To create movement, muscle cells produce muscular contractions by converting chemical energy into mechanical energy. This is accomplished by production of the molecule adenosine Triphosphate (ATP) “currency of the body"). ATP can be produced in the muscle cells by using three types of components:
1. Creatine Phosphate
The most important compound for endurance is the carbohydrate molecules which break down in two ways- Aerobically in the presence of oxygen, and- Anaerobically, in the absence of oxygen where the end product is lactic acid.
The basic fact remains that the energy systems of the muscles are linked and actually represent a continuum.
What is the importance of this continuum?
How does it affect intensity of workouts from easy to hard?
How do you nutritionally support various workouts based on energy system involvement?
