In the last blog I talked about how and why altitude affects endurance exercise but would altitude also affect short explosive exercise where oxygen is not a factor? Well, let us find out.
Most of you have probably heard that when we exercise we can use two systems: Aerobic and Anaerobic. Aerobic means that we need oxygen to produce energy and any event that last more than 60″ seconds is basically going to depend on that system for energy. Anaerobic, on the other hand, means we are able to produce energy without oxygen and any event that last 10″or less seconds is going to use mostly the anaerobic system.
So, would altitude affect anaerobic exercise? We know now ( thanks to the last blog) that the partial pressure of oxygen is lower at higher altitudes but since we would be doing an activity that does not require oxygen that would not affect us. We also learned that at higher altitudes there is a lower air density. If there is a lower air density it means there is less resistance, meaning your running speed could improve!!
There you have it, since anaerobic exercise does not rely on oxygen and there is less air density, any exercise that does not last too long should not be influenced by altitude. And that is what happened exactly at the Olympic games of Mexico city in 1968. In most of the short duration-explosive events there was a big improvement!
Hope you enjoyed it.
