Have you ever ever puzzled what operating 26.2 miles does to the physique? In case you’ve carried out it and hung out strolling down stairs backwards you would possibly have already got a reasonably good thought, however what’s occurring at a mobile stage? Is operating a marathon even wholesome?
Let’s be trustworthy, most of us have questioned if it’s good for us proper about mile 25 when every little thing hurts! And but…we do it once more as a result of one thing in us is aware of there’s good when DONE RIGHT.
Which is to say that you should have much less impacts from operating a marathon if you happen to’ve carried out a correct construct up, you’ve been power coaching and fueling.
Quite a lot of what I’m about to share from the science can have some folks pumping their fists and saying “see we advised you operating is unhealthy for you.” However that’s not likely the take away right here and most are very momentary results and don’t evaluate to the overwhelming well being advantages of lengthy distance operating.
That being mentioned, we aren’t claiming that marathon operating is in your well being. If wholesome and longevity is the main focus, I don’t know that 26.2 is on the record.
What Occurs to Your Physique After a Marathon
Coach Laura Norris and I dove in to the analysis to bust sure myths, discover solutions and aid you higher perceive why we push so laborious for submit marathon restoration time!
Right here I’ll summarize our key factors from the Tread Flippantly podcast, however you need to hearken to the complete episode embedded beneath!
And most significantly, notice that these items are occurring unbiased of your tempo!! Operating quicker doesn’t meant it impacts the physique much less.
So let’s dive in first with what occurs to your physique after operating and a marathon. Whereas a few of these can sound slightly scary, operating a marathon will not be unhealthy in your well being (assuming you haven’t any underlying circumstances).
#1. You Shrink
That’s proper! Operating generally compresses your spinal discs and so any run over half-hour will trigger you to be a bit shorter, with the length of the marathon you possibly can end as much as 1/2 inch shorter!
Whereas there could also be disc compression that results in us being shorter, the research say there isn’t a actual long run degeneration occurring. And we all know that redhydrating plumps them again up an one other examine confirmed operating may very well assist cut back degeneration
Past your discs, there’s really some loss out of your foot collapsing downward by as much as 5mm. Once more quick time period and certain muscle fatigue.
#2 Discount in Lung Perform
A 2019 evaluate in Sport Drugs discovered that you’ve got as much as a 15 to 25% decline in perform in your lungs and in your diaphragm muscle mass because of the fatigue of heavy respiratory for thus lengthy in a race. Once more, that recovers fairly shortly.
It simply means that’s why you’re feeling drained and out of breath, most likely simply strolling round after a marathon.
However once more, goes to point out that doing this race, operating is a complete physique sport. We see it affect your bones and your muscle mass and every little thing.
#3 Mind Fog or Heightened Feelings
The opposite factor that a lot of you could have most likely skilled is possibly you could have simply quite a lot of feelings on the end. I imply, I cry at each end line! However you might also really feel like I can’t actually decide or I can’t suppose to inform my household the place to fulfill me.
That’s mind glycogen that’s been depleted.
Your mind runs on carbohydrates. And even whenever you’re fueling your greatest, you’re most likely not fairly hitting the precise quantity that your physique and your mind is utilizing since you would simply be taking in a lot.
#4 Swollen Toes
We frequently discuss needing to purchase bigger sneakers as runners and that is because of ft swelling with extra time on them. The truth is, one examine confirmed they develop 4 to 8mm which is why we want that longer shoe otherwise you would possibly want a large on race day.
But in addition, your ft will swell extra AFTER end the race.
Blood circulation is now not being diverted to muscle mass, so it could begin to rush again to different areas like your ft. Presumably why these operating restoration sandals feels so dang good.
#5 Systemic Irritation
Okay, issues are infected…however what about your coronary heart?
The identical 2019 examine, they discovered that troponin ranges have been elevated for up to 4 days after a marathon. Troponin is a biomarker that signifies acute harm to the coronary heart muscle mass.
What’s really actually vital about this examine is the conclusion WAS NOT that marathons harm your coronary heart. It was extra a discover that if you happen to get bloodwork carried out proper after a race you’ll have elevated ranges of this and different markers like C-Reactive protein, creatine kinase, lactate dehydronase (mainly muscle, tendon, ligament harm).
It’s one other reminder that we don’t wish to leap proper again in to coaching as a result of there are issues you possibly can’t see or really feel occurring.
We cowl much more within the present, however these are among the highlights that assist reply that so widespread query of what does operating a marathon actually do to you??
And I hope, you possibly can see right here that the majority issues are very momentary, however certainly are vital and reinforce why resting is so essential!!
Is it true that you simply want in the future of restoration for each mile raced?
That is an adage that each Laura and I heard early in our operating careers. In some methods it is smart as a result of the longer the race, the extra restoration your physique wants.
However when you’ve been operating for awhile taking 26 days off of operating after a marathon won’t being solely crucial, relying in your objectives. That being mentioned, the elites do it!! They usually take a month and even 2 off after their large objective marathon race of the yr.
Once more, all of those information factors remind us that restoration is a lot greater than you “simply feeling able to run”. The physique is doing quite a lot of stuff behind the scenes that may really aid you to comeback fitter, after taking the suitable period of time to recuperate.
Normally, we advocate 10-14 days of no operating for just about everybody. Under you’ll discover further sources for a full submit marathon return plan.
What’s going to reduce the affect of operating a marathon?
As famous earlier, having carried out the suitable coaching is a large issue. It doesn’t imply that being tremendous effectively educated eliminates every little thing, nevertheless it actually helps.
If that is your first marathon, there’s doubtless going to be extra restoration wanted as your physique adapts to this huge new stimulus.
In case you fueled and hydrated effectively with pre and intra race carbs, you possibly can really assist to hurry up therapeutic.
And truthfully, let’s not fake being youthful doesn’t assist too. 🙂
