6. 1. Anaerobic A-Lactic
(ATP-CP) Energy System
Adenosine
triphosphate (ATP)
is the source of
energy for use and
storage at the cellular
level.
Anaerobic A-lactic or ATP-CP is a
dominant source of muscle
energy for high intensity physical
activities. It provides high bursts
of startup energy that lasts
around ten seconds or less.
7. Many activities have a high dependence on the phosphagen system.
Success in team sports, weightlifting, field events (e.g., shot put and
discus throwing, jumping events), swimming, tennis, and so forth.
All require short-term singular or a limited number of repeated
intense muscle contractions. It has long been theorized that during
the initial 10–15 seconds of exercise that creatine phosphate was
solely responsible for ATP regeneration

9. 2. Anaerobic Lactic
(Glycolytic) Energy System
Same as with ATP-CP,
the anaerobic lactic
system does not require
oxygen but is capable of
supplying energy for
high intensity activities.
Anaerobic lactic is also known as
the glycolytic energy system, an
energy system that supplies
energy for medium to high
intensity physical activities.

12. 3. Aerobic (Oxidative)
Energy System
Aerobic energy system,
compared to ATP-CP and
glycolytic energy system,
requires much longer oxygen in
muscles in doing physical
activities like long distance
swimming, running, and playing
Aerobic energy system provides
energy for low intensity physical
activities that last from two minutes to
a few hours. Aerobic energy system
continually produces ATP energy to
muscles as long as oxygen is available
to muscles in the body. Unlike
anaerobic lactic system, aerobic energy
system does not produce lactic acid
since oxygen is available to the
muscles.
