They don’t mention it, but it could be due to gas.

Slump Over to Catch Your Breath for Faster Recovery

Listen to your body 😉

Exercise form is important for increasing your gains and protecting yourself from injury. But when’s the last time you thought about the way you hold yourself between sets?

The article suggests that the posture allows for better/deeper breathing, but nothing about it would also help with blood flow and pressure because you aren’t fighting gravity as much.  It also would support my experience with recovery from a sprint while cycling, but that would only apply to someone in an aggressive riding posture (seat higher than the bars/etc) that you’d find in road cycling.

My last triathlon last year, I passed someone who I saw start walking early on the run.  I figured like most they’d given up, passed them and didn’t think any more of it.  It wasn’t far down the route that they overtook me, and I got to see that’s how they attacked the run.  I don’t recall seeing what they did as a sprint, but it certainly worked for them to run faster for short periods with active recovery by walking.  I think they were out of sight by the 3 KM mark.  I’m tempted to try the strategy this year…

How Does Your Stomach Know When to Vomit?

There are several ways to induce vomiting in humans. Without getting too specific, they are all linked through the “vomiting center” of the brain, also known as the area postrema. The “vomiting center” is capable of responding to many different types of poisons, toxins, conditions, etc. In the case of eating something bad, remember that the stomach is a highly vascularized zone that also happens to have a massive nervous structure called the enteric nervous system.

Usually food poisoning that involves vomiting is caused by organisms that have preformed toxins, including but not limited to B cereus and S aureus. That delicious looking potato salad is teeming with toxins that have been pre-made by the bacterial species to wreak havoc on whomever might eat it. These toxins work within hours, causing inflammation in the gut.  This information gets relayed back to the vomiting center.  Once the brain registers that something is not right in your tummy, it stimulates muscles to close the pyloric sphincter (bottom of the stomach) and open the cardiac sphincter (top of the stomach) before activating the abdominal musculature and diaphragm to propel the harmful substance out of the stomach via forceful contraction.

What about a “strong” vs “weak” stomach?  A lot of why people throw up is mental – you have incredible subconscious control over puking.  Or it could have to do with innoculum – give someone a large enough dose of toxin/bacteria, and they’ll blow chunks.

The funny thing about it, you need your brains “permission” to puke, but your gut doesn’t need your brains permission for diarrhea.  If for some reason you ate something wacky that managed to get past the brain’s vomiting center detection, your intestines will flush with extreme prejudice.  Sometimes, a group of people who eat the same bad food can experience either symptom – vomit or diarrhea.
