Today I was able to head to Northeastern University for another VO2 max test. I had an odd calmness about me as I entered the Behrakis Health Sciences Center. Having completed a test just a month before I knew what to expect this time around and it helped a great deal in helping me relax. After meeting the doctor and students that would be running the test I tested my blood sugar and was happy to see 157. Diabetes wise I was all set the test could now start, as I sat on the bike I was very happy that the breathing apparatus they attached to my head allowed me to breath out my nose and mouth. As the test began I was to sit on the bike and relax for two minutes before the test officially began. The last time I was told to relax before the test my heart rate was around 90, today I was more relaxed and it showed instantly my heart rate was around 75. As the test began I was quickly able to get in to my cycling frame of mind, I focused on a mark on the wall ahead of me and let the legs do the work. The wattage would be increased every two minutes, I would know when the change was approaching but did not know what the wattage was at. That proved to be very bad. For the first eight minutes it was smooth cycling, the legs were working and my breaths were controlled. From the eight to ten minute mark the change in wattage was taking its toll. I had gone from feeling strong to feeling like I was giving it all I had. I was able to make it to the next stage, the pain I felt is something that I only expected to feel in a race. For two minutes it was as if I was trying to sprint up a mountain side in the toughest gear possible. My legs were burning, I was having trouble breathing and in a zone where I was going all out but had no real sense of my surroundings. It would take one of the students grabbing my arm as the test ended to get me out of my zone. I stopped pedaling and was able to catch my breath, took a huge swig of Gatorade and came back to “normal”. As we went over the results I was happy to see that my VO2 max had gone up from 55 to 57. Although the test was very painful I was able to push myself a little bit further. My blood sugar had stayed around 140 for the test, I would spike to 280 an hour after the test. I took a correction bolus and was back to my normal range a couple hours later.
Going in to the spring and getting in to the heart of my riding season I’m very happy that I have the information I have from both tests. It will do nothing but help me improve on the bike and with that who knows where the bike and my diabetes will take me next.
