Energy Systems

1. ATP-PC System (Anaerobic):

   • This system provides energy for short bursts of high-intensity activity, like sprinting or lifting something heavy.

   • It works really quickly, giving your muscles the energy they need almost instantly.

   • Lasts for about 10 - 15 seconds at maximum effort.

   • Think of it like a quick burst of power from a battery!
     
     

2. Lactic Acid/Glycogen System (Anaerobic):

   • Kicks in when the ATP-PC system runs out, providing energy for medium-intensity activities like running or doing push-ups.

   • It breaks down stored carbohydrates (glycogen) into energy, but it makes a byproduct called lactic acid, which can make your muscles feel tired and sore.

   • Lasts for about 30 seconds to 2 minutes.

   • It's like a backup generator kicking in when the main power goes out!
     
     

3. Aerobic System:

   • This is the system you use for longer, lower-intensity activities like jogging, biking, or playing sports for a long time.

   • It uses oxygen to break down carbohydrates and fats into energy.

   • It's slower than the other systems but can keep going for a long time without getting tired.

   • It can keep you going for hours if you're doing something like hiking or playing football.

   • Think of it like a slow-burning fuel that keeps your engine running smoothly!
     
     

These systems work together depending on how intense and how long your activity is. So, whether you're sprinting down a field, doing push-ups, or playing a game of basketball, your body is always using these energy systems to keep you moving!
