Physiology Experiment: Demonstrate the how the aerobic energy system provides energy to fuel our muscles when we exercise. Check out the links at the end of this post for the full experiment details!
The heart contracts in a constant rhythm (the heart beat) that may speed up or slow down depending on the need for blood (and oxygen) in the various body tissues. For example, if you start running, your leg muscles will need more oxygen to do the work of running. Therefore your heart will have to pump more oxygen-carrying blood to those working muscles, and so have to beat more rapidly in order to supply that blood. In today's post we will show you how hard the heart is working during exercise.
We placed heart rate monitors and GPS units on the Youth Ambassadors today as they ran 40km across the edge of the Salar and then up into the Altiplano where Volcanoes surround us. The heart rate profile from the run is available below and explained in more detail on the experiment report and results page.
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.
