Energy System Development
PETH42
Observe People in the Cardio
Room
• Leisure Jog on the treadmill
• Reading the paper while on bike
• Watching news on eliptical trainer
– Are we working hard enough?
– Are we challenging the body?
– How far vs. how fast? Quantity vs. Quality
Purpose of ESD
•
•
•
•
Burn calories
Improve function of heart and lungs
Build endurance
Challenge body so that it can adapt
“Progressive Overload”
We’re Forgetful as Adults
• Who was picked 1st in grade school
• Speed & power =increased muscles and
leaner body
• Burn calories, increase flexibility, improve
nervous system
• Ever seen a fat sprinter?
Verstegen Questions Methods
• Keeping HR in “fat burning” zone
• Training: plow horse or thoroughbred
• What do you think?
The 3 Energy Systems
• 1. Anaerobic Glycolysis
• 2. Phosphagen system
• 3. Aerobic system
• All systems are active, but participate more
according to intensity of activity
Anaerobic Glycolysis
• High intensity up to 3minutes
• Handle high acid
concentrations
• Fiber types?
• Active recovery
• Work/Rest ratio 1:2
QuickTime™ and a

are needed to see this picture.
Phosphagen System
• High level work up to
12 seconds
• Fuel in muscles used
• ATP-CP
• Inactive recovery
• Hypertrophy of type II
• Work/rest 1:3, 1:6

Aerobic System
• Work beyond 3
minutes
• Requires oxygen to
make energy
• Primary fuel at rest
• Work/Rest Ratio 1:1
• Marathons, distance
swimming, Ultras

Can you Guess the Primary
Energy System?
• Intensity?
• Duration?
• Think Fiber Types
• Explosive or paced

Guess this Energy system
• Name the primary
energy system for
baseball
• During active times,
which are few and far
between.

Soccer?
• There’s a lot of
jogging or paced
running
• But, there’s also
sprinting
• What’s the fuel source

Football?
• There’s a lot of
standing around
between each 5-7
second play
• But, the movements
are explosive
Basketball?
• Name the energy
system based on what
you’ve learned from
the previous slides

Effect of Event Duration on
Primary Energy System Used
Phosphagen System
0 - 12 sec, very intense, Anaerobic
Anaerobic Glycolysis
30sec - 3min, heavy, Anaerobic
Aerobic System
> 3 min, light, Aerobic
