This ever happen during a workout?

[Gorilladf]

Going along having a good workout... between sets... and you......yaaawwwn.

Huh?

This has happened to me more then once. I'm not really tired. Pumped. Music blasting, and all of a sudden I'll just yawn between sets.

Go figure!

[SP1966]

Yes, I go to the gym at 5:30am, I tend to yawn alot at that hour!

[phikappa]

Used to happen a lot at an old gym of mine. Not just me, either. We just attributed it to poor air circulation. I've never yawned as much in any other gym.

Some recent research indicates that yawning is caused by an excess of carbon dioxide and lack of oxygen in the blood. Thus perfectly normal while engaging in strenuous activities.

I yawn throughout lifting (between sets).

I believe this ^ is the case (this has been discussed here before), and I think there's another explanation for it, but I can't remember. In fact, on days when I lay down on the bench to do BP (which is usually when it happens to me), I usually have great sets. It's not just a morning kinda thing.

You yawn to stop the brain shutting down - sudden oxygenating of the blood - makes sense during workouts.

And here I thought it was weird that I yawn during workouts. I seem to find myself doing it quite often. I work out in the afternoon so sleepiness isn't the reason.

[GreenWave1]

Yup.

Just a couple of weeks ago on ScienceDaily I read that we yawn late at night to get a rush of air into our skulls to cool off the brain, so it'll fall asleep easier. If that's the case, maybe your brain is overheating.

I don't know. I think it would be interesting to experiment lifting in various temperatures and rating the number of yawns per session.

Happens to me every w/o. I w/o around noon so I know I am not tired.

Here's an article that is basically the same as 2 others I just found/read:

By Norma Nehren, M.D.

Q: ?I?ve noticed that when I work out with weights, in about a half hour I start to yawn constantly. Other people notice, too, so it?s embarrassing. Recently I?ve also had trouble with being a little lightheaded if I bend over then stand up. None of these things happen when I swim or play racquetball, so what?s so different about lifting weights??

A: Yawning (also known as oscitancy) is contagious. While reading this article, do not be surprised if you yawn at least five times. I know I will. (Yawn.) Just thinking about the act of yawning can set off a yawn. It doesn?t necessarily mean that you are bored or sleepy.

Although I would like to explain away your yawning by telling you that you are not breathing correctly during your weightlifting routine, that would be too simplistic an answer and not necessarily correct.

No one really knows why people yawn. The dictionary will describe a yawn as a reaction to fatigue or boredom. There are several other theories. (Yawn.)

Oxygen and carbon dioxide balance is usually the assumed cause of yawning during exercise. Yet in the last 20 years a handful of studies have shown that treating people with high levels of either gas makes no difference in their rate of yawning, even though their breathing rates change significantly. (Yawn.)

On the other hand, one way to look at those studies is to recognize that in all of them, there was no control on the rate of breathing. When the balance of oxygen and carbon dioxide changed in the environment, the people studied just changed the rate at which they breathed to accommodate for it. When you are exercising, or tired, or bored to tears, you may find that your breathing has changed in such a way as to disrupt your oxygen to carbon dioxide balance. You may be breathing more shallowly, either too fast or too slow, and use yawning as a way to reset the balance.

When carbon dioxide builds up, you begin to feel sleepy or dizzy. It works great for helping you fall to sleep or diverting an anxiety attack, but doesn?t work so well in the gym. (Yawn.)

Pandiculation is the act of stretching and yawning. Similar to the stretching your other muscles do before and during exercise, the mouth, diaphragm and lungs stretch out with a yawn quite commonly during or before strenuous activity, at the same time increasing the heart rate and blood pressure slightly.

It could be a combination of physiological and psychological effects. The hypothalamus, which controls appetite, blood pressure, heart rate, sleep cycles and metabolism, also controls the yawning response. (yawn)

Yawning is a very social behavior as well. We begin the response of yawning while still in the womb, yet it does not become a contagious reaction until age 18 to 24 months, a sign that the social aspect of yawning develops along with our other social skills.

The evolutionary development of the yawn for social interaction is one theory for this response. Almost all animals yawn. It may be a way to coordinate behavior or communicate changes in a group. Thus the contagious nature of a yawn.

In dogs, yawning is a calming behavior used socially to calm all members of the pack during stressful situations. It?s kind of like saying look at my big teeth that I?m not using in aggression; I?m not snarling, I?m OK, you?re OK. (Yawn.) Seems a lot like teenage behaviors.

One of the best sources for medical information on the Internet is MedlinePlus, a service of the National Institutes of Health and National Library of Medicine. They report that although yawning is normal, excessive yawning can indicate a problem. Sleep disturbances that result in excessive daytime sleepiness, as well as heart and blood pressure problems, can cause yawning responses.

Your physician may want to check for anemia, look at your blood pressure, your oxygen saturation, examine your heart, or have you get an overnight sleep study. There also are certain medications that can make you yawn; but that effect would be present all day, not just while you were exercising. Antidepressants that affect dopamine or serotonin can increase yawning, while opioid pain pills can inhibit yawning.

Weird I only used to do it on the hip and groin adductor machines--went away after a while

Soooo thats why my wife yawns during sex.

[crupiea]

I think it has something to do with stress the central nervous system. I hate to admit it but I have cried for no reason when doing particularly heavy sets of squats and deads.

It just comes on you when your system is in a stressed state. Those are always the best workout days.
