Learn what is energy, how to increase people's energy levels and maintain them in different situations, when rest is the perfect recovery tool and how to perform exercises for better energy management.What are the factors that makes us move better?  By understanding these factors it is possible to improve management of the body's capacity for movement and to help maintain optimum levels of energy.

Suggested prior learning: A basic understanding of body systems or appropriate course such as Human Anatomy and Physiology.

Lesson Structure

There are 7 lessons in this course:

1. Energy and Work -

   • Explains how energy is used in the human body to create work and power

2. Energy Pathways

   • Looks at energy pathways during rest, work and recovery

3. The Acid-Base Balance -

   • Explains the significance of the acid-base balance in the body

4. Osmosis & Diffusion -

   • Explains movement of materials in and out of living cells

5. Atmospheric Pressure

   • Examines the affect of changing atmospheric pressure on the human body

6. Temperature Regulation

   • Centres on temperature regulation in the body

7. Ergogenic Aids to Performance

   • Examines ergogenic aids to body performance during activity/exercise

Each lesson culminates in an assignment which is submitted to the school, marked by the school's tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.
