Below is a list of links to eight animated examples
of energy metabolism that are on The Secrets of Lactate CD-ROM.
These require Flash to run properly and may not run on some older
browsers. In this demonstration only one link is active, that for
the step or graded exercise test. Each example shows how different
metabolic parameters behave during different types of exercise.
These examples mainly involve running and rowing. They show steady
state as well as the exhaustive type of exercise that is typical
during short races (20 seconds to 6 minutes). They are from the
writings of Alois Mader who has in the last 15 years been developing
a comprehensive model of energy metabolism. You will notice that
some of the examples are from 2003 but some are from 1988.
Press the link in the table below for the step test
and it will take you to the example. A text box will appear at the
bottom of the window with instructions. All the examples work more
or less in the same way. Namely, you press the button next to the
physiological parameter of interest and a curve will appear in the
graph window indicating what happens to that variable during the
exercise. A "Clear" button removes the curve when you
wish. In some cases there is more than one button to press for a
variable because there are curves for more than one athlete within
When you are finished, click the brown return box
titled "Home Page" in the lower right corner and you will
be brought back to this menu. To get back to the CD-ROM menu from
this page click on the logo above or the link below.
These are meant to be educational in nature and
any suggestions for improving the presentation format or the material
covered are welcome. We hope to add examples from other sports to
these animations in the future.
