Download Energy Systems For Fat Loss

Short in duration
Most powerful energy source we have
about 8 seconds of work
Can be replenished after about 2-3 mins of rest
Work:Rest = 1:10/12 (approx)
ATP = 2-3 seconds
Simply comes down to the increase
of energy compared to the intake of
energy.
Fat Loss
EPOC (Excess Post Oxygen
Consumption)
when your metabolism is still raised
from training where the need for
more oxygen is still high - More
energy after the fact
can be from 12-24 hours and
possibly greater
CP = 4-5 seconds
ATP is stored in the muscle cells
(contains energy)
Myosin Cross bridges (remember
Actin and Myosin?)
Creatine Phosphate when broken down in exercise
releases a lot of energy
Knowing Our Sh*t!
ATP
Adenosine Triphosphate
Every muscle contraction requires
the use of ATP
Think about it as US Dollars - can
easily be exchanged for other
currencies
Known as the $ of the body
ATP-PC
Anaerobic
Also known as ‘without oxygen’
Training Styles
Lasting for merely seconds, you
could possibly hold your breath
(without oxygen) for this activity
30 seconds to 2 mins of work
Anaerobic Training
Aerobic Training
Glycolytic System
Interval Training
think about a 400m run - this would
be a good example
When you see ‘glycol’, think
glucose
Carbs are important here
When you see ‘lytic’, think break
down
Often referred to as...
Fast / Slow
Alactic / Lactic
Anaerobic / Aerobic
Energy Systems
Training combat sports - this
system needs to be trained
part of the aerobic system
When exercising, you increase your
breathing rate to get more oxygen
into the body so more oxygen goes
to the muscles
2+ mins of work required
kicks in when all the ATP-CP and
muscle glycogen empties out
Energy Systems For
Fat Loss
Oxidative System
This system is known for it’s lactic
acid effect, presence and build up
Your body can’t do this fast
enough, therefore it calls on stored
energy to become pyruvate
(glycolysis)
Note: Lactate and Lactic acid are
not really the same
one of the by products when lactic
acid is produced is heat
Increase amount of hydrogen Ions
75% of lactate produced helps to
buffer energy
Not enough oxygen to perform?
Pyruvate turns into Lactate to fuel
the muscles (can be 1-3 mins for fit
people)
25% can leak into the blood
The fitter you are, the less you’ll
find in the blood
which is how we test for blood
lactate levels
can take a while to get going but
when it kicks in, it’s basically
unlimited
Gluconeogenisis
Low in output and force generation
hopefully where it’s about oxidising
CHO, F and (hopefully not) PRO
occurs in the mitochondria
Glycogen
Glucose
The Krebs cycle is often know as
the oxidative system
Pyruvic Acid
Energy
(O2 Present)
ADP
Krebs and ETC
ATP
Energy Again!
CO2, H2O, Heat
P
Means with oxygen
happening in the mitochondria
Produces heat, CO2 and H20
Note: There are 38 molecules of
ATP from 1 glucose molecule
Gluco = Glucose (Sugar)
Lactate can get shuttled back to
the Liver
can also use triglycerides as fuel too
36 molecule plus O2 (2x oxygen
molecule = 38)
Note: active recovery is required to
remove waste products from
muscle
Used as useable glycogen and ATP
