I think we will see a further major proliferation of products for folks to measure and track and share this type of information. Some of the companies are enjoying rapid growth. Take a look at Fitbit for example... just the posted jobs available gives one some idea of what is going on. I have direct contacts into many of these businesses and I believe it is going to be a very crowded space.

I hope that folks realize what these tools are and what they are not.

I think of the body as an energy system. I am personally striving to achieve a balance between a focus on energy out (amount, quality, frequency of activity/exercise), and energy in.

I find that the quality and quantity of beneficial exercise/exertion, what have you, resulting from a weekend of racing and or track driving are not very high.

My first patient this morning was a 77 year old competitive runner. He has run the Boston marathon 5 times. He looked amazing-way younger than 77.

I have basically eliminated chronic back pain by getting serious about stretching

Another comment on cardio from personal experience. Before I started a lot of cardio my resting HR was in the 90s. It is now typically under 60. Definitely an advantage for driving at the track and I'll probably live longer now (debatable as to whether or not that's a good thing!).

Things wrong with this device:
1. It will readily fall off your wrist unless you secure the clasp with an "O" ring. I am on my second Fit Bit Force….
2. The Force is easily tricked by vibration. I wore mine on the track and experience bogus #'s…it said I did 15,000 steps that day, no way I could have. I drove my ATX around El Rancho for a few hours, another bogus reading.
3. It not so accurate in counting stairs climbed.

Things right with this device: It appears to be accurate on a treadmill as well as an elliptical exercise machine. And it really works well when walking around. I must like it because I have gone from the FiT Bit clip on device, to the Force, lost the first Force (No "O" ring), and am on my second.

The wireless interface to my Mac is pretty cool too. The Force also does sleep monitoring.

Interesting thread. I have a Polar FT80 that I use when I work out, and I was also curious about workload when racing, so I wore it at Sebring a couple of weeks ago. Here is the data from my heart rate monitor:

Sprint 2: Duration: 00:41:16, HR Avg: 144, HR Max: 174, Calories: 512 Cal, Training Load: 117
Enduro (until my control arm broke and I DNF'd): Duration: 01:49:40, HR Avg: 135, HR Max: 172, Calories: 1237 Cal, Training Load: 256

See the heart rate Avg: and Max: below. I don't know if my heart can beat that rapidly!!!! If I use the 220 - age, I may have already flat lined. My resting pulse is about 55, so maybe that's why I am still here…and I ran 3 races last weekend, 2nd place on Saturday, two 1st places on Sunday. But they were only 20 minute sprints…maybe that's why I am still alive and kicking. Perhaps a 1 hour Enduro would literally be the death of me

That's me in #10, last December, beating up on some low HP cars at Willow Springs, someone has to do it?

won 2 races last weekend, albeit 20 minute sprints!!!

Here's another view of the data. It clearly appears that I flatlined several times too ;-). I'm 53, and my resting heart rate is about 60. You can see that on the grid, I'm not at rest, and you can see the time spent winding down in the pits after the break.
