First on the list was a Personal Profile. This included measurements of height, weight, calculated BMI from those two, estimated cardiovascular max VO2 (based on heart rate reading from a treadmill run and recovery), bicep strength, stretch and reach flexibility, and body fat (via calipers). A computer program then took all of the data and gave me a rating of my overall fitness and "body age". In short, the tests showed that I'm in the "normal" category for BMI, have an estimated "moderate" VO2 Peak (how that's possible with all my workouts I don't know!), average bicep strength, average hamstring flexibility (not surprising since I'm a runner... it makes legs pretty tight), "optimal" body fat composition, "good" overall fitness, and have a body age a few years younger than my actual age. I'd have to say that while this data was interesting, it was pretty generic and didn't give me much guidance. It pointed out things that needed improving but not really any information on how to best proceed in order to see the results I wanted. I knew I needed more scientific data. On to test two...
Test two was called CaloriePoint, and was a metabolic test that calculated how many calories my body burns at rest. I had to fast for 12 hours (brutal for me not to eat first thing in the morning!) and avoid caffeine for 24 hours prior to the test (no problem). Basically I was strapped in to a heart rate monitor and placed in a dark quiet room for 15 minutes while I breathed in to a tube. That tube was connected to a computer which then analyzed the air I exhaled. While this was about as simple a test as one could hope for, the results were very detailed. It showed that if I were to sit on my rear and do nothing all day, I would still need to take in 1324 calories to sustain my basic physical needs (heart beating, blood pumping, food digesting, etc.). If I were to factor in my average daily activity (the amount I walk around, etc.) then I now need 1854 calories. And then, on top of that, if I workout then I also have those calories to eat too. Eating too few calories can be as detrimental as eating too many, so THIS information was very helpful to me and could definitely be used to reach one of my goals (lean out a little bit by dropping 6-8% body fat). Although I'm already in the "optimal" range of body composition, I'm at the higher end of the range and would like to lower it down; being in this range also means that I don't have a ton of calories that can be eliminated every day so I'm looking at losing only 1/2-1 pound a week, if I'm lucky. So for now I'm shooting for around 1500 calories a day, not including exercise calories (I happily eat those calories guilt-free!).
Test number three was called CardioPoint, which I also call the Hannibal Lecter test. I was strapped in to a breathing mask that was entirely uncomfortable and slightly unnerving.
Not me running (obviously), but this was the getup I was in.They started me at a pace that I felt I could sustain without problem for 30 minutes and then, after a 3 minute warm-up at that pace, things started to get interesting. Every 30-60 seconds the incline would be raised a couple percentages in order to make it more difficult. I was told that I had to last at least 8 minutes for the test to be valid and that once I hit a 100% (of what measurement I can't remember) then I'd be allowed to stop. Let's just say that by the seventh minute I was really working hard and I was just hoping that the 100% would hold off 60 seconds longer! Thankfully I crossed the 8-minute mark and then a minute or so later I was given the okay to stop. It's a good thing because I had reached the point of effort where the desire to puke was very strong and I don't think I could have gone on even 30 seconds longer without losing it. I know that's a normal bodily response at that level of effort but hey, it's still not pleasant to go through! However, once again, the effort was worth it. I now have heart rate zones that are specific to me, know how many calories I burn in each zone per minute, and what percentage of those calories are from fat vs. glucose. No more generic "220 - age" numbers or hoping that I'm working my body at the right level to achieve my goal for that workout. In fact, a comparison will show what a difference there is:
Generic Zone
1: 92-110
2: 111-128
3: 129-146
4: 147-165
5: 166-183
Personalized Zone
1: 128-137
2: 138-144
3: 145-151
4: 152-161
5: 162-172
So, as you can see, there is quite a difference. The generic vs. exact has enough discrepancies so that it could successfully derail my training; I might think that I was training my AT (aerobic threshold) when really I was still in base building, and I might think I was doing base building when in essence I wouldn't be working hard enough to have any real benefit at all! Throw in there that I need to spend most of my time in zone 1-2 in order to best achieve my other goal (dropping body fat) and I might have REALLY been frustrated.
Finally, going back to my Estimated VO2 Peak from the first test (the one that had me at a "moderate" rating with 35.4 ml/kg/min)... My actual, scientifically tested VO2 Peak is 47.1 ml/kg/min, which falls in to the elite (best) category. Right on :)
