Fuel Source
I am the predominant source of fuel for the aerobic system
Carbohydrates
The amount of ATP produced per glucose molecule
This drop in performance over time in endurance events occurs partly because the body shifts fuel, and byproducts build up
Fatigue
The three sequential steps the body uses during recovery to replenish energy stores: ingestion, digestion, and this.
Transportation
The processes of all three energy systems working together to provide a constant supply of ATP to the muscles.
Energy System Interplay
Once glycogen stores are depleted, the body shifts to this fuel source during prolonged aerobic activity.
Fats
The pace of production of the aerobic system
Medium Pace
This process helps control body temperature by releasing water.
Sweating
These two macronutrient stores must be replenished via ingestion and digestion during aerobic recovery.
Carbohydrates and Proteins
The time the aerobic system approximately becomes the dominant system.
1 - 3 minutes
This macronutrient is used sparingly by the aerobic system and primarily serves as a backup fuel source.
Protein
The process by which the body uses fat earlier to ‘save’ glycogen for later such as a sprint finish
Glycogen Sparing
Athletes with higher cardiac output can sustain higher intensities for longer because they can deliver this more effectively to active muscles.
Oxygen
If intensity and duration of aerobic performance increase, this happens to the recovery time.
It increases
The dominant system initially
ATP-PC
This process involves the breakdown of glucose in the presence of oxygen to produce ATP.
Aerobic glycolysis
Aerobic Athletes pace themselves because...
The aerobic system can not sustain high-intensity for long periods of time
This gas, produced in elevated quantities during sustained aerobic activity, can contribute to fatigue by interfering with oxygen transport.
Carbon Dioxide
The time taken to recover post event
12 - 48 hours (dependant on duration of activity)
Intensity of Anerobic Glycolysis
Medium Intensity
A strategy used by endurance athletes to increase the amount of glycogen (stored carbohydrate) in their muscles before an event
Carbohydrate Loading
For prolonged exercise, the aerobic system remains dominant until this fuel source begins to run low.
Glycogen
Excess water produced and retained in muscles post-exercise might cause this undesirable physical effect, making movement stiff or uncomfortable.
Swelling and Stiffness
This gas assists recovery by enabling the aerobic resynthesis of ATP and restoring energy reserves.
Oxygen
The aerobic system can revert back to the anerobic system. (TRUE or FALSE)
