Training Methods and Energy Systems

Training Methods and Energy Systems

Understanding how our body produces energy Exploring different training methods Year 9 Physical Education

What happens in your body when you exercise?

Think about the last time you ran or played sport What did you feel happening in your body? How did your breathing change? What about your heart rate?

The Three Energy Systems

Our bodies have three different ways to produce energy Each system works at different times during exercise Understanding these helps us train more effectively All three systems work together during activity

ATP-PC System (Phosphocreatine)

Provides immediate energy for 0-10 seconds Used for explosive movements like sprinting or jumping No oxygen needed (anaerobic) Limited supply - runs out quickly Examples: 100m sprint, shot put, high jump

Anaerobic System (Lactic Acid)

Provides energy for 10 seconds to 2 minutes Used for high-intensity activities No oxygen needed but produces lactic acid Causes muscle fatigue and 'burning' sensation Examples: 400m run, intense gym workout

Aerobic System (Oxygen)

Provides energy for activities longer than 2 minutes Uses oxygen to break down carbohydrates and fats Can work for hours without fatigue Most efficient energy system Examples: marathon running, cycling, swimming

Energy System Activity

Stand up and try these activities: 10-second sprint on the spot (ATP-PC) 30-second high knees (Anaerobic) 2-minute gentle march (Aerobic) Notice how each feels different!

Key Takeaways

Your body has three energy systems that work together Different activities use different energy systems Training methods can target specific energy systems Understanding this helps improve your performance Next lesson: We'll design our own training programs!
