Energy And Energy Sources

Uses oxygen for energy production Includes activities that are long duration Includes activities that are of a moderate intensity

Does not use oxygen for production of energy Includes activities that are of a short duration Includes activities that are of a high intensity

Energy source of aerobic exercise They require oxygen to break down the fat into energy They are slow to break down Once broke down they give large quantities of energy

They are an energy source for both aerobic and anaerobic activities Do not need oxygen to breakdown down into glucose Doesn’t give as much energy as fats Quicker to break down and release more energy then fats

Muscle fatigue Build up of lactic acid Oxygen deficit - during recovery oxygen is paid back to - replenish myoglobin stores with oxygen, remove lactic acid, allow energy stores in the muscle to be replenished

Increased heart rate Increase stroke volume Increased blood pressure Increased cardiac output Vascular shunting occurs

Increase depth of breathing Increased rate of breathing Increased gas exchange Increase tidal volume Oxygen deficit

Amount of blood pumped from the heart in one min Stroke vol x heart rate

Amount of time heart beats per minute

Amount of blood pumped from the heart in one beat
