Wondering About Heat Dissipation

Posted by Kevin Doak on Friday at: 8:45am (September 5th, 2008)
I just went for a quick run. Let me just get this out of the way right now... I'm not a strong runner by any means. I've never understood why, but on average, swimmers are not good runners. Now that we have that cleared up, I'm proud of my run tonight. Lately I've been running with an MP3 player. I run for the length of a full song, then walk for 30 seconds. Since my body isn't used to the impact of running I'm trying to ease into it. Tonight I ran twice around my neighborhood which I've clocked at about 3/4 of a mile. So although it's not a monumental achievement of mankind, a 1.5 mile run is a step in the right direction for my 5k later this month.

I know I need to work on a few things before my race. I need to stay conscious of my distance per stride. Like anything else, when I get tired my stride shortens and I get slower. Tonight I noticed that my left knee got sore around the 1 mile mark. It wasn't too painful so I ran through it. The pain mostly went away during the next quarter mile.

As I was running I thought of a topic I'll do some research on. I notice that I barely ever sweat. I was running a mile and half and never broke a sweat. I know for a fact that I was working. I was carefully pacing myself because this is one of my first runs of any distance, and it was a fairly cool morning, but it reminded me of all the other times I noticed the same thing. This realization could mean a few things:

A. I'm not working hard enough to sweat.
B. My body dissipates heat well and I just don't sweat as much as other people.
C. My body isn't hydrated enough.
D. I have a higher than average aerobic capacity and it takes more to break a sweat.

After considering a few options I'm reminded of all the times I've worked out with other people and they're dripping with sweat and I'm not. I remember sitting at a Tigers game with Kara Lynn Joyce, a friend and 2 time Olympian and she was sweating a lot just like everybody else sitting in the sun. I was sitting right next to her and was totally dry. I remember it confusing me because we obviously have an incredible swimmer here, one that is MUCH much better comparatively than I and it seems like she's working harder to just sit there. I'm not convinced it's a competitive advantage, but I do wonder what it means. I think it's obvious that I'm not informed on this subject at all so therefore I'm going to do some research and report back for my own benefit. Thanks for reading.
