I qualified to take part in a study at TCU that is measuring the impact of sprint intervals on endurance performance in trained cyclists. To qualify for the study I needed a VO2 max of at least 55 ml/kg/min. – I got a 61.2.
So yesterday was my first official “test” as part of the study. I performed the same VO2 max test I did last time; however, this time I would have a catheter in my arm and they would do blood draws every 2-3 minutes to measure my pH and lactate levels. I asked what the highest VO2 max they had so far:
“You’re up there. I think our top participant had a 62.2″
That gave my competitive nature something to shoot for. Someone once told me if there are 2 or more bikes on the road – then you have a race. It’s true – every “ride” has several mini-races or competitions . . . competitive spirit just takes over.
This test started pretty good since I was now a little more comfortable with the mask and breathing piece. When I got to the point where I blew-up last time (390 watts) I forced myself to keep pushing just a little longer. The results turned out pretty good – I scored a 64.7 ml/kg/min. I haven’t been able to race this season due to family and work conflicts, so it felt good to get the competitive juices flowing (even if it was against an imaginay opponent on a stationary bike). Funny, I always find that I’m most “at peace” when I have healthy competitive challenges/goals at work and physically/athletically.

That’s a 55lb. flywheel in back, and about as close as you can get to the true feel of cycling
Tonight I go back for the 2nd day of my first test block. Tonight’s test will be a 25K time trial on the Velotron stationary bike. I’ll be really interested to see where my numbers come out (specifically threshold power in watts) since I sold my PowerTap a couple months ago and haven’t performed a threshold test in 2009.
