The body has three energy systems

· Anaerobic alactic energy system

· Anaerobic milk energy system

· Aerobic energy system

 

 

Energy is needed to sustain growth,

daily activities and exercises. The quantity

of energy needed during training by the body

depends on the intensity and duration of the

exercise.

 

Title: 3 Alactic Anaerobic Energy System 

 

The alactic anaerobic system is found in both types of muscle fibers, it

it does not require oxygen and does not produce lactic acid. It is used

for fast dynamic actions that are high in energy but short in duration.

Anaerobic Milk Energy System

The anaerobic dairy system does not require oxygen but does not

produce lactic acid and is commonly used for activities that do not change

between 10 seconds and one minute.

Aerobic Energy System

This aerobic system works by breaking down carbohydrates, fat

acids and some amino acids. This system requires oxygen and can

apply for longer periods of time with lower energy output.

Overall, the results

All three energy systems contribute at the beginning of training, but at

the contribution depends on the individual, exerted effort, or on

the percentage at which energy is used. The above graph shows how energy

systems contribute over time when they exert 100% effort. The

thresholds (T) indicate the point at which the energy system is

exhausted (Specific training will improve time thresholds).

 

Anaerobic (ATP) energy system

Adenosine triphosphate (ATP) in the store

muscle lasted approximately 2

seconds and the resynthesis of ATP by

Creatine Phosphate (CP) will continue

until the CP stores are exhausted,

approximately 4 to 8 seconds. It gives

about 6 to 10 seconds on the ATP

production.

Title: ANAEROBIC

 

In anaerobic lactate system

After stores in HF are exhausted at

body spas to store glucose for

ATP. The breakdown of glucose or

glycogen under anaerobic conditions

leads to the production of lactate

acid. This energy system must continue

approximately 2 minutes maximum.

 

Under Aerobic Energy System

Aerobic energy system uses protein, fat

and ATP re-synthesized carbohydrates. this

the energy system can evolve to such an extent,

one can perform extreme feats of endurance

like with Ultra Marathon runners.

Energy system comparison

Main differences between Aerobic and Anaerobic exercise

Anaerobic load is what provides energy to the cells and the processes in them without the presence of oxygen. Anaerobic work is provided by the Creatine phosphate and lactate systems. This mode of energy security ensures the release of large amounts of energy quickly and in a short time. Work in this mode is performed by white (fast) muscle fibers, which have high contractility but "tire" very quickly. Oxygen debt accumulates, which is extinguished after work - that is, after anaerobic loading, the body recovers aerobically (you will feel it through increased breathing). The anaerobic mode of operation is extremely uneconomical. Decomposition of carbohydrates for energy in anaerobic mode produces 13 to 19 times (depending on whether the decomposition takes place in the muscles or the liver) less energy than if the same amount of carbohydrates is decomposed aerobically. This mode is characterized by a high pulse rate (about 180 beats / min). With a force load of 85-95% intensity and a duration of about 20 seconds, oxygen consumption is 80 to 100%. At high power loads at 95-100% intensity with a short duration (only a few seconds), the oxygen consumption is minimal (power tripping loads).
