Calories burned in a sprint Tri at all out pace Quote | Reply

I just did a sprint tri and I feel like a I could eat paper I am so hungry. I know it doesn't burn many calories but is there some sort of afterburn with the all out effort. I don't get this hungry after a 4 hr bike ride.

I imagine your hunger has more to do with depleting glycogen and low blood glucose levels than the total calories burned, per se. Hard workouts, especially of any duration, always make be very hungry.

Yes there is an after burn to exercise, but it's relatively minor.

^^^^This.

Depending on your body weight (and to a minor extent the course), a sprint probably burns 800-1200 kcal. That's not zero, but it won't give you a free pass at In-n-Out. A shorter race will burn a higher % of carbs vs. fat; on your longer rides you aren't quite as reliant on carbs.

The key thing is to put back some carbs and a bit of protein soon after the race finishes (within 1/2 hr.). Get some fluid to fill your stomach a bit and start rehydrating, have a powerbar and a protein bar. On the way home have a regular lunch.

Hunger soon after a sprint tri depends more on what you didn't eat for breakfast... and the night before. You may have a large caloric deficit depending on how much you restricted intake.

Huh. Usually I'm a bit sick to my stomach after short races/intervals. No way I could eat a house down.

Long course, on the other hand... my pantry screams in fear when I get home. :-)

This touches on a question I have been wondering about - does fitness play into calorie burn?

For instance - lets say Matt Reed and I complete the same 7 mile run in an hour, and our weights are equal.
Even though that may be a mellow 'recovery run' for him, it is a tempo run for me.

My understanding is that equal mass covering equal distance in equal time (running economy aside) means
we burn the same calories, even if he barely breaks a sweat and I'm flat out.

True or False?

Other people have done the math but research has determined that for really high intensity training/racing you burn more calories (200-400ish depending) since your body is working in overtime to repair as that is very taxing on the body. Still not enough to feel like you need to eat paper, but something to consider.

Calories burned in a sprint Tri at all out pace = Calories burned in a sprint tri at a total cruise pace (but takes twice as long to complete)

This has always been my understanding also, and I think that this is why the top athletes have to eat so much, cause they're burning around 50% more calories/hr than we do (all things being equal, e.g. Reed would run 10.5 miles in an hour for his tempo run), plus they can tolerate more hrs of training per day than we can.

Are you saying the elite athlete may burn fewer cal/mi due to his/her efficiency???

True for the run, but not correct for the bike. Riding faster burns more Cals/mile.

yes
They will spare alll the energy poor runners will spend bouncing

OK, I can see that, using more energy to generate more watts and go faster. However, in this particular case we were just talking about running, but good point:)

Right, understand that and actually, if you look back at TriDevilDog's original post (#9 above), he says "neglecting running economy", so really that is what we were talking about, but ya, you bring up a valid point. Even more so this is true of course with top swimmers in that hey are so smooth that they burn many less calories at say a 1:05/100 scy pace than we would. On the other hand, it is fairly well documented that Phelps ate somewhere around 8000 to 9000 cal/day when training hard at a weight of around 190 lbs. Of course he was quite young at the time, e.g. 21-22-ish, plus he may have been gaining some muscle mass at that time. I think he did gain around 10-15 lbs between the '04 and '08 Olympics.

x2. A 30 minute criterium race yesterday, I burned ~600 cals. I wasn't all that hungry, but given the heat, I had a huge need to replace fluids.
