This energy takes three forms.
What are the three sources of energy your body uses in order.
Macro means large and these basic nutrients are necessary in large quantities to sustain our growth metabolism and other bodily functions.
Fats and carbohydrates or carbs are the primary fuels for your muscles when you re working out.
Carbohydrates such as sugar and starch for example are readily broken down into glucose the body s principal energy source.
These nutrients must come from food and they re vital for disease prevention growth and good health.
Your aerobic system uses oxygen and fat to produce slow yet long lasting energy.
As exercise intensity.
The energy or calories in the food we eat comes from three macronutrients.
Atp which stands for adenosine triphosphate is the sole source of energy for all human metabolism yet very little of this fuel is actually stored in the body.
Carbohydrates come through the glycolytic system creating pyruvate that continues right into the aerobic system.
Most of the body s activities use a continuum of all three energy systems working together to ensure a constant supply of energy.
See table 2 1 estimated energy stores in humans the body can store some of these fuels in a form that offers muscles an immediate source of energy.
Most notably sugars and fats are used by the body as energy sources.
The utilization of fat carbs during exercise.
However these micronutrients are required in smaller.
Fats are metabolized more slowly than carbs and are the preferred energy source during long duration low intensity exercise such as walking.
Atp pc anaerobic glycolysis and aerobic phosphorylation.
The regulation of fuel selection during exercise is under complex control and depends on several factors including diet as well as intensity and duration of exercise 3.
Carbohydrate fat and protein.
In circumstances such as starvation the body will begin to break down.
Each system uses different starting fuels each provides atp at different.
The body uses 3 different systems to supply cells with the necessary atp to fuel energy needs.
It is within this system that carbohydrates fats and proteins may be refined in order to create atp.
Proteins fats and carbohydrates.
Your glycolytic system produces energy through the breakdown of carbohydrates stored in your muscles and liver.
The aerobic energy system.
Within these cells and from these energy sources adenosine triphosphate atp is formed to provide fuel.
Essential nutrients are compounds the body can t make on its own or in enough quantity.
The body uses carbohydrate fat and protein to provide necessary energy to sustain cellular activities both at rest and during exercise 3.
The aerobic energy system is where we utilize all 3 of our fuel resources.
Your atp pcr system is involved in short term anaerobic energy.
Our bodies require other nutrients too like essential vitamins and minerals.
