I doubt Greg LeMond aggrees with alot of what's there since there are errors and false statements in
virtually every section.
For example...
"1. Maximum effort (sprints): This effort lasts 10 to 25 seconds.
- It is similar to a 200 meter sprint.
- It calls for 100 percent of your maximum heartbeat."
Your HR will not get to 100% in only 25 seconds.
"2. Submaximum effort (pure anaerobic interval): This effort lasts 25 seconds to two minutes.
- It is similar to a one-kilometer time trial on the track.
- Your body is operating at very nearly 100 percent of your maximum heartbeat.
- It is considered the purely anaerobic interval."
Many kilo riders will not hit their MHR and it is well-documented that 20-40% of the energy utilized
during a kilo is aerobic, not 0% as stated. It's even more aerobic for a 2-minute interval.
"4. Average intensity (anaerobic threshold): This exercise lasts from four to 30 minutes.
- It is similar to a five to 20 kilometer individual time trial.
- Your heart rate is between 90 and 100 percent of its maximum.
- In this exercise the body uses aerobic oxidation (oxygen provided through the bloodstream) because
it is not in an anaerobic state."
I doubt that anyone can go to 100% of MHR when they are "not in an anaerobic state." Even 90% of MHR
and completely aerobic would be most unusual.
"5. Light intensity (intense aerobic): This exercise lasts 30 minutes or more.
- This exercise is similar to a 25 mile time trial up to a long-distance but intense effort.
- Your heart rate is at 80 to 90 percent of its maximum during this exercise.
- Your body is in an exclusively aerobic state.
- Your body will first burn the glycogen it has stored. After that you will be running off fatty
acids. This is the bonks (complete exhaustion).
You don't burn glycogen and THEN fatty acids at this intensity. You burn them both simultaneously.
If you run out of glycogen you'll burn fatty acids but also protein (from muscle tissue). And the
"bonks" is not complete exhaustion.
It sounds like this was all translated from another laguage by someone who was a "personal trainer"
at a local gym.
