What is it? And how does it work?
ATP is required for the biochemical reactions involved in any muscle
contraction. As the work of the muscle increases, more and more ATP
gets consumed and must be replaced in order for the muscle to keep moving.
Because ATP is so important, the body has several different systems to create
ATP. These systems work together in phases. The interesting thing is that
different forms of exercise use different systems, so a sprinter is getting ATP
in a completely different way from a marathon runner!
ATP comes from three different biochemical systems in the muscle, in this
order:
- phosphagen system
- glycogen-lactic acid system
- aerobic respiration
