VO2

I had a VO2 Max test done this morning at UVM, as part of a GMBC group that was celebrating the grand opening of a new rehab / fitness center in town. The test takes about 1/2 hour with warmup, and the real work is only about 15 minutes long. I rode my bike in a Computrainer and I was breathing into a mouthpiece attached to a gas analyzer. My heart rate was recorded along with watts, speed, and cadence from the trainer. We calibrated a cadence and intial wattage reading while I warmed up, then as the test began the goal was to ride as close as possible to my selected “ideal” cadence as possible, as resistance was increased every 2 minutes. It started to hurt when I hit the middle of the 300 watts section – about 5-7 minutes into the test. I’m not sure how far into the resistance we reached nearing the 11 minute mark – I had tapped out all my gears, was pedaling squares, and was struggling to breathe. The techs gave me a preliminary data sheet – the last 2:40 of the test I was riding a consistent heart rate of 193 bpm! At this point there are only a few numbers that I can make sense of – I’m looking forward to a detailed evaluation of my test results that I should have later this week. Jen snapped a few pictures – neither of which are very flattering – but I do like the fish look as I reached for my waterbottle.

    Wow
    I’m looking into this – tomorrow I see the person for initial evaluation. Be sure to post the results – 193 ugh

    Amy,

    The test was very enlightening – even at this early stage of not having a translation of the raw data. All winter I’ve felt like I’ve been training “too low” in my HR range. I think my prolonged effort at 193 reinforces that feeling – and I’m curious to see what the doc sends over as my new training zones. I’m also curious how I improve throughout the season – I’m heavier and feel slower than I was at the end of last season – and I hope to re-test mid to late spring and see if my training is effective.

    While I’m not a racer – I do appreciate making the most of the time I spend working hard and “training”. There always seem to be plenty of rides where I just enjoy the day and take in the scenery, and not enough of the ones where I focus on speed work or climbing. I’ll update the blog when I get the next batch of data, as well as if I feel if the test was worth it as a training tool.

    If you can, you might explore getting a group rate on the test. Our local club put together 6 cyclists who were all tested during a few hours – this saved time – and the doc offered a half price discount to the group!

    Breathing into that tube is no fun at all and the lack of water is annoying! At least you got to use your own bike!
