Experiment: Does Running in Cold Weather Make Me Burn More Calories? (Part 2)

I did a second test of my Running Cold Experiment last Saturday afternoon! Methodology was the same as Trial 1, with similar conditions, although about 8 degrees warmer.

Qualitative Data: Thoughts on Motivation and Level of Physical Fitness

I’m a bit ashamed to say that Trial 1 where I finished the mil at 11 minutes was one of my faster miles up to that point. Only a few times had I ever completed a full mile run without walking part of it.

BUT on Trial 1, my main motivation was that it was COLD. The run was very chilly at 35 degrees, which helped motivate me to push onward (and how!).

For Trial 2, it was still cold but not quite as bad, and this time my main motivation to push onward was that my brother joined me on the run, which always adds a bit of a competitive element. Although the time spent running on Trial 2 was 30 to 60 seconds shorter than Trial 1, Trial 2 felt less laborious.

After running Trial 1, I felt pretty sick for about 30 minutes afterward. This is probably because I hadn’t done much running in a long time! I recovered significantly faster and felt better after Trial 2, and was much less sore the next day, as compared with Trial 1.

I know this is not because of lowered output because I actually made better time on Trial 2. A possible explanation is that my endurance improved after the first Trial. It doesn’t seem like I should notice such a marked improvement so fast after just one run.

I don’t know what that might mean for the experiment though, because my physical condition is another factor that could potentially influence the MET and calorie measures I am tracking. In the future I will be adding Heart Rate to the metrics I track in the hope that I can use it to help control for physical fitness level.

Experiment: Does Running in Cold Weather Make Me Burn More Calories? (Part 1)

I just completed the first trial of my Running Cold experiment and have some preliminary results!

I had previously defined my plan for the experiment at the end of this post.

Weather/Temperature

Here’s the weather info for today, according to Google:

Cold Experiment Weather

Attire

For the run I wore a pair of running pants, tennis shoes, a black T-shirt, and a black ski hat to cover my ears (I get headaches if I’m in the cold with my ears uncovered). Once the weather gets warmer, I’ll stop wearing the hat, but other than that I’ll make sure my attire remains the same across trials.

4 Months of Calorie Burn: What Have I Learned So Far?

I now have over 4 months of BodyMedia calorie burn data:

Nov 2012 Daily Average: 2,205
Dec 2012 Daily Average: 2,123
Jan 2013 Daily Average: 2,183
Feb 2013 Daily Average: 2,114

The average seems to be going down. Why?

Is this the result of changing habits, a change in seasons, or just pure dumb luck?
