Document Summary

Endurance: 2 minutes to hours (prolonged endurance >90 minutes, any intensity, examples: walking, jogging and distance running, long distance cycling, long distance swimming, and dance aerobics. The body will use creatine phosphate, glycolysis, and the krebs cycle for energy production. Synthesized by the liver or obtained through diet. Vegetarians tend to have lower amounts: depends on availability of aa, and how much their body can make. Takes 1 to 2 minutes if cp stores have been substantially reduced. Creatine phosphate is broken down, releasing its and pi, which is then used to dephosphorylate adp into atp. This is very rapid, one-step chemical reaction, catalyzed by this enzyme. It increases muscle cp stores (by as much as 20%) Allows athlete to work harder (studies also show it may possibly enhance recovery; not conclusive) Some athletes are low responders , some are non-responders . Researchers generally use 20g for first 5 days then 5-10g daily thereafter.
