Spreadsheets as Diary

It occurs to me that there is much to be said for using a spreadsheet for a diary.
1. Formulas help:
A. Restrict entry types for easier categorization and post analysis.
B. Reset event accumulations as in "how long has it been since" or "it's time to do this".
C. Use "now()" to reverse track event duration statistics.
2. Recent entries can use formulas but when archived to another sheet paste special value to save more robustly.

The sauna and the workout

Post in progress...
  1. My body's reaction to the sauna isn't stable. Usually I climb in with it at 60 °C and stay in for 25 minutes until my heart rate is near 100 bpm and I'm drenching. Occasionally though there have been times when this exposure was unbearable and I had to crack open the door to survive. Clearly somehthing else is going on.
  2. The heaters are thermostatically controlled by interior air temperature. My body is heated, however, by radiant energy and not by air convection. So the thermostatic control doesn't do a good job regulating heat transfer to me. When the thermostat turns off the radiant heat decays out and there is a significant reduction in how hot the sauna feels. In other words there is a perceptual undershoot. I think a new control strategy is warranted.
    1. Use the temperature of a simulated person mass instead of air temperature to control the air
    2. Use a simple switch to control the heaters
    3. Replace the thermostatic control with a timer alone. <--My plan at the moment
  3. I want to explicitly mention how important my heart rate is while I'm using the sauna. It came as a surprise to me that it was so valuable. It allows me to get a good feeling about the stress I'm being exposed to even when the conditions of the stress are hard to determine. The variables that determine stress are:
    1. Exposure time, Energy absorbed, Body hydration reserve, Fatigue?, Air temperature, Body heat absorption characteristics? (what are they?), clothing, 
    2. Hmmm. I am seriously out of my depth here. And I think I know some people who actually know this stuff. Maybe I can even find some serious research online.
  4. Here are some other sauna workout references.

    My Evolving Exercise Diary - Version 1.01

    I cleaned up My Evolving Exercise Diary a little bit on Google Docs this morning. The only significant thing I did was to eliminate the need to sort the SH Key in the Entry Types sheet and I got rid of the SH Key check column in the Diary sheet itself. It's such a small evolving change. (It's shared to view so you must save it before you can edit it.) There are introduction and help sheets with it and even previous posts that describe it more.

    My Evolving Exercise Diary can be used as it is by replacing the sample data with your own diary events. For those already using it though upgrading is not a painless process. Since spreadsheets combine data with formulas, upgrades need to add in the user information from the old diary without overwriting the new formulas. Here's how to go about it:
    1. Save the new Google Docs spreadsheet so you can edit it.
    2. In the Entry Types sheet: Cut and paste to match your old version. (It's all data and no formulas.)
    3. In the Diary sheet:
      1. Make new rows or delete some so that the number of rows in the new diary match the old.
        (Do not copy rows from the old diary into the new diary! You must copy rows from the new diary and paste them into the new diary. There are formulas in the rows and they need to be the new formulas.)
      2. Copy the SH Key column from the old diary into the new one.
      3. Copy all the green user input columns one at a time except for the Training Cycles column from the old diary to the new diary. (There were no changes to the formulas or the data in the Training Cycles column. I just changed it to blue.)
    Alternatively, you could figure out what changes were made and make them yourself in your old diary. (Hint: Each VLOOKUP function has a new additional parameter ", false".)

    If anyone is using this I sure would appreciate a comment. I think it has a certain elegance missing in other workout spreadsheets.

      Adding an infrared sauna to my program

      I just bought a far infrared sauna and of course it offers a whole new set of considerations about how to use it and integrate it into my intermittently flagging exercise program.

      First, here's what it looks like. You'll have to imagine the pervasive cedar scent.

      I'm satisfied that the better quality infrared saunas are safe. They emit the same kind of radiant energy that is produced by things like campfire embers, warm rocks, human bodies and cute little kitty cats.

      As a note, I think it's strangely counterproductive the way that sauna brochures describe infrared as being between microwaves and ultraviolet-B. I wonder why they don't also relate it to cosmic rays, x-rays, microwaves and particle beam accelerators?

      On the other hand, the time and temperature exposure levels that the saunas provide is a legitimate concern. Both traditional saunas and infrared saunas can provide an extreme environment and they must be used carefully.

      I don't have any strong feelings about the health benefits of infrared saunas. I'm pretty skeptical about all the claims. I bought mine for purely creature comfort reasons. If any health benefits come along that would be nice too. It is, however, both a physical an emotional benefit to relax in total warmth when those cold winter days start coming around. Just knowing it is there with it's wonderful cedar scent always offering comfort and (can I use the word "warmth" again) is enough to get me through the day.

      Then comes the question about how to use the sauna and I have questions with few answers.
      1. Should I use the sauna before or after a workout? Browsing around the web I see that most people seem to use it after a workout. I suppose their intent is to help the recovery process. But I'm thinking that warming those muscles and joints up before beginning my exercise might be a better way to go. Maybe first a little sauna with some stretching, then smoothly into a cardio session finally followed by a strength training workout. It's rather appealing to me. And I sometimes need some incentive to get out of bed and get started on those chilly early mornings.
      2. My sauna temperature control does not seem to control air temperature. Since the heating effect is mostly due to radiant energy and less due to air convection this makes sense, but I don't know how they calibrate it. What is that little sensor really measuring? Is it some kind of material that is sensitive to radiant energy? Does it have a real significant mass to provide control damping when the heater cycles or is it a virtual heat load of some kind? 
      3. I want to start using my heart rate monitor while I'm in there and measure my water weight loss. Today I noticed that my heart rate went from 60 to 93 in 25 minutes as the temperature built up from 126 to 150 degrees F. I was impressed with how smoothly heart rate increased. 
      4. Of course the sauna exposures fit right in to the Google docs workout diary.

        My Evolving Exercise Diary - Continued

        This is an addendum to an earlier post. This is a little more technical and includes a link to a sample Excel file.
        [Update: A more recent Google Docs link is available in a later post.]

        To review, I wanted a simple flexible method exercise diary that can:
        1. Track my exercises and related information in sequence as they were performed
        2. Provide user definable entry types for different kinds of information
        3. Allow later analysis
        4. Be online, easy-to-use and free
        So I came up with a diary using a Google Docs spreadsheet .


        Be aware that you have to be a bit geeky to use it. The purple column on "The Diary" is an index into the "Entry Type" sheet. Green cells are for user data, blue cells contain formulas. You create a new entry by copying an existing row with its formulas into a new row, then enter data into the green cells.

        A simple "one sheet" approach would have propagated columns endlessly so instead I emulated a key indexed database so that each column represents a different type of information depending on the "Entry Type" index. This approach allows the user to add, delete or change the types of information in the columns for that type by editing the "Entry Types" sheet. There is a help sheet and if you're not familiar with the technique you may find many other uses for it.

        Here's an image of a sample "Entry Types" sheet.


        [Update: I removed the comment about not being able to distribute this directly from Google Docs.]

        Finally, I appreciate comments.

        Using the rack for calf lifts

        I'm still adjusting the power rack configuration for my calf exercise. Here's what I'm doing now.

        The basic idea of the lift is to have the bar on my shoulders with my toes supported on the top of of a 4 x 4 inch block with my heels unsupported. I then raise and lower my heels using calves alone.

        The rack is setup so the bar rests on the crossbeam below the bottom of the lift. The bar slides up and down the side of two 2 x 4 inch pine blocks located on each crossbeam as shown in the figure. Using the block avoids irritiating bumps that would otherwise be caused when the bar hits the top of the beam slider.
