Triple jump at the Olympics to 1912). The standing jump competitions were dominated by Ray Ewry, who won the 1900 Olympic standing triple jump title and defended it four years later. His clearance of to win the inaugural competition went unbettered as the Olympic record for the event. Ewry took Olympic three gold medals in standing jumps in both 1900 and 1904, then won the standing high and long jumps at the 1908 Olympics, as well as the 1906 Intercalated Games. Standing jump events had been a relatively common type of athletics event at the end of the 19th century, but became increasingly rare at
Committed step Committed step In enzymology, the committed step (also known as the "first" committed step) is an effectively irreversible enzymatic reaction that occurs at a branch point during the biosynthesis of some molecules. As the name implies, after this step, the molecules are "committed" to the pathway and will ultimately end up in the pathway's final product. The first committed step should not be confused with the rate-determining step, which is the slowest step in a reaction or pathway. However, it is sometimes the case that the first committed step is in fact the rate-determining step as well. Metabolic pathways require
