Running and Pain

After more than 16 years of inactivity I’ve finally decided to do something about my health!

I’ve started running (or jogging – read more about the putative differences between running and jogging). I’m following a strict schedule with the intention to -eventually- train for triathlon :-O … you know what they say:

Shoot for the moon. Even if you miss you’ll land among the stars.

I know… it’s really, really cheesy.

Mapping the pain on my body

I always find a good excuse for practicing my data visualization skills. So, here is a body map (the body shape was obtained from pinpointing , day by day, all the pain I’ve “suffered” during the initial days of training.

The number of points roughly corresponds to pain intensity and extension (i.e. more points = more pain over larger area).

During the first three days, I felt increasingly sore, but  in the morning of day 4 I felt something was changing in my body  – not only I started to feel less pain but also I felt the oxygen filling my lungs, I needed to ramp up the training!

At this point (i.e. at the very beginning of my training) I feel like there is more room for improvement and most of the pain is gone (see day 7 and 8). I definitely feel positive!

You may have noticed that there are no Y axes. This wasn’t a mistake: I’m simply too embarrassed to show my training schedule at this point 🙂

Day-by-day, all my pain



Body map: how-to

Two main softwares have been used for producing this visualization: FIJI (ImageJ) and R.

FIJI was used for pinpointing the pain on my body parts:

[1] Open the image of the body and

FIJI’s multi-point tool

[2] select the multipoint tool (add to the ROI manager) and click on the image. In the ROI list you’ll get the coordinates of the points.


R was then used to open the PNG file of the body shape and map the points using the coordinates obtained with FIJI.
