⚡ Part 1: Energy System Basics

Quick Reference:
• ATP-PC System: Immediate energy (0-10 seconds)
• Glycolytic System: Short-term energy (10 seconds-2 minutes)
• Oxidative System: Long-term energy (2+ minutes)

1. Which energy system provides the FASTEST energy for muscle contraction?

ATP-PC System

Glycolytic System

Oxidative System

2. The Glycolytic system can work with OR without oxygen. What is it called when it works WITHOUT oxygen?

Aerobic glycolysis

Anaerobic glycolysis

Oxidative phosphorylation

3. Which energy system can work for HOURS during steady-state exercise?

ATP-PC System

Glycolytic System

Oxidative System

4. Fill in the blanks:

The _________ system uses creatine phosphate to quickly regenerate ATP, while the _________ system breaks down glucose for energy.

🏃 Part 2: Real-World Applications

5. Match each activity to its PRIMARY energy system:

100-meter sprint

800-meter run

Marathon running

Powerlifting (1 rep max)

Oxidative System

ATP-PC System

Glycolytic System

ATP-PC System

6. A basketball player drives to the basket (10 seconds), then jogs back on defense (30 seconds). Which energy systems are being used?

ATP-PC System during the drive

Glycolytic System during the drive

Oxidative System during the jog back

All three systems work together

7. Explain why a sprinter gets tired after 30 seconds but a distance runner can maintain pace for hours:

🎯 Part 3: Advanced Application

8. Extension Activity: Design a training program that targets each energy system. Include specific exercises and time durations:

ATP-PC Training:

Glycolytic Training:

Oxidative Training:

9. Critical Thinking: Why might an athlete need to train all three energy systems even if their sport primarily uses one?

🏆 Success Criteria - Check Your Understanding:

I can identify the three energy systems

I understand the time frames for each system

I can match activities to their primary energy system

I can explain how energy systems work together

I can design training for specific energy systems
