Topic: Exercise and Your Body
Subtopic: The Non-Oxidative Energy System (Glycolytic System)

 

Learning Objectives:

By the end of the lesson, learners should be able to:

  1. Define the Non-Oxidative Energy System.
  2. Describe how the body uses it for exercise lasting up to 2 minutes.
  3. List examples of sports or drills where this system is dominant.

 

Previous Knowledge:

Learners have studied the Immediate Energy System and understand short bursts of energy in sports.

 

Instructional Materials:

  • Lactic acid buildup charts
  • Anaerobic training video
  • Diagram of glycolytic pathway
  • Exercise cones and stopwatch

 

Anticipation (Warm-Up) – 5 minutes:

Ask:

  • What happens when you keep running after the first 10 seconds?
  • Why do your legs start to feel heavy?

Activity:

  • 45-second continuous run, then short stretch

 

Building Knowledge (Main Lesson) – 25 minutes:

  1. Definition of the Non-Oxidative Energy System:
  • Also called the glycolytic system
  • Produces energy without oxygen
  • Uses glucose to make ATP
  1. Characteristics:
  • Provides energy for 30 seconds to 2 minutes
  • Produces lactic acid
  • Causes muscle fatigue
  1. Examples of Activities:
  • 400m sprint
  • Wrestling
  • Basketball fast breaks
  • High-intensity interval training (HIIT)
  1. Limitations:
  • Not sustainable for long periods
  • Causes discomfort from lactic acid buildup
  1. Importance:
  • Builds endurance
  • Improves tolerance to fatigue

 

Learners’ Activities:

  • Run 200m and observe breathing and fatigue
  • Draw and label the glycolytic pathway
  • Compare performance between a 10-second sprint and 1-minute run
  • Create a workout routine using this energy system

 

Consolidation (Review and Assessment) – 10 minutes:

Review Questions:

  1. What is the glycolytic system?
  2. What energy source does it use?
  3. Name one disadvantage of this system.

Mini Quiz:

  1. The glycolytic system provides energy for: A. Long-distance jogging
    Sprinting under 10 seconds
    C. Moderate efforts up to 2 minutes
    D. Rest periods
  2. The by-product that causes fatigue is: A. Carbon dioxide
    Water
    C. Oxygen
    D. Lactic acid

 

Homework / Assignment:

  1. Research and list 5 exercises that depend on this system.
  2. Interview an athlete who plays a moderate-intensity sport.
  3. Describe how they manage lactic acid buildup.

 

Notes – Detailed and Explained:

This energy system is vital for sports requiring moderate effort over a short time. Learners benefit by connecting physical feelings with biological explanations.

 

Expanded Notes / Instructions:

  • Use real sport examples to clarify usage
  • Reinforce pacing and short recovery drills

 

Inclusive / Differentiation:

  • Provide labeled pathway templates
  • Let learners perform activities at comfort level

 

Teacher’s Reflection:

  • Did learners understand how this system differs from ATP-PC?
  • Were they able to identify lactic acid effects?
  • Did they creatively apply knowledge to routines?
