This is a link to an extremely useful website for researching and revising both AS and A2 physiology. It contains up to date research on nearly all of the topics covered on the Sports Studies course and is a very useful re-cap for everything that you have covered in lessons. Well worth looking through.
Another great website for revision purposes. This link takes you straight to the section on the aerobic energy system but simply select 'Anatomy and Physiology' from the menu on the side and you will be able to access information for everything covered on the course. Again, well worth having a look through to re-cap key information.
