ATP-PCr
•Very limited storage of high energy phosphates

•Enough stored to power - short duration and high intensity activities
-~1 min brisk walk
-20-30 sec run/jog
-5-6 sec sprint
-100-m sprint
-Thrusting a heavy weight upwards

•High-energy phosphates
-ATP
-PCr (intramuscular PC)
Glycolysis
•Forms ATP rapidly (not as fast as ATP-PC system)

•Performances of short duration and high intensity requiring rapid energy transfer
exceeding that supplied by phosphagens.
-400-m sprint
-100-m swim
-Multi-sprint sports
-Exercise lasting between 30-90 seconds

•Rapid ATP formation in glycolysis has consequences...
-ATP "pay-off" not big (2 ATP/mol glucose)
-Only uses CHO as fuel
-Lactate formation
Blood lactate accumulation
Lactate is always being produced

•Only at high exercise intensities does it accumulate
•Formed in muscle...spills over to blood
•Blood lactate threshold (or onset of blood lactate accumulation or OBLA): When blood
lactate begins to increase exponentially
•"Lactate Threshold": The intensity of exercise where lactate begins to accumulate
•Post workout, lactate removal rate increases after light exercise compared to no
exercise
Aerobic metabolism
•Provides means to synthesize large amounts of ATP
•Exercise exceeding 3 minutes
