20 burpees, 30 box jumps, 40 kb swings, 30 box jumps 20 burpees

We did a mobility wod before and after today’s workout. The first was a super friend stretch for the upper part of our back, or the thoracic spine. Always good to get into the tight hot spots that not only effect our work outs but our everyday tasks. The finishing mobility was for our knees. We got into the super patellar pouch above the knee and then worked all the tissues above and below, the calf quad and hip crease. Yummy!

For some reason this work out was prone to inciting people to puke after…more than any other we have done in a long time. So I decided to do a little research on why people puke after or during a workout. Here is what I found.

For probable reason that someone may be inspired to puke during or after a workout…

1. Dehydration
2. Heat exhaustion
3. Vagal reaction
4. Hyponatremia                                                                                                                                                        5. Not Breathing…..

1+2. Exercise induced sickness from dehydration and heat exaustion is usually because of the increased effort causing you to sweat out lots of fluids that are not replaced.

3. Vagal Reaction. Exercise induced sickness from the vagal reaction is more rare but happens. Most folks heart rate increases when they are excited, scared, or doing a hard workout. However, a small percent of people experiance the opposite. Thier heart rate slows, blood pressure falls, and they can experience intense nausea with or without vomiting or getting sick.

Here is a quote from National Library Of Medicine “Vagal reactions” may follow sudden emotional or physical strain in “vagotonic individuals” and are usually benign. In the case described, emotional stimuli caused life-threatening vagal reactions in a “healthy individual.” Implantation of an artifical pacemaker was necessary to control the attacks.

4. Exercise induced sickness from Hyponatremia is caused by a sudden drop in concentration of sodium in the blood. When you do a hard workout with heavy exercise and sweating, your body turns on the pituitary gland in your brain to produce a hormone called ADH, or anti-diuretic hormone. This hormone tells the kidney to hold on to free water or water that does not contain salt. If your salt and other mineral intake is too low, then the concentration of sodium in your blood can drop. For some reason people that take anti-inflammatory medications like Motrin, Advil, or Aleve may be more at risk of hyponatremia.

5. Gastrophageal reflux brought on by the valsalva maneuver or holding your breath while you push hard. BREATH SO YOU DONT PUKE!A weak esophageal sphincter or a looseness of the little ring of muscle that separates your stomach from the esophagus. This is more of a little regurgitation instead of a full fledged puke.

If you are shaking when you puke then is could also overstimulated your central nervous system from intensity techinuques or just going past your limits and your body wants you to stop! So it makes you puke!

And, an unnumbered extra….

The last thing that may cause puking is a change in your blood pH produced by the anaerobic metabolism of pyruvic acid. If you workout harder than usuall and your body cant get rid of the lactic acid quicker than you are producing it a build up occurs and your ph goes out of whack. You become toxic and puke to try to clean your system.
