I recently took a fitness test that measured my VO2 Max, ventilatory values and lactate threshold. I went to a physiology lab at a college to take the test. Each test is sport specific, so I mimicked cross-country skiing when I did mine. I stood on a wide, sticky treadmill with ski poles. The physiologists strapped a large mask over my nose and mouth to measure my breathing and oxygen consumption. It covered so much of my face that it helped me feel more on my own, diminishing the extreme anxiety I felt being in a “test” environment. On the flip side it was hard to breathe and felt a little claustrophobic. They strapped a heart rate monitor to my chest. I wear my own monitor every day, so that was no big deal. In fact, the polar chest strap felt so comfortable that I forgot it was there. My own Wahoo strap has to be unpleasantly tight to stay on and I look forward to removing it the second I finish working out. As I started walking on the treadmill, they incrementally increased its elevation and speed. They pricked my finger every 3 minutes to measure the lactic acid in my blood. They had to keep increasing it more than they anticipated because my fitness was higher than they or I predicted.
It turns out my VO2 max is literally “off the chart” at 45.5 ml/kg/min. The chart above doesn’t have a top end, it just lists over 36.9 as superior for my age group. The chart the lab uses lists 39 to 42 as superior for my age group. Even though cardiovascular capacity decreases with age, I am still superior for any age! perused the internet a bit to learn more about these numbers, and immediately noted that every chart is a little bit different. Still, I rate as “superior” for all of them. Many sources cited that heavier weight decreases the calculation. I ate a gigantic resort omelet just before the test. Not sure if that was to blame, but I weighed in 9 pounds heavier than I do at home. Could it be that my “real” weight is less, making my “real” VO2 max even higher than the result? I also read that VO2 max decreases at altitude. Since I took the test at a significantly higher altitude than home, could it be that my “home” VO2 max is even higher still? This came to me as a massive confidence boost. Every stumble, every insult, every insignificance I felt onward from this test couldn’t dampen my spirit. Now I can simply say to myself, “well, sure I’m really bad at (fill in the blank), but I have a super high Vo2 max! For real!” This is cold, hard data, no one can disprove it.
This test also reminded me that you do improve whatever it is you put your heart into. Sure, cardiovascular health is really important to me. I started blood pressure medication as a teenager and nearly every relative I have survived a heart attack, died from a heart attack, or both. A deep drive to take out any smidge of “personal responsibility” out of any poor health conviction or disease I may have is a strong desire for me to eat and exercise responsibly. That that is just what got me going. The truth is I LOVE riding my bike. I LOVE skiing. I LOVE my boxing classes. It comes natural to spend many hours a week doing these activities. I put a lot of energy in my 20’s worrying about weight and image. My daily energy in the past decade has been more one of love, exploration, and accomplishment. I didn’t think about scoring my relative fitness once, I just did what I love and strived to be my best self. When I was younger, I LOVED drawing. I drew all the time. I probably spent as much time drawing in a day as I exercise now in a week. I got pretty good at it. I don’t draw much any more, so I am reminded that while interests change, it still matters to do what you love.
I need to acknowledge how much my life situation contributes to my fitness. I demand jobs with easy commutes. I never lasted long in any job with a drive. I had the luxury to choose jobs that meet this quirky requirement that I seem to be alone in demanding. I am incredibly lucky that I found a job and a home with an easy commute that I can do almost every day. I have a stable job that pays enough to supply me with quality gear that keeps me comfortable when I’m riding. I have a relaxed enough job that I am not too tired to exercise outside of work. I have a relaxed enough boss that it’s ok for me to start about 10 minutes later than my official start time to allow time to get dressed after my gym class ends (I make up for the lost time at the end of the day). I spent a few years going through different gyms. I just lucked out with this one. A work friend mentioned she went there, and it just hit me that I should try it too (this is a pun because it’s a boxing gym). The gym really took my fitness to the next level. I’ve always had strong thighs, ever since I played soccer in high school. I had strong arms and lats before from lifting weights. Biking gave me cut calves. But I never, ever had a strong core. The boxing gym, Title Boxing Club, gave me visible obliques and shoulder muscles.
I spent a lot of time feeling like I’m at my best, at my peak, this year. It’s a wonderful feeling. Every day, every moment, I am thankful for the gifts that help me feel this way; health, good fortune, and not having the setbacks of injury or collusion when out on the road.
