[QUOTE="chopair, post: 208203, member: 26539"] [b]Probable Arm Pump explanation[/b] Arm Pump is caused by the metabolites of the anerobic work performed by the foreams. Anerobic excersise "burns" glycogen (stored carbs) in the muscle. The "exhaust is mostly lactic and pyruvic acid. This is all part of the Krebs cycle if you are interested in greater detail. A possible explanation for de-pumping experience that you are experiencing is that you have burned all the glycogen available in you forearms. Therefore, there is no fuel left to produce the metabolites that cause arm pump. In this case, the only mechanism left to produce grip strength is aerobic. This process burns oxygen supplied by the muscles blood supply. It is not capable of producing the same maximum stregth but has the advantage of being continuously availabe. As a pedal powered cyclist, I was part of as research study at the UCI Human Performance Lab. that studied this effect on racing cyclists. [/QUOTE]
