which energy does the body burn first during exercise? - ess energy storage system

Your body is operated by three major energy systems. Your ATP-
PCr system involved in a short period of time
Anaerobic energy.
By breaking down the carbohydrates stored in the muscles and liver, your mashing system generates energy.
Your aerobic system uses oxygen and fat to produce slow but longlasting energy.
In most types of exercise, your body uses some combination of the three energy systems at the same time, but depending on the needs of your body and the type of activity you are doing, it may emphasize mutual use. ATP-
The simplest of the three energy systems is your ATP-PCr system.
ATP represents the acid of the three-phosphate gland, and the acid of the three-phosphate gland is the chemical form of the raw energy in the body.
PCr refers to phosphate, which is a compound attached to each ATP molecule.
In your skeletal muscle, ATP-when muscle fibers receive a signal of neural contraction-
PCr molecules are separated from each other due to complex chemical reactions.
This separation releases the energy that causes muscle contraction.
This energy system is mainly used for short-time movements that last less than 10 seconds, such as quick jumps or sprints.
Sugar decomposition system sugar decomposition energy system produces ATP through the decomposition of carbohydrates and sugar in the body.
Glucose or sugar is stored in your liver and skeletal muscle.
When needed, your muscles break down glucose by using special enzymes and eventually turn sugar into ATP.
ATP is then used for muscle contraction.
This system is best suited for less than two minutes of activity at high intensity.
This includes sprints and other strenuous sports for a short period of time.
The aerobic system mainly uses fat to produce energy, but it can also use stored carbohydrates and proteins.
Aerobic means "aerobic", which means that oxygen is needed in the process of decomposing fat storage for energy.
Fat molecules are extracted from various stores around your body and converted into ATP through complex chemical reactions that occur within your muscles.
Your aerobic system produces a lot of continuous energy and is ideal for long periods of exercise
Long-distance running or cycling activities.
Although each of these three energy systems works independently, they can all be used by your body at the same time.
The most used energy system at any given time depends on the intensity and duration of the exercise you are doing.
All three energy systems will be opened simultaneously at the beginning of the movement;
However, each energy system is recruited when the current energy system that is mainly used is exhausted.
