This is about the 400m sprint, and the energy systems that is uses, from Adenosine Tri Phosphate, to the Lactic Acid system

The event that I have decided to undertake from the summercater unit this term and elaborate more on is fellowship and understanding of the 400-meter run.

This event is usu aloney taken place on a full size athletics field, which consists of one wholly lap in a fast sprint, which takes around a time of a minute.

In that minute the runner would experience all factors of the hurry, from intensity to recovery.

In the 400 meters, intensity relates to the chosen speed, which is usually uttered as a percentage of your maximum effort, and how hard you train.

Other aspects include Duration, which is closely linked to intensity. For example the higher the intensity of your wreak is, the shorter the duration will be.

Another major factor in the 400-meter race is endurance because the athlete must maintain a sprint for such a long distance comp ared to the 100 and 200-meter sprint.

These are only a few of the factors that contribute to the outcome, but a car cannot run on no fuel, just alike our fuel for the 400m race is the competency systems.

There are 3 strength systems that we classify, from the amount of work we are creating for ourselves.

These consist of ATP, Lactic Acid, and aerobic capacity

In the 400m though, we use two of the three energy systems.

The first, and the most rich of all is Adenosine Tri phosphate, or simply, ATP, which is the immediate usable form of chemic energy for muscular activity. This is one of the most important of the energy rich compounds that is stored in all stalls, particularly muscle cells. all in all forms of chemical energy available from the food we eat must eventually be transferred into ATP before the muscle cell can utilize them

Actively contracting muscles obtain...
