Science Of The Run: Adaptation

Physiology Experiment: Highlight how the body's breathing control system changes in low oxygen and how we respond to exercise. Check out the links at the end of this post for the full experiment details!

The final day of the run across the Bolivian altiplano provided some of the best scenery of the entire trip. It also provided us with some very interesting physiological data. We have been talking about oxygen saturation throughout the trip, as we are at high elevations and therefore getting oxygen into our systems is constantly on our minds.

The run finished at the highest elevation of the entire trip 4200 meters! The Youth Ambassadors have adapted so much that they were able to finish with a strong run despite having the lowest oxygen concentrations in their bodies that they had yet experienced. Below is the latest O2 saturation graph with the new data points on the right side of the graph. We were fortunate that our local guides who live at 3800 meters elevation agreed to participate in the testing as well! For more details on the experiment, visitthe full report and results page.

» Dr. Wells' Science Of The Run

A complex series of metabolic pathways are present in human muscles that break down food to produce energy for different types of muscular activity. Dr. Greg Wells will perform experiments to highlight how our bodies work in high altitude and during long distance endurance running.
