Do sprinters breath during the 100m? What HR do they get up to and how quickly?

My dear, the verb is "breathe."

"Breath" is a noun.

During a 100-meter sprint, sprinters do breathe, but their breathing patterns are different from those in longer races. The race is very short (typically around 10 seconds or less), so breathing is not as critical as in longer events. Sprinters might take a few quick breaths before the start, hold their breath for a significant portion of the race, and take a few rapid breaths towards the end. The emphasis is more on maintaining form and explosive power rather than oxygen intake.

Regarding heart rate, sprinters can reach very high heart rates during a 100-meter sprint. Elite sprinters' heart rates can reach up to 180-200 beats per minute. The heart rate increases very quickly, often within the first few seconds of the race, due to the sudden and intense physical exertion. The exact heart rate and the speed at which it increases can vary based on the individual's fitness level, conditioning, and specific physiological factors.

HR jumps rapidly, probably to maximum, not because of burning oxygen but because of the so-called "skeletal muscle pump."

The lower legs pump venous blood back up to the heart. The heart has to then pump faster or be swamped with blood and explode or whatever.

Ran at the collegiate level. I was always taught that you should never be taking more than 10 breaths during a 100 and as far as I am aware most high-level sprinters are taught the same thing.

I can’t remember the specifics, but in a USATF coaching class I took, a physiologist showed data that suggested breathing was a “waste” of energy for efforts up to 40 seconds.

I do personally know a 44 mid 400 runner that claimed he didn’t breathe in his 400’s. He puked after almost every one of them, maybe he really wasn’t breathing.

Most 100m guys take 3 breaths on average. It's more about control as mentioned above.

Matthew Boling told me he takes 55 breaths when he races the 100m, with 35 of them being in the last 20m.

Here's some info for you:

Carl Lewis once said that he would never race distances where he had to breathe.

Yes. In addition to that sprinters' hearts function a little bit differently so their heart rate increases rapidly but also drops very rapidly after the race.

you can elite 400 runners breathing at the end of the 400..

Say what now?

the goose was at 130 at the start line of ot and seemed to be 180-190 during his run. can probably catch it on youtube/replay

this is chatgpt — but it's right! AI is coming for the message boards...

Yup. This is documented in either Science of Hurdling and Speed by McFarlane and/or Charlie Francis Training system. I've had inexperienced kids hold their breath the entire race then improve a lot when they breathe.

Hold breath for the start until 20 or 30m, breathe out as you're hitting top speed, then breathe in and out once or twice more in the race.

Nothing really to add, just that not breathing in a 400m race is an absolutely psychopathic action.
