1. Energy Systems Development Part I

2. What is in a Name?  Cardio  Conditioning  Energy Systems Development

3. 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

4. Energy System Utilization  Aerobic  Intensity?  Time?  Anaerobic  Intensity  Time Remember, it lies on a continuum!

6. 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

7. Adaptations to Anaerobic training Central Similar to Aerobic Peripheral pH buffering Lactate production Glycolitic enzymes

8. Complementary aspects of training  Peripheral Aerobic Adaptations  Peripheral Anaerobic Adaptations  Central Adaptations
