Energy Systems of the Human Body DVD

The human body's three energy systems for GCSE/AS/A2

Energy Systems of the Human Body DVD is a fast-moving and lively exploration of the human body's three energy systems:

• ATP-PC
• lactic
• aerobic.

It shows how they function together to supply the body's energy.

The programme deals in turn with the following topics:

• Inside our muscles - voluntary and involuntary muscles, muscle fibre and myofibrils, myosin and actin filaments, how ATP releases energy, cross-bridges, fast-twitch and slow-twitch fibres
• The anaerobic energy systems - basic chemistry of the ATP-PC system and the lactic acid system (anaerobic glycolysis) used in the early stages of physical activity
• The aerobic energy system - how aerobic glycolysis synthesizes ATP from glycogen to provide the dominant energy source after 30 seconds of intense activity
• The energy systems working together - how the three energy systems contribute varying proportions of energy at different stages of physical activity; VO2 max as a measure of aerobic fitness
• Fatigue and recovery - difference between local and central fatigue; reaching the lactate threshold, the importance of adequate rest and recovery.

It comes complete with a teachers' guide and photocopiable diagram sheets. A great resource for you to use with your students taking the public examinations.
