173     What are some of the signs of EPOC https://padlet.com/mills8/ifyrmafk05q86fim/wish/2702168890 Increased heart rate post exercise.
    Out of breath post exercise.
