Above the VAM zone, the only way to raise the
intensity is to increase the anaerobic energy production. We talk about anaerobic
power and capacity. This 2 zones are not measurable by VO2 or heart rate, the
only usual controller is the lactate production.
Here we difference this two new zones. The anaerobic
capacity is the skill to keep up a long time anaerobic effort. This efforts are
usually without resting. This is why it’s considerate a glycolytic way to
obtain the energy and not by the phosphagen system. Nonetheless, there are
times when a mix of this main ways to gain energy are possible (when starting
and stopping over and over again).
This zone is not measurable if you have not a
pre test where the VAM and the other less intense zones are described. Because
the only way to mark the anaerobic capacity is by % of VAM.
During race, anaerobic capacity is needed when
the event requires you to increase the pace constantly over the VAM. This means
that just until 5k races (as maximum) you may need to develop this on running.
It’s specially important on 1,5k races.
In 2009, an article studied the anaerobic
reserve on 800m and 1500m with middle level runners. It seems to be a relates a
not fast start on 1500m with a better anaerobic reserve and a better result in
the competition. Instead of this, running 800m, seems not to be related with anaerobic
reserves, but it does with the total oxygen deficit the athlete is capable to
endure.
Here I let you the article.
We’ll continue with anaerobic skills next post!
