====Summary====                   
{{$demo.summary}}



====Procedure====  

  - Divide the class into small groups and assign each group a physical activity type (e.g., sprinting, endurance running, weightlifting).  
  - Have groups perform their activity for a set time using exercise equipment or bodyweight exercises, timing their performance with a stopwatch.  
  - Each group reflects on which energy system(s) were dominant during their activity and why.

====Variations====
  * Replace exercise equipment with bodyweight movements (push-ups, burpees, jump squats, running in place).  
  * Use real sports scenarios (soccer sprint vs. marathon pace) and have students analyze energy demands without doing the activity.  
  * Have students design a training plan that targets one specific energy system.



====Safety Precautions====
  * Ensure students warm up before exercise to reduce injury risk.  
  * Supervise equipment use carefully, especially treadmills or weights.  
  * Adapt activities for students with medical conditions or lower fitness levels.  
  * Provide hydration breaks to avoid overheating.



====Questions to Consider====
  * Which energy system provides energy the fastest? (ATP-PC system, but only for a few seconds.)  
  * Why does the glycolytic system cause fatigue quickly? (Because it produces lactic acid as a byproduct.)  
  * Which energy system is most important for long-distance running? (The oxidative system, as it provides sustained ATP production.)  
  * Can multiple energy systems work at once? (Yes, systems overlap, but one is usually dominant depending on activity intensity and duration.)  
  * How could understanding energy systems help athletes train more effectively? (By tailoring workouts to improve the system most used in their sport.)
