What is your aerobic system?

"The working ability of a muscle depends on sufficient blood flow and intake of oxygen and nutrition.

The body uses two different systems to supply the muscles with energy:

1) Aerobic system: Carbohydrates and fat react with oxygen to metabolize into carbon dioxide and water.

2) Anaerobic system: Carbohydrates are used for energy production without oxygen and metabolized into lactic acid or lactate."
