so let’s talk about endurance exercise and your heart okay there’s a

really good book if you do endurance exercise you need to get this book

it’s called the haywire heart how too much exercise

can kill you and what you can do to protect your heart

by chris case in john manderola one third of marathoners experience

dilated ventricles okay so you have the heart is four

chambers there’s two primer pumps they’re called

atriums then you have two major pumps which are ventricles so what happens

with athletes is they start to develop dilated ventricles or in the large

ventricles on one side so it starts getting

bigger there are indications of heart muscle damage

and cardiac fibrosis that scar tissue within the heart

and that can develop in all sorts of problems with the heart one would be

ventricular tachycardia which is one type of arrhythmia

it’s kind of a short circuiting what the authors talk about in this book

is mainly doing exercise for over one hour

every day sustained endurance exercise five days a week week after week after

week what happens is it creates structural

and functional changes within the heart now because the heart is becoming

stronger and more efficient and it pumps up more

work and oxygen the heart rate comes down and

that heart rate can come down from a normal heart rate which is like 72

to 60 to 50 to 40 to sometimes even 30. because the heart doesn’t have to

work that hard everything is very very slow

okay and that’s healthy right well what happens is you also get

cardiomegaly so the actual size of the heart can get bigger one

side of the heart can become bigger than the other side

depending on certain variables and the name for

something getting bigger is called hypertrophy so the problem is

having an imbalance from the left side and the right side

because the heart has various things in it that create

rhythm they’re called pacemakers you have two primary pacemakers

but you also have a backup system and even another backup system i don’t

want to get into the details of that but you just need to know that there are

certain pacemakers of the body that are all supposed to be coordinated

the problem is when the heartbeats start going down too

low that can trigger or alter

certain secondary pacemakers in the heart

and that can create extra beats okay you have

premature atrial contractions or premature ventricular contractions

so we have this situation we have this real strong healthy heart

which is not pathogenic that’s giving these

arrhythmia problems so in the book there’s some great case histories of

many people that have gone through this actually it’s very very common

and what they did to handle these extra beats

the biggest thing is to cut back on the exercise the problem with

sustained endurance exercise is you’re working

against the body’s natural rhythms because anything sustained is very very

stressful on the body if you’re an athlete and you’re noticing

some of these extra beats what’s recommended is you start to cut

back on your exercise you may even want to do interval

training because that’s erratic and it works with

the body it’s less stressful than sustained

exercise and get the book read it there’s a lot

more details to talk about in this video i mainly wanted

to communicate to the endurance athletes to bring up some awareness on the fact

that even though they can have a very healthy heart

you could have a problem with arrhythmias and there is something you

can do to reverse this if you have the

knowledge i’ll put a link down below of this

book check it out and thanks for watching
