We all want more energy! But how is energy created within the human body? What factors affect it and what can we do to increase energy. This online course investigates all this by diving into the science of human bio-energetics.
This course is suitable for anyone with an interest in human physiology, anatomy, fitness, sports and health.
Course Aims:
- Explain how energy is used in the human body to create work and power.
- Explain energy pathways during resting, work and recovery.
- Explain the significance of the acid-base balance in the body.
- Explain movement of materials in and out of living cells.
- Explain the affect of changing atmospheric pressure on the body.
- Explain temperature regulation in the body.
- Explain ergogenic aids to body performance during activity/exercise.
