Outlines
🏋️♂️ Introduction to ATP-PCr Energy System
The video begins with an introduction to the ATP-PCr energy system, also known as the anaerobic alactic system, which is crucial for fast movements and initiating all movements without the need for oxygen. The speaker emphasizes that energy systems work interdependently, like pots on a stove, and the ATP-PCr system is the first to be activated. It provides immediate energy through the breakdown of ATP stored in muscles, which lasts for about 2 to 3 seconds. The process involves ATPase cleaving off a phosphate molecule, releasing energy for various bodily functions. The speaker also explains the role of phosphocreatine (PCR) as a reservoir to regenerate ATP, extending the energy supply for high-intensity movements up to 10 seconds.
🔁 ATP-PCr System's Role in High-Intensity Movements
This paragraph delves deeper into how the ATP-PCr system extends high-intensity movement capabilities. It discusses the role of supplementation with creatine to increase PCR levels, which in turn can regenerate more ATP from ADP, thus sustaining intense exercise for about 10 seconds. The speaker also mentions an alternative pathway involving DNA kinase to produce ATP from two ADP molecules. The byproducts of ATP-PCr, such as phosphate and ADP, trigger the breakdown of glycogen and glucose, preparing the body to switch to the next energy system, the aerobic glycolytic system. The video concludes with an invitation for viewers to ask questions about the ATP-PCr energy system.

Highlights
Introduction to the ATP-PCr energy system, also known as the anaerobic alactic system, which is responsible for fast movements and initiates all movements without the reliance on oxygen.
The ATP-PCr system allows for instant movement and is the first energy system utilized when we start any physical activity.

ATPase enzyme cleaves off an inorganic phosphate molecule from ATP, releasing energy for various bodily functions.
The ATP-PCr system has two components: ATP storage in the muscle and the resynthesis of ATP from ADP and phosphocreatine (PCr).
Phosphocreatine acts as a reservoir to resupply ATP, extending the duration of high-intensity movement to about 10 seconds.

The byproducts of the ATP-PCr system, such as ADP and inorganic phosphate, activate the breakdown of glycogen and glucose, preparing the body for the next energy system.
The energy systems of the body are not independent; they work in concert with each other, with one system's byproducts often triggering the next.
The ATP-PCr system integrates with other energy systems, such as the anaerobic glycolytic system, to meet the body's energy demands during sustained activity.

Transcripts
hey do they make Smitty Graham here from
exponential performance coaching welcome
back to another whiteboard Wednesday and
today we're going to jump into the
second video of our energy systems
series and we're going to be talking
about that in aerobic ATP PCR energy
systems let's get into it
[Music]
do they mate welcome back to another
whiteboard Wednesday in today's episode
we are going to be digging into the
first of our energy systems in this
energy systems series the first energy
system we're going to be covering is the
ATP PCR energy system or as it's
sometimes known that anaerobic electic
system now this unity system is
responsible for all of our fast
movements but it also initiates all of
our movements as well and what it allows
us to do is to move instantly without
the reliance of oxygen once we get
moving our other energy systems kick in
too and to gear so to speak and we and
we move through into those more
sustainable energy systems but this
instantaneous energy system allows us to
spring into life move if we need to
these kind of two components of it and I
find that a lot of people get confused
about that ATP PC our energy system so
what I want to do today is try and break
it down a little bit and hopefully
explain it in a way that you can that
you can grasp now just remember none of
our energy systems work independently of
each other and I like the analogy of
three pots simmering on a stove top and
then what we do is we just dial up the
heat on a different pot depending on
what we're trying to cook so to speak
and hopefully that becomes a little bit
clearer as we move through things but
there's a dependency between the energy
systems so ATP PC our energy system
there's quite a two components of it and
that's why I've got this dashed line
down the middle of the board here to try
and hopefully get that concept over to
you first of all we've got what's
happening in the muscle the ATP storage
if you remember back to our last video
there's a small amount of ATP stored in
the muscle about two to three seconds
depending on who you are and your
training status so this ATP will
remember this molecular makeup here
this ATP can be used instantly so what
happens is ATPase this here Cleaves off
this in phosphate molecule and so this
phosphate molecule now is floating free
in that process energy over here this
big lightning arrow
energy is released okay that is energy
for movement for digestion for neural
stimulus whatever it might be and in the
process we're left with an ADP and a
free phosphate molecule because this guy
here is now floating around so that is
the first instantaneous energy that we
get
we've got enough energy to do that for
about 2 to 3 seconds of movement after
that the ATP runs out so what we need to
do is we need a bit of a reservoir and
this is what the PCR aspect over here
does it acts as a bit of a reservoir to
resupply this so that this process can
happen a few more times so what we do is
we take this ADP over here and we come
over to this side and what we do is if
we get an ATP molecule what's remember
there's just an ATP adenosine
triphosphate
but with this molecule gone this
phosphate molecule so now there's the
adenosine SV and then two phosphate
molecules adenosine diphosphate so we've
got our adenosine diphosphate over here
if we couple that with phosphocreatine
or PCR using creatine kinase to help
this reaction along what actually
happens as we produce another ATP
molecule which is pretty cool so we're
left with ATP molecule over here and a
free creatine floating around in the
system so this here gives us some more
energy and this process here can happen
again
so the ATP cleave off one of those
phosphate molecules bond more energy is
released and what this allows us to do
is extend out our movement time to about
10 seconds of high-intensity movement we
can increase the capacity with
supplementation if we have a look at PCR
if we have more PCR floating around in
our system then we have more PCR to pick
up the ADP molecules and turn them back
into ATP and we can do that by consuming
creatine okay and some of you are
probably quite familiar with creatine
supplementation the other way we can do
this is that we can take to ADP
molecules and with the help of a DNA
kinase we're able to actually make
another ATP molecule as well and then
that feed back over here
and we were able to get that system
happening again so this allows us about
10 seconds of energy we've got about 2
to 3 seconds stored in the muscle when
that runs out we dip into this reservoir
over here and that allows that high
intensity exercise intensity to be
maintained out to about 10 seconds now
the really cool part of this is the
whole system's integrate with each other
as the products
ANP which is released over here after
this reaction happens phosphate what you
can see is released over here when this
reaction happens and adp again released
over here in this reaction happens these
all activate the breakdown of glycogen
and glucose to mobilize them our next
energy system to
to get an aerobic glycolytic energy
system because if there's a lot of work
happening and our body knows that we're
going to need to repay this energy
deficit so we've been a spark up and
next energy system which is our
anaerobic oolitic energy system and the
byproducts of this energy system check
this mixed one into gear and that's what
we're going to talk about in a next
video if you've got any questions about
the ATP PCR energy system fire them
through and I'll do my best to answer
them I hope that helped
