Burning Fat in Winter Workouts

Friday, January 29th, 2010

I researched a great tip to pass on to your clients:

The age-old question is, ‘Do we burn more fat exercising outdoors in colder weather or in hotter weather?’ I have heard professionals banter back and forth on this issue for as long as I been a gym rat. During this brutal Midwestern winter I decided to do some research on this and I gave up with the definitive answer. I found the definitive study on this in the journal, Sports Medicine 1991 issue. The study was conducted at the Naval Medical Research Institute. They found that fat metabolism was actually slowed down in cold weather. They hypothesized that the slow down in metabolism could be linked to the constriction of blood vessels in the peripheral fatty tissues when exercise is done in the cold. The study also found interesting results on breathing outside. (Don’t we all feel that are breathing is so much deeper and cleaner when we run in the cold weather?) They found that indeed, upon initial contact with cold weather the volume of air inhaled and exhaled in the first minute is higher but soon after continuing to exercise (run) in the cold it returns to rates comparable to what it is when we exercise (run) in warm weather. (Hmmmmm……) They also found that heart rate is generally lower in cold weather exercise.

This is great information to pass onto clients at all levels when they ask this question of you. Now you have the definitive response and the research to cite. Run with it. (Excuse the pun.)

I Feel Badly

While taking a run this morning on the Chicago lakefront I did something I feel badly about. As I was well into my run my mouth developed a good deal of saliva as we men are often known to do. I looked behind me to my left and then to my right to see if another runner or cyclist was approaching me from behind because clearly there was no one approaching me. I prepared that mouthful of spittle, took a deep breath and off it went out of my mouth and on its way toward helping the lakefront grass to some nutrients. But, alas, from out of nowhere a cyclist going at an estimated speed approaching Contador and Armstrong dueling down a French mountain, came next to me at the moment of launch and my well intended lawn additive landed squarely in this cyclist’s face. After a string of choice words and a bit of a wobble on his expensive road bike he didn’t break pace and sped off.

My first reaction to this unfortunate incident was, “Oooops! I feel so bad, sorry good sir.” But, as I jogged on my merry way also not breaking stride from my blistering 10.0 mph pace I thought about how many times I had seen cyclists speed by runners, walkers, groups on this same path thinking they are re-creating a stage of the TOUR and ride up upon people without warning. I have seen cyclists run right into the backside of runners, I have seen runners change lanes suddenly and bikers swerve to avoid a crash only to be thrown violently from their bike. All of this that could have been avoided had the cyclist given the proper, “On your left” to warn the foot traffic on the path that they are approaching.

I do feel bad about what happened this morning, but cyclists please, give a warning as you approach foot traffic on the paths! At the very least you’ll be protected from the possible face full of spit.
