Energy Systems Development

What are the Different Energy Systems?

Aerobic

Anaerobic

ATP-PC

Stored ATP

These are rarely absolute, but usually flow on a continuum

What are the primary variables that determine energy system? Intensity Time

Energy System Utilization

Aerobic Intensity? Time?

Anaerobic Intensity Time

Remember, it lies on a continuum!

Stroke Volume

Myocardial Contractility

Blood Volume

Hemoglobin affinity

Peripheral

Respond to Volume

Long-term (months)

Oxidative and Anaerobic Enzymes
