in the primordial soup love the you know
early early single-celled organisms you
had glucose being metabolized in the
absence of oxygen through a 20 step
process down to a chemical called
pyruvate and that's kind of how things
went for a period of time and those
organisms can only get so big because
you had to have an energy gradient
across the cell membrane well as you get
bigger your volume if you're going to
double your size your volume increases
by a factor of eight two times two times
two is eight but your surface area that
which creates the energy gradient only
increases two times to four so if you
double your size your ability to
generate energy drops by 50% over time
other organisms developed that created a
cell membrane inside of a cell membrane
that was all folded up on itself so it
had a lot more surface area to generate
energy these were little proto bacteria
and they fed off the waste product of
these single-celled organisms and they
can make a lot more energy because they
had a lot more surface area because of
everything folded inside this membrane
inside of a memory well eventually those
things infected these single-celled
organisms and had a symbiotic
relationship those became mitochondria
so that is the whole relationship
between the anaerobic component
metabolism and the Arabic component of
metabolism so the only way to really
ramp up the aerobic component of
metabolism is to deliver substrate more
quickly to it so the only way to
stimulate the aerobic sub segment of
metabolism is by ramping the anaerobic
portion of metabolism as fast and as
aggressively as possible so that's why
we're finding now all these studies on
high-intensity interval training
producing equal
aerobic adaptations in a four-minute
Tabata protocol as you get from 45
minutes of steady-state well the same
thing is true of resistance training and
what it comes down to is the way that
you can get at that metabolism and make
it crank as fast as possible to deliver
substrate to the mitochondria is by
doing mechanical work with muscle that's
the only way you can get at that system
it only stands to reason that the higher
the quality of the mechanical work with
muscle the more you can invoke that
entire process and resistance training
just happens to be the mechanism by
which you can get the highest quality
mechanical work with muscle to drive
this whole process now if we take you
know Kim Cooper aerobic from Kenneth
Cooper's aerobics from the 1970s that
said what happens in the mitochondria is
somehow linked directly to the heart and
the vasculature that makes no sense
physiologically at all the heart and
blood vessels service the entire
functioning of metabolism the entire
cell not a sub-segment of the cell so it
turns out that the best cardiovascular
training you can do is the type of
training that invokes the totality of
metabolism to the most aggressive degree
possible and that just so happens to be
properly performed resistance training
