Where Do We Get All That Energy. Exercise physiology is
essentially two concepts: the DELIVERY of oxygen to the working
muscles and the USE the delivered oxygen (I’ve just summarized
eight years of college). Everything else simply supports the
delivery and use of oxygen. I personally think coaching books
either go too far into physiology and biochemistry or just
ignore it altogether. I’ll be gentle in my discussion in this
four-part series. To deliver oxygen, it has to be carried and
most people remember from biology that oxygen is carried by
hemoglobin in red blood cells. Sure, there are details about how
oxygen is carried, but just understand that a red cell has only
so much space to carry oxygen and blood can only have so many
red cells before it becomes too thick. Want to carry more
oxygen? You need more red cells, thus the illegal attempts at
blood doping where a very specific protocol is used to remove,
store, then reinsert the red cells to increase oxygen carrying
capacity sometimes used by hard core e
