VO2 test – cycling

Later this week we will start the formal part of the research. Today, we did a VO2 max test on bicycle to gauge my physical fitness. They were pleased last week by my low resting heart rate (42). The setup for test is, you wear a heart rate monitor on your chest, have a nose clips on your nose and breath through a tube hocked up to a machine providing air that analysis your oxygen to carbon dioxide concentration. It also measure things like the number of breaths per minute and a boat load of other measures. Once you are hooked up to the gear you start cycling for two minutes at a certain resistance (measured in watts) and then they increase the resistance by 40 watts. Each stage is two minutes long and the resistance is raised by 40 watts. The starting resistance was 40 watts. I was able to hold on for six stages before I shut down. My calfs and quads were burning by this point. The researchers decided to stop it as I was ready to go to the next stage. In the end, I have a VO2 rating of 50 which is a little lower than my running VO2 which means that I am in good shape.
