Sledging (with partial statistics)

Something fouled up with my HRM so my first two rounds of sledging weren’t counted. Still, a good workout.

The problem was not enough conductivty on the sensors — it’s a chest strap that measures heart rate by detecting the electrical impulses of the pacemaker nerves. How sweet is that? Anyway, it means I have to “moisten” the sensors before exercising and sweat takes care of the rest.

I did 5 intervals starting with the 6lb and alternating to the 8lb. I added a set to see if it bumped my heart rate much more into the next zone… it didn’t. Just means an extra set at the same cardio zone which is great. I’ll discuss heart rate zones later and you’ll see why.

Each interval was a few seconds short of 5 minutes (except the last 8 lb one which bloomed out to 5:18). Average heart rate was good for the last three rounds: 130, 139, 141s. The heart rate graphs for my exercises show a definte drop off at about 3 minutes into the set then they spike back up. I have a feeling I know which exercise that is. I may rearrange the exercises to keep my heart rate more constant and put the low numbered movements at the beginning or end or half and half or something. I want to see a nice plateau or climb, not an M shape.

What’s funny is I don’t have a separate device to do GPS and heart rate, so whenever I pull all the data into the computer I see a little map of how far I went. This is great when I’m walking or biking or whatever outside, but sledging is indoors! I do everything from the same position in the living room of my house, so it’s funny when the map shows me traveling 75 feet. I guess that’s just the drift of the GPS satellites. There may be a stationary mode where it ignores the GPS coordinates, but it’s easier to just ignore the map.
