Energy Systems Development Part I
What is in a Name? Cardio Conditioning 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!

Adaptations to Aerobic training Central Respond due to intensity Short-term (4-6 weeks) Stroke Volume Myocardial Contractility Blood Volume Hemoglobin affinity Peripheral Respond to Volume Long-term (months) Oxidative and Anaerobic Enzymes Mitochondrial Density Capillary Density
Adaptations to Anaerobic training Central Similar to Aerobic Peripheral pH buffering Lactate production Glycolitic enzymes
